-# Contribute to Doctrine
-
-Thank you for contributing to Doctrine!
-
-Before we can merge your Pull-Request here are some guidelines that you need to follow.
-These guidelines exist not to annoy you, but to keep the code base clean,
-unified and future proof.
-
-## We only accept PRs  to "master"
-
-Our branching strategy is "everything to master first", even
-bugfixes and we then merge them into the stable branches. You should only 
-open pull requests against the master branch. Otherwise we cannot accept the PR.
-
-There is one exception to the rule, when we merged a bug into some stable branches
-we do occasionally accept pull requests that merge the same bug fix into earlier
-branches.
-
-## Coding Standard
-
-We use PSR-1 and PSR-2:

-
-* Keep the nesting of control structures per method as small as possible
-* Align equals (=) signs
-* Add spaces between assignment, control and return statements
-* Prefer early exit over nesting conditions
-* Add spaces around a negation if condition ``if ( ! $cond)``
-
-## Unit-Tests
-
-Please try to add a test for your pull-request.
-
-* If you want to fix a bug or provide a reproduce case, create a test file in
-  ``tests/Doctrine/Tests/ORM/Functional/Ticket`` with the name of the ticket,
-  ``DDC1234Test.php`` for example.
-* If you want to contribute new functionality add unit- or functional tests
-  depending on the scope of the feature.
-
-You can run the unit-tests by calling ``vendor/bin/phpunit`` from the root of the project.
-It will run all the tests with an in memory SQLite database.
-
-In order to do that, you will need a fresh copy of the ORM, and you
-will have to run a composer installation in the project:
-
-```sh
-git clone git@github.com:doctrine/orm.git
-cd orm
-curl -sS https://getcomposer.org/installer | php --
-./composer.phar install
-```
-
-To run the testsuite against another database, copy the ``phpunit.xml.dist``
-to for example ``mysql.phpunit.xml`` and edit the parameters. You can
-take a look at the ``tests/travis`` folder for some examples. Then run:
-
-    vendor/bin/phpunit -c mysql.phpunit.xml
-    
-If you do not provide these parameters, the test suite will use an in-memory
-sqlite database.
-
-Tips for creating unit tests:
-
-1. If you put a test into the `Ticket` namespace as described above, put the testcase and all entities into the same class.
-   See `https://github.com/doctrine/orm/tree/master/tests/Doctrine/Tests/ORM/Functional/Ticket/DDC2306Test.php` for an
-   example.
-
-## Travis
-
-We automatically run your pull request through [Travis CI](http://www.travis-ci.org)
-against SQLite, MySQL and PostgreSQL. If you break the tests, we cannot merge your code,
-so please make sure that your code is working before opening up a Pull-Request.
-
-## Getting merged
-
-Please allow us time to review your pull requests. We will give our best to review
-everything as fast as possible, but cannot always live up to our own expectations.
-
-Thank you very much again for your contribution!

-The Doctrine library is operating very close to your database and as such needs
-to handle and make assumptions about SQL injection vulnerabilities.
-
-It is vital that you understand how Doctrine approaches security, because

-# Upgrade to 2.8
-
-## Minor BC BREAK: Failed commit now throw OptimisticLockException
-
-Method `Doctrine\ORM\UnitOfWork#commit()` can throw an OptimisticLockException when a commit silently fails and returns false
-since `Doctrine\DBAL\Connection#commit()` signature changed from returning void to boolean
-
-# Upgrade to 2.7
-
-## Added `Doctrine\ORM\AbstractQuery#enableResultCache()` and `Doctrine\ORM\AbstractQuery#disableResultCache()` methods	
-
-Method `Doctrine\ORM\AbstractQuery#useResultCache()` which could be used for both enabling and disabling the cache
-(depending on passed flag) was split into two.	
-
-## Minor BC BREAK: paginator output walkers aren't be called anymore on sub-queries for queries without max results  
-
-To optimize DB interaction, `Doctrine\ORM\Tools\Pagination\Paginator` no longer fetches identifiers to be able to
-perform the pagination with join collections when max results isn't set in the query.
-
-## Minor BC BREAK: tables filtered with `schema_filter` are no longer created
-
-When generating schema diffs, if a source table is filtered out by a `schema_filter` expression, then a `CREATE TABLE` was
-always generated, even if the table already existed. This has been changed in this release and the table will no longer
-be created.
-
-## Deprecated number unaware `Doctrine\ORM\Mapping\UnderscoreNamingStrategy`
-
-In the last patch of the `v2.6.x` series, we fixed a bug that was not converting names properly when they had numbers
-(e.g.: `base64Encoded` was wrongly converted to `base64encoded` instead of `base64_encoded`).
-
-In order to not break BC we've introduced a way to enable the fixed behavior using a boolean constructor argument. This
-argument will be removed in 3.0 and the default behavior will be the fixed one.
-
-## Deprecated: `Doctrine\ORM\AbstractQuery#useResultCache()`	
-
-Method `Doctrine\ORM\AbstractQuery#useResultCache()` is deprecated because it is split into `enableResultCache()`
-and `disableResultCache()`. It will be removed in 3.0.
-
-## Deprecated code generators and related console commands
-
-These console commands have been deprecated:
-
- * `orm:convert-mapping`
- * `orm:generate:entities`
- * `orm:generate-repositories`
-
-These classes have been deprecated:
-
- * `Doctrine\ORM\Tools\EntityGenerator`
- * `Doctrine\ORM\Tools\EntityRepositoryGenerator`
-
-Whole Doctrine\ORM\Tools\Export namespace with all its members have been deprecated as well.
-
-## Deprecated `Doctrine\ORM\Proxy\Proxy` marker interface
-
-Proxy objects in Doctrine ORM 3.0 will no longer implement `Doctrine\ORM\Proxy\Proxy` nor
-`Doctrine\Persistence\Proxy`: instead, they implement
-`ProxyManager\Proxy\GhostObjectInterface`.
-
-These related classes have been deprecated:
-
- * `Doctrine\ORM\Proxy\ProxyFactory`
- * `Doctrine\ORM\Proxy\Autoloader` - we suggest using the composer autoloader instead
- 
-These methods have been deprecated:
-
- * `Doctrine\ORM\Configuration#getAutoGenerateProxyClasses()`
- * `Doctrine\ORM\Configuration#getProxyDir()`
- * `Doctrine\ORM\Configuration#getProxyNamespace()`
-
-## Deprecated `Doctrine\ORM\Version`
-
-The `Doctrine\ORM\Version` class is now deprecated and will be removed in Doctrine ORM 3.0:
-please refrain from checking the ORM version at runtime or use
-[ocramius/package-versions](https://github.com/Ocramius/PackageVersions/).
-
-## Deprecated `EntityManager#merge()` and `EntityManager#detach()` methods
-
-Merge and detach semantics were a poor fit for the PHP "share-nothing" architecture.
-In addition to that, merging/detaching caused multiple issues with data integrity
-in the managed entity graph, which was constantly spawning more edge-case bugs/scenarios.
-
-The following API methods were therefore deprecated:
-
-* `EntityManager#merge()`
-* `EntityManager#detach()`
-* `UnitOfWork#merge()`
-* `UnitOfWork#detach()`
-
-Users are encouraged to migrate `EntityManager#detach()` calls to `EntityManager#clear()`.
-
-In order to maintain performance on batch processing jobs, it is endorsed to enable
-the second level cache (http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/second-level-cache.html)
-on entities that are frequently reused across multiple `EntityManager#clear()` calls.
-
-An alternative to `EntityManager#merge()` will not be provided by ORM 3.0, since the merging
-semantics should be part of the business domain rather than the persistence domain of an
-application. If your application relies heavily on CRUD-alike interactions and/or `PATCH`
-restful operations, you should look at alternatives such as [JMSSerializer](https://github.com/schmittjoh/serializer).
-
-## Extending `EntityManager` is deprecated
-
-Final keyword will be added to the `EntityManager::class` in Doctrine ORM 3.0 in order to ensure that EntityManager
- is not used as valid extension point. Valid extension point should be EntityManagerInterface.
-
-## Deprecated `EntityManager#clear($entityName)`
-
-If your code relies on clearing a single entity type via `EntityManager#clear($entityName)`,
-the signature has been changed to `EntityManager#clear()`.
-
-The main reason is that partial clears caused multiple issues with data integrity
-in the managed entity graph, which was constantly spawning more edge-case bugs/scenarios.
-
-## Deprecated `EntityManager#flush($entity)` and `EntityManager#flush($entities)`
-
-If your code relies on single entity flushing optimisations via
-`EntityManager#flush($entity)`, the signature has been changed to
-`EntityManager#flush()`.
-
-Said API was affected by multiple data integrity bugs due to the fact
-that change tracking was being restricted upon a subset of the managed
-entities. The ORM cannot support committing subsets of the managed 
-entities while also guaranteeing data integrity, therefore this
-utility was removed.
-
-The `flush()` semantics will remain the same, but the change tracking will be performed
-on all entities managed by the unit of work, and not just on the provided
-`$entity` or `$entities`, as the parameter is now completely ignored.
-
-The same applies to `UnitOfWork#commit($entity)`, which will simply be
-`UnitOfWork#commit()`.
-
-If you would still like to perform batching operations over small `UnitOfWork`
-instances, it is suggested to follow these paths instead:
-
- * eagerly use `EntityManager#clear()` in conjunction with a specific second level
-   cache configuration (see http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/second-level-cache.html)
- * use an explicit change tracking policy (see http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/change-tracking-policies.html)
-
-## Deprecated `YAML` mapping drivers.
-
-If your code relies on `YamlDriver`  or `SimpleYamlDriver`, you **MUST** change to
-annotation or XML drivers instead.
-
-## Deprecated: `Doctrine\ORM\EntityManagerInterface#copy()`
-
-Method `Doctrine\ORM\EntityManagerInterface#copy()` never got its implementation and is deprecated.
-It will be removed in 3.0.
-
-# Upgrade to 2.6
-
-## Added `Doctrine\ORM\EntityRepository::count()` method
-
-`Doctrine\ORM\EntityRepository::count()` has been added. This new method has different
-signature than `Countable::count()` (required parameter) and therefore are not compatible.
-If your repository implemented the `Countable` interface, you will have to use
-`$repository->count([])` instead and not implement `Countable` interface anymore.
-
-## Minor BC BREAK: `Doctrine\ORM\Tools\Console\ConsoleRunner` is now final
-
-Since it's just an utilitarian class and should not be inherited.
-
-## Minor BC BREAK: removed `Doctrine\ORM\Query\QueryException::associationPathInverseSideNotSupported()`
-
-Method `Doctrine\ORM\Query\QueryException::associationPathInverseSideNotSupported()`
-now has a required parameter `$pathExpr`.
-
-## Minor BC BREAK: removed `Doctrine\ORM\Query\Parser#isInternalFunction()`
-
-Method `Doctrine\ORM\Query\Parser#isInternalFunction()` was removed because
-the distinction between internal function and user defined DQL was removed.
-[#6500](https://github.com/doctrine/orm/pull/6500)
-
-## Minor BC BREAK: removed `Doctrine\ORM\ORMException#overwriteInternalDQLFunctionNotAllowed()`
-
-Method `Doctrine\ORM\Query\Parser#overwriteInternalDQLFunctionNotAllowed()` was
-removed because of the choice to allow users to overwrite internal functions, ie
-`AVG`, `SUM`, `COUNT`, `MIN` and `MAX`. [#6500](https://github.com/doctrine/orm/pull/6500)
-
-## PHP 7.1 is now required
-
-Doctrine 2.6 now requires PHP 7.1 or newer.
-
-As a consequence, automatic cache setup in Doctrine\ORM\Tools\Setup::create*Configuration() was changed:
-- APCu extension (ext-apcu) will now be used instead of abandoned APC (ext-apc).
-- Memcached extension (ext-memcached) will be used instead of obsolete Memcache (ext-memcache).
-- XCache support was dropped as it doesn't work with PHP 7.
-
-# Upgrade to 2.5
-
-## Minor BC BREAK: removed `Doctrine\ORM\Query\SqlWalker#walkCaseExpression()`
-
-Method `Doctrine\ORM\Query\SqlWalker#walkCaseExpression()` was unused and part
-of the internal API of the ORM, so it was removed. [#5600](https://github.com/doctrine/orm/pull/5600).
-
-## Minor BC BREAK: removed $className parameter on `AbstractEntityInheritancePersister#getSelectJoinColumnSQL()`
-
-As `$className` parameter was not used in the method, it was safely removed.
-
-## Minor BC BREAK: query cache key time is now a float
-
-As of 2.5.5, the `QueryCacheEntry#time` property will contain a float value
-instead of an integer in order to have more precision and also to be consistent
-with the `TimestampCacheEntry#time`.
-
-## Minor BC BREAK: discriminator map must now include all non-transient classes
-
-It is now required that you declare the root of an inheritance in the
-discriminator map.
-
-When declaring an inheritance map, it was previously possible to skip the root
-of the inheritance in the discriminator map. This was actually a validation
-mistake by Doctrine2 and led to problems when trying to persist instances of
-that class.
-
-If you don't plan to persist instances some classes in your inheritance, then
-either:
-
- - make those classes `abstract`
- - map those classes as `MappedSuperclass`
-
-## Minor BC BREAK: ``EntityManagerInterface`` instead of ``EntityManager`` in type-hints
- 
-As of 2.5, classes requiring the ``EntityManager`` in any method signature will now require 
-an ``EntityManagerInterface`` instead.
-If you are extending any of the following classes, then you need to check following
-signatures:
-
-- ``Doctrine\ORM\Tools\DebugUnitOfWorkListener#dumpIdentityMap(EntityManagerInterface $em)``
-- ``Doctrine\ORM\Mapping\ClassMetadataFactory#setEntityManager(EntityManagerInterface $em)``
-
-## Minor BC BREAK: Custom Hydrators API change
-
-As of 2.5, `AbstractHydrator` does not enforce the usage of cache as part of
-API, and now provides you a clean API for column information through the method
-`hydrateColumnInfo($column)`.
-Cache variable being passed around by reference is no longer needed since
-Hydrators are per query instantiated since Doctrine 2.4.
-
-## Minor BC BREAK: Entity based ``EntityManager#clear()`` calls follow cascade detach
-
-Whenever ``EntityManager#clear()`` method gets called with a given entity class
-name, until 2.4, it was only detaching the specific requested entity.
-As of 2.5, ``EntityManager`` will follow configured cascades, providing a better
-memory management since associations will be garbage collected, optimizing
-resources consumption on long running jobs.
-
-## BC BREAK: NamingStrategy interface changes
-
-1. A new method ``embeddedFieldToColumnName($propertyName, $embeddedColumnName)``
-
-This method generates the column name for fields of embedded objects. If you implement your custom NamingStrategy, you
-now also need to implement this new method.
-
-2. A change to method ``joinColumnName()`` to include the $className
-
-## Updates on entities scheduled for deletion are no longer processed
-
-In Doctrine 2.4, if you modified properties of an entity scheduled for deletion, UnitOfWork would
-produce an UPDATE statement to be executed right before the DELETE statement. The entity in question
-was therefore present in ``UnitOfWork#entityUpdates``, which means that ``preUpdate`` and ``postUpdate``
-listeners were (quite pointlessly) called. In ``preFlush`` listeners, it used to be possible to undo
-the scheduled deletion for updated entities (by calling ``persist()`` if the entity was found in both
-``entityUpdates`` and ``entityDeletions``). This does not work any longer, because the entire changeset
-calculation logic is optimized away.
-
-## Minor BC BREAK: Default lock mode changed from LockMode::NONE to null in method signatures
-
-A misconception concerning default lock mode values in method signatures lead to unexpected behaviour
-in SQL statements on SQL Server. With a default lock mode of ``LockMode::NONE`` throughout the
-method signatures in ORM, the table lock hint ``WITH (NOLOCK)`` was appended to all locking related
-queries by default. This could result in unpredictable results because an explicit ``WITH (NOLOCK)``
-table hint tells SQL Server to run a specific query in transaction isolation level READ UNCOMMITTED
-instead of the default READ COMMITTED transaction isolation level.
-Therefore there now is a distinction between ``LockMode::NONE`` and ``null`` to be able to tell
-Doctrine whether to add table lock hints to queries by intention or not. To achieve this, the following
-method signatures have been changed to declare ``$lockMode = null`` instead of ``$lockMode = LockMode::NONE``:
-
-- ``Doctrine\ORM\Cache\Persister\AbstractEntityPersister#getSelectSQL()``
-- ``Doctrine\ORM\Cache\Persister\AbstractEntityPersister#load()``
-- ``Doctrine\ORM\Cache\Persister\AbstractEntityPersister#refresh()``
-- ``Doctrine\ORM\Decorator\EntityManagerDecorator#find()``
-- ``Doctrine\ORM\EntityManager#find()``
-- ``Doctrine\ORM\EntityRepository#find()``
-- ``Doctrine\ORM\Persisters\BasicEntityPersister#getSelectSQL()``
-- ``Doctrine\ORM\Persisters\BasicEntityPersister#load()``
-- ``Doctrine\ORM\Persisters\BasicEntityPersister#refresh()``
-- ``Doctrine\ORM\Persisters\EntityPersister#getSelectSQL()``
-- ``Doctrine\ORM\Persisters\EntityPersister#load()``
-- ``Doctrine\ORM\Persisters\EntityPersister#refresh()``
-- ``Doctrine\ORM\Persisters\JoinedSubclassPersister#getSelectSQL()``
-
-You should update signatures for these methods if you have subclassed one of the above classes.
-Please also check the calling code of these methods in your application and update if necessary.
-
-**Note:**
-This in fact is really a minor BC BREAK and should not have any affect on database vendors
-other than SQL Server because it is the only one that supports and therefore cares about
-``LockMode::NONE``. It's really just a FIX for SQL Server environments using ORM.
-
-## Minor BC BREAK: `__clone` method not called anymore when entities are instantiated via metadata API
-
-As of PHP 5.6, instantiation of new entities is deferred to the
-[`doctrine/instantiator`](https://github.com/doctrine/instantiator) library, which will avoid calling `__clone`
-or any public API on instantiated objects.
-
-## BC BREAK: `Doctrine\ORM\Repository\DefaultRepositoryFactory` is now `final`
-
-Please implement the `Doctrine\ORM\Repository\RepositoryFactory` interface instead of extending
-the `Doctrine\ORM\Repository\DefaultRepositoryFactory`.
-
-## BC BREAK: New object expression DQL queries now respects user provided aliasing and not return consumed fields
-
-When executing DQL queries with new object expressions, instead of returning DTOs numerically indexes, it will now respect user provided aliases. Consider the following query:
-
-    SELECT new UserDTO(u.id,u.name) as user,new AddressDTO(a.street,a.postalCode) as address, a.id as addressId FROM User u INNER JOIN u.addresses a WITH a.isPrimary = true
-    
-Previously, your result would be similar to this:
-
-    array(
-        0=>array(
-            0=>{UserDTO object},
-            1=>{AddressDTO object},
-            2=>{u.id scalar},
-            3=>{u.name scalar},
-            4=>{a.street scalar},
-            5=>{a.postalCode scalar},
-            'addressId'=>{a.id scalar},
-        ),
-        ...
-    )
-
-From now on, the resultset will look like this:
-
-    array(
-        0=>array(
-            'user'=>{UserDTO object},
-            'address'=>{AddressDTO object},
-            'addressId'=>{a.id scalar}
-        ),
-        ...
-    )
-
-## Minor BC BREAK: added second parameter $indexBy in EntityRepository#createQueryBuilder method signature
-
-Added way to access the underlying QueryBuilder#from() method's 'indexBy' parameter when using EntityRepository#createQueryBuilder()
-
-# Upgrade to 2.4
-
-## BC BREAK: Compatibility Bugfix in PersistentCollection#matching()
-
-In Doctrine 2.3 it was possible to use the new ``matching($criteria)``
-functionality by adding constraints for assocations based on ID:
-
-    Criteria::expr()->eq('association', $assocation->getId());
-
-This functionality does not work on InMemory collections however, because
-in memory criteria compares object values based on reference.
-As of 2.4 the above code will throw an exception. You need to change
-offending code to pass the ``$assocation`` reference directly:
-
-    Criteria::expr()->eq('association', $assocation);
-
-## Composer is now the default autoloader
-
-The test suite now runs with composer autoloading. Support for PEAR, and tarball autoloading is deprecated.
-Support for GIT submodules is removed.
-
-## OnFlush and PostFlush event always called
-
-Before 2.4 the postFlush and onFlush events were only called when there were
-actually entities that changed. Now these events are called no matter if there
-are entities in the UoW or changes are found.
-
-## Parenthesis are now considered in arithmetic expression
-
-Before 2.4 parenthesis are not considered in arithmetic primary expression.
-That's conceptually wrong, since it might result in wrong values. For example:
-
-The DQL:
-
-    SELECT 100 / ( 2 * 2 ) FROM MyEntity
-
-Before 2.4 it generates the SQL:
-
-    SELECT 100 / 2 * 2 FROM my_entity
-
-Now parenthesis are considered, the previous DQL will generate:
-
-    SELECT 100 / (2 * 2) FROM my_entity
-
 # Upgrade to 2.3
 
-## Auto Discriminator Map breaks userland implementations with Listener
-
-The new feature to detect discriminator maps automatically when none
-are provided breaks userland implementations doing this with a
-listener in ``loadClassMetadata`` event.
-
-## EntityManager#find() not calls EntityRepository#find() anymore
-
-Previous to 2.3, calling ``EntityManager#find()`` would be delegated to
-``EntityRepository#find()``.  This has lead to some unexpected behavior in the
-core of Doctrine when people have overwritten the find method in their
-repositories. That is why this behavior has been reversed in 2.3, and
-``EntityRepository#find()`` calls ``EntityManager#find()`` instead.

-COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
-COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
-AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.

-
-1. Definitions
-
- a. "Adaptation" means a work based upon the Work, or upon the Work and
-    other pre-existing works, such as a translation, adaptation,
-    derivative work, arrangement of music or other alterations of a
-    literary or artistic work, or phonogram or performance and includes
-    cinematographic adaptations or any other form in which the Work may be
-    recast, transformed, or adapted including in any form recognizably
-    derived from the original, except that a work that constitutes a
-    Collection will not be considered an Adaptation for the purpose of
-    this License. For the avoidance of doubt, where the Work is a musical
-    work, performance or phonogram, the synchronization of the Work in
-    timed-relation with a moving image ("synching") will be considered an
-    Adaptation for the purpose of this License.
- b. "Collection" means a collection of literary or artistic works, such as
-    encyclopedias and anthologies, or performances, phonograms or
-    broadcasts, or other works or subject matter other than works listed
-    in Section 1(g) below, which, by reason of the selection and
-    arrangement of their contents, constitute intellectual creations, in
-    which the Work is included in its entirety in unmodified form along
-    with one or more other contributions, each constituting separate and
-    independent works in themselves, which together are assembled into a
-    collective whole. A work that constitutes a Collection will not be
-    considered an Adaptation (as defined above) for the purposes of this
-    License.
- c. "Distribute" means to make available to the public the original and
-    copies of the Work or Adaptation, as appropriate, through sale or
-    other transfer of ownership.
- d. "License Elements" means the following high-level license attributes
-    as selected by Licensor and indicated in the title of this License:
-    Attribution, Noncommercial, ShareAlike.
- e. "Licensor" means the individual, individuals, entity or entities that
-    offer(s) the Work under the terms of this License.
- f. "Original Author" means, in the case of a literary or artistic work,

-    or if no individual or entity can be identified, the publisher; and in
-    addition (i) in the case of a performance the actors, singers,
-    musicians, dancers, and other persons who act, sing, deliver, declaim,
-    play in, interpret or otherwise perform literary or artistic works or
-    expressions of folklore; (ii) in the case of a phonogram the producer
-    being the person or legal entity who first fixes the sounds of a
-    performance or other sounds; and, (iii) in the case of broadcasts, the
-    organization that transmits the broadcast.
- g. "Work" means the literary and/or artistic work offered under the terms
-    of this License including without limitation any production in the
-    literary, scientific and artistic domain, whatever may be the mode or
-    form of its expression including digital form, such as a book,
-    pamphlet and other writing; a lecture, address, sermon or other work
-    of the same nature; a dramatic or dramatico-musical work; a
-    choreographic work or entertainment in dumb show; a musical
-    composition with or without words; a cinematographic work to which are
-    assimilated works expressed by a process analogous to cinematography;
-    a work of drawing, painting, architecture, sculpture, engraving or
-    lithography; a photographic work to which are assimilated works
-    expressed by a process analogous to photography; a work of applied
-    art; an illustration, map, plan, sketch or three-dimensional work
-    relative to geography, topography, architecture or science; a
-    performance; a broadcast; a phonogram; a compilation of data to the
-    extent it is protected as a copyrightable work; or a work performed by
-    a variety or circus performer to the extent it is not otherwise
-    considered a literary or artistic work.
- h. "You" means an individual or entity exercising rights under this
-    License who has not previously violated the terms of this License with
-    respect to the Work, or who has received express permission from the
-    Licensor to exercise rights under this License despite a previous
-    violation.
- i. "Publicly Perform" means to perform public recitations of the Work and
-    to communicate to the public those public recitations, by any means or
-    process, including by wire or wireless means or public digital
-    performances; to make available to the public Works in such a way that
-    members of the public may access these Works from a place and at a
-    place individually chosen by them; to perform the Work to the public
-    by any means or process and the communication to the public of the

-    medium.
-
-2. Fair Dealing Rights. Nothing in this License is intended to reduce,
-limit, or restrict any uses free from copyright or rights arising from
-limitations or exceptions that are provided for in connection with the
-copyright protection under copyright law or other applicable laws.
-
-3. License Grant. Subject to the terms and conditions of this License,
-Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
-perpetual (for the duration of the applicable copyright) license to
-exercise the rights in the Work as stated below:
-
- a. to Reproduce the Work, to incorporate the Work into one or more
-    Collections, and to Reproduce the Work as incorporated in the
-    Collections;
- b. to create and Reproduce Adaptations provided that any such Adaptation,
-    including any translation in any medium, takes reasonable steps to
-    clearly label, demarcate or otherwise identify that changes were made
-    to the original Work. For example, a translation could be marked "The
-    original work was translated from English to Spanish," or a
-    modification could indicate "The original work has been modified.";
- c. to Distribute and Publicly Perform the Work including as incorporated
-    in Collections; and,
- d. to Distribute and Publicly Perform Adaptations.
-
-The above rights may be exercised in all media and formats whether now
-known or hereafter devised. The above rights include the right to make
-such modifications as are technically necessary to exercise the rights in
-other media and formats. Subject to Section 8(f), all rights not expressly
-granted by Licensor are hereby reserved, including but not limited to the
-rights described in Section 4(e).
-
-4. Restrictions. The license granted in Section 3 above is expressly made
-subject to and limited by the following restrictions:
-
- a. You may Distribute or Publicly Perform the Work only under the terms
-    of this License. You must include a copy of, or the Uniform Resource
-    Identifier (URI) for, this License with every copy of the Work You
-    Distribute or Publicly Perform. You may not offer or impose any terms
-    on the Work that restrict the terms of this License or the ability of
-    the recipient of the Work to exercise the rights granted to that
-    recipient under the terms of the License. You may not sublicense the
-    Work. You must keep intact all notices that refer to this License and
-    to the disclaimer of warranties with every copy of the Work You
-    Distribute or Publicly Perform. When You Distribute or Publicly
-    Perform the Work, You may not impose any effective technological
-    measures on the Work that restrict the ability of a recipient of the
-    Work from You to exercise the rights granted to that recipient under
-    the terms of the License. This Section 4(a) applies to the Work as
-    incorporated in a Collection, but this does not require the Collection
-    apart from the Work itself to be made subject to the terms of this
-    License. If You create a Collection, upon notice from any Licensor You
-    must, to the extent practicable, remove from the Collection any credit
-    as required by Section 4(d), as requested. If You create an
-    Adaptation, upon notice from any Licensor You must, to the extent
-    practicable, remove from the Adaptation any credit as required by
-    Section 4(d), as requested.
- b. You may Distribute or Publicly Perform an Adaptation only under: (i)
-    the terms of this License; (ii) a later version of this License with
-    the same License Elements as this License; (iii) a Creative Commons
-    jurisdiction license (either this or a later license version) that
-    contains the same License Elements as this License (e.g.,
-    Attribution-NonCommercial-ShareAlike 3.0 US) ("Applicable License").
-    You must include a copy of, or the URI, for Applicable License with
-    every copy of each Adaptation You Distribute or Publicly Perform. You
-    may not offer or impose any terms on the Adaptation that restrict the
-    terms of the Applicable License or the ability of the recipient of the
-    Adaptation to exercise the rights granted to that recipient under the
-    terms of the Applicable License. You must keep intact all notices that
-    refer to the Applicable License and to the disclaimer of warranties
-    with every copy of the Work as included in the Adaptation You
-    Distribute or Publicly Perform. When You Distribute or Publicly
-    Perform the Adaptation, You may not impose any effective technological
-    measures on the Adaptation that restrict the ability of a recipient of
-    the Adaptation from You to exercise the rights granted to that
-    recipient under the terms of the Applicable License. This Section 4(b)
-    applies to the Adaptation as incorporated in a Collection, but this
-    does not require the Collection apart from the Adaptation itself to be
-    made subject to the terms of the Applicable License.
- c. You may not exercise any of the rights granted to You in Section 3
-    above in any manner that is primarily intended for or directed toward
-    commercial advantage or private monetary compensation. The exchange of
-    the Work for other copyrighted works by means of digital file-sharing
-    or otherwise shall not be considered to be intended for or directed
-    toward commercial advantage or private monetary compensation, provided
-    there is no payment of any monetary compensation in con-nection with
-    the exchange of copyrighted works.
- d. If You Distribute, or Publicly Perform the Work or any Adaptations or
-    Collections, You must, unless a request has been made pursuant to
-    Section 4(a), keep intact all copyright notices for the Work and
-    provide, reasonable to the medium or means You are utilizing: (i) the
-    name of the Original Author (or pseudonym, if applicable) if supplied,
-    and/or if the Original Author and/or Licensor designate another party
-    or parties (e.g., a sponsor institute, publishing entity, journal) for
-    attribution ("Attribution Parties") in Licensor's copyright notice,
-    terms of service or by other reasonable means, the name of such party
-    or parties; (ii) the title of the Work if supplied; (iii) to the
-    extent reasonably practicable, the URI, if any, that Licensor
-    specifies to be associated with the Work, unless such URI does not
-    refer to the copyright notice or licensing information for the Work;
-    and, (iv) consistent with Section 3(b), in the case of an Adaptation,
-    a credit identifying the use of the Work in the Adaptation (e.g.,
-    "French translation of the Work by Original Author," or "Screenplay
-    based on original Work by Original Author"). The credit required by
-    this Section 4(d) may be implemented in any reasonable manner;
-    provided, however, that in the case of a Adaptation or Collection, at
-    a minimum such credit will appear, if a credit for all contributing
-    authors of the Adaptation or Collection appears, then as part of these
-    credits and in a manner at least as prominent as the credits for the
-    other contributing authors. For the avoidance of doubt, You may only
-    use the credit required by this Section for the purpose of attribution
-    in the manner set out above and, by exercising Your rights under this
-    License, You may not implicitly or explicitly assert or imply any
-    connection with, sponsorship or endorsement by the Original Author,
-    Licensor and/or Attribution Parties, as appropriate, of You or Your
-    use of the Work, without the separate, express prior written
-    permission of the Original Author, Licensor and/or Attribution
-    Parties.
- e. For the avoidance of doubt:
-
-     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme cannot be waived, the Licensor
-        reserves the exclusive right to collect such royalties for any
-        exercise by You of the rights granted under this License;
-    ii. Waivable Compulsory License Schemes. In those jurisdictions in
-        which the right to collect royalties through any statutory or
-        compulsory licensing scheme can be waived, the Licensor reserves
-        the exclusive right to collect such royalties for any exercise by
-        You of the rights granted under this License if Your exercise of
-        such rights is for a purpose or use which is otherwise than
-        noncommercial as permitted under Section 4(c) and otherwise waives
-        the right to collect royalties through any statutory or compulsory
-        licensing scheme; and,
-   iii. Voluntary License Schemes. The Licensor reserves the right to
-        collect royalties, whether individually or, in the event that the
-        Licensor is a member of a collecting society that administers
-        voluntary licensing schemes, via that society, from any exercise
-        by You of the rights granted under this License that is for a
-        purpose or use which is otherwise than noncommercial as permitted
-        under Section 4(c).
- f. Except as otherwise agreed in writing by the Licensor or as may be
-    otherwise permitted by applicable law, if You Reproduce, Distribute or
-    Publicly Perform the Work either by itself or as part of any
-    Adaptations or Collections, You must not distort, mutilate, modify or
-    take other derogatory action in relation to the Work which would be
-    prejudicial to the Original Author's honor or reputation. Licensor
-    agrees that in those jurisdictions (e.g. Japan), in which any exercise
-    of the right granted in Section 3(b) of this License (the right to
-    make Adaptations) would be deemed to be a distortion, mutilation,
-    modification or other derogatory action prejudicial to the Original
-    Author's honor and reputation, the Licensor will waive or not assert,
-    as appropriate, this Section, to the fullest extent permitted by the
-    applicable national law, to enable You to reasonably exercise Your
-    right under Section 3(b) of this License (right to make Adaptations)
-    but not otherwise.
-
-5. Representations, Warranties and Disclaimer
-
-UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING AND TO THE
-FULLEST EXTENT PERMITTED BY APPLICABLE LAW, LICENSOR OFFERS THE WORK AS-IS
-AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE
-WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING, WITHOUT
-LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
-PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER DEFECTS,
-ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT
-DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED
-WARRANTIES, SO THIS EXCLUSION MAY NOT APPLY TO YOU.
-
-6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
-LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
-ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
-ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
-BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
-7. Termination
-
- a. This License and the rights granted hereunder will terminate
-    automatically upon any breach by You of the terms of this License.
-    Individuals or entities who have received Adaptations or Collections
-    from You under this License, however, will not have their licenses
-    terminated provided such individuals or entities remain in full
-    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
-    survive any termination of this License.
- b. Subject to the above terms and conditions, the license granted here is
-    perpetual (for the duration of the applicable copyright in the Work).
-    Notwithstanding the above, Licensor reserves the right to release the
-    Work under different license terms or to stop distributing the Work at
-    any time; provided, however that any such election will not serve to
-    withdraw this License (or any other license that has been, or is
-    required to be, granted under the terms of this License), and this
-    License will continue in full force and effect unless terminated as
-    stated above.
-
-8. Miscellaneous
-
- a. Each time You Distribute or Publicly Perform the Work or a Collection,
-    the Licensor offers to the recipient a license to the Work on the same
-    terms and conditions as the license granted to You under this License.
- b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
-    offers to the recipient a license to the original Work on the same
-    terms and conditions as the license granted to You under this License.
- c. If any provision of this License is invalid or unenforceable under
-    applicable law, it shall not affect the validity or enforceability of
-    the remainder of the terms of this License, and without further action
-    by the parties to this agreement, such provision shall be reformed to
-    the minimum extent necessary to make such provision valid and
-    enforceable.
- d. No term or provision of this License shall be deemed waived and no
-    breach consented to unless such waiver or consent shall be in writing
-    and signed by the party to be charged with such waiver or consent.
- e. This License constitutes the entire agreement between the parties with
-    respect to the Work licensed here. There are no understandings,
-    agreements or representations with respect to the Work not specified
-    here. Licensor shall not be bound by any additional provisions that
-    may appear in any communication from You. This License may not be
-    modified without the mutual written agreement of the Licensor and You.
- f. The rights granted under, and the subject matter referenced, in this
-    License were drafted utilizing the terminology of the Berne Convention
-    for the Protection of Literary and Artistic Works (as amended on
-    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
-    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
-    and the Universal Copyright Convention (as revised on July 24, 1971).
-    These rights and subject matter take effect in the relevant
-    jurisdiction in which the License terms are sought to be enforced
-    according to the corresponding provisions of the implementation of
-    those treaty provisions in the applicable national law. If the
-    standard suite of rights granted under applicable copyright law
-    includes additional rights not granted under this License, such
-    additional rights are deemed to be included in the License; this
-    License is not intended to restrict the license of any rights under
-    applicable law.

-Advanced field value conversion using custom mapping types
-==========================================================
-
-.. sectionauthor:: Jan Sorgalla <jsorgalla@googlemail.com>
-
-When creating entities, you sometimes have the need to transform field values
-before they are saved to the database. In Doctrine you can use Custom Mapping 
-Types to solve this (see: :ref:`reference-basic-mapping-custom-mapping-types`).
-
-There are several ways to achieve this: converting the value inside the Type
-class, converting the value on the database-level or a combination of both.
-
-This article describes the third way by implementing the MySQL specific column
-type `Point <https://dev.mysql.com/doc/refman/8.0/en/gis-class-point.html>`_.
-
-The ``Point`` type is part of the `Spatial extension <https://dev.mysql.com/doc/refman/8.0/en/spatial-extensions.html>`_
-of MySQL and enables you to store a single location in a coordinate space by
-using x and y coordinates. You can use the Point type to store a 
-longitude/latitude pair to represent a geographic location.
-
-The entity
-----------
-
-We create a simple entity with a field ``$point`` which holds a value object
-``Point`` representing the latitude and longitude of the position.
-
-The entity class:
-
-.. code-block:: php
-
-    <?php
-    
-    namespace Geo\Entity;
- 
-    /**
-     * @Entity
-     */
-    class Location
-    {
-        /**
-         * @Column(type="point")
-         *
-         * @var \Geo\ValueObject\Point
-         */
-        private $point;
-
-        /**
-         * @Column(type="string")
-         *
-         * @var string
-         */
-        private $address;
-
-        /**
-         * @param \Geo\ValueObject\Point $point
-         */
-        public function setPoint(\Geo\ValueObject\Point $point)
-        {
-            $this->point = $point;
-        }
-
-        /**
-         * @return \Geo\ValueObject\Point
-         */
-        public function getPoint()
-        {
-            return $this->point;
-        }
-
-        /**
-         * @param string $address
-         */
-        public function setAddress($address)
-        {
-            $this->address = $address;
-        }
-
-        /**
-         * @return string
-         */
-        public function getAddress()
-        {
-            return $this->address;
-        }
-    }
-
-We use the custom type ``point`` in the ``@Column``  docblock annotation of the 
-``$point`` field. We will create this custom mapping type in the next chapter.
-
-The point class:
-
-.. code-block:: php
-
-    <?php
-    
-    namespace Geo\ValueObject;
-
-    class Point
-    {
-
-        /**
-         * @param float $latitude
-         * @param float $longitude
-         */
-        public function __construct($latitude, $longitude)
-        {
-            $this->latitude  = $latitude;
-            $this->longitude = $longitude;
-        }
-
-        /**
-         * @return float
-         */
-        public function getLatitude()
-        {
-            return $this->latitude;
-        }
-
-        /**
-         * @return float
-         */
-        public function getLongitude()
-        {
-            return $this->longitude;
-        }
-    }
-
-The mapping type
-----------------
-
-Now we're going to create the ``point`` type and implement all required methods.
-
-.. code-block:: php
-
-    <?php
-
-    namespace Geo\Types;
-
-    use Doctrine\DBAL\Types\Type;
-    use Doctrine\DBAL\Platforms\AbstractPlatform;
-
-    use Geo\ValueObject\Point;
-
-    class PointType extends Type
-    {
-        const POINT = 'point';
-
-        public function getName()
-        {
-            return self::POINT;
-        }
-
-        public function getSQLDeclaration(array $fieldDeclaration, AbstractPlatform $platform)
-        {
-            return 'POINT';
-        }
-
-        public function convertToPHPValue($value, AbstractPlatform $platform)
-        {
-            list($longitude, $latitude) = sscanf($value, 'POINT(%f %f)');
-
-            return new Point($latitude, $longitude);
-        }
-
-        public function convertToDatabaseValue($value, AbstractPlatform $platform)
-        {
-            if ($value instanceof Point) {
-                $value = sprintf('POINT(%F %F)', $value->getLongitude(), $value->getLatitude());
-            }
-
-            return $value;
-        }
-
-        public function canRequireSQLConversion()
-        {
-            return true;
-        }
-
-        public function convertToPHPValueSQL($sqlExpr, AbstractPlatform $platform)
-        {
-            return sprintf('AsText(%s)', $sqlExpr);
-        }
-
-        public function convertToDatabaseValueSQL($sqlExpr, AbstractPlatform $platform)
-        {
-            return sprintf('PointFromText(%s)', $sqlExpr);
-        }
-    }
-
-We do a 2-step conversion here. In the first step, we convert the ``Point``
-object into a string representation before saving to the database (in the
-``convertToDatabaseValue`` method) and back into an object after fetching the
-value from the database (in the ``convertToPHPValue`` method).
-
-The format of the string representation format is called
-`Well-known text (WKT) <http://en.wikipedia.org/wiki/Well-known_text>`_.
-The advantage of this format is, that it is both human readable and parsable by MySQL.
-
-Internally, MySQL stores geometry values in a binary format that is not 
-identical to the WKT format. So, we need to let MySQL transform the WKT
-representation into its internal format.
-
-This is where the ``convertToPHPValueSQL`` and  ``convertToDatabaseValueSQL``
-methods come into play.
-
-This methods wrap a sql expression (the WKT representation of the Point) into
-MySQL functions `ST_PointFromText <https://dev.mysql.com/doc/refman/8.0/en/gis-wkt-functions.html#function_st-pointfromtext>`_
-and `ST_AsText <https://dev.mysql.com/doc/refman/8.0/en/gis-format-conversion-functions.html#function_st-astext>`_
-which convert WKT strings to and from the internal format of MySQL.
-
-.. note::
-
-    When using DQL queries, the ``convertToPHPValueSQL`` and  
-    ``convertToDatabaseValueSQL`` methods only apply to identification variables
-    and path expressions in SELECT clauses. Expressions in  WHERE clauses are 
-    **not** wrapped!
-
-    If you want to use Point values in WHERE clauses, you have to implement a
-    :doc:`user defined function <dql-user-defined-functions>` for 
-    ``PointFromText``.
-
-Example usage
--------------
-
-.. code-block:: php
-
-    <?php
-
-    // Bootstrapping stuff...
-    // $em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);
-
-    // Setup custom mapping type
-    use Doctrine\DBAL\Types\Type;
-
-    Type::addType('point', 'Geo\Types\PointType');
-    $em->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('point', 'point');
-
-    // Store a Location object
-    use Geo\Entity\Location;
-    use Geo\ValueObject\Point;
-
-    $location = new Location();
-
-    $location->setAddress('1600 Amphitheatre Parkway, Mountain View, CA');
-    $location->setPoint(new Point(37.4220761, -122.0845187));
-
-    $em->persist($location);
-    $em->flush();
-    $em->clear();
-
-    // Fetch the Location object
-    $query = $em->createQuery("SELECT l FROM Geo\Entity\Location l WHERE l.address = '1600 Amphitheatre Parkway, Mountain View, CA'");
-    $location = $query->getSingleResult();
-
-    /* @var Geo\ValueObject\Point */
-    $point = $location->getPoint();

-Aggregate Fields
-================
-
-.. sectionauthor:: Benjamin Eberlei <kontakt@beberlei.de>
-
-You will often come across the requirement to display aggregate
-values of data that can be computed by using the MIN, MAX, COUNT or
-SUM SQL functions. For any ORM this is a tricky issue
-traditionally. Doctrine ORM offers several ways to get access to
-these values and this article will describe all of them from
-different perspectives.
-
-You will see that aggregate fields can become very explicit
-features in your domain model and how this potentially complex
-business rules can be easily tested.
-
-An example model
-----------------
-
-Say you want to model a bank account and all their entries. Entries
-into the account can either be of positive or negative money
-values. Each account has a credit limit and the account is never
-allowed to have a balance below that value.
-
-For simplicity we live in a world where money is composed of
-integers only. Also we omit the receiver/sender name, stated reason
-for transfer and the execution date. These all would have to be
-added on the ``Entry`` object.
-
-Our entities look like:
-
-.. code-block:: php
-
-    <?php
-
-    namespace Bank\Entities;

-         * @ORM\GeneratedValue
-         * @ORM\Column(type="integer")
-         */
-        private ?int $id;
-    
-        /**
-         * @ORM\Column(type="string", unique=true)
-         */
-        private string $no;
-    
-        /**
-         * @ORM\OneToMany(targetEntity="Entry", mappedBy="account", cascade={"persist"})
-         */
-        private array $entries;
-    
-        /**
-         * @ORM\Column(type="integer")
-         */
-        private int $maxCredit = 0;
-    
-        public function __construct(string $no, int $maxCredit = 0)
-        {

-     */

-    {
-        /**

-         * @ORM\Column(type="integer")

-    
-        /**
-         * @ORM\ManyToOne(targetEntity="Account", inversedBy="entries")
-         */
-        private Account $account;
-    
-        /**
-         * @ORM\Column(type="integer")
-         */
-        private int $amount;
-    
-        public function __construct(Account $account, int $amount)
-        {
-            $this->account = $account;
-            $this->amount = $amount;

-Using DQL
----------
-
-The Doctrine Query Language allows you to select for aggregate
-values computed from fields of your Domain Model. You can select
-the current balance of your account by calling:

-    $dql = "SELECT SUM(e.amount) AS balance FROM Bank\Entities\Entry e " .
-           "WHERE e.account = ?1";
-    $balance = $em->createQuery($dql)
-                  ->setParameter(1, $myAccountId)
-                  ->getSingleScalarResult();
-
-The ``$em`` variable in this (and forthcoming) example holds the
-Doctrine ``EntityManager``. We create a query for the SUM of all
-amounts (negative amounts are withdraws) and retrieve them as a
-single scalar result, essentially return only the first column of
-the first row.
-
-This approach is simple and powerful, however it has a serious
-drawback. We have to execute a specific query for the balance
-whenever we need it.
-
-To implement a powerful domain model we would rather have access to
-the balance from our ``Account`` entity during all times (even if
-the Account was not persisted in the database before!).
-
-Also an additional requirement is the max credit per ``Account``
-rule.
-
-We cannot reliably enforce this rule in our ``Account`` entity with
-the DQL retrieval of the balance. There are many different ways to
-retrieve accounts. We cannot guarantee that we can execute the
-aggregation query for all these use-cases, let alone that a
-userland programmer checks this balance against newly added
-entries.
-
-Using your Domain Model
------------------------
-
-``Account`` and all the ``Entry`` instances are connected through a
-collection, which means we can compute this value at runtime:
-
-.. code-block:: php
-
-    <?php
-    class Account
-    {
-        // .. previous code
-
-        public function getBalance(): int
-        {
-            $balance = 0;
-            foreach ($this->entries as $entry) {
-                $balance += $entry->getAmount();
-            }
-
-            return $balance;
-        }
-    }
-
-Now we can always call ``Account::getBalance()`` to access the
-current account balance.
-
-To enforce the max credit rule we have to implement the "Aggregate
-Root" pattern as described in Eric Evans book on Domain Driven
-Design. Described with one sentence, an aggregate root controls the
-instance creation, access and manipulation of its children.
-
-In our case we want to enforce that new entries can only added to
-the ``Account`` by using a designated method. The ``Account`` is
-the aggregate root of this relation. We can also enforce the
-correctness of the bi-directional ``Account`` <-> ``Entry``
-relation with this method:
-
-.. code-block:: php
-
-    <?php
-    class Account
-    {
-        public function addEntry(int $amount): void
-        {
-            $this->assertAcceptEntryAllowed($amount);
-    
-            $e = new Entry($this, $amount);
-            $this->entries[] = $e;
-        }
-    }
-
-Now look at the following test-code for our entities:
-
-.. code-block:: php
-
-    <?php
-
-    use PHPUnit\Framework\TestCase;
-
-    class AccountTest extends TestCase
-    {
-        public function testAddEntry()
-        {
-            $account = new Account("123456", $maxCredit = 200);
-            $this->assertEquals(0, $account->getBalance());
-    
-            $account->addEntry(500);
-            $this->assertEquals(500, $account->getBalance());
-    
-            $account->addEntry(-700);
-            $this->assertEquals(-200, $account->getBalance());
-        }
-    
-        public function testExceedMaxLimit()
-        {
-            $account = new Account("123456", $maxCredit = 200);
-    
-            $this->expectException(Exception::class);
-            $account->addEntry(-1000);
-        }
-    }
-
-To enforce our rule we can now implement the assertion in
-``Account::addEntry``:
-
-.. code-block:: php
-
-    <?php
-
-    class Account
-    {
-        // .. previous code
-
-        private function assertAcceptEntryAllowed(int $amount): void
-        {
-            $futureBalance = $this->getBalance() + $amount;
-            $allowedMinimalBalance = ($this->maxCredit * -1);
-            if ($futureBalance < $allowedMinimalBalance) {
-                throw new Exception("Credit Limit exceeded, entry is not allowed!");
-            }
-        }
-    }
-
-We haven't talked to the entity manager for persistence of our
-account example before. You can call
-``EntityManager::persist($account)`` and then
-``EntityManager::flush()`` at any point to save the account to the
-database. All the nested ``Entry`` objects are automatically
-flushed to the database also.
-
-.. code-block:: php
-
-    <?php
-    $account = new Account("123456", 200);
-    $account->addEntry(500);
-    $account->addEntry(-200);
-    $em->persist($account);
-    $em->flush();
-
-The current implementation has a considerable drawback. To get the
-balance, we have to initialize the complete ``Account::$entries``
-collection, possibly a very large one. This can considerably hurt
-the performance of your application.
-
-Using an Aggregate Field
-------------------------
-
-To overcome the previously mentioned issue (initializing the whole
-entries collection) we want to add an aggregate field called
-"balance" on the Account and adjust the code in
-``Account::getBalance()`` and ``Account:addEntry()``:
-
-.. code-block:: php
-
-    <?php
-    class Account
-    {
-        /**
-         * @ORM\Column(type="integer")
-         */
-        private int $balance = 0;
-    
-        public function getBalance(): int
-        {
-            return $this->balance;
-        }
-    
-        public function addEntry(int $amount): void
-        {
-            $this->assertAcceptEntryAllowed($amount);
-    
-            $e = new Entry($this, $amount);
-            $this->entries[] = $e;
-            $this->balance += $amount;
-        }
-    }
-
-This is a very simple change, but all the tests still pass. Our
-account entities return the correct balance. Now calling the
-``Account::getBalance()`` method will not occur the overhead of
-loading all entries anymore. Adding a new Entry to the
-``Account::$entities`` will also not initialize the collection
-internally.
-
-Adding a new entry is therefore very performant and explicitly
-hooked into the domain model. It will only update the account with
-the current balance and insert the new entry into the database.
-
-Tackling Race Conditions with Aggregate Fields
-----------------------------------------------
-
-Whenever you denormalize your database schema race-conditions can
-potentially lead to inconsistent state. See this example:
-
-.. code-block:: php
-
-    <?php
-
-    use Bank\Entities\Account;
-
-    // The Account $accId has a balance of 0 and a max credit limit of 200:
-    // request 1 account
-    $account1 = $em->find(Account::class, $accId);
-    
-    // request 2 account
-    $account2 = $em->find(Account::class, $accId);
-    
-    $account1->addEntry(-200);
-    $account2->addEntry(-200);
-    
-    // now request 1 and 2 both flush the changes.
-
-The aggregate field ``Account::$balance`` is now -200, however the
-SUM over all entries amounts yields -400. A violation of our max
-credit rule.
-
-You can use both optimistic or pessimistic locking to safe-guard
-your aggregate fields against this kind of race-conditions. Reading
-Eric Evans DDD carefully he mentions that the "Aggregate Root"
-(Account in our example) needs a locking mechanism.
-
-Optimistic locking is as easy as adding a version column:
-
-.. code-block:: php
-
-    <?php
-
-    class Account
-    {
-        /**
-         * @ORM\Column(type="integer")
-         * @ORM\Version
-         */
-        private int $version;
-    }
-
-The previous example would then throw an exception in the face of
-whatever request saves the entity last (and would create the
-inconsistent state).
-
-Pessimistic locking requires an additional flag set on the
-``EntityManager::find()`` call, enabling write locking directly in
-the database using a FOR UPDATE.
-
-.. code-block:: php
-
-    <?php
-
-    use Bank\Entities\Account;
-    use Doctrine\DBAL\LockMode;
-
-    $account = $em->find(Account::class, $accId, LockMode::PESSIMISTIC_READ);
-
-Keeping Updates and Deletes in Sync
------------------------------------
-
-The example shown in this article does not allow changes to the
-value in ``Entry``, which considerably simplifies the effort to
-keep ``Account::$balance`` in sync. If your use-case allows fields
-to be updated or related entities to be removed you have to
-encapsulate this logic in your "Aggregate Root" entity and adjust
-the aggregate field accordingly.
-
-Conclusion
-----------
-
-This article described how to obtain aggregate values using DQL or
-your domain model. It showed how you can easily add an aggregate
-field that offers serious performance benefits over iterating all
-the related objects that make up an aggregate value. Finally I
-showed how you can ensure that your aggregate fields do not get out
-of sync due to race-conditions and concurrent access.

-Custom Mapping Types
-====================
-
-Doctrine allows you to create new mapping types. This can come in
-handy when you're missing a specific mapping type or when you want
-to replace the existing implementation of a mapping type.
-
-In order to create a new mapping type you need to subclass
-``Doctrine\DBAL\Types\Type`` and implement/override the methods as
-you wish. Here is an example skeleton of such a custom type class:
-
-.. code-block:: php
-
-    <?php
-    namespace My\Project\Types;
-
-    use Doctrine\DBAL\Types\Type;
-    use Doctrine\DBAL\Platforms\AbstractPlatform;
-
-    /**
-     * My custom datatype.
-     */
-    class MyType extends Type
-    {
-        const MYTYPE = 'mytype'; // modify to match your type name
-
-        public function getSQLDeclaration(array $fieldDeclaration, AbstractPlatform $platform)
-        {
-            // return the SQL used to create your column type. To create a portable column type, use the $platform.
-        }
-
-        public function convertToPHPValue($value, AbstractPlatform $platform)
-        {
-            // This is executed when the value is read from the database. Make your conversions here, optionally using the $platform.
-        }
-
-        public function convertToDatabaseValue($value, AbstractPlatform $platform)
-        {
-            // This is executed when the value is written to the database. Make your conversions here, optionally using the $platform.
-        }
-
-        public function getName()
-        {
-            return self::MYTYPE; // modify to match your constant name
-        }
-    }
-
-.. note::
-
-    The following assumptions are applied to mapping types by the ORM:
-
-    -  The ``UnitOfWork`` never passes values to the database convert
-       method that did not change in the request.
-    -  The ``UnitOfWork`` internally assumes that entity identifiers are
-       castable to string. Hence, when using custom types that map to PHP
-       objects as IDs, such objects must implement the ``__toString()`` magic
-       method.
-
-When you have implemented the type you still need to let Doctrine
-know about it. This can be achieved through the
-``Doctrine\DBAL\Types\Type#addType($name, $className)``
-method. See the following example:
-
-.. code-block:: php
-
-    <?php
-    // in bootstrapping code
-
-    // ...
-
-    use Doctrine\DBAL\Types\Type;
-
-    // ...
-
-    // Register my type
-    Type::addType('mytype', 'My\Project\Types\MyType');
-
-To convert the underlying database type of your
-new "mytype" directly into an instance of ``MyType`` when performing
-schema operations, the type has to be registered with the database
-platform as well:
-
-.. code-block:: php
-
-    <?php
-    $conn = $em->getConnection();
-    $conn->getDatabasePlatform()->registerDoctrineTypeMapping('db_mytype', 'mytype');
-
-When registering the custom types in the configuration you specify a unique
-name for the mapping type and map that to the corresponding fully qualified
-class name. Now the new type can be used when mapping columns:
-
-.. code-block:: php
-
-    <?php
-    class MyPersistentClass
-    {
-        /** @Column(type="mytype") */
-        private $field;
-    }

-Persisting the Decorator Pattern
-================================
-
-.. sectionauthor:: Chris Woodford <chris.woodford@gmail.com>
-
-This recipe will show you a simple example of how you can use
-Doctrine ORM to persist an implementation of the
-`Decorator Pattern <http://en.wikipedia.org/wiki/Decorator_pattern>`_
-
-Component
----------
-
-The ``Component`` class needs to be persisted, so it's going to
-be an ``Entity``. As the top of the inheritance hierarchy, it's going
-to have to define the persistent inheritance. For this example, we
-will use Single Table Inheritance, but Class Table Inheritance
-would work as well. In the discriminator map, we will define two
-concrete subclasses, ``ConcreteComponent`` and ``ConcreteDecorator``.
-
-.. code-block:: php
-
-    <?php
-
-    namespace Test;
-
-    /**
-     * @Entity
-     * @InheritanceType("SINGLE_TABLE")
-     * @DiscriminatorColumn(name="discr", type="string")
-     * @DiscriminatorMap({"cc" = "Test\Component\ConcreteComponent",
-        "cd" = "Test\Decorator\ConcreteDecorator"})
-     */
-    abstract class Component
-    {
-
-        /**
-         * @Id @Column(type="integer")
-         * @GeneratedValue(strategy="AUTO")
-         */
-        protected $id;
-
-        /** @Column(type="string", nullable=true) */
-        protected $name;
-
-        /**
-         * Get id
-         * @return integer $id
-         */
-        public function getId()
-        {
-            return $this->id;
-        }
-
-        /**
-         * Set name
-         * @param string $name
-         */
-        public function setName($name)
-        {
-            $this->name = $name;
-        }
-
-        /**
-         * Get name
-         * @return string $name
-         */
-        public function getName()
-        {
-            return $this->name;
-        }
-
-    }
-
-ConcreteComponent
------------------
-
-The ``ConcreteComponent`` class is pretty simple and doesn't do much
-more than extend the abstract ``Component`` class (only for the
-purpose of keeping this example simple).
-
-.. code-block:: php
-
-    <?php
-
-    namespace Test\Component;
-
-    use Test\Component;
-
-    /** @Entity */
-    class ConcreteComponent extends Component
-    {}
-
-Decorator
----------
-
-The ``Decorator`` class doesn't need to be persisted, but it does
-need to define an association with a persisted ``Entity``. We can
-use a ``MappedSuperclass`` for this.
-
-.. code-block:: php
-
-    <?php
-
-    namespace Test;
-
-    /** @MappedSuperclass */
-    abstract class Decorator extends Component
-    {
-
-        /**
-         * @OneToOne(targetEntity="Test\Component", cascade={"all"})
-         * @JoinColumn(name="decorates", referencedColumnName="id")
-         */
-        protected $decorates;
-
-        /**
-         * initialize the decorator
-         * @param Component $c
-         */
-        public function __construct(Component $c)
-        {
-            $this->setDecorates($c);
-        }
-
-        /**
-         * (non-PHPdoc)
-         * @see Test.Component::getName()
-         */
-        public function getName()
-        {
-    	    return 'Decorated ' . $this->getDecorates()->getName();
-        }
-
-        /**
-         * the component being decorated
-         * @return Component
-         */
-        protected function getDecorates()
-        {
-    	    return $this->decorates;
-        }
-
-        /**
-         * sets the component being decorated
-         * @param Component $c
-         */
-        protected function setDecorates(Component $c)
-        {
-    	    $this->decorates = $c;
-        }
-
-    }
-
-All operations on the ``Decorator`` (i.e. persist, remove, etc) will
-cascade from the ``Decorator`` to the ``Component``. This means that
-when we persist a ``Decorator``, Doctrine will take care of
-persisting the chain of decorated objects for us. A ``Decorator`` can
-be treated exactly as a ``Component`` when it comes time to
-persisting it.
-
-The ``Decorator's`` constructor accepts an instance of a
-``Component``, as defined by the ``Decorator`` pattern. The
-setDecorates/getDecorates methods have been defined as protected to
-hide the fact that a ``Decorator`` is decorating a ``Component`` and
-keeps the ``Component`` interface and the ``Decorator`` interface
-identical.
-
-To illustrate the intended result of the ``Decorator`` pattern, the
-getName() method has been overridden to append a string to the
-``Component's`` getName() method.
-
-ConcreteDecorator
------------------
-
-The final class required to complete a simple implementation of the
-Decorator pattern is the ``ConcreteDecorator``. In order to further
-illustrate how the ``Decorator`` can alter data as it moves through
-the chain of decoration, a new field, "special", has been added to
-this class. The getName() has been overridden and appends the value
-of the getSpecial() method to its return value.
-
-.. code-block:: php
-
-    <?php
-
-    namespace Test\Decorator;
-
-    use Test\Decorator;
-
-    /** @Entity */
-    class ConcreteDecorator extends Decorator
-    {
-
-        /** @Column(type="string", nullable=true) */
-        protected $special;
-
-        /**
-         * Set special
-         * @param string $special
-         */
-        public function setSpecial($special)
-        {
-            $this->special = $special;
-        }
-
-        /**
-         * Get special
-         * @return string $special
-         */
-        public function getSpecial()
-        {
-            return $this->special;
-        }
-
-        /**
-         * (non-PHPdoc)
-         * @see Test.Component::getName()
-         */
-        public function getName()
-        {
-            return '[' . $this->getSpecial()
-                . '] ' . parent::getName();
-        }
-
-    }
-
-Examples

-    use Test\Component\ConcreteComponent,
-        Test\Decorator\ConcreteDecorator;

-    // create a new concrete component
-    $c = new ConcreteComponent();
-    $c->setName('Test Component 1');
-    $em->persist($c); // assigned unique ID = 1
-
-    // create a new concrete decorator
-    $c = new ConcreteComponent();
-    $c->setName('Test Component 2');
-
-    $d = new ConcreteDecorator($c);
-    $d->setSpecial('Really');
-    $em->persist($d);
-    // assigns c as unique ID = 2, and d as unique ID = 3
-
-    $em->flush();
-
-    $c = $em->find('Test\Component', 1);
-    $d = $em->find('Test\Component', 3);
-
-    echo get_class($c);
-    // prints: Test\Component\ConcreteComponent
-
-    echo $c->getName();
-    // prints: Test Component 1
-
-    echo get_class($d)
-    // prints: Test\Component\ConcreteDecorator
-
-    echo $d->getName();
-    // prints: [Really] Decorated Test Component 2

-Extending DQL in Doctrine ORM: Custom AST Walkers
-===============================================
-
-.. sectionauthor:: Benjamin Eberlei <kontakt@beberlei.de>
-
-The Doctrine Query Language (DQL) is a proprietary sql-dialect that
-substitutes tables and columns for Entity names and their fields.
-Using DQL you write a query against the database using your
-entities. With the help of the metadata you can write very concise,
-compact and powerful queries that are then translated into SQL by
-the Doctrine ORM.
-
-In Doctrine 1 the DQL language was not implemented using a real
-parser. This made modifications of the DQL by the user impossible.
-Doctrine ORM in contrast has a real parser for the DQL language,
-which transforms the DQL statement into an
-`Abstract Syntax Tree <http://en.wikipedia.org/wiki/Abstract_syntax_tree>`_
-and generates the appropriate SQL statement for it. Since this
-process is deterministic Doctrine heavily caches the SQL that is
-generated from any given DQL query, which reduces the performance
-overhead of the parsing process to zero.
-
-You can modify the Abstract syntax tree by hooking into DQL parsing
-process by adding a Custom Tree Walker. A walker is an interface
-that walks each node of the Abstract syntax tree, thereby
-generating the SQL statement.
-
-There are two types of custom tree walkers that you can hook into
-the DQL parser:
-
-
--  An output walker. This one actually generates the SQL, and there
-   is only ever one of them. We implemented the default SqlWalker
-   implementation for it.
--  A tree walker. There can be many tree walkers, they cannot
-   generate the sql, however they can modify the AST before its
-   rendered to sql.
-
-Now this is all awfully technical, so let me come to some use-cases
-fast to keep you motivated. Using walker implementation you can for
-example:
-
-

-
-In this cookbook-entry I will show examples on the first two
-points. There are probably much more use-cases.
-
-Generic count query for pagination
-----------------------------------
-
-Say you have a blog and posts all with one category and one author.
-A query for the front-page or any archive page might look something
-like:
-
-.. code-block:: sql
-
-    SELECT p, c, a FROM BlogPost p JOIN p.category c JOIN p.author a WHERE ...
-
-Now in this query the blog post is the root entity, meaning its the
-one that is hydrated directly from the query and returned as an
-array of blog posts. In contrast the comment and author are loaded
-for deeper use in the object tree.
-
-A pagination for this query would want to approximate the number of
-posts that match the WHERE clause of this query to be able to
-predict the number of pages to show to the user. A draft of the DQL
-query for pagination would look like:
-
-.. code-block:: sql
-
-    SELECT count(DISTINCT p.id) FROM BlogPost p JOIN p.category c JOIN p.author a WHERE ...
-
-Now you could go and write each of these queries by hand, or you
-can use a tree walker to modify the AST for you. Lets see how the
-API would look for this use-case:
-
-.. code-block:: php
-
-    <?php
-    $pageNum = 1;
-    $query = $em->createQuery($dql);
-    $query->setFirstResult( ($pageNum-1) * 20)->setMaxResults(20);
-    
-    $totalResults = Paginate::count($query);
-    $results = $query->getResult();
-
-The ``Paginate::count(Query $query)`` looks like:
-
-.. code-block:: php
-
-    <?php
-    class Paginate
-    {
-        static public function count(Query $query)
-        {
-            /* @var $countQuery Query */
-            $countQuery = clone $query;
-    
-            $countQuery->setHint(Query::HINT_CUSTOM_TREE_WALKERS, array('DoctrineExtensions\Paginate\CountSqlWalker'));
-            $countQuery->setFirstResult(null)->setMaxResults(null);
-    
-            return $countQuery->getSingleScalarResult();
-        }
-    }
-
-It clones the query, resets the limit clause first and max results
-and registers the ``CountSqlWalker`` custom tree walker which
-will modify the AST to execute a count query. The walkers
-implementation is:
-
-.. code-block:: php
-
-    <?php
-    class CountSqlWalker extends TreeWalkerAdapter
-    {
-        /**
-         * Walks down a SelectStatement AST node, thereby generating the appropriate SQL.
-         *
-         * @return string The SQL.
-         */
-        public function walkSelectStatement(SelectStatement $AST)
-        {
-            $parent = null;
-            $parentName = null;
-            foreach ($this->_getQueryComponents() as $dqlAlias => $qComp) {
-                if ($qComp['parent'] === null && $qComp['nestingLevel'] == 0) {
-                    $parent = $qComp;
-                    $parentName = $dqlAlias;
-                    break;
-                }
-            }
-    
-            $pathExpression = new PathExpression(
-                PathExpression::TYPE_STATE_FIELD | PathExpression::TYPE_SINGLE_VALUED_ASSOCIATION, $parentName,
-                $parent['metadata']->getSingleIdentifierFieldName()
-            );
-            $pathExpression->type = PathExpression::TYPE_STATE_FIELD;
-    
-            $AST->selectClause->selectExpressions = array(
-                new SelectExpression(
-                    new AggregateExpression('count', $pathExpression, true), null
-                )
-            );
-        }
-    }
-
-This will delete any given select expressions and replace them with
-a distinct count query for the root entities primary key. This will
-only work if your entity has only one identifier field (composite
-keys won't work).
-
-Modify the Output Walker to generate Vendor specific SQL
---------------------------------------------------------
-
-Most RMDBS have vendor-specific features for optimizing select
-query execution plans. You can write your own output walker to
-introduce certain keywords using the Query Hint API. A query hint
-can be set via ``Query::setHint($name, $value)`` as shown in the
-previous example with the ``HINT_CUSTOM_TREE_WALKERS`` query hint.
-
-We will implement a custom Output Walker that allows to specify the
-``SQL_NO_CACHE`` query hint.
-
-.. code-block:: php
-
-    <?php
-    $dql = "SELECT p, c, a FROM BlogPost p JOIN p.category c JOIN p.author a WHERE ...";
-    $query = $m->createQuery($dql);
-    $query->setHint(Query::HINT_CUSTOM_OUTPUT_WALKER, 'DoctrineExtensions\Query\MysqlWalker');
-    $query->setHint("mysqlWalker.sqlNoCache", true);
-    $results = $query->getResult();
-
-Our ``MysqlWalker`` will extend the default ``SqlWalker``. We will
-modify the generation of the SELECT clause, adding the
-``SQL_NO_CACHE`` on those queries that need it:
-
-.. code-block:: php
-
-    <?php
-    class MysqlWalker extends SqlWalker
-    {
-         /**
-         * Walks down a SelectClause AST node, thereby generating the appropriate SQL.
-         *
-         * @param $selectClause
-         * @return string The SQL.
-         */
-        public function walkSelectClause($selectClause)
-        {
-            $sql = parent::walkSelectClause($selectClause);
-    
-            if ($this->getQuery()->getHint('mysqlWalker.sqlNoCache') === true) {
-                if ($selectClause->isDistinct) {
-                    $sql = str_replace('SELECT DISTINCT', 'SELECT DISTINCT SQL_NO_CACHE', $sql);
-                } else {
-                    $sql = str_replace('SELECT', 'SELECT SQL_NO_CACHE', $sql);
-                }
-            }
-    
-            return $sql;
-        }
-    }
-
-Writing extensions to the Output Walker requires a very deep
-understanding of the DQL Parser and Walkers, but may offer your
-huge benefits with using vendor specific features. This would still
-allow you write DQL queries instead of NativeQueries to make use of
-vendor specific features.

-DQL User Defined Functions
-==========================
-
-.. sectionauthor:: Benjamin Eberlei <kontakt@beberlei.de>
-
-By default DQL supports a limited subset of all the vendor-specific
-SQL functions common between all the vendors. However in many cases
-once you have decided on a specific database vendor, you will never
-change it during the life of your project. This decision for a
-specific vendor potentially allows you to make use of powerful SQL
-features that are unique to the vendor.
-
-It is worth to mention that Doctrine ORM also allows you to handwrite
-your SQL instead of extending the DQL parser. Extending DQL is sort of an
-advanced extension point. You can map arbitrary SQL to your objects
-and gain access to vendor specific functionalities using the
-``EntityManager#createNativeQuery()`` API as described in
-the :doc:`Native Query <../reference/native-sql>` chapter.
-
-
-The DQL Parser has hooks to register functions that can then be
-used in your DQL queries and transformed into SQL, allowing to
-extend Doctrines Query capabilities to the vendors strength. This
-post explains the User-Defined Functions API (UDF) of the Dql
-Parser and shows some examples to give you some hints how you would
-extend DQL.
-
-There are three types of functions in DQL, those that return a
-numerical value, those that return a string and those that return a
-Date. Your custom method has to be registered as either one of
-those. The return type information is used by the DQL parser to
-check possible syntax errors during the parsing process, for
-example using a string function return value in a math expression.
-
-Registering your own DQL functions
-----------------------------------
-
-You can register your functions adding them to the ORM
-configuration:
-
-.. code-block:: php
-
-    <?php
-    $config = new \Doctrine\ORM\Configuration();
-    $config->addCustomStringFunction($name, $class);
-    $config->addCustomNumericFunction($name, $class);
-    $config->addCustomDatetimeFunction($name, $class);
-    
-    $em = EntityManager::create($dbParams, $config);
-
-The ``$name`` is the name the function will be referred to in the
-DQL query. ``$class`` is a string of a class-name which has to
-extend ``Doctrine\ORM\Query\Node\FunctionNode``. This is a class
-that offers all the necessary API and methods to implement a UDF.
-
-Instead of providing the function class name, you can also provide
-a callable that returns the function object:
-
-.. code-block:: php
-
-    <?php
-    $config = new \Doctrine\ORM\Configuration();
-    $config->addCustomStringFunction($name, function () {
-        return new MyCustomFunction();
-    });
-
-In this post we will implement some MySql specific Date calculation
-methods, which are quite handy in my opinion:
-
-Date Diff
----------
-
-`Mysql's DateDiff function <https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_datediff>`_
-takes two dates as argument and calculates the difference in days
-with ``date1-date2``.
-
-The DQL parser is a top-down recursive descent parser to generate
-the Abstract-Syntax Tree (AST) and uses a TreeWalker approach to
-generate the appropriate SQL from the AST. This makes reading the
-Parser/TreeWalker code manageable in a finite amount of time.
-
-The ``FunctionNode`` class I referred to earlier requires you to
-implement two methods, one for the parsing process (obviously)
-called ``parse`` and one for the TreeWalker process called
-``getSql()``. I show you the code for the DateDiff method and
-discuss it step by step:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * DateDiffFunction ::= "DATEDIFF" "(" ArithmeticPrimary "," ArithmeticPrimary ")"
-     */
-    class DateDiff extends FunctionNode
-    {
-        // (1)
-        public $firstDateExpression = null;
-        public $secondDateExpression = null;
-    
-        public function parse(\Doctrine\ORM\Query\Parser $parser)
-        {
-            $parser->match(Lexer::T_IDENTIFIER); // (2)
-            $parser->match(Lexer::T_OPEN_PARENTHESIS); // (3)
-            $this->firstDateExpression = $parser->ArithmeticPrimary(); // (4)
-            $parser->match(Lexer::T_COMMA); // (5)
-            $this->secondDateExpression = $parser->ArithmeticPrimary(); // (6)
-            $parser->match(Lexer::T_CLOSE_PARENTHESIS); // (3)
-        }
-    
-        public function getSql(\Doctrine\ORM\Query\SqlWalker $sqlWalker)
-        {
-            return 'DATEDIFF(' .
-                $this->firstDateExpression->dispatch($sqlWalker) . ', ' .
-                $this->secondDateExpression->dispatch($sqlWalker) .
-            ')'; // (7)
-        }
-    }
-
-The Parsing process of the DATEDIFF function is going to find two
-expressions the date1 and the date2 values, whose AST Node
-representations will be saved in the variables of the DateDiff
-FunctionNode instance at (1).
-
-The parse() method has to cut the function call "DATEDIFF" and its
-argument into pieces. Since the parser detects the function using a
-lookahead the T\_IDENTIFIER of the function name has to be taken
-from the stack (2), followed by a detection of the arguments in
-(4)-(6). The opening and closing parenthesis have to be detected
-also. This happens during the Parsing process and leads to the
-generation of a DateDiff FunctionNode somewhere in the AST of the
-dql statement.
-
-The ``ArithmeticPrimary`` method call is the most common
-denominator of valid EBNF tokens taken from the
-`DQL EBNF grammar <http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/dql-doctrine-query-language.html#ebnf>`_
-that matches our requirements for valid input into the DateDiff Dql
-function. Picking the right tokens for your methods is a tricky
-business, but the EBNF grammar is pretty helpful finding it, as is
-looking at the Parser source code.
-
-Now in the TreeWalker process we have to pick up this node and
-generate SQL from it, which apparently is quite easy looking at the
-code in (7). Since we don't know which type of AST Node the first
-and second Date expression are we are just dispatching them back to
-the SQL Walker to generate SQL from and then wrap our DATEDIFF
-function call around this output.
-
-Now registering this DateDiff FunctionNode with the ORM using:
-
-.. code-block:: php
-
-    <?php
-    $config = new \Doctrine\ORM\Configuration();
-    $config->addCustomStringFunction('DATEDIFF', 'DoctrineExtensions\Query\MySql\DateDiff');
-
-We can do fancy stuff like:
-
-.. code-block:: sql
-
-    SELECT p FROM DoctrineExtensions\Query\BlogPost p WHERE DATEDIFF(CURRENT_TIME(), p.created) < 7
-
-Date Add
---------
-
-Often useful it the ability to do some simple date calculations in
-your DQL query using
-`MySql's DATE_ADD function <https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_date-add>`_.
-
-I'll skip the blah and show the code for this function:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * DateAddFunction ::=
-     *     "DATE_ADD" "(" ArithmeticPrimary ", INTERVAL" ArithmeticPrimary Identifier ")"
-     */
-    class DateAdd extends FunctionNode
-    {
-        public $firstDateExpression = null;
-        public $intervalExpression = null;
-        public $unit = null;
-    
-        public function parse(\Doctrine\ORM\Query\Parser $parser)
-        {
-            $parser->match(Lexer::T_IDENTIFIER);
-            $parser->match(Lexer::T_OPEN_PARENTHESIS);
-    
-            $this->firstDateExpression = $parser->ArithmeticPrimary();
-    
-            $parser->match(Lexer::T_COMMA);
-            $parser->match(Lexer::T_IDENTIFIER);
-    
-            $this->intervalExpression = $parser->ArithmeticPrimary();
-    
-            $parser->match(Lexer::T_IDENTIFIER);
-    
-            /* @var $lexer Lexer */
-            $lexer = $parser->getLexer();
-            $this->unit = $lexer->token['value'];
-    
-            $parser->match(Lexer::T_CLOSE_PARENTHESIS);
-        }
-    
-        public function getSql(\Doctrine\ORM\Query\SqlWalker $sqlWalker)
-        {
-            return 'DATE_ADD(' .
-                $this->firstDateExpression->dispatch($sqlWalker) . ', INTERVAL ' .
-                $this->intervalExpression->dispatch($sqlWalker) . ' ' . $this->unit .
-            ')';
-        }
-    }
-
-The only difference compared to the DATEDIFF here is, we
-additionally need the ``Lexer`` to access the value of the
-``T_IDENTIFIER`` token for the Date Interval unit, for example the
-MONTH in:
-
-.. code-block:: sql
-
-    SELECT p FROM DoctrineExtensions\Query\BlogPost p WHERE DATE_ADD(CURRENT_TIME(), INTERVAL 4 MONTH) > p.created
-
-The above method now only supports the specification using
-``INTERVAL``, to also allow a real date in DATE\_ADD we need to add
-some decision logic to the parsing process (makes up for a nice
-exercise).
-
-Now as you see, the Parsing process doesn't catch all the possible
-SQL errors, here we don't match for all the valid inputs for the
-interval unit. However where necessary we rely on the database
-vendors SQL parser to show us further errors in the parsing
-process, for example if the Unit would not be one of the supported
-values by MySql.
-
-Conclusion
-----------
-
-Now that you all know how you can implement vendor specific SQL
-functionalities in DQL, we would be excited to see user extensions
-that add vendor specific function packages, for example more math
-functions, XML + GIS Support, Hashing functions and so on.
-
-For ORM we will come with the current set of functions, however for
-a future version we will re-evaluate if we can abstract even more
-vendor sql functions and extend the DQL languages scope.
-
-Code for this Extension to DQL and other Doctrine Extensions can be
-found
-`in the GitHub DoctrineExtensions repository <http://github.com/beberlei/DoctrineExtensions>`_.

-Entities in the Session
-=======================
-
-There are several use-cases to save entities in the session, for example:
-
-1.  User object
-2.  Multi-step forms
-
-To achieve this with Doctrine you have to pay attention to some details to get
-this working.
-
-Merging entity into an EntityManager
-------------------------------------
-
-In Doctrine an entity objects has to be "managed" by an EntityManager to be
-updateable. Entities saved into the session are not managed in the next request
-anymore. This means that you have to register these entities with an
-EntityManager again if you want to change them or use them as part of
-references between other entities. You can achieve this by calling
-``EntityManager#merge()``.
-
-For a representative User object the code to get turn an instance from
-the session into a managed Doctrine object looks like this:
-
-.. code-block:: php
-
-    <?php
-    require_once 'bootstrap.php';
-    $em = GetEntityManager(); // creates an EntityManager 
-
-    session_start();
-    if (isset($_SESSION['user']) && $_SESSION['user'] instanceof User) {
-        $user = $_SESSION['user']; 
-        $user = $em->merge($user);
-    }
-
-.. note::
-
-    A frequent mistake is not to get the merged user object from the return
-    value of ``EntityManager#merge()``. The entity object passed to merge is
-    not necessarily the same object that is returned from the method.
-
-Serializing entity into the session
------------------------------------
-
-Entities that are serialized into the session normally contain references to
-other entities as well. Think of the user entity has a reference to their
-articles, groups, photos or many other different entities. If you serialize
-this object into the session then you don't want to serialize the related
-entities as well. This is why you should call ``EntityManager#detach()`` on this
-object or implement the __sleep() magic method on your entity.
-
-.. code-block:: php
-
-    <?php
-    require_once 'bootstrap.php';
-    $em = GetEntityManager(); // creates an EntityManager 
-
-    $user = $em->find("User", 1);
-    $em->detach($user);
-    $_SESSION['user'] = $user;
-
-.. note::
-
-    When you called detach on your objects they get "unmanaged" with that
-    entity manager. This means you cannot use them as part of write operations
-    during ``EntityManager#flush()`` anymore in this request.

-Implementing ArrayAccess for Domain Objects
-===========================================
-
-.. sectionauthor:: Roman Borschel (roman@code-factory.org)
-
-This recipe will show you how to implement ArrayAccess for your
-domain objects in order to allow more uniform access, for example
-in templates. In these examples we will implement ArrayAccess on a
-`Layer Supertype <http://martinfowler.com/eaaCatalog/layerSupertype.html>`_
-for all our domain objects.
-
-Option 1
---------
-
-In this implementation we will make use of PHPs highly dynamic
-nature to dynamically access properties of a subtype in a supertype
-at runtime. Note that this implementation has 2 main caveats:
-
-
--  It will not work with private fields
--  It will not go through any getters/setters
-
-.. code-block:: php
-
-    <?php
-    abstract class DomainObject implements ArrayAccess
-    {
-        public function offsetExists($offset) {
-            return isset($this->$offset);
-        }
-    
-        public function offsetSet($offset, $value) {
-            $this->$offset = $value;
-        }
-    
-        public function offsetGet($offset) {
-            return $this->$offset;

-    
-        public function offsetUnset($offset) {
-            $this->$offset = null;
-        }
-    }
-
-Option 2
---------
-
-In this implementation we will dynamically invoke getters/setters.
-Again we use PHPs dynamic nature to invoke methods on a subtype
-from a supertype at runtime. This implementation has the following
-caveats:
-
-
--  It relies on a naming convention
--  The semantics of offsetExists can differ
--  offsetUnset will not work with typehinted setters
-
-.. code-block:: php
-
-    <?php
-    abstract class DomainObject implements ArrayAccess
-    {
-        public function offsetExists($offset) {
-            // In this example we say that exists means it is not null
-            $value = $this->{"get$offset"}();
-            return $value !== null;
-        }
-    
-        public function offsetSet($offset, $value) {
-            $this->{"set$offset"}($value);
-        }
-    
-        public function offsetGet($offset) {
-            return $this->{"get$offset"}();
-        }
-    
-        public function offsetUnset($offset) {
-            $this->{"set$offset"}(null);
-        }
-    }
-
-Read-only
----------
-
-You can slightly tweak option 1 or option 2 in order to make array
-access read-only. This will also circumvent some of the caveats of
-each option. Simply make offsetSet and offsetUnset throw an
-exception (i.e. BadMethodCallException).
-
-.. code-block:: php
-
-    <?php
-    abstract class DomainObject implements ArrayAccess
-    {
-        public function offsetExists($offset) {
-            // option 1 or option 2
-        }
-    
-        public function offsetSet($offset, $value) {
-            throw new BadMethodCallException("Array access of class " . get_class($this) . " is read-only!");
-        }
-    
-        public function offsetGet($offset) {
-            // option 1 or option 2
-        }
-    
-        public function offsetUnset($offset) {
-            throw new BadMethodCallException("Array access of class " . get_class($this) . " is read-only!");

-`Layer Supertype <http://martinfowler.com/eaaCatalog/layerSupertype.html>`_
-for all our domain objects.
-
-Implementing NotifyPropertyChanged
-----------------------------------
-
-The NOTIFY policy is based on the assumption that the entities
-notify interested listeners of changes to their properties. For
-that purpose, a class that wants to use this policy needs to
-implement the ``NotifyPropertyChanged`` interface from the
-``Doctrine\Common`` namespace.
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Persistence\NotifyPropertyChanged;
-    use Doctrine\Persistence\PropertyChangedListener;
-    
-    abstract class DomainObject implements NotifyPropertyChanged
-    {
-        private $listeners = array();
-    
-        public function addPropertyChangedListener(PropertyChangedListener $listener) {
-            $this->listeners[] = $listener;
-        }
-    
-        /** Notifies listeners of a change. */
-        protected function onPropertyChanged($propName, $oldValue, $newValue) {
-            if ($this->listeners) {
-                foreach ($this->listeners as $listener) {
-                    $listener->propertyChanged($this, $propName, $oldValue, $newValue);
-                }
-            }
-        }
-    }
-
-Then, in each property setter of concrete, derived domain classes,
-you need to invoke onPropertyChanged as follows to notify
-listeners:
-
-.. code-block:: php
-
-    <?php
-    // Mapping not shown, either in annotations, xml or yaml as usual
-    class MyEntity extends DomainObject
-    {
-        private $data;
-        // ... other fields as usual
-    
-        public function setData($data) {
-            if ($data != $this->data) { // check: is it actually modified?
-                $this->onPropertyChanged('data', $this->data, $data);
-                $this->data = $data;
-            }
-        }
-    }
-
-The check whether the new value is different from the old one is
-not mandatory but recommended. That way you can avoid unnecessary
-updates and also have full control over when you consider a
-property changed.

-Implementing Wakeup or Clone
-============================
-
-.. sectionauthor:: Roman Borschel (roman@code-factory.org)
-
-As explained in the
-`restrictions for entity classes in the manual <http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/architecture.html#entities>`_,
-it is usually not allowed for an entity to implement ``__wakeup``
-or ``__clone``, because Doctrine makes special use of them.
-However, it is quite easy to make use of these methods in a safe
-way by guarding the custom wakeup or clone code with an entity
-identity check, as demonstrated in the following sections.
-
-Safely implementing __wakeup
-----------------------------
-
-To safely implement ``__wakeup``, simply enclose your
-implementation code in an identity check as follows:
-
-.. code-block:: php
-
-    <?php
-    class MyEntity
-    {
-        private $id; // This is the identifier of the entity.
-        //...
-    
-        public function __wakeup()
-        {
-            // If the entity has an identity, proceed as normal.
-            if ($this->id) {
-                // ... Your code here as normal ...
-            }
-            // otherwise do nothing, do NOT throw an exception!
-        }
-    
-        //...
-    }
-
-Safely implementing __clone
----------------------------
-
-Safely implementing ``__clone`` is pretty much the same:
-
-.. code-block:: php
-
-    <?php
-    class MyEntity
-    {
-        private $id; // This is the identifier of the entity.
-        //...
-    
-        public function __clone()
-        {
-            // If the entity has an identity, proceed as normal.
-            if ($this->id) {
-                // ... Your code here as normal ...
-            }
-            // otherwise do nothing, do NOT throw an exception!
-        }
-    
-        //...
-    }
-
-Summary
--------
-
-As you have seen, it is quite easy to safely make use of
-``__wakeup`` and ``__clone`` in your entities without adding any
-really Doctrine-specific or Doctrine-dependant code.
-
-These implementations are possible and safe because when Doctrine
-invokes these methods, the entities never have an identity (yet).
-Furthermore, it is possibly a good idea to check for the identity
-in your code anyway, since it's rarely the case that you want to
-unserialize or clone an entity with no identity.

-Mysql Enums
-===========
-
-The type system of Doctrine ORM consists of flyweights, which means there is only
-one instance of any given type. Additionally types do not contain state. Both
-assumptions make it rather complicated to work with the Enum Type of MySQL that
-is used quite a lot by developers.
-
-When using Enums with a non-tweaked Doctrine ORM application you will get
-errors from the Schema-Tool commands due to the unknown database type "enum".
-By default Doctrine does not map the MySQL enum type to a Doctrine type.
-This is because Enums contain state (their allowed values) and Doctrine
-types don't.
-
-This cookbook entry shows two possible solutions to work with MySQL enums.
-But first a word of warning. The MySQL Enum type has considerable downsides:
-
--  Adding new values requires to rebuild the whole table, which can take hours
-   depending on the size.
--  Enums are ordered in the way the values are specified, not in their "natural" order.
--  Enums validation mechanism for allowed values is not necessarily good,
-   specifying invalid values leads to an empty enum for the default MySQL error
-   settings. You can easily replicate the "allow only some values" requirement
-   in your Doctrine entities.
-
-Solution 1: Mapping to Varchars
--------------------------------
-
-You can map ENUMs to varchars. You can register MySQL ENUMs to map to Doctrine
-varchars. This way Doctrine always resolves ENUMs to Doctrine varchars. It
-will even detect this match correctly when using SchemaTool update commands.
-
-.. code-block:: php
-
-    <?php
-    $conn = $em->getConnection();
-    $conn->getDatabasePlatform()->registerDoctrineTypeMapping('enum', 'string');
-
-In this case you have to ensure that each varchar field that is an enum in the
-database only gets passed the allowed values. You can easily enforce this in your
-entities:
-
-.. code-block:: php
-
-    <?php
-    /** @Entity */
-    class Article
-    {
-        const STATUS_VISIBLE = 'visible';
-        const STATUS_INVISIBLE = 'invisible';
-
-        /** @Column(type="string") */
-        private $status;
-
-        public function setStatus($status)
-        {
-            if (!in_array($status, array(self::STATUS_VISIBLE, self::STATUS_INVISIBLE))) {
-                throw new \InvalidArgumentException("Invalid status");
-            }
-            $this->status = $status;
-        }
-    }
-
-If you want to actively create enums through the Doctrine Schema-Tool by using
-the **columnDefinition** attribute.
-
-.. code-block:: php
-
-    <?php
-    /** @Entity */
-    class Article
-    {
-        /** @Column(type="string", columnDefinition="ENUM('visible', 'invisible')") */
-        private $status;
-    }
-
-In this case however Schema-Tool update will have a hard time not to request changes for this column on each call.
-
-Solution 2: Defining a Type
----------------------------
-
-You can make a stateless ENUM type by creating a type class for each unique set of ENUM values.
-For example for the previous enum type:
-
-.. code-block:: php
-
-    <?php
-    namespace MyProject\DBAL;
-
-    use Doctrine\DBAL\Types\Type;
-    use Doctrine\DBAL\Platforms\AbstractPlatform;
-
-    class EnumVisibilityType extends Type
-    {
-        const ENUM_VISIBILITY = 'enumvisibility';
-        const STATUS_VISIBLE = 'visible';
-        const STATUS_INVISIBLE = 'invisible';
-
-        public function getSQLDeclaration(array $fieldDeclaration, AbstractPlatform $platform)
-        {
-            return "ENUM('visible', 'invisible')";
-        }
-
-        public function convertToPHPValue($value, AbstractPlatform $platform)
-        {
-            return $value;
-        }
-
-        public function convertToDatabaseValue($value, AbstractPlatform $platform)
-        {
-            if (!in_array($value, array(self::STATUS_VISIBLE, self::STATUS_INVISIBLE))) {
-                throw new \InvalidArgumentException("Invalid status");
-            }
-            return $value;
-        }
-
-        public function getName()
-        {
-            return self::ENUM_VISIBILITY;
-        }
-
-        public function requiresSQLCommentHint(AbstractPlatform $platform)
-        {
-            return true;
-        }
-    }
-
-You can register this type with ``Type::addType('enumvisibility', 'MyProject\DBAL\EnumVisibilityType');``.
-Then in your entity you can just use this type:
-
-.. code-block:: php
-
-    <?php
-    /** @Entity */
-    class Article
-    {
-        /** @Column(type="enumvisibility") */
-        private $status;
-    }
-
-You can generalize this approach easily to create a base class for enums:
-
-.. code-block:: php
-
-    <?php
-    namespace MyProject\DBAL;
-
-    use Doctrine\DBAL\Types\Type;
-    use Doctrine\DBAL\Platforms\AbstractPlatform;
-
-    abstract class EnumType extends Type
-    {
-        protected $name;
-        protected $values = array();
-
-        public function getSQLDeclaration(array $fieldDeclaration, AbstractPlatform $platform)
-        {
-            $values = array_map(function($val) { return "'".$val."'"; }, $this->values);
-
-            return "ENUM(".implode(", ", $values).")";
-        }
-
-        public function convertToPHPValue($value, AbstractPlatform $platform)
-        {
-            return $value;
-        }
-
-        public function convertToDatabaseValue($value, AbstractPlatform $platform)
-        {
-            if (!in_array($value, $this->values)) {
-                throw new \InvalidArgumentException("Invalid '".$this->name."' value.");
-            }
-            return $value;
-        }
-
-        public function getName()
-        {
-            return $this->name;
-        }
-
-        public function requiresSQLCommentHint(AbstractPlatform $platform)
-        {
-            return true;
-        }
-    }
-
-With this base class you can define an enum as easily as:
-
-.. code-block:: php
-
-    <?php
-    namespace MyProject\DBAL;
-
-    class EnumVisibilityType extends EnumType
-    {
-        protected $name = 'enumvisibility';
-        protected $values = array('visible', 'invisible');
-    }

-Keeping your Modules independent
-=================================
-
-One of the goals of using modules is to create discrete units of functionality
-that do not have many (if any) dependencies, allowing you to use that
-functionality in other applications without including unnecessary items.
-
-Doctrine ORM includes a new utility called the ``ResolveTargetEntityListener``,
-that functions by intercepting certain calls inside Doctrine and rewrite
-targetEntity parameters in your metadata mapping at runtime. It means that
-in your bundle you are able to use an interface or abstract class in your
-mappings and expect correct mapping to a concrete entity at runtime.
-
-This functionality allows you to define relationships between different entities
-but not making them hard dependencies.
-
-Background
-----------
-
-In the following example, the situation is we have an `InvoiceModule`
-which provides invoicing functionality, and a `CustomerModule` that
-contains customer management tools. We want to keep these separated,
-because they can be used in other systems without each other, but for
-our application we want to use them together.
-
-In this case, we have an ``Invoice`` entity with a relationship to a
-non-existent object, an ``InvoiceSubjectInterface``. The goal is to get
-the ``ResolveTargetEntityListener`` to replace any mention of the interface
-with a real object that implements that interface.
-
-Set up
-------
-
-We're going to use the following basic entities (which are incomplete
-for brevity) to explain how to set up and use the RTEL.
-
-A Customer entity
-
-.. code-block:: php
-
-    <?php
-    // src/Acme/AppModule/Entity/Customer.php
-
-    namespace Acme\AppModule\Entity;
-
-    use Doctrine\ORM\Mapping as ORM;
-    use Acme\CustomerModule\Entity\Customer as BaseCustomer;
-    use Acme\InvoiceModule\Model\InvoiceSubjectInterface;
-
-    /**
-     * @ORM\Entity
-     * @ORM\Table(name="customer")
-     */
-    class Customer extends BaseCustomer implements InvoiceSubjectInterface
-    {
-        // In our example, any methods defined in the InvoiceSubjectInterface
-        // are already implemented in the BaseCustomer
-    }
-
-An Invoice entity
-
-.. code-block:: php
-
-    <?php
-    // src/Acme/InvoiceModule/Entity/Invoice.php
-
-    namespace Acme\InvoiceModule\Entity;
-
-    use Doctrine\ORM\Mapping AS ORM;
-    use Acme\InvoiceModule\Model\InvoiceSubjectInterface;
-
-    /**
-     * Represents an Invoice.
-     *
-     * @ORM\Entity
-     * @ORM\Table(name="invoice")
-     */
-    class Invoice
-    {
-        /**
-         * @ORM\ManyToOne(targetEntity="Acme\InvoiceModule\Model\InvoiceSubjectInterface")
-         * @var InvoiceSubjectInterface
-         */
-        protected $subject;
-    }
-
-An InvoiceSubjectInterface
-
-.. code-block:: php
-
-    <?php
-    // src/Acme/InvoiceModule/Model/InvoiceSubjectInterface.php
-
-    namespace Acme\InvoiceModule\Model;
-
-    /**
-     * An interface that the invoice Subject object should implement.
-     * In most circumstances, only a single object should implement
-     * this interface as the ResolveTargetEntityListener can only
-     * change the target to a single object.
-     */
-    interface InvoiceSubjectInterface
-    {
-        // List any additional methods that your InvoiceModule
-        // will need to access on the subject so that you can
-        // be sure that you have access to those methods.
-
-        /**
-         * @return string
-         */
-        public function getName();
-    }
-
-Next, we need to configure the listener. Add this to the area you set up Doctrine. You
-must set this up in the way outlined below, otherwise you can not be guaranteed that
-the targetEntity resolution will occur reliably:
-
-.. code-block:: php
-
-    <?php
-    $evm  = new \Doctrine\Common\EventManager;
-    $rtel = new \Doctrine\ORM\Tools\ResolveTargetEntityListener;
-
-    // Adds a target-entity class
-    $rtel->addResolveTargetEntity('Acme\\InvoiceModule\\Model\\InvoiceSubjectInterface', 'Acme\\CustomerModule\\Entity\\Customer', array());
-
-    // Add the ResolveTargetEntityListener
-    $evm->addEventListener(Doctrine\ORM\Events::loadClassMetadata, $rtel);
-
-    $em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config, $evm);
-
-Final Thoughts
---------------
-
-With the ``ResolveTargetEntityListener``, we are able to decouple our
-bundles, keeping them usable by themselves, but still being able to
-define relationships between different objects. By using this method,
-I've found my bundles end up being easier to maintain independently.

-SQL-Table Prefixes
-==================
-
-This recipe is intended as an example of implementing a
-loadClassMetadata listener to provide a Table Prefix option for
-your application. The method used below is not a hack, but fully
-integrates into the Doctrine system, all SQL generated will include
-the appropriate table prefix.
-
-In most circumstances it is desirable to separate different
-applications into individual databases, but in certain cases, it
-may be beneficial to have a table prefix for your Entities to
-separate them from other vendor products in the same database.
-
-Implementing the listener
--------------------------
-
-The listener in this example has been set up with the
-DoctrineExtensions namespace. You create this file in your
-library/DoctrineExtensions directory, but will need to set up
-appropriate autoloaders.
-
-.. code-block:: php
-
-    <?php
-    
-    namespace DoctrineExtensions;
-    use \Doctrine\ORM\Event\LoadClassMetadataEventArgs;
-    
-    class TablePrefix
-    {
-        protected $prefix = '';
-    
-        public function __construct($prefix)
-        {
-            $this->prefix = (string) $prefix;
-        }
-    
-        public function loadClassMetadata(LoadClassMetadataEventArgs $eventArgs)
-        {
-            $classMetadata = $eventArgs->getClassMetadata();
-
-            if (!$classMetadata->isInheritanceTypeSingleTable() || $classMetadata->getName() === $classMetadata->rootEntityName) {
-                $classMetadata->setPrimaryTable([
-                    'name' => $this->prefix . $classMetadata->getTableName()
-                ]);
-            }
-
-            foreach ($classMetadata->getAssociationMappings() as $fieldName => $mapping) {
-                if ($mapping['type'] == \Doctrine\ORM\Mapping\ClassMetadataInfo::MANY_TO_MANY && $mapping['isOwningSide']) {
-                    $mappedTableName = $mapping['joinTable']['name'];
-                    $classMetadata->associationMappings[$fieldName]['joinTable']['name'] = $this->prefix . $mappedTableName;
-                }
-            }
-        }
-
-    }
-
-Telling the EntityManager about our listener
---------------------------------------------
-
-A listener of this type must be set up before the EntityManager has
-been initialised, otherwise an Entity might be created or cached
-before the prefix has been set.
-
-.. note::
-
-    If you set this listener up, be aware that you will need
-    to clear your caches and drop then recreate your database schema.
-
-
-.. code-block:: php
-
-    <?php
-    
-    // $connectionOptions and $config set earlier
-    
-    $evm = new \Doctrine\Common\EventManager;
-    
-    // Table Prefix
-    $tablePrefix = new \DoctrineExtensions\TablePrefix('prefix_');
-    $evm->addEventListener(\Doctrine\ORM\Events::loadClassMetadata, $tablePrefix);
-    
-    $em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config, $evm);

-Strategy-Pattern
-================
-
-This recipe will give you a short introduction on how to design
-similar entities without using expensive (i.e. slow) inheritance
-but with not more than *the well-known strategy pattern* event
-listeners
-
-Scenario / Problem
-------------------
-
-Given a Content-Management-System, we probably want to add / edit
-some so-called "blocks" and "panels". What are they for?
-
-
--  A block might be a registration form, some text content, a table
-   with information. A good example might also be a small calendar.
--  A panel is by definition a block that can itself contain blocks.
-   A good example for a panel might be a sidebar box: You could easily
-   add a small calendar into it.
-
-So, in this scenario, when building your CMS, you will surely add
-lots of blocks and panels to your pages and you will find yourself
-highly uncomfortable because of the following:
-
-
--  Every existing page needs to know about the panels it contains -
-   therefore, you'll have an association to your panels. But if you've
-   got several types of panels - what do you do? Add an association to
-   every panel-type? This wouldn't be flexible. You might be tempted
-   to add an AbstractPanelEntity and an AbstractBlockEntity that use
-   class inheritance. Your page could then only confer to the
-   AbstractPanelType and Doctrine ORM would do the rest for you, i.e.
-   load the right entities. But - you'll for sure have lots of panels
-   and blocks, and even worse, you'd have to edit the discriminator
-   map *manually* every time you or another developer implements a new
-   block / entity. This would tear down any effort of modular
-   programming.
-
-Therefore, we need something that's far more flexible.
-
-Solution
---------
-
-The solution itself is pretty easy. We will have one base class
-that will be loaded via the page and that has specific behaviour -
-a Block class might render the front-end and even the backend, for
-example. Now, every block that you'll write might look different or
-need different data - therefore, we'll offer an API to these
-methods but internally, we use a strategy that exactly knows what
-to do.
-
-First of all, we need to make sure that we have an interface that
-contains every needed action. Such actions would be rendering the
-front-end or the backend, solving dependencies (blocks that are
-supposed to be placed in the sidebar could refuse to be placed in
-the middle of your page, for example).
-
-Such an interface could look like this:
-
-
-.. code-block:: php
-
-    <?php
-    /**
-     * This interface defines the basic actions that a block / panel needs to support.
-     *
-     * Every blockstrategy is *only* responsible for rendering a block and declaring some basic
-     * support, but *not* for updating its configuration etc. For this purpose, use controllers
-     * and models.
-     */
-    interface BlockStrategyInterface {
-        /**
-         * This could configure your entity
-         */
-        public function setConfig(Config\EntityConfig $config);
-
-        /**
-         * Returns the config this strategy is configured with.
-         * @return Core\Model\Config\EntityConfig
-         */
-        public function getConfig();
-
-        /**
-         * Set the view object.
-         * @param  \Zend_View_Interface $view
-         * @return \Zend_View_Helper_Interface
-         */
-        public function setView(\Zend_View_Interface $view);
-   
-        /**
-         * @return \Zend_View_Interface
-         */
-        public function getView();

-            $this->strategyClassName = get_class($strategy);
-            $strategy->setBlockEntity($this);
-        }
-
-Now, the important point is that $strategyClassName is a Doctrine ORM
-field, i.e. Doctrine will persist this value. This is only the
-class name of your strategy and not an instance!
-
-Finishing your strategy pattern, we hook into the Doctrine postLoad
-event and check whether a block has been loaded. If so, you will
-initialize it - i.e. get the strategies classname, create an
-instance of it and set it via setStrategyBlock().
-
-This might look like this:
-
-.. code-block:: php
-
-    <?php
-    use \Doctrine\ORM,
-        \Doctrine\Common;
-    
-    /**
-     * The BlockStrategyEventListener will initialize a strategy after the
-     * block itself was loaded.
-     */
-    class BlockStrategyEventListener implements Common\EventSubscriber {
-    
-        protected $view;
-    
-        public function __construct(\Zend_View_Interface $view) {
-            $this->view = $view;
-        }
-    
-        public function getSubscribedEvents() {
-           return array(ORM\Events::postLoad);
-        }
-    
-        public function postLoad(ORM\Event\LifecycleEventArgs $args) {
-            $blockItem = $args->getEntity();
-    
-            // Both blocks and panels are instances of Block\AbstractBlock
-            if ($blockItem instanceof Block\AbstractBlock) {
-                $strategy  = $blockItem->getStrategyClassName();
-                $strategyInstance = new $strategy();
-                if (null !== $blockItem->getConfig()) {
-                    $strategyInstance->setConfig($blockItem->getConfig());
-                }
-                $strategyInstance->setView($this->view);
-                $blockItem->setStrategy($strategyInstance);
-            }
-        }
-    }
-
-In this example, even some variables are set - like a view object
-or a specific configuration object.

-Validation of Entities
-======================
-
-.. sectionauthor:: Benjamin Eberlei <kontakt@beberlei.de>
-
-Doctrine ORM does not ship with any internal validators, the reason
-being that we think all the frameworks out there already ship with
-quite decent ones that can be integrated into your Domain easily.
-What we offer are hooks to execute any kind of validation.
-
-.. note::
-
-    You don't need to validate your entities in the lifecycle
-    events. Its only one of many options. Of course you can also
-    perform validations in value setters or any other method of your
-    entities that are used in your code.
-
-
-Entities can register lifecycle event methods with Doctrine that
-are called on different occasions. For validation we would need to
-hook into the events called before persisting and updating. Even
-though we don't support validation out of the box, the
-implementation is even simpler than in Doctrine 1 and you will get
-the additional benefit of being able to re-use your validation in
-any other part of your domain.
-
-Say we have an ``Order`` with several ``OrderLine`` instances. We
-never want to allow any customer to order for a larger sum than they
-are allowed to:
-
-.. code-block:: php
-
-    <?php
-    class Order
-    {
-        public function assertCustomerAllowedBuying()
-        {
-            $orderLimit = $this->customer->getOrderLimit();
-    
-            $amount = 0;
-            foreach ($this->orderLines as $line) {
-                $amount += $line->getAmount();
-            }
-    
-            if ($amount > $orderLimit) {
-                throw new CustomerOrderLimitExceededException();
-            }
-        }
-    }
-
-Now this is some pretty important piece of business logic in your
-code, enforcing it at any time is important so that customers with
-a unknown reputation don't owe your business too much money.
-
-We can enforce this constraint in any of the metadata drivers.
-First Annotations:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * @Entity
-     * @HasLifecycleCallbacks
-     */
-    class Order
-    {
-        /**
-         * @PrePersist @PreUpdate
-         */
-        public function assertCustomerAllowedBuying() {}
-    }
-
-In XML Mappings:
-
-.. code-block:: xml
-
-    <doctrine-mapping>
-        <entity name="Order">
-            <lifecycle-callbacks>
-                <lifecycle-callback type="prePersist" method="assertCustomerallowedBuying" />
-                <lifecycle-callback type="preUpdate" method="assertCustomerallowedBuying" />
-            </lifecycle-callbacks>
-        </entity>
-    </doctrine-mapping>
-
-YAML needs some little change yet, to allow multiple lifecycle
-events for one method, this will happen before Beta 1 though.
-
-Now validation is performed whenever you call
-``EntityManager#persist($order)`` or when you call
-``EntityManager#flush()`` and an order is about to be updated. Any
-Exception that happens in the lifecycle callbacks will be caught by
-the EntityManager and the current transaction is rolled back.
-
-Of course you can do any type of primitive checks, not null,
-email-validation, string size, integer and date ranges in your
-validation callbacks.
-
-.. code-block:: php
-
-    <?php
-    class Order
-    {
-        /**
-         * @PrePersist @PreUpdate
-         */
-        public function validate()
-        {
-            if (!($this->plannedShipDate instanceof DateTime)) {
-                throw new ValidateException();
-            }
-    
-            if ($this->plannedShipDate->format('U') < time()) {
-                throw new ValidateException();
-            }
-    
-            if ($this->customer == null) {
-                throw new OrderRequiresCustomerException();
-            }
-        }
-    }
-
-What is nice about lifecycle events is, you can also re-use the
-methods at other places in your domain, for example in combination
-with your form library. Additionally there is no limitation in the
-number of methods you register on one particular event, i.e. you
-can register multiple methods for validation in "PrePersist" or
-"PreUpdate" or mix and share them in any combinations between those
-two events.
-
-There is no limit to what you can and can't validate in
-"PrePersist" and "PreUpdate" as long as you don't create new entity
-instances. This was already discussed in the previous blog post on
-the Versionable extension, which requires another type of event
-called "onFlush".

-Working with DateTime Instances
-===============================
-
-There are many nitty gritty details when working with PHPs DateTime instances. You have to know their inner
-workings pretty well not to make mistakes with date handling. This cookbook entry holds several
-interesting pieces of information on how to work with PHP DateTime instances in ORM.
-
-DateTime changes are detected by Reference
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-When calling ``EntityManager#flush()`` Doctrine computes the changesets of all the currently managed entities
-and saves the differences to the database. In case of object properties (@Column(type="datetime") or @Column(type="object"))
-these comparisons are always made **BY REFERENCE**. That means the following change will **NOT** be saved into the database:
-
-.. code-block:: php
-
-    <?php
-    /** @Entity */
-    class Article
-    {
-        /** @Column(type="datetime") */
-        private $updated;
-
-        public function setUpdated()
-        {
-            // will NOT be saved in the database
-            $this->updated->modify("now");
-        }
-    }
-
-The way to go would be:
-
-.. code-block:: php
-
-    <?php
-    class Article
-    {
-        public function setUpdated()
-        {
-            // WILL be saved in the database
-            $this->updated = new \DateTime("now");
-        }
-    }
-
-Default Timezone Gotcha
-~~~~~~~~~~~~~~~~~~~~~~~
-
-By default Doctrine assumes that you are working with a default timezone. Each DateTime instance that
-is created by Doctrine will be assigned the timezone that is currently the default, either through
-the ``date.timezone`` ini setting or by calling ``date_default_timezone_set()``.
-
-This is very important to handle correctly if your application runs on different servers or is moved from one to another server
-(with different timezone settings). You have to make sure that the timezone is the correct one
-on all this systems.
-
-Handling different Timezones with the DateTime Type
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If you first come across the requirement to save different timezones you may be still optimistic about how
-to manage this mess,
-however let me crush your expectations fast. There is not a single database out there (supported by Doctrine ORM)
-that supports timezones correctly. Correctly here means that you can cover all the use-cases that
-can come up with timezones. If you don't believe me you should read up on `Storing DateTime
-in Databases <http://derickrethans.nl/storing-date-time-in-database.html>`_.
-
-The problem is simple. Not a single database vendor saves the timezone, only the differences to UTC.
-However with frequent daylight saving and political timezone changes you can have a UTC offset that moves
-in different offset directions depending on the real location.
-
-The solution for this dilemma is simple. Don't use timezones with DateTime and Doctrine ORM. However there is a workaround
-that even allows correct date-time handling with timezones:
-
-1. Always convert any DateTime instance to UTC.
-2. Only set Timezones for displaying purposes
-3. Save the Timezone in the Entity for persistence.
-
-Say we have an application for an international postal company and employees insert events regarding postal-package
-around the world, in their current timezones. To determine the exact time an event occurred means to save both
-the UTC time at the time of the booking and the timezone the event happened in.
-
-.. code-block:: php
-
-    <?php
-
-    namespace DoctrineExtensions\DBAL\Types;
-
-    use Doctrine\DBAL\Platforms\AbstractPlatform;
-    use Doctrine\DBAL\Types\ConversionException;
-    use Doctrine\DBAL\Types\DateTimeType;
-
-    class UTCDateTimeType extends DateTimeType
-    {
-        /**
-         * @var \DateTimeZone
-         */
-        private static $utc;
-
-        public function convertToDatabaseValue($value, AbstractPlatform $platform)
-        {
-            if ($value instanceof \DateTime) {
-                $value->setTimezone(self::getUtc());
-            }
-
-            return parent::convertToDatabaseValue($value, $platform);
-        }
-
-        public function convertToPHPValue($value, AbstractPlatform $platform)
-        {
-            if (null === $value || $value instanceof \DateTime) {
-                return $value;
-            }
-
-            $converted = \DateTime::createFromFormat(
-                $platform->getDateTimeFormatString(),
-                $value,
-                self::getUtc()
-            );
-
-            if (! $converted) {
-                throw ConversionException::conversionFailedFormat(
-                    $value,
-                    $this->getName(),
-                    $platform->getDateTimeFormatString()
-                );
-            }
-
-            return $converted;
-        }
-        
-        private static function getUtc(): \DateTimeZone
-        {
-            return self::$utc ?: self::$utc = new \DateTimeZone('UTC');
-        }
-    }
-
-This database type makes sure that every DateTime instance is always saved in UTC, relative
-to the current timezone that the passed DateTime instance has.
-
-To actually use this new type instead of the default ``datetime`` type, you need to run following
-code before bootstrapping the ORM:
-
-.. code-block:: php
-
-    <?php
-
-    use Doctrine\DBAL\Types\Type;
-    use DoctrineExtensions\DBAL\Types\UTCDateTimeType;
-
-    Type::overrideType('datetime', UTCDateTimeType::class);
-    Type::overrideType('datetimetz', UTCDateTimeType::class);
-
-
-To be able to transform these values
-back into their real timezone you have to save the timezone in a separate field of the entity
-requiring timezoned datetimes:
-
-.. code-block:: php
-
-    <?php
-    namespace Shipping;
-
-    /**
-     * @Entity
-     */
-    class Event
-    {
-        /** @Column(type="datetime") */
-        private $created;
-
-        /** @Column(type="string") */
-        private $timezone;
-
-        /**
-         * @var bool
-         */
-        private $localized = false;
-
-        public function __construct(\DateTime $createDate)
-        {
-            $this->localized = true;
-            $this->created = $createDate;
-            $this->timezone = $createDate->getTimeZone()->getName();
-        }
-
-        public function getCreated()
-        {
-            if (!$this->localized) {
-                $this->created->setTimeZone(new \DateTimeZone($this->timezone));
-            }
-            return $this->created;
-        }
-    }
-
-This snippet makes use of the previously discussed "changeset by reference only" property of
-objects. That means a new DateTime will only be used during updating if the reference
-changes between retrieval and flush operation. This means we can easily go and modify
-the instance by setting the previous local timezone.

-Advanced Configuration
-======================
-
-The configuration of the EntityManager requires a
-``Doctrine\ORM\Configuration`` instance as well as some database
-connection parameters. This example shows all the potential
-steps of configuration.
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\EntityManager,
-        Doctrine\ORM\Configuration;
-
-    // ...
-
-    if ($applicationMode == "development") {
-        $cache = new \Doctrine\Common\Cache\ArrayCache;
-    } else {
-        $cache = new \Doctrine\Common\Cache\ApcCache;
-    }
-
-    $config = new Configuration;
-    $config->setMetadataCacheImpl($cache);
-    $driverImpl = $config->newDefaultAnnotationDriver('/path/to/lib/MyProject/Entities');
-    $config->setMetadataDriverImpl($driverImpl);
-    $config->setQueryCacheImpl($cache);
-    $config->setProxyDir('/path/to/myproject/lib/MyProject/Proxies');
-    $config->setProxyNamespace('MyProject\Proxies');
-
-    if ($applicationMode == "development") {
-        $config->setAutoGenerateProxyClasses(true);
-    } else {
-        $config->setAutoGenerateProxyClasses(false);
-    }
-
-    $connectionOptions = array(
-        'driver' => 'pdo_sqlite',
-        'path' => 'database.sqlite'
-    );
-
-    $em = EntityManager::create($connectionOptions, $config);
-
-.. note::
-
-    Do not use Doctrine without a metadata and query cache!
-    Doctrine is optimized for working with caches. The main
-    parts in Doctrine that are optimized for caching are the metadata
-    mapping information with the metadata cache and the DQL to SQL
-    conversions with the query cache. These 2 caches require only an
-    absolute minimum of memory yet they heavily improve the runtime
-    performance of Doctrine. The recommended cache driver to use with
-    Doctrine is `APC <http://www.php.net/apc>`_. APC provides you with
-    an opcode-cache (which is highly recommended anyway) and a very
-    fast in-memory cache storage that you can use for the metadata and
-    query caches as seen in the previous code snippet.
-
-Configuration Options
----------------------
-
-The following sections describe all the configuration options
-available on a ``Doctrine\ORM\Configuration`` instance.
-
-Proxy Directory (***REQUIRED***)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code-block:: php
-
-    <?php
-    $config->setProxyDir($dir);
-    $config->getProxyDir();
-
-Gets or sets the directory where Doctrine generates any proxy
-classes. For a detailed explanation on proxy classes and how they
-are used in Doctrine, refer to the "Proxy Objects" section further
-down.
-
-Proxy Namespace (***REQUIRED***)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code-block:: php
-
-    <?php
-    $config->setProxyNamespace($namespace);
-    $config->getProxyNamespace();
-
-Gets or sets the namespace to use for generated proxy classes. For
-a detailed explanation on proxy classes and how they are used in
-Doctrine, refer to the "Proxy Objects" section further down.
-
-Metadata Driver (***REQUIRED***)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code-block:: php
-
-    <?php
-    $config->setMetadataDriverImpl($driver);
-    $config->getMetadataDriverImpl();
-
-Gets or sets the metadata driver implementation that is used by
-Doctrine to acquire the object-relational metadata for your
-classes.
-
-There are currently 4 available implementations:
-
-
--  ``Doctrine\ORM\Mapping\Driver\AnnotationDriver``
--  ``Doctrine\ORM\Mapping\Driver\XmlDriver``
--  ``Doctrine\ORM\Mapping\Driver\YamlDriver``
--  ``Doctrine\ORM\Mapping\Driver\DriverChain``
-
-Throughout the most part of this manual the AnnotationDriver is
-used in the examples. For information on the usage of the XmlDriver
-or YamlDriver please refer to the dedicated chapters
-``XML Mapping`` and ``YAML Mapping``.
-
-The annotation driver can be configured with a factory method on
-the ``Doctrine\ORM\Configuration``:
-
-.. code-block:: php
-
-    <?php
-    $driverImpl = $config->newDefaultAnnotationDriver('/path/to/lib/MyProject/Entities');
-    $config->setMetadataDriverImpl($driverImpl);
-
-The path information to the entities is required for the annotation
-driver, because otherwise mass-operations on all entities through
-the console could not work correctly. All of metadata drivers
-accept either a single directory as a string or an array of
-directories. With this feature a single driver can support multiple
-directories of Entities.
-
-Metadata Cache (***RECOMMENDED***)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code-block:: php
-
-    <?php
-    $config->setMetadataCacheImpl($cache);
-    $config->getMetadataCacheImpl();
-
-Gets or sets the cache implementation to use for caching metadata
-information, that is, all the information you supply via
-annotations, xml or yaml, so that they do not need to be parsed and
-loaded from scratch on every single request which is a waste of
-resources. The cache implementation must implement the
-``Doctrine\Common\Cache\Cache`` interface.
-
-Usage of a metadata cache is highly recommended.
-
-The recommended implementations for production are:
-
-
--  ``Doctrine\Common\Cache\ApcCache``
--  ``Doctrine\Common\Cache\ApcuCache``
--  ``Doctrine\Common\Cache\MemcacheCache``
--  ``Doctrine\Common\Cache\XcacheCache``
--  ``Doctrine\Common\Cache\RedisCache``
-
-For development you should use the
-``Doctrine\Common\Cache\ArrayCache`` which only caches data on a
-per-request basis.
-
-Query Cache (***RECOMMENDED***)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code-block:: php
-
-    <?php
-    $config->setQueryCacheImpl($cache);
-    $config->getQueryCacheImpl();
-
-Gets or sets the cache implementation to use for caching DQL
-queries, that is, the result of a DQL parsing process that includes
-the final SQL as well as meta information about how to process the
-SQL result set of a query. Note that the query cache does not
-affect query results. You do not get stale data. This is a pure
-optimization cache without any negative side-effects (except some
-minimal memory usage in your cache).
-
-Usage of a query cache is highly recommended.
-
-The recommended implementations for production are:
-
-
--  ``Doctrine\Common\Cache\ApcCache``
--  ``Doctrine\Common\Cache\ApcuCache``
--  ``Doctrine\Common\Cache\MemcacheCache``
--  ``Doctrine\Common\Cache\XcacheCache``
--  ``Doctrine\Common\Cache\RedisCache``
-
-For development you should use the
-``Doctrine\Common\Cache\ArrayCache`` which only caches data on a
-per-request basis.
-
-SQL Logger (***Optional***)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code-block:: php
-
-    <?php
-    $config->setSQLLogger($logger);
-    $config->getSQLLogger();
-
-Gets or sets the logger to use for logging all SQL statements
-executed by Doctrine. The logger class must implement the
-``Doctrine\DBAL\Logging\SQLLogger`` interface. A simple default
-implementation that logs to the standard output using ``echo`` and
-``var_dump`` can be found at
-``Doctrine\DBAL\Logging\EchoSQLLogger``.
-
-Auto-generating Proxy Classes (***OPTIONAL***)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Proxy classes can either be generated manually through the Doctrine
-Console or automatically at runtime by Doctrine. The configuration
-option that controls this behavior is:
-
-.. code-block:: php
-
-    <?php
-    $config->setAutoGenerateProxyClasses($mode);
-
-Possible values for ``$mode`` are:
-
--  ``Doctrine\Common\Proxy\AbstractProxyFactory::AUTOGENERATE_NEVER``
-
-Never autogenerate a proxy. You will need to generate the proxies
-manually, for this use the Doctrine Console like so:
-
-.. code-block:: php
-
-    $ ./doctrine orm:generate-proxies
-
-When you do this in a development environment,
-be aware that you may get class/file not found errors if certain proxies
-are not yet generated. You may also get failing lazy-loads if new
-methods were added to the entity class that are not yet in the proxy class.
-In such a case, simply use the Doctrine Console to (re)generate the
-proxy classes.
-
--  ``Doctrine\Common\Proxy\AbstractProxyFactory::AUTOGENERATE_ALWAYS``
-
-Always generates a new proxy in every request and writes it to disk.
-
--  ``Doctrine\Common\Proxy\AbstractProxyFactory::AUTOGENERATE_FILE_NOT_EXISTS``
-
-Generate the proxy class when the proxy file does not exist.
-This strategy causes a file exists call whenever any proxy is
-used the first time in a request.
-
--  ``Doctrine\Common\Proxy\AbstractProxyFactory::AUTOGENERATE_EVAL``
-
-Generate the proxy classes and evaluate them on the fly via eval(),
-avoiding writing the proxies to disk.
-This strategy is only sane for development.
-
-In a production environment, it is highly recommended to use
-AUTOGENERATE_NEVER to allow for optimal performances. The other
-options are interesting in development environment.
-
-``setAutoGenerateProxyClasses`` can accept a boolean
-value. This is still possible, ``FALSE`` being equivalent to
-AUTOGENERATE_NEVER and ``TRUE`` to AUTOGENERATE_ALWAYS.
-
-Development vs Production Configuration
----------------------------------------
-
-You should code your Doctrine2 bootstrapping with two different
-runtime models in mind. There are some serious benefits of using
-APC or Memcache in production. In development however this will
-frequently give you fatal errors, when you change your entities and
-the cache still keeps the outdated metadata. That is why we
-recommend the ``ArrayCache`` for development.
-
-Furthermore you should have the Auto-generating Proxy Classes
-option to true in development and to false in production. If this
-option is set to ``TRUE`` it can seriously hurt your script
-performance if several proxy classes are re-generated during script
-execution. Filesystem calls of that magnitude can even slower than
-all the database queries Doctrine issues. Additionally writing a
-proxy sets an exclusive file lock which can cause serious
-performance bottlenecks in systems with regular concurrent
-requests.
-
-Connection Options
-------------------
-
-The ``$connectionOptions`` passed as the first argument to
-``EntityManager::create()`` has to be either an array or an
-instance of ``Doctrine\DBAL\Connection``. If an array is passed it
-is directly passed along to the DBAL Factory
-``Doctrine\DBAL\DriverManager::getConnection()``. The DBAL
-configuration is explained in the
-`DBAL section <https://www.doctrine-project.org/projects/doctrine-dbal/en/current/reference/configuration.html>`_.
-
-Proxy Objects
--------------
-
-A proxy object is an object that is put in place or used instead of
-the "real" object. A proxy object can add behavior to the object
-being proxied without that object being aware of it. In ORM,
-proxy objects are used to realize several features but mainly for
-transparent lazy-loading.
-
-Proxy objects with their lazy-loading facilities help to keep the
-subset of objects that are already in memory connected to the rest
-of the objects. This is an essential property as without it there
-would always be fragile partial objects at the outer edges of your
-object graph.
-
-Doctrine ORM implements a variant of the proxy pattern where it
-generates classes that extend your entity classes and adds
-lazy-loading capabilities to them. Doctrine can then give you an
-instance of such a proxy class whenever you request an object of
-the class being proxied. This happens in two situations:
-
-Reference Proxies
-~~~~~~~~~~~~~~~~~
-
-The method ``EntityManager#getReference($entityName, $identifier)``
-lets you obtain a reference to an entity for which the identifier
-is known, without loading that entity from the database. This is
-useful, for example, as a performance enhancement, when you want to
-establish an association to an entity for which you have the
-identifier. You could simply do this:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager, $cart instanceof MyProject\Model\Cart
-    // $itemId comes from somewhere, probably a request parameter
-    $item = $em->getReference('MyProject\Model\Item', $itemId);
-    $cart->addItem($item);
-
-Here, we added an Item to a Cart without loading the Item from the
-database. If you invoke any method on the Item instance, it would
-fully initialize its state transparently from the database. Here
-$item is actually an instance of the proxy class that was generated
-for the Item class but your code does not need to care. In fact it
-**should not care**. Proxy objects should be transparent to your
-code.
-
-Association proxies
-~~~~~~~~~~~~~~~~~~~
-
-The second most important situation where Doctrine uses proxy
-objects is when querying for objects. Whenever you query for an
-object that has a single-valued association to another object that
-is configured LAZY, without joining that association in the same
-query, Doctrine puts proxy objects in place where normally the
-associated object would be. Just like other proxies it will
-transparently initialize itself on first access.
-
-.. note::
-
-    Joining an association in a DQL or native query
-    essentially means eager loading of that association in that query.
-    This will override the 'fetch' option specified in the mapping for
-    that association, but only for that query.
-
-
-Generating Proxy classes
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-In a production environment, it is highly recommended to use
-``AUTOGENERATE_NEVER`` to allow for optimal performances.
-However you will be required to generate the proxies manually
-using the Doctrine Console:
-
-.. code-block:: php
-
-    $ ./doctrine orm:generate-proxies
-
-The other options are interesting in development environment:
-
-- ``AUTOGENERATE_ALWAYS`` will require you to create and configure
-  a proxy directory. Proxies will be generated and written to file
-  on each request, so any modification to your code will be acknowledged.
-
-- ``AUTOGENERATE_FILE_NOT_EXISTS`` will not overwrite an existing
-  proxy file. If your code changes, you will need to regenerate the
-  proxies manually.
-
-- ``AUTOGENERATE_EVAL`` will regenerate each proxy on each request,
-  but without writing them to disk.
-
-Autoloading Proxies
--------------------
-
-When you deserialize proxy objects from the session or any other storage
-it is necessary to have an autoloading mechanism in place for these classes.
-For implementation reasons Proxy class names are not PSR-0 compliant. This
-means that you have to register a special autoloader for these classes:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Common\Proxy\Autoloader;
-
-    $proxyDir = "/path/to/proxies";
-    $proxyNamespace = "MyProxies";
-
-    Autoloader::register($proxyDir, $proxyNamespace);
-
-If you want to execute additional logic to intercept the proxy file not found
-state you can pass a closure as the third argument. It will be called with
-the arguments proxydir, namespace and className when the proxy file could not
-be found.
-
-Multiple Metadata Sources
--------------------------
-
-When using different components using Doctrine ORM you may end up
-with them using two different metadata drivers, for example XML and
-YAML. You can use the DriverChain Metadata implementations to
-aggregate these drivers based on namespaces:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Mapping\Driver\DriverChain;
-
-    $chain = new DriverChain();
-    $chain->addDriver($xmlDriver, 'Doctrine\Tests\Models\Company');
-    $chain->addDriver($yamlDriver, 'Doctrine\Tests\ORM\Mapping');
-
-Based on the namespace of the entity the loading of entities is
-delegated to the appropriate driver. The chain semantics come from
-the fact that the driver loops through all namespaces and matches
-the entity class name against the namespace using a
-``strpos() === 0`` call. This means you need to order the drivers
-correctly if sub-namespaces use different metadata driver
-implementations.
-
-
-Default Repository (***OPTIONAL***)
------------------------------------
-
-Specifies the FQCN of a subclass of the EntityRepository.
-That will be available for all entities without a custom repository class.
-
-.. code-block:: php
-
-    <?php
-    $config->setDefaultRepositoryClassName($fqcn);
-    $config->getDefaultRepositoryClassName();
-
-The default value is ``Doctrine\ORM\EntityRepository``.
-Any repository class must be a subclass of EntityRepository otherwise you got an ORMException
-
-Setting up the Console
-----------------------
-
-Doctrine uses the Symfony Console component for generating the command
-line interface. You can take a look at the ``vendor/bin/doctrine.php``
-script and the ``Doctrine\ORM\Tools\Console\ConsoleRunner`` command
-for inspiration how to setup the cli.
-
-In general the required code looks like this:
-
-.. code-block:: php
-
-    <?php
-    $cli = new Application('Doctrine Command Line Interface', \Doctrine\ORM\Version::VERSION);
-    $cli->setCatchExceptions(true);
-    $cli->setHelperSet($helperSet);
-    Doctrine\ORM\Tools\Console\ConsoleRunner::addCommands($cli);
-    $cli->run();

-Architecture
-============
-
-This chapter gives an overview of the overall architecture,
-terminology and constraints of Doctrine ORM. It is recommended to
-read this chapter carefully.
-
-Using an Object-Relational Mapper
----------------------------------
-
-As the term ORM already hints at, Doctrine ORM aims to simplify the
-translation between database rows and the PHP object model. The
-primary use case for Doctrine are therefore applications that
-utilize the Object-Oriented Programming Paradigm. For applications
-that do not primarily work with objects Doctrine ORM is not suited very
-well.
-
-Requirements
-------------
-
-Doctrine ORM requires a minimum of PHP 7.1. For greatly improved
-performance it is also recommended that you use APC with PHP.
-
-Doctrine ORM Packages
--------------------
-
-Doctrine ORM is divided into three main packages.
-
--  Common
--  DBAL (includes Common)
--  ORM (includes DBAL+Common)
-
-This manual mainly covers the ORM package, sometimes touching parts
-of the underlying DBAL and Common packages. The Doctrine code base
-is split in to these packages for a few reasons and they are to...
-
-
--  ...make things more maintainable and decoupled
--  ...allow you to use the code in Doctrine Common without the ORM
-   or DBAL
--  ...allow you to use the DBAL without the ORM
-
-The Common Package
-~~~~~~~~~~~~~~~~~~
-
-The Common package contains highly reusable components that have no
-dependencies beyond the package itself (and PHP, of course). The
-root namespace of the Common package is ``Doctrine\Common``.
-
-The DBAL Package
-~~~~~~~~~~~~~~~~
-
-The DBAL package contains an enhanced database abstraction layer on
-top of PDO but is not strongly bound to PDO. The purpose of this
-layer is to provide a single API that bridges most of the
-differences between the different RDBMS vendors. The root namespace
-of the DBAL package is ``Doctrine\DBAL``.
-
-The ORM Package
-~~~~~~~~~~~~~~~
-
-The ORM package contains the object-relational mapping toolkit that
-provides transparent relational persistence for plain PHP objects.
-The root namespace of the ORM package is ``Doctrine\ORM``.
-
-Terminology
------------
-
-Entities
-~~~~~~~~
-
-An entity is a lightweight, persistent domain object. An entity can
-be any regular PHP class observing the following restrictions:
-
-
--  An entity class must not be final or contain final methods.
--  All persistent properties/field of any entity class should
-   always be private or protected, otherwise lazy-loading might not
-   work as expected. In case you serialize entities (for example Session)
-   properties should be protected (See Serialize section below).
--  An entity class must not implement ``__clone`` or
-   :doc:`do so safely <../cookbook/implementing-wakeup-or-clone>`.
--  An entity class must not implement ``__wakeup`` or
-   :doc:`do so safely <../cookbook/implementing-wakeup-or-clone>`.
-   Also consider implementing
-   `Serializable <http://php.net/manual/en/class.serializable.php>`_
-   instead.
--  Any two entity classes in a class hierarchy that inherit
-   directly or indirectly from one another must not have a mapped
-   property with the same name. That is, if B inherits from A then B
-   must not have a mapped field with the same name as an already
-   mapped field that is inherited from A.
--  An entity cannot make use of func_get_args() to implement variable parameters.
-   Generated proxies do not support this for performance reasons and your code might
-   actually fail to work when violating this restriction.
-
-Entities support inheritance, polymorphic associations, and
-polymorphic queries. Both abstract and concrete classes can be
-entities. Entities may extend non-entity classes as well as entity
-classes, and non-entity classes may extend entity classes.
-
-.. note::
-
-    The constructor of an entity is only ever invoked when
-    *you* construct a new instance with the *new* keyword. Doctrine
-    never calls entity constructors, thus you are free to use them as
-    you wish and even have it require arguments of any type.
-
-
-Entity states
-~~~~~~~~~~~~~
-
-An entity instance can be characterized as being NEW, MANAGED,
-DETACHED or REMOVED.
-
-
--  A NEW entity instance has no persistent identity, and is not yet
-   associated with an EntityManager and a UnitOfWork (i.e. those just
-   created with the "new" operator).
--  A MANAGED entity instance is an instance with a persistent
-   identity that is associated with an EntityManager and whose
-   persistence is thus managed.
--  A DETACHED entity instance is an instance with a persistent
-   identity that is not (or no longer) associated with an
-   EntityManager and a UnitOfWork.
--  A REMOVED entity instance is an instance with a persistent
-   identity, associated with an EntityManager, that will be removed
-   from the database upon transaction commit.
-
-.. _architecture_persistent_fields:
-
-Persistent fields
-~~~~~~~~~~~~~~~~~
-
-The persistent state of an entity is represented by instance
-variables. An instance variable must be directly accessed only from
-within the methods of the entity by the entity instance itself.
-Instance variables must not be accessed by clients of the entity.
-The state of the entity is available to clients only through the
-entity’s methods, i.e. accessor methods (getter/setter methods) or
-other business methods.
-
-Collection-valued persistent fields and properties must be defined
-in terms of the ``Doctrine\Common\Collections\Collection``
-interface. The collection implementation type may be used by the
-application to initialize fields or properties before the entity is
-made persistent. Once the entity becomes managed (or detached),
-subsequent access must be through the interface type.
-
-Serializing entities
-~~~~~~~~~~~~~~~~~~~~
-
-Serializing entities can be problematic and is not really
-recommended, at least not as long as an entity instance still holds
-references to proxy objects or is still managed by an
-EntityManager. If you intend to serialize (and unserialize) entity
-instances that still hold references to proxy objects you may run
-into problems with private properties because of technical
-limitations. Proxy objects implement ``__sleep`` and it is not
-possible for ``__sleep`` to return names of private properties in
-parent classes. On the other hand it is not a solution for proxy
-objects to implement ``Serializable`` because Serializable does not
-work well with any potential cyclic object references (at least we
-did not find a way yet, if you did, please contact us).
-
-The EntityManager
-~~~~~~~~~~~~~~~~~
-
-The ``EntityManager`` class is a central access point to the
-functionality provided by Doctrine ORM. The ``EntityManager`` API is
-used to manage the persistence of your objects and to query for
-persistent objects.
-
-Transactional write-behind
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-An ``EntityManager`` and the underlying ``UnitOfWork`` employ a
-strategy called "transactional write-behind" that delays the
-execution of SQL statements in order to execute them in the most
-efficient way and to execute them at the end of a transaction so
-that all write locks are quickly released. You should see Doctrine
-as a tool to synchronize your in-memory objects with the database
-in well defined units of work. Work with your objects and modify
-them as usual and when you're done call ``EntityManager#flush()``
-to make your changes persistent.
-
-The Unit of Work
-~~~~~~~~~~~~~~~~
-
-Internally an ``EntityManager`` uses a ``UnitOfWork``, which is a
-typical implementation of the
-`Unit of Work pattern <http://martinfowler.com/eaaCatalog/unitOfWork.html>`_,
-to keep track of all the things that need to be done the next time
-``flush`` is invoked. You usually do not directly interact with a
-``UnitOfWork`` but with the ``EntityManager`` instead.

-Basic Mapping
-=============
-
-This guide explains the basic mapping of entities and properties.
-After working through this guide you should know:
-
-- How to create PHP objects that can be saved to the database with Doctrine;
-- How to configure the mapping between columns on tables and properties on
-  entities;
-- What Doctrine mapping types are;
-- Defining primary keys and how identifiers are generated by Doctrine;
-- How quoting of reserved symbols works in Doctrine.
-
-Mapping of associations will be covered in the next chapter on
-:doc:`Association Mapping <association-mapping>`.
-
-Guide Assumptions
------------------
-
-You should have already :doc:`installed and configure <configuration>`
-Doctrine.
-
-Creating Classes for the Database
----------------------------------
-
-Every PHP object that you want to save in the database using Doctrine
-is called an "Entity". The term "Entity" describes objects
-that have an identity over many independent requests. This identity is
-usually achieved by assigning a unique identifier to an entity.
-In this tutorial the following ``Message`` PHP class will serve as the
-example Entity:
-
-.. code-block:: php
-
-    <?php
-    class Message
-    {
-        private $id;
-        private $text;
-        private $postedAt;
-    }
-
-Because Doctrine is a generic library, it only knows about your
-entities because you will describe their existence and structure using
-mapping metadata, which is configuration that tells Doctrine how your
-entity should be stored in the database. The documentation will often
-speak of "mapping something", which means writing the mapping metadata
-that describes your entity.
-
-Doctrine provides several different ways to specify object-relational
-mapping metadata:
-
--  :doc:`Docblock Annotations <annotations-reference>`
--  :doc:`XML <xml-mapping>`
--  :doc:`YAML <yaml-mapping>`
--  :doc:`PHP code <php-mapping>`
-
-This manual will usually show mapping metadata via docblock annotations, though
-many examples also show the equivalent configuration in YAML and XML.
-
-.. note::
-
-    All metadata drivers perform equally. Once the metadata of a class has been
-    read from the source (annotations, xml or yaml) it is stored in an instance
-    of the ``Doctrine\ORM\Mapping\ClassMetadata`` class and these instances are
-    stored in the metadata cache.  If you're not using a metadata cache (not
-    recommended!) then the XML driver is the fastest.
-
-Marking our ``Message`` class as an entity for Doctrine is straightforward:
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        /** @Entity */
-        class Message
-        {
-            //...
-        }
-
-    .. code-block:: xml
-
-        <doctrine-mapping>
-          <entity name="Message">
-              <!-- ... -->
-          </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        Message:
-          type: entity
-          # ...
-
-With no additional information, Doctrine expects the entity to be saved
-into a table with the same name as the class in our case ``Message``.
-You can change this by configuring information about the table:
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        /**
-         * @Entity
-         * @Table(name="message")
-         */
-        class Message
-        {
-            //...
-        }
-
-    .. code-block:: xml
-
-        <doctrine-mapping>
-          <entity name="Message" table="message">
-              <!-- ... -->
-          </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        Message:
-          type: entity
-          table: message
-          # ...
-
-Now the class ``Message`` will be saved and fetched from the table ``message``.
-
-Property Mapping
-----------------
-
-The next step after marking a PHP class as an entity is mapping its properties
-to columns in a table.
-
-To configure a property use the ``@Column`` docblock annotation. The ``type``
-attribute specifies the :ref:`Doctrine Mapping Type <reference-mapping-types>`
-to use for the field. If the type is not specified, ``string`` is used as the
-default.
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        /** @Entity */
-        class Message
-        {
-            /** @Column(type="integer") */
-            private $id;
-            /** @Column(length=140) */
-            private $text;
-            /** @Column(type="datetime", name="posted_at") */
-            private $postedAt;
-        }
-
-    .. code-block:: xml
-
-        <doctrine-mapping>
-          <entity name="Message">
-            <field name="id" type="integer" />
-            <field name="text" length="140" />
-            <field name="postedAt" column="posted_at" type="datetime" />
-          </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        Message:
-          type: entity
-          fields:
-            id:
-              type: integer
-            text:
-              length: 140
-            postedAt:
-              type: datetime
-              column: posted_at
-
-When we don't explicitly specify a column name via the ``name`` option, Doctrine
-assumes the field name is also the column name. This means that:
-
-* the ``id`` property will map to the column ``id`` using the type ``integer``;
-* the ``text`` property will map to the column ``text`` with the default mapping type ``string``;
-* the ``postedAt`` property will map to the ``posted_at`` column with the ``datetime`` type.
-
-The Column annotation has some more attributes. Here is a complete
-list:
-
-- ``type``: (optional, defaults to 'string') The mapping type to
-  use for the column.
-- ``name``: (optional, defaults to field name) The name of the
-  column in the database.
-- ``length``: (optional, default 255) The length of the column in
-  the database. (Applies only if a string-valued column is used).
-- ``unique``: (optional, default FALSE) Whether the column is a
-  unique key.
-- ``nullable``: (optional, default FALSE) Whether the database
-  column is nullable.
-- ``precision``: (optional, default 0) The precision for a decimal
-  (exact numeric) column (applies only for decimal column),
-  which is the maximum number of digits that are stored for the values.
-- ``scale``: (optional, default 0) The scale for a decimal (exact
-  numeric) column (applies only for decimal column), which represents
-  the number of digits to the right of the decimal point and must
-  not be greater than *precision*.
-- ``columnDefinition``: (optional) Allows to define a custom
-  DDL snippet that is used to create the column. Warning: This normally
-  confuses the SchemaTool to always detect the column as changed.
-- ``options``: (optional) Key-value pairs of options that get passed
-  to the underlying database platform when generating DDL statements.
-
-.. _reference-mapping-types:
-
-Doctrine Mapping Types
-----------------------
-
-The ``type`` option used in the ``@Column`` accepts any of the existing
-Doctrine types or even your own custom types. A Doctrine type defines
-the conversion between PHP and SQL types, independent from the database vendor
-you are using. All Mapping Types that ship with Doctrine are fully portable
-between the supported database systems.
-
-As an example, the Doctrine Mapping Type ``string`` defines the
-mapping from a PHP string to a SQL VARCHAR (or VARCHAR2 etc.
-depending on the RDBMS brand). Here is a quick overview of the
-built-in mapping types:
-
--  ``string``: Type that maps a SQL VARCHAR to a PHP string.
--  ``integer``: Type that maps a SQL INT to a PHP integer.
--  ``smallint``: Type that maps a database SMALLINT to a PHP
-   integer.
--  ``bigint``: Type that maps a database BIGINT to a PHP string.
--  ``boolean``: Type that maps a SQL boolean or equivalent (TINYINT) to a PHP boolean.
--  ``decimal``: Type that maps a SQL DECIMAL to a PHP string.
--  ``date``: Type that maps a SQL DATETIME to a PHP DateTime
-   object.
--  ``time``: Type that maps a SQL TIME to a PHP DateTime object.
--  ``datetime``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object.
--  ``datetimetz``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object with timezone.
--  ``text``: Type that maps a SQL CLOB to a PHP string.
--  ``object``: Type that maps a SQL CLOB to a PHP object using
-   ``serialize()`` and ``unserialize()``
--  ``array``: Type that maps a SQL CLOB to a PHP array using
-   ``serialize()`` and ``unserialize()``
--  ``simple_array``: Type that maps a SQL CLOB to a PHP array using
-   ``implode()`` and ``explode()``, with a comma as delimiter. *IMPORTANT*
-   Only use this type if you are sure that your values cannot contain a ",".
--  ``json_array``: Type that maps a SQL CLOB to a PHP array using
-   ``json_encode()`` and ``json_decode()``
--  ``float``: Type that maps a SQL Float (Double Precision) to a
-   PHP double. *IMPORTANT*: Works only with locale settings that use
-   decimal points as separator.
--  ``guid``: Type that maps a database GUID/UUID to a PHP string. Defaults to
-   varchar but uses a specific type if the platform supports it.
--  ``blob``: Type that maps a SQL BLOB to a PHP resource stream
-
-A cookbook article shows how to define :doc:`your own custom mapping types
-<../cookbook/custom-mapping-types>`.
-
-.. note::
-
-    DateTime and Object types are compared by reference, not by value. Doctrine
-    updates this values if the reference changes and therefore behaves as if
-    these objects are immutable value objects.
-
-.. warning::
-
-    All Date types assume that you are exclusively using the default timezone
-    set by `date_default_timezone_set() <http://php.net/manual/en/function.date-default-timezone-set.php>`_
-    or by the php.ini configuration ``date.timezone``. Working with
-    different timezones will cause troubles and unexpected behavior.
-
-    If you need specific timezone handling you have to handle this
-    in your domain, converting all the values back and forth from UTC.
-    There is also a :doc:`cookbook entry <../cookbook/working-with-datetime>`
-    on working with datetimes that gives hints for implementing
-    multi timezone applications.
-
-Identifiers / Primary Keys
---------------------------
-
-Every entity class must have an identifier/primary key. You can select
-the field that serves as the identifier with the ``@Id``
-annotation.
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        class Message
-        {
-            /**
-             * @Id
-             * @Column(type="integer")
-             * @GeneratedValue
-             */
-            private $id;
-            //...
-        }
-
-    .. code-block:: xml
-
-        <doctrine-mapping>
-          <entity name="Message">
-            <id name="id" type="integer">
-                <generator strategy="AUTO" />
-            </id>
-            <!-- -->
-          </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        Message:
-          type: entity
-          id:
-            id:
-              type: integer
-              generator:
-                strategy: AUTO
-          fields:
-            # fields here
-
-In most cases using the automatic generator strategy (``@GeneratedValue``) is
-what you want. It defaults to the identifier generation mechanism your current
-database vendor prefers: AUTO_INCREMENT with MySQL, sequences with PostgreSQL 
-and Oracle and so on.
-
-Identifier Generation Strategies
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The previous example showed how to use the default identifier
-generation strategy without knowing the underlying database with
-the AUTO-detection strategy. It is also possible to specify the
-identifier generation strategy more explicitly, which allows you to
-make use of some additional features.
-
-Here is the list of possible generation strategies:
-
--  ``AUTO`` (default): Tells Doctrine to pick the strategy that is
-   preferred by the used database platform. The preferred strategies
-   are IDENTITY for MySQL, SQLite, MsSQL and SQL Anywhere and SEQUENCE
-   for Oracle and PostgreSQL. This strategy provides full portability.
--  ``SEQUENCE``: Tells Doctrine to use a database sequence for ID
-   generation. This strategy does currently not provide full
-   portability. Sequences are supported by Oracle, PostgreSql and
-   SQL Anywhere.
--  ``IDENTITY``: Tells Doctrine to use special identity columns in
-   the database that generate a value on insertion of a row. This
-   strategy does currently not provide full portability and is
-   supported by the following platforms: MySQL/SQLite/SQL Anywhere
-   (AUTO\_INCREMENT), MSSQL (IDENTITY) and PostgreSQL (SERIAL).
--  ``UUID``: Tells Doctrine to use the built-in Universally Unique Identifier
-   generator. This strategy provides full portability.
--  ``TABLE``: Tells Doctrine to use a separate table for ID
-   generation. This strategy provides full portability.
-   ***This strategy is not yet implemented!***
--  ``NONE``: Tells Doctrine that the identifiers are assigned (and
-   thus generated) by your code. The assignment must take place before
-   a new entity is passed to ``EntityManager#persist``. NONE is the
-   same as leaving off the @GeneratedValue entirely.
--  ``CUSTOM``: With this option, you can use the ``@CustomIdGenerator`` annotation.
-   It will allow you to pass a :doc:`class of your own to generate the identifiers.<_annref_customidgenerator>`
-
-Sequence Generator
-^^^^^^^^^^^^^^^^^^
-
-The Sequence Generator can currently be used in conjunction with
-Oracle or Postgres and allows some additional configuration options
-besides specifying the sequence's name:
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        class Message
-        {
-            /**
-             * @Id
-             * @GeneratedValue(strategy="SEQUENCE")
-             * @SequenceGenerator(sequenceName="message_seq", initialValue=1, allocationSize=100)
-             */
-            protected $id = null;
-            //...
-        }
-
-    .. code-block:: xml
-
-        <doctrine-mapping>
-          <entity name="Message">
-            <id name="id" type="integer">
-                <generator strategy="SEQUENCE" />
-                <sequence-generator sequence-name="message_seq" allocation-size="100" initial-value="1" />
-            </id>
-          </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        Message:
-          type: entity
-          id:
-            id:
-              type: integer
-              generator:
-                strategy: SEQUENCE
-              sequenceGenerator:
-                sequenceName: message_seq
-                allocationSize: 100
-                initialValue: 1
-
-The initial value specifies at which value the sequence should
-start.
-
-The allocationSize is a powerful feature to optimize INSERT
-performance of Doctrine. The allocationSize specifies by how much
-values the sequence is incremented whenever the next value is
-retrieved. If this is larger than 1 (one) Doctrine can generate
-identifier values for the allocationSizes amount of entities. In
-the above example with ``allocationSize=100`` Doctrine ORM would only
-need to access the sequence once to generate the identifiers for
-100 new entities.
-
-*The default allocationSize for a @SequenceGenerator is currently 10.*
-
-.. caution::
-
-    The allocationSize is detected by SchemaTool and
-    transformed into an "INCREMENT BY " clause in the CREATE SEQUENCE
-    statement. For a database schema created manually (and not
-    SchemaTool) you have to make sure that the allocationSize
-    configuration option is never larger than the actual sequences
-    INCREMENT BY value, otherwise you may get duplicate keys.
-
-
-.. note::
-
-    It is possible to use strategy="AUTO" and at the same time
-    specifying a @SequenceGenerator. In such a case, your custom
-    sequence settings are used in the case where the preferred strategy
-    of the underlying platform is SEQUENCE, such as for Oracle and
-    PostgreSQL.
-
-
-Composite Keys
-~~~~~~~~~~~~~~
-
-With Doctrine ORM you can use composite primary keys, using ``@Id`` on more then
-one column. Some restrictions exist opposed to using a single identifier in
-this case: The use of the ``@GeneratedValue`` annotation is not supported,
-which means you can only use composite keys if you generate the primary key
-values yourself before calling ``EntityManager#persist()`` on the entity.
-
-More details on composite primary keys are discussed in a :doc:`dedicated tutorial
-<../tutorials/composite-primary-keys>`.
-
-Quoting Reserved Words
-----------------------
-
-Sometimes it is necessary to quote a column or table name because of reserved
-word conflicts. Doctrine does not quote identifiers automatically, because it
-leads to more problems than it would solve. Quoting tables and column names
-needs to be done explicitly using ticks in the definition.
-
-.. code-block:: php
-
-    <?php
-    /** @Column(name="`number`", type="integer") */
-    private $number;
-
-Doctrine will then quote this column name in all SQL statements
-according to the used database platform.
-
-.. warning::
-
-    Identifier Quoting does not work for join column names or discriminator
-    column names unless you are using a custom ``QuoteStrategy``.
-
-.. _reference-basic-mapping-custom-mapping-types:
-
-For more control over column quoting the ``Doctrine\ORM\Mapping\QuoteStrategy`` interface
-was introduced in ORM. It is invoked for every column, table, alias and other
-SQL names. You can implement the QuoteStrategy and set it by calling
-``Doctrine\ORM\Configuration#setQuoteStrategy()``.
-
-The ANSI Quote Strategy was added, which assumes quoting is not necessary for any SQL name.
-You can use it with the following code:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Mapping\AnsiQuoteStrategy;
-
-    $configuration->setQuoteStrategy(new AnsiQuoteStrategy());

-Batch Processing
-================
-
-This chapter shows you how to accomplish bulk inserts, updates and
-deletes with Doctrine in an efficient way. The main problem with
-bulk operations is usually not to run out of memory and this is
-especially what the strategies presented here provide help with.
-
-.. warning::
-
-    An ORM tool is not primarily well-suited for mass
-    inserts, updates or deletions. Every RDBMS has its own, most
-    effective way of dealing with such operations and if the options
-    outlined below are not sufficient for your purposes we recommend
-    you use the tools for your particular RDBMS for these bulk
-    operations.
-
-
-.. note::
-
-    Having an SQL logger enabled when processing batches can have a serious impact on performance and resource usage.
-    To avoid that you should disable it in the DBAL configuration:
-.. code-block:: php
-
-    <?php
-    $em->getConnection()->getConfiguration()->setSQLLogger(null);
-
-Bulk Inserts
-------------
-
-Bulk inserts in Doctrine are best performed in batches, taking
-advantage of the transactional write-behind behavior of an
-``EntityManager``. The following code shows an example for
-inserting 10000 objects with a batch size of 20. You may need to
-experiment with the batch size to find the size that works best for
-you. Larger batch sizes mean more prepared statement reuse
-internally but also mean more work during ``flush``.
-
-.. code-block:: php
-
-    <?php
-    $batchSize = 20;
-    for ($i = 1; $i <= 10000; ++$i) {
-        $user = new CmsUser;
-        $user->setStatus('user');
-        $user->setUsername('user' . $i);
-        $user->setName('Mr.Smith-' . $i);
-        $em->persist($user);
-        if (($i % $batchSize) === 0) {
-            $em->flush();
-            $em->clear(); // Detaches all objects from Doctrine!
-        }
-    }
-    $em->flush(); //Persist objects that did not make up an entire batch
-    $em->clear();
-
-Bulk Updates
-------------
-
-There are 2 possibilities for bulk updates with Doctrine.
-
-DQL UPDATE
-~~~~~~~~~~
-
-The by far most efficient way for bulk updates is to use a DQL
-UPDATE query. Example:
-
-.. code-block:: php
-
-    <?php
-    $q = $em->createQuery('update MyProject\Model\Manager m set m.salary = m.salary * 0.9');
-    $numUpdated = $q->execute();
-
-Iterating results
-~~~~~~~~~~~~~~~~~
-
-An alternative solution for bulk updates is to use the
-``Query#toIterable()`` facility to iterate over the query results step
-by step instead of loading the whole result into memory at once.
-The following example shows how to do this, combining the iteration
-with the batching strategy that was already used for bulk inserts:
-
-.. code-block:: php
-
-    <?php
-    $batchSize = 20;
-    $i = 1;
-    $q = $em->createQuery('select u from MyProject\Model\User u');
-    foreach ($q->toIterable() as $user) {
-        $user->increaseCredit();
-        $user->calculateNewBonuses();
-        if (($i % $batchSize) === 0) {
-            $em->flush(); // Executes all updates.
-            $em->clear(); // Detaches all objects from Doctrine!
-        }
-        ++$i;
-    }
-    $em->flush();
-
-.. note::
-
-    Iterating results is not possible with queries that
-    fetch-join a collection-valued association. The nature of such SQL
-    result sets is not suitable for incremental hydration.
-
-.. note::
-
-    Results may be fully buffered by the database client/ connection allocating
-    additional memory not visible to the PHP process. For large sets this
-    may easily kill the process for no apparent reason.
-
-
-Bulk Deletes
-------------
-
-There are two possibilities for bulk deletes with Doctrine. You can
-either issue a single DQL DELETE query or you can iterate over
-results removing them one at a time.
-
-DQL DELETE
-~~~~~~~~~~
-
-The by far most efficient way for bulk deletes is to use a DQL
-DELETE query.
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    $q = $em->createQuery('delete from MyProject\Model\Manager m where m.salary > 100000');
-    $numDeleted = $q->execute();
-
-Iterating results
-~~~~~~~~~~~~~~~~~
-
-An alternative solution for bulk deletes is to use the
-``Query#toIterable()`` facility to iterate over the query results step
-by step instead of loading the whole result into memory at once.
-The following example shows how to do this:
-
-.. code-block:: php
-
-    <?php
-    $batchSize = 20;
-    $i = 1;
-    $q = $em->createQuery('select u from MyProject\Model\User u');
-    foreach($q->toIterable() as $row) {
-        $em->remove($row);
-        if (($i % $batchSize) === 0) {
-            $em->flush(); // Executes all deletions.
-            $em->clear(); // Detaches all objects from Doctrine!
-        }
-        ++$i;
-    }
-    $em->flush();
-
-.. note::
-
-    Iterating results is not possible with queries that
-    fetch-join a collection-valued association. The nature of such SQL
-    result sets is not suitable for incremental hydration.
-
-
-Iterating Large Results for Data-Processing
--------------------------------------------
-
-You can use the ``toIterable()`` method just to iterate over a large
-result and no UPDATE or DELETE intention. ``$query->toIterable()`` returns ``iterable``
-so you can process a large result without memory
-problems using the following approach:
-
-.. code-block:: php
-
-    <?php
-    $q = $this->_em->createQuery('select u from MyProject\Model\User u');
-    foreach ($q->toIterable() as $row) {
-        // do stuff with the data in the row
-
-        // detach from Doctrine, so that it can be Garbage-Collected immediately
-        $this->_em->detach($row[0]);
-    }
-
-.. note::
-
-    Iterating results is not possible with queries that
-    fetch-join a collection-valued association. The nature of such SQL
-    result sets is not suitable for incremental hydration.

-Best Practices
-==============
-
-The best practices mentioned here that affect database
-design generally refer to best practices when working with Doctrine
-and do not necessarily reflect best practices for database design
-in general.
-
-Constrain relationships as much as possible
--------------------------------------------
-
-It is important to constrain relationships as much as possible.
-This means:
-
-
--  Impose a traversal direction (avoid bidirectional associations
-   if possible)
--  Eliminate nonessential associations
-
-This has several benefits:
-
-
--  Reduced coupling in your domain model
--  Simpler code in your domain model (no need to maintain
-   bidirectionality properly)
--  Less work for Doctrine
-
-Avoid composite keys
---------------------
-
-Even though Doctrine fully supports composite keys it is best not
-to use them if possible. Composite keys require additional work by
-Doctrine and thus have a higher probability of errors.
-
-Use events judiciously
-----------------------
-
-The event system of Doctrine is great and fast. Even though making
-heavy use of events, especially lifecycle events, can have a
-negative impact on the performance of your application. Thus you
-should use events judiciously.
-
-Use cascades judiciously
-------------------------
-
-Automatic cascades of the persist/remove/merge/etc. operations are
-very handy but should be used wisely. Do NOT simply add all
-cascades to all associations. Think about which cascades actually
-do make sense for you for a particular association, given the
-scenarios it is most likely used in.
-
-Don't use special characters
-----------------------------
-
-Avoid using any non-ASCII characters in class, field, table or
-column names. Doctrine itself is not unicode-safe in many places
-and will not be until PHP itself is fully unicode-aware.
-
-Don't use identifier quoting
-----------------------------
-
-Identifier quoting is a workaround for using reserved words that
-often causes problems in edge cases. Do not use identifier quoting
-and avoid using reserved words as table or column names.
-
-Initialize collections in the constructor
------------------------------------------
-
-It is recommended best practice to initialize any business
-collections in entities in the constructor. Example:
-
-.. code-block:: php
-
-    <?php
-    namespace MyProject\Model;
-    use Doctrine\Common\Collections\ArrayCollection;
-    
-    class User {
-        private $addresses;
-        private $articles;
-    
-        public function __construct() {
-            $this->addresses = new ArrayCollection;
-            $this->articles = new ArrayCollection;
-        }
-    }
-
-Don't map foreign keys to fields in an entity
----------------------------------------------
-
-Foreign keys have no meaning whatsoever in an object model. Foreign
-keys are how a relational database establishes relationships. Your
-object model establishes relationships through object references.
-Thus mapping foreign keys to object fields heavily leaks details of
-the relational model into the object model, something you really
-should not do.
-
-Use explicit transaction demarcation
-------------------------------------
-
-While Doctrine will automatically wrap all DML operations in a
-transaction on flush(), it is considered best practice to
-explicitly set the transaction boundaries yourself. Otherwise every
-single query is wrapped in a small transaction (Yes, SELECT
-queries, too) since you can not talk to your database outside of a
-transaction. While such short transactions for read-only (SELECT)
-queries generally don't have any noticeable performance impact, it
-is still preferable to use fewer, well-defined transactions that
-are established through explicit transaction boundaries.

-Caching
-=======
-
-Doctrine provides cache drivers in the ``doctrine/cache`` package for some
-of the most popular caching implementations such as APCu, Memcache
-and Xcache. We also provide an ``ArrayCache`` driver which stores
-the data in a PHP array. Obviously, when using ``ArrayCache``, the 
-cache does not persist between requests, but this is useful for 
-testing in a development environment.
-
-Cache Drivers
--------------
-
-The cache drivers follow a simple interface that is defined in
-``Doctrine\Common\Cache\Cache``. All the cache drivers extend a
-base class ``Doctrine\Common\Cache\CacheProvider`` which implements
-this interface.
-
-The interface defines the following public methods for you to implement:
-
-
--  fetch($id) - Fetches an entry from the cache
--  contains($id) - Test if an entry exists in the cache
--  save($id, $data, $lifeTime = false) - Puts data into the cache for x seconds. 0 = infinite time
--  delete($id) - Deletes a cache entry
-
-Each driver extends the ``CacheProvider`` class which defines a few
-abstract protected methods that each of the drivers must
-implement:
-
-
--  doFetch($id)
--  doContains($id)
--  doSave($id, $data, $lifeTime = false)
--  doDelete($id)
-
-The public methods ``fetch()``, ``contains()`` etc. use the
-above protected methods which are implemented by the drivers. The
-code is organized this way so that the protected methods in the
-drivers do the raw interaction with the cache implementation and
-the ``CacheProvider`` can build custom functionality on top of
-these methods.
-
-This documentation does not cover every single cache driver included
-with Doctrine. For an up-to-date-list, see the
-`cache directory on GitHub <https://github.com/doctrine/cache/tree/master/lib/Doctrine/Common/Cache>`_.
-
-PhpFileCache
-~~~~~~~~~~~~
-
-The preferred cache driver for metadata and query caches is ``PhpFileCache``.
-This driver serializes cache items and writes them to a file. This allows for
-opcode caching to be used and provides high performance in most scenarios.
-
-In order to use the ``PhpFileCache`` driver it must be able to write to
-a directory.
-
-Below is an example of how to use the ``PhpFileCache`` driver by itself.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver = new \Doctrine\Common\Cache\PhpFileCache(
-        '/path/to/writable/directory'
-    );
-    $cacheDriver->save('cache_id', 'my_data');
-
-The PhpFileCache is not distributed across multiple machines if you are running
-your application in a distributed setup. This is ok for the metadata and query
-cache but is not a good approach for the result cache.
-
-Memcache
-~~~~~~~~
-
-In order to use the Memcache cache driver you must have it compiled
-and enabled in your php.ini. You can read about Memcache
-`on the PHP website <http://php.net/memcache>`_. It will
-give you a little background information about what it is and how
-you can use it as well as how to install it.
-
-Below is a simple example of how you could use the Memcache cache
-driver by itself.
-
-.. code-block:: php
-
-    <?php
-    $memcache = new Memcache();
-    $memcache->connect('memcache_host', 11211);
-    
-    $cacheDriver = new \Doctrine\Common\Cache\MemcacheCache();
-    $cacheDriver->setMemcache($memcache);
-    $cacheDriver->save('cache_id', 'my_data');
-
-Memcached
-~~~~~~~~~
-
-Memcached is a more recent and complete alternative extension to
-Memcache.
-
-In order to use the Memcached cache driver you must have it compiled
-and enabled in your php.ini. You can read about Memcached
-`on the PHP website <http://php.net/memcached>`_. It will
-give you a little background information about what it is and how
-you can use it as well as how to install it.
-
-Below is a simple example of how you could use the Memcached cache
-driver by itself.
-
-.. code-block:: php
-
-    <?php
-    $memcached = new Memcached();
-    $memcached->addServer('memcache_host', 11211);
-    
-    $cacheDriver = new \Doctrine\Common\Cache\MemcachedCache();
-    $cacheDriver->setMemcached($memcached);
-    $cacheDriver->save('cache_id', 'my_data');
-
-Redis
-~~~~~
-
-In order to use the Redis cache driver you must have it compiled
-and enabled in your php.ini. You can read about what Redis is
-`from here <http://redis.io/>`_. Also check
-`A PHP extension for Redis <https://github.com/nicolasff/phpredis/>`_ for how you can use
-and install the Redis PHP extension.
-
-Below is a simple example of how you could use the Redis cache
-driver by itself.
-
-.. code-block:: php
-
-    <?php
-    $redis = new Redis();
-    $redis->connect('redis_host', 6379);
-
-    $cacheDriver = new \Doctrine\Common\Cache\RedisCache();
-    $cacheDriver->setRedis($redis);
-    $cacheDriver->save('cache_id', 'my_data');
-
-Using Cache Drivers
--------------------
-
-In this section we'll describe how you can fully utilize the API of
-the cache drivers to save data to a cache, check if some cached data 
-exists, fetch the cached data and delete the cached data. We'll use the
-``ArrayCache`` implementation as our example here.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver = new \Doctrine\Common\Cache\ArrayCache();
-
-Saving
-~~~~~~
-
-Saving some data to the cache driver is as simple as using the
-``save()`` method.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver->save('cache_id', 'my_data');
-
-The ``save()`` method accepts three arguments which are described
-below:
-
-
--  ``$id`` - The cache id
--  ``$data`` - The cache entry/data.
--  ``$lifeTime`` - The lifetime. If != false, sets a specific
-   lifetime for this cache entry (null => infinite lifeTime).
-
-You can save any type of data whether it be a string, array,
-object, etc.
-
-.. code-block:: php
-
-    <?php
-    $array = array(
-        'key1' => 'value1',
-        'key2' => 'value2'
-    );
-    $cacheDriver->save('my_array', $array);
-
-Checking
-~~~~~~~~
-
-Checking whether cached data exists is very simple: just use the
-``contains()`` method. It accepts a single argument which is the ID
-of the cache entry.
-
-.. code-block:: php
-
-    <?php
-    if ($cacheDriver->contains('cache_id')) {
-        echo 'cache exists';
-    } else {
-        echo 'cache does not exist';
-    }
-
-Fetching
-~~~~~~~~
-
-Now if you want to retrieve some cache entry you can use the
-``fetch()`` method. It also accepts a single argument just like
-``contains()`` which is again the ID of the cache entry.
-
-.. code-block:: php
-
-    <?php
-    $array = $cacheDriver->fetch('my_array');
-
-Deleting
-~~~~~~~~
-
-As you might guess, deleting is just as easy as saving, checking
-and fetching. You can delete by an individual ID, or you can 
-delete all entries.
-
-By Cache ID
-^^^^^^^^^^^
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver->delete('my_array');
-
-All
-^^^
-
-If you simply want to delete all cache entries you can do so with
-the ``deleteAll()`` method.
-
-.. code-block:: php
-
-    <?php
-    $deleted = $cacheDriver->deleteAll();
-
-Namespaces
-~~~~~~~~~~
-
-If you heavily use caching in your application and use it in
-multiple parts of your application, or use it in different
-applications on the same server you may have issues with cache
-naming collisions. This can be worked around by using namespaces.
-You can set the namespace a cache driver should use by using the
-``setNamespace()`` method.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver->setNamespace('my_namespace_');
-
-.. _integrating-with-the-orm:
-
-Integrating with the ORM
-------------------------
-
-The Doctrine ORM package is tightly integrated with the cache
-drivers to allow you to improve the performance of various aspects of
-Doctrine by simply making some additional configurations and
-method calls.
-
-Query Cache
-~~~~~~~~~~~
-
-It is highly recommended that in a production environment you cache
-the transformation of a DQL query to its SQL counterpart. It
-doesn't make sense to do this parsing multiple times as it doesn't
-change unless you alter the DQL query.
-
-This can be done by configuring the query cache implementation to
-use on your ORM configuration.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver = new \Doctrine\Common\Cache\PhpFileCache(
-        '/path/to/writable/directory'
-    );
-    $config = new \Doctrine\ORM\Configuration();
-    $config->setQueryCacheImpl($cacheDriver);
-
-Result Cache
-~~~~~~~~~~~~
-
-The result cache can be used to cache the results of your queries
-so that we don't have to query the database or hydrate the data
-again after the first time. You just need to configure the result
-cache implementation.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver = new \Doctrine\Common\Cache\PhpFileCache(
-        '/path/to/writable/directory'
-    );
-    $config = new \Doctrine\ORM\Configuration();
-    $config->setResultCacheImpl($cacheDriver);
-
-Now when you're executing DQL queries you can configure them to use
-the result cache.
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery('select u from \Entities\User u');
-    $query->enableResultCache();
-
-You can also configure an individual query to use a different
-result cache driver.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver = new \Doctrine\Common\Cache\PhpFileCache(
-        '/path/to/writable/directory'
-    );
-    $query->setResultCacheDriver($cacheDriver);
-
-.. note::
-
-    Setting the result cache driver on the query will
-    automatically enable the result cache for the query. If you want to
-    disable it use ``disableResultCache()``.
-
-    ::
-
-        <?php
-        $query->disableResultCache();
-
-
-If you want to set the time the cache has to live you can use the
-``setResultCacheLifetime()`` method.
-
-.. code-block:: php
-
-    <?php
-    $query->setResultCacheLifetime(3600);
-
-The ID used to store the result set cache is a hash which is
-automatically generated for you if you don't set a custom ID
-yourself with the ``setResultCacheId()`` method.
-
-.. code-block:: php
-
-    <?php
-    $query->setResultCacheId('my_custom_id');
-
-You can also set the lifetime and cache ID by passing the values as
-the first and second argument to ``enableResultCache()``.
-
-.. code-block:: php
-
-    <?php
-    $query->enableResultCache(3600, 'my_custom_id');
-
-Metadata Cache
-~~~~~~~~~~~~~~
-
-Your class metadata can be parsed from a few different sources like
-YAML, XML, Annotations, etc. Instead of parsing this information on
-each request we should cache it using one of the cache drivers.
-
-Just like the query and result cache we need to configure it
-first.
-
-.. code-block:: php
-
-    <?php
-    $cacheDriver = new \Doctrine\Common\Cache\PhpFileCache(
-        '/path/to/writable/directory'
-    );
-    $config = new \Doctrine\ORM\Configuration();
-    $config->setMetadataCacheImpl($cacheDriver);
-
-Now the metadata information will only be parsed once and stored in
-the cache driver.
-
-Clearing the Cache
-------------------
-
-We've already shown you how you can use the API of the
-cache drivers to manually delete cache entries. For your
-convenience we offer command line tasks to help you with
-clearing the query, result and metadata cache.
-
-From the Doctrine command line you can run the following commands:
-
-To clear the query cache use the ``orm:clear-cache:query`` task.
-
-.. code-block:: php
-
-    $ ./doctrine orm:clear-cache:query
-
-To clear the metadata cache use the ``orm:clear-cache:metadata`` task.
-
-.. code-block:: php
-
-    $ ./doctrine orm:clear-cache:metadata
-
-To clear the result cache use the ``orm:clear-cache:result`` task.
-
-.. code-block:: php
-
-    $ ./doctrine orm:clear-cache:result
-
-All these tasks accept a ``--flush`` option to flush the entire
-contents of the cache instead of invalidating the entries.
-
-.. note::
-
-    None of these tasks will work with APC, APCu, or XCache drivers
-    because the memory that the cache is stored in is only accessible
-    to the webserver.
-
-Cache Chaining
---------------
-
-A common pattern is to use a static cache to store data that is
-requested many times in a single PHP request. Even though this data
-may be stored in a fast memory cache, often that cache is over a
-network link leading to sizable network traffic.
-
-The ChainCache class allows multiple caches to be registered at once.
-For example, a per-request ArrayCache can be used first, followed by
-a (relatively) slower MemcacheCache if the ArrayCache misses.
-ChainCache automatically handles pushing data up to faster caches in
-the chain and clearing data in the entire stack when it is deleted.
-
-A ChainCache takes a simple array of CacheProviders in the order that
-they should be used.
-
-.. code-block:: php
-
-    $arrayCache = new \Doctrine\Common\Cache\ArrayCache();
-    $memcache = new Memcache();
-    $memcache->connect('memcache_host', 11211);
-    $chainCache = new \Doctrine\Common\Cache\ChainCache([
-        $arrayCache,
-        $memcache,
-    ]);
-
-ChainCache itself extends the CacheProvider interface, so it is
-possible to create chains of chains. While this may seem like an easy
-way to build a simple high-availability cache, ChainCache does not
-implement any exception handling so using it as a high-availability
-mechanism is not recommended.
-
-Cache Slams
------------
-
-Something to be careful of when using the cache drivers is
-"cache slams". Imagine you have a heavily trafficked website with some
-code that checks for the existence of a cache record and if it does
-not exist it generates the information and saves it to the cache.
-Now, if 100 requests were issued all at the same time and each one
-sees the cache does not exist and they all try to insert the same
-cache entry it could lock up APC, Xcache, etc. and cause problems.
-Ways exist to work around this, like pre-populating your cache and
-not letting your users' requests populate the cache.
-
-You can read more about cache slams
-`in this blog post <http://notmysock.org/blog/php/user-cache-timebomb.html>`_.

-Change Tracking Policies
-========================
-
-Change tracking is the process of determining what has changed in
-managed entities since the last time they were synchronized with
-the database.
-
-Doctrine provides 3 different change tracking policies, each having
-its particular advantages and disadvantages. The change tracking
-policy can be defined on a per-class basis (or more precisely,
-per-hierarchy).
-
-Deferred Implicit
-~~~~~~~~~~~~~~~~~
-
-The deferred implicit policy is the default change tracking policy
-and the most convenient one. With this policy, Doctrine detects the
-changes by a property-by-property comparison at commit time and
-also detects changes to entities or new entities that are
-referenced by other managed entities ("persistence by
-reachability"). Although the most convenient policy, it can have
-negative effects on performance if you are dealing with large units
-of work (see "Understanding the Unit of Work"). Since Doctrine
-can't know what has changed, it needs to check all managed entities
-for changes every time you invoke EntityManager#flush(), making
-this operation rather costly.
-
-Deferred Explicit
-~~~~~~~~~~~~~~~~~
-
-The deferred explicit policy is similar to the deferred implicit
-policy in that it detects changes through a property-by-property
-comparison at commit time. The difference is that Doctrine ORM only
-considers entities that have been explicitly marked for change detection
-through a call to EntityManager#persist(entity) or through a save
-cascade. All other entities are skipped. This policy therefore
-gives improved performance for larger units of work while
-sacrificing the behavior of "automatic dirty checking".
-
-Therefore, flush() operations are potentially cheaper with this
-policy. The negative aspect this has is that if you have a rather
-large application and you pass your objects through several layers
-for processing purposes and business tasks you may need to track
-yourself which entities have changed on the way so you can pass
-them to EntityManager#persist().
-
-This policy can be configured as follows:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * @Entity
-     * @ChangeTrackingPolicy("DEFERRED_EXPLICIT")
-     */
-    class User
-    {
-        // ...
-    }
-
-Notify
-~~~~~~
-
-This policy is based on the assumption that the entities notify
-interested listeners of changes to their properties. For that
-purpose, a class that wants to use this policy needs to implement
-the ``NotifyPropertyChanged`` interface from the Doctrine
-namespace. As a guideline, such an implementation can look as
-follows:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Persistence\NotifyPropertyChanged,
-        Doctrine\Persistence\PropertyChangedListener;
-    
-    /**
-     * @Entity
-     * @ChangeTrackingPolicy("NOTIFY")
-     */
-    class MyEntity implements NotifyPropertyChanged
-    {
-        // ...
-    
-        private $_listeners = array();
-    
-        public function addPropertyChangedListener(PropertyChangedListener $listener)
-        {
-            $this->_listeners[] = $listener;
-        }
-    }
-
-Then, in each property setter of this class or derived classes, you
-need to notify all the ``PropertyChangedListener`` instances. As an
-example we add a convenience method on ``MyEntity`` that shows this
-behaviour:
-
-.. code-block:: php
-
-    <?php
-    // ...
-    
-    class MyEntity implements NotifyPropertyChanged
-    {
-        // ...
-    
-        protected function _onPropertyChanged($propName, $oldValue, $newValue)
-        {
-            if ($this->_listeners) {
-                foreach ($this->_listeners as $listener) {
-                    $listener->propertyChanged($this, $propName, $oldValue, $newValue);
-                }
-            }
-        }
-    
-        public function setData($data)
-        {
-            if ($data != $this->data) {
-                $this->_onPropertyChanged('data', $this->data, $data);
-                $this->data = $data;
-            }
-        }
-    }
-
-You have to invoke ``_onPropertyChanged`` inside every method that
-changes the persistent state of ``MyEntity``.
-
-The check whether the new value is different from the old one is
-not mandatory but recommended. That way you also have full control
-over when you consider a property changed.
-
-The negative point of this policy is obvious: You need implement an
-interface and write some plumbing code. But also note that we tried
-hard to keep this notification functionality abstract. Strictly
-speaking, it has nothing to do with the persistence layer and the
-Doctrine ORM or DBAL. You may find that property notification
-events come in handy in many other scenarios as well. As mentioned
-earlier, the ``Doctrine\Common`` namespace is not that evil and
-consists solely of very small classes and interfaces that have
-almost no external dependencies (none to the DBAL and none to the
-ORM) and that you can easily take with you should you want to swap
-out the persistence layer. This change tracking policy does not
-introduce a dependency on the Doctrine DBAL/ORM or the persistence
-layer.
-
-The positive point and main advantage of this policy is its
-effectiveness. It has the best performance characteristics of the 3
-policies with larger units of work and a flush() operation is very
-cheap when nothing has changed.

-Installation and Configuration
-==============================
-
-Doctrine can be installed with `Composer <https://getcomposer.org>`_.
-
-Define the following requirement in your ``composer.json`` file:
-
-::
-
-    {
-        "require": {
-            "doctrine/orm": "*"
-        }
-    }
-
-Then call ``composer install`` from your command line. If you don't know
-how Composer works, check out their `Getting Started <https://getcomposer.org/doc/00-intro.md>`_ to set up.
-
-Class loading
--------------
-
-Autoloading is taken care of by Composer. You just have to include the composer autoload file in your project:
-
-.. code-block:: php
-
-    <?php
-    // bootstrap.php
-    // Include Composer Autoload (relative to project root).
-    require_once "vendor/autoload.php";
-
-Obtaining an EntityManager
---------------------------
-
-Once you have prepared the class loading, you acquire an
-*EntityManager* instance. The EntityManager class is the primary
-access point to ORM functionality provided by Doctrine.
-
-.. code-block:: php
-
-    <?php
-    // bootstrap.php
-    require_once "vendor/autoload.php";
-
-    use Doctrine\ORM\Tools\Setup;
-    use Doctrine\ORM\EntityManager;
-
-    $paths = array("/path/to/entity-files");
-    $isDevMode = false;
-
-    // the connection configuration
-    $dbParams = array(
-        'driver'   => 'pdo_mysql',
-        'user'     => 'root',
-        'password' => '',
-        'dbname'   => 'foo',
-    );
-
-    $config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode);
-    $entityManager = EntityManager::create($dbParams, $config);
-
-Or if you prefer XML:
-
-.. code-block:: php
-
-    <?php
-    $paths = array("/path/to/xml-mappings");
-    $config = Setup::createXMLMetadataConfiguration($paths, $isDevMode);
-    $entityManager = EntityManager::create($dbParams, $config);
-
-Or if you prefer YAML:
-
-.. code-block:: php
-
-    <?php
-    $paths = array("/path/to/yml-mappings");
-    $config = Setup::createYAMLMetadataConfiguration($paths, $isDevMode);
-    $entityManager = EntityManager::create($dbParams, $config);
-
-.. note::
-    If you want to use yml mapping you should add yaml dependency to your `composer.json`:
-    
-    ::
-    
-        "symfony/yaml": "*"
-
-Inside the ``Setup`` methods several assumptions are made:
-
--  If `$isDevMode` is true caching is done in memory with the ``ArrayCache``. Proxy objects are recreated on every request.
--  If `$isDevMode` is false, check for Caches in the order APC, Xcache, Memcache (127.0.0.1:11211), Redis (127.0.0.1:6379) unless `$cache` is passed as fourth argument.
--  If `$isDevMode` is false, set then proxy classes have to be explicitly created through the command line.
--  If third argument `$proxyDir` is not set, use the systems temporary directory.
-
-If you want to configure Doctrine in more detail, take a look at the :doc:`Advanced Configuration <reference/advanced-configuration>` section.
-
-.. note::
-
-    You can learn more about the database connection configuration in the
-    `Doctrine DBAL connection configuration reference <http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html>`_.
-
-Setting up the Commandline Tool
--------------------------------
-
-Doctrine ships with a number of command line tools that are very helpful
-during development. You can call this command from the Composer binary
-directory:
-
-.. code-block:: sh
-
-    $ php vendor/bin/doctrine
-
-You need to register your applications EntityManager to the console tool
-to make use of the tasks by creating a ``cli-config.php`` file with the
-following content:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Tools\Console\ConsoleRunner;
-
-    // replace with file to your own project bootstrap
-    require_once 'bootstrap.php';
-
-    // replace with mechanism to retrieve EntityManager in your app
-    $entityManager = GetEntityManager();
-
-    return ConsoleRunner::createHelperSet($entityManager);

-Events
-======
-
-Doctrine ORM features a lightweight event system that is part of the
-Common package. Doctrine uses it to dispatch system events, mainly
-:ref:`lifecycle events <reference-events-lifecycle-events>`.
-You can also use it for your own custom events.
-
-The Event System
-----------------
-
-The event system is controlled by the ``EventManager``. It is the
-central point of Doctrine's event listener system. Listeners are
-registered on the manager and events are dispatched through the
-manager.
-
-.. code-block:: php
-
-    <?php
-    $evm = new EventManager();
-
-Now we can add some event listeners to the ``$evm``. Let's create a
-``TestEvent`` class to play around with.
-
-.. code-block:: php
-
-    <?php
-    class TestEvent
-    {
-        const preFoo = 'preFoo';
-        const postFoo = 'postFoo';
-
-        private $_evm;
-
-        public $preFooInvoked = false;
-        public $postFooInvoked = false;
-
-        public function __construct($evm)
-        {
-            $evm->addEventListener(array(self::preFoo, self::postFoo), $this);
-        }
-
-        public function preFoo(EventArgs $e)
-        {
-            $this->preFooInvoked = true;
-        }
-
-        public function postFoo(EventArgs $e)
-        {
-            $this->postFooInvoked = true;
-        }
-    }
-
-    // Create a new instance
-    $test = new TestEvent($evm);
-
-Events can be dispatched by using the ``dispatchEvent()`` method.
-
-.. code-block:: php
-
-    <?php
-    $evm->dispatchEvent(TestEvent::preFoo);
-    $evm->dispatchEvent(TestEvent::postFoo);
-
-You can easily remove a listener with the ``removeEventListener()``
-method.
-
-.. code-block:: php
-
-    <?php
-    $evm->removeEventListener(array(self::preFoo, self::postFoo), $this);
-
-The Doctrine ORM event system also has a simple concept of event
-subscribers. We can define a simple ``TestEventSubscriber`` class
-which implements the ``\Doctrine\Common\EventSubscriber`` interface
-and implements a ``getSubscribedEvents()`` method which returns an
-array of events it should be subscribed to.
-
-.. code-block:: php
-
-    <?php
-    class TestEventSubscriber implements \Doctrine\Common\EventSubscriber
-    {
-        public $preFooInvoked = false;
-
-        public function preFoo()
-        {
-            $this->preFooInvoked = true;
-        }
-
-        public function getSubscribedEvents()
-        {
-            return array(TestEvent::preFoo);
-        }
-    }
-
-    $eventSubscriber = new TestEventSubscriber();
-    $evm->addEventSubscriber($eventSubscriber);
-
-.. note::
-
-    The array to return in the ``getSubscribedEvents`` method is a simple array
-    with the values being the event names. The subscriber must have a method
-    that is named exactly like the event.
-
-Now when you dispatch an event, any event subscribers will be
-notified for that event.
-
-.. code-block:: php
-
-    <?php
-    $evm->dispatchEvent(TestEvent::preFoo);
-
-Now you can test the ``$eventSubscriber`` instance to see if the
-``preFoo()`` method was invoked.
-
-.. code-block:: php
-
-    <?php
-    if ($eventSubscriber->preFooInvoked) {
-        echo 'pre foo invoked!';
-    }
-
-Naming convention
-~~~~~~~~~~~~~~~~~
-
-Events being used with the Doctrine ORM EventManager are best named
-with camelcase and the value of the corresponding constant should
-be the name of the constant itself, even with spelling. This has
-several reasons:
-
-
--  It is easy to read.
--  Simplicity.
--  Each method within an EventSubscriber is named after the
-   corresponding constant's value. If the constant's name and value differ
-   it contradicts the intention of using the constant and makes your code
-   harder to maintain.
-
-An example for a correct notation can be found in the example
-``TestEvent`` above.
-
-.. _reference-events-lifecycle-events:
-
-Lifecycle Events
-----------------
-
-The ``EntityManager`` and ``UnitOfWork`` classes trigger a bunch of
-events during the life-time of their registered entities.
-
-
-
--  ``preRemove`` - The ``preRemove`` event occurs for a given entity
-   before the respective ``EntityManager`` remove operation for that
-   entity is executed.  It is not called for a DQL ``DELETE`` statement.
--  ``postRemove`` - The ``postRemove`` event occurs for an entity after the
-   entity has been deleted. It will be invoked after the database
-   delete operations. It is not called for a DQL ``DELETE`` statement.
--  ``prePersist`` - The ``prePersist`` event occurs for a given entity
-   before the respective ``EntityManager`` persist operation for that
-   entity is executed. It should be noted that this event is only triggered on
-   *initial* persist of an entity (i.e. it does not trigger on future updates).
--  ``postPersist`` - The ``postPersist`` event occurs for an entity after
-   the entity has been made persistent. It will be invoked after the
-   database insert operations. Generated primary key values are
-   available in the postPersist event.
--  ``preUpdate`` - The ``preUpdate`` event occurs before the database
-   update operations to entity data. It is not called for a DQL
-   ``UPDATE`` statement nor when the computed changeset is empty.
--  ``postUpdate`` - The ``postUpdate`` event occurs after the database
-   update operations to entity data. It is not called for a DQL
-   ``UPDATE`` statement.
--  ``postLoad`` - The postLoad event occurs for an entity after the
-   entity has been loaded into the current ``EntityManager`` from the
-   database or after the refresh operation has been applied to it.
--  ``loadClassMetadata`` - The ``loadClassMetadata`` event occurs after the
-   mapping metadata for a class has been loaded from a mapping source
-   (annotations/xml/yaml). This event is not a lifecycle callback.
--  ``onClassMetadataNotFound`` - Loading class metadata for a particular
-   requested class name failed. Manipulating the given event args instance
-   allows providing fallback metadata even when no actual metadata exists
-   or could be found. This event is not a lifecycle callback.
--  ``preFlush`` - The ``preFlush`` event occurs at the very beginning of
-   a flush operation.
--  ``onFlush`` - The ``onFlush`` event occurs after the change-sets of all
-   managed entities are computed. This event is not a lifecycle
-   callback.
--  ``postFlush`` - The ``postFlush`` event occurs at the end of a flush operation. This
-   event is not a lifecycle callback.
--  ``onClear`` - The ``onClear`` event occurs when the
-   ``EntityManager#clear()`` operation is invoked, after all references
-   to entities have been removed from the unit of work. This event is not
-   a lifecycle callback.
-
-
-.. warning::
-
-    Note that, when using ``Doctrine\ORM\AbstractQuery#toIterable()``, ``postLoad``
-    events will be executed immediately after objects are being hydrated, and therefore
-    associations are not guaranteed to be initialized. It is not safe to combine
-    usage of ``Doctrine\ORM\AbstractQuery#toIterable()`` and ``postLoad`` event
-    handlers.
-
-.. warning::
-
-    Note that the ``postRemove`` event or any events triggered after an entity removal
-    can receive an uninitializable proxy in case you have configured an entity to
-    cascade remove relations. In this case, you should load yourself the proxy in
-    the associated pre event.
-
-You can access the Event constants from the ``Events`` class in the
-ORM package.
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Events;
-    echo Events::preUpdate;
-
-These can be hooked into by two different types of event
-listeners:
-
--  Lifecycle Callbacks are methods on the entity classes that are
-   called when the event is triggered. They receive some kind
-   of ``EventArgs`` instance.
--  Lifecycle Event Listeners and Subscribers are classes with specific callback
-   methods that receives some kind of ``EventArgs`` instance.
-
-The ``EventArgs`` instance received by the listener gives access to the entity,
-``EntityManager`` instance and other relevant data.
-
-.. note::
-
-    All Lifecycle events that happen during the ``flush()`` of
-    an ``EntityManager`` have very specific constraints on the allowed
-    operations that can be executed. Please read the
-    :ref:`reference-events-implementing-listeners` section very carefully
-    to understand which operations are allowed in which lifecycle event.
-
-
-Lifecycle Callbacks
--------------------
-
-Lifecycle Callbacks are defined on an entity class. They allow you to
-trigger callbacks whenever an instance of that entity class experiences
-a relevant lifecycle event. More than one callback can be defined for each
-lifecycle event. Lifecycle Callbacks are best used for simple operations
-specific to a particular entity class's lifecycle.
-
-
-.. note::
-
-    Note that Licecycle Callbacks are not supported for Embeddables.
-
-.. code-block:: php
-
-    <?php
-
-    /** @Entity @HasLifecycleCallbacks */
-    class User
-    {
-        // ...
-
-        /**
-         * @Column(type="string", length=255)
-         */
-        public $value;
-
-        /** @Column(name="created_at", type="string", length=255) */
-        private $createdAt;
-
-        /** @PrePersist */
-        public function doStuffOnPrePersist()
-        {
-            $this->createdAt = date('Y-m-d H:i:s');
-        }
-
-        /** @PrePersist */
-        public function doOtherStuffOnPrePersist()
-        {
-            $this->value = 'changed from prePersist callback!';
-        }
-
-        /** @PostPersist */
-        public function doStuffOnPostPersist()
-        {
-            $this->value = 'changed from postPersist callback!';
-        }
-
-        /** @PostLoad */
-        public function doStuffOnPostLoad()
-        {
-            $this->value = 'changed from postLoad callback!';
-        }
-
-        /** @PreUpdate */
-        public function doStuffOnPreUpdate()
-        {
-            $this->value = 'changed from preUpdate callback!';
-        }
-    }
-
-Note that the methods set as lifecycle callbacks need to be public and,
-when using these annotations, you have to apply the
-``@HasLifecycleCallbacks`` marker annotation on the entity class.
-
-If you want to register lifecycle callbacks from YAML or XML you
-can do it with the following.
-
-.. code-block:: yaml
-
-    User:
-      type: entity
-      fields:
-    # ...
-        name:
-          type: string(50)
-      lifecycleCallbacks:
-        prePersist: [ doStuffOnPrePersist, doOtherStuffOnPrePersist ]
-        postPersist: [ doStuffOnPostPersist ]
-
-In YAML the ``key`` of the lifecycleCallbacks entry is the event that you
-are triggering on and the value is the method (or methods) to call. The allowed
-event types are the ones listed in the previous Lifecycle Events section.
-
-XML would look something like this:
-
-.. code-block:: xml
-
-    <?xml version="1.0" encoding="UTF-8"?>
-
-    <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
-          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-          xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
-                              https://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
-
-        <entity name="User">
-
-            <lifecycle-callbacks>
-                <lifecycle-callback type="prePersist" method="doStuffOnPrePersist"/>
-                <lifecycle-callback type="postPersist" method="doStuffOnPostPersist"/>
-            </lifecycle-callbacks>
-
-        </entity>
-
-    </doctrine-mapping>
-
-In XML the ``type`` of the lifecycle-callback entry is the event that you
-are triggering on and the ``method`` is the method to call. The allowed event
-types are the ones listed in the previous Lifecycle Events section.
-
-When using YAML or XML you need to remember to create public methods to match the
-callback names you defined. E.g. in these examples ``doStuffOnPrePersist()``,
-``doOtherStuffOnPrePersist()`` and ``doStuffOnPostPersist()`` methods need to be
-defined on your ``User`` model.
-
-.. code-block:: php
-
-    <?php
-    // ...
-
-    class User
-    {
-        // ...
-
-        public function doStuffOnPrePersist()
-        {
-            // ...
-        }
-
-        public function doOtherStuffOnPrePersist()
-        {
-            // ...
-        }
-
-        public function doStuffOnPostPersist()
-        {
-            // ...
-        }
-    }
-
-
-Lifecycle Callbacks Event Argument
------------------------------------
-
-The triggered event is also given to the lifecycle-callback.
-
-With the additional argument you have access to the
-``EntityManager`` and ``UnitOfWork`` APIs inside these callback methods.
-
-.. code-block:: php
-
-    <?php
-    // ...
-
-    class User
-    {
-        public function preUpdate(PreUpdateEventArgs $event)
-        {
-            if ($event->hasChangedField('username')) {
-                // Do something when the username is changed.
-            }
-        }
-    }
-
-Listening and subscribing to Lifecycle Events
----------------------------------------------
-
-Lifecycle event listeners are much more powerful than the simple
-lifecycle callbacks that are defined on the entity classes. They
-sit at a level above the entities and allow you to implement re-usable
-behaviors across different entity classes.
-
-Note that they require much more detailed knowledge about the inner
-workings of the ``EntityManager`` and ``UnitOfWork`` classes. Please
-read the :ref:`reference-events-implementing-listeners` section
-carefully if you are trying to write your own listener.
-
-For event subscribers, there are no surprises. They declare the
-lifecycle events in their ``getSubscribedEvents`` method and provide
-public methods that expect the relevant arguments.
-
-A lifecycle event listener looks like the following:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Persistence\Event\LifecycleEventArgs;
-
-    class MyEventListener
-    {
-        public function preUpdate(LifecycleEventArgs $args)
-        {
-            $entity = $args->getObject();
-            $entityManager = $args->getObjectManager();
-
-            // perhaps you only want to act on some "Product" entity
-            if ($entity instanceof Product) {
-                // do something with the Product
-            }
-        }
-    }
-
-A lifecycle event subscriber may look like this:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Events;
-    use Doctrine\EventSubscriber;
-    use Doctrine\Persistence\Event\LifecycleEventArgs;
-
-    class MyEventSubscriber implements EventSubscriber
-    {
-        public function getSubscribedEvents()
-        {
-            return array(
-                Events::postUpdate,
-            );
-        }
-
-        public function postUpdate(LifecycleEventArgs $args)
-        {
-            $entity = $args->getObject();
-            $entityManager = $args->getObjectManager();
-
-            // perhaps you only want to act on some "Product" entity
-            if ($entity instanceof Product) {
-                // do something with the Product
-            }
-        }
-
-.. note::
-
-    Lifecycle events are triggered for all entities. It is the responsibility
-    of the listeners and subscribers to check if the entity is of a type
-    it wants to handle.
-
-To register an event listener or subscriber, you have to hook it into the
-EventManager that is passed to the EntityManager factory:
-
-.. code-block:: php
-
-    <?php
-    $eventManager = new EventManager();
-    $eventManager->addEventListener(array(Events::preUpdate), new MyEventListener());
-    $eventManager->addEventSubscriber(new MyEventSubscriber());
-
-    $entityManager = EntityManager::create($dbOpts, $config, $eventManager);
-
-You can also retrieve the event manager instance after the
-EntityManager was created:
-
-.. code-block:: php
-
-    <?php
-    $entityManager->getEventManager()->addEventListener(array(Events::preUpdate), new MyEventListener());
-    $entityManager->getEventManager()->addEventSubscriber(new MyEventSubscriber());
-
-.. _reference-events-implementing-listeners:
-
-Implementing Event Listeners
-----------------------------
-
-This section explains what is and what is not allowed during
-specific lifecycle events of the ``UnitOfWork`` class. Although you get
-passed the ``EntityManager`` instance in all of these events, you have
-to follow these restrictions very carefully since operations in the
-wrong event may produce lots of different errors, such as inconsistent
-data and lost updates/persists/removes.
-
-For the described events that are also lifecycle callback events
-the restrictions apply as well, with the additional restriction
-that (prior to version 2.4) you do not have access to the
-``EntityManager`` or ``UnitOfWork`` APIs inside these events.
-
-prePersist
-~~~~~~~~~~
-
-There are two ways for the ``prePersist`` event to be triggered.
-One is obviously when you call ``EntityManager#persist()``. The
-event is also called for all cascaded associations.
-
-There is another way for ``prePersist`` to be called, inside the
-``flush()`` method when changes to associations are computed and
-this association is marked as cascade persist. Any new entity found
-during this operation is also persisted and ``prePersist`` called
-on it. This is called "persistence by reachability".
-
-In both cases you get passed a ``LifecycleEventArgs`` instance
-which has access to the entity and the entity manager.
-
-The following restrictions apply to ``prePersist``:
-
-
--  If you are using a PrePersist Identity Generator such as
-   sequences the ID value will *NOT* be available within any
-   PrePersist events.
--  Doctrine will not recognize changes made to relations in a prePersist
-   event. This includes modifications to
-   collections such as additions, removals or replacement.
-
-preRemove
-~~~~~~~~~
-
-The ``preRemove`` event is called on every entity when its passed
-to the ``EntityManager#remove()`` method. It is cascaded for all
-associations that are marked as cascade delete.
-
-There are no restrictions to what methods can be called inside the
-``preRemove`` event, except when the remove method itself was
-called during a flush operation.
-
-preFlush
-~~~~~~~~
-
-``preFlush`` is called at ``EntityManager#flush()`` before
-anything else. ``EntityManager#flush()`` should not be called inside
-its listeners, since `preFlush` event is dispatched in it, which would
-result in infinite loop.
-
-.. code-block:: php
-
-    <?php
-
-    use Doctrine\ORM\Event\PreFlushEventArgs;
-
-    class PreFlushExampleListener
-    {
-        public function preFlush(PreFlushEventArgs $args)
-        {
-            // ...
-        }
-    }
-
-onFlush
-~~~~~~~
-
-OnFlush is a very powerful event. It is called inside
-``EntityManager#flush()`` after the changes to all the managed
-entities and their associations have been computed. This means, the
-``onFlush`` event has access to the sets of:
-
-
--  Entities scheduled for insert
--  Entities scheduled for update
--  Entities scheduled for removal
--  Collections scheduled for update
--  Collections scheduled for removal
-
-To make use of the ``onFlush`` event you have to be familiar with the
-internal ``UnitOfWork`` API, which grants you access to the previously
-mentioned sets. See this example:
-
-.. code-block:: php
-
-    <?php
-    class FlushExampleListener
-    {
-        public function onFlush(OnFlushEventArgs $eventArgs)
-        {
-            $em = $eventArgs->getEntityManager();
-            $uow = $em->getUnitOfWork();
-
-            foreach ($uow->getScheduledEntityInsertions() as $entity) {
-
-            }
-
-            foreach ($uow->getScheduledEntityUpdates() as $entity) {
-
-            }
-
-            foreach ($uow->getScheduledEntityDeletions() as $entity) {
-
-            }
-
-            foreach ($uow->getScheduledCollectionDeletions() as $col) {
-
-            }
-
-            foreach ($uow->getScheduledCollectionUpdates() as $col) {
-
-            }
-        }
-    }
-
-The following restrictions apply to the onFlush event:
-
-
--  If you create and persist a new entity in ``onFlush``, then
-   calling ``EntityManager#persist()`` is not enough.
-   You have to execute an additional call to
-   ``$unitOfWork->computeChangeSet($classMetadata, $entity)``.
--  Changing primitive fields or associations requires you to
-   explicitly trigger a re-computation of the changeset of the
-   affected entity. This can be done by calling
-   ``$unitOfWork->recomputeSingleEntityChangeSet($classMetadata, $entity)``.
-
-postFlush
-~~~~~~~~~
-
-``postFlush`` is called at the end of ``EntityManager#flush()``.
-``EntityManager#flush()`` can **NOT** be called safely inside its listeners.
-
-.. code-block:: php
-
-    <?php
-
-    use Doctrine\ORM\Event\PostFlushEventArgs;
-
-    class PostFlushExampleListener
-    {
-        public function postFlush(PostFlushEventArgs $args)
-        {
-            // ...
-        }
-    }
-
-preUpdate
-~~~~~~~~~
-
-PreUpdate is the most restrictive to use event, since it is called
-right before an update statement is called for an entity inside the
-``EntityManager#flush()`` method. Note that this event is not
-triggered when the computed changeset is empty.
-
-Changes to associations of the updated entity are never allowed in
-this event, since Doctrine cannot guarantee to correctly handle
-referential integrity at this point of the flush operation. This
-event has a powerful feature however, it is executed with a
-``PreUpdateEventArgs`` instance, which contains a reference to the
-computed change-set of this entity.
-
-This means you have access to all the fields that have changed for
-this entity with their old and new value. The following methods are
-available on the ``PreUpdateEventArgs``:
-
-
--  ``getEntity()`` to get access to the actual entity.
--  ``getEntityChangeSet()`` to get a copy of the changeset array.
-   Changes to this returned array do not affect updating.
--  ``hasChangedField($fieldName)`` to check if the given field name
-   of the current entity changed.
--  ``getOldValue($fieldName)`` and ``getNewValue($fieldName)`` to
-   access the values of a field.
--  ``setNewValue($fieldName, $value)`` to change the value of a
-   field to be updated.
-
-A simple example for this event looks like:
-
-.. code-block:: php
-
-    <?php
-    class NeverAliceOnlyBobListener
-    {
-        public function preUpdate(PreUpdateEventArgs $eventArgs)
-        {
-            if ($eventArgs->getEntity() instanceof User) {
-                if ($eventArgs->hasChangedField('name') && $eventArgs->getNewValue('name') == 'Alice') {
-                    $eventArgs->setNewValue('name', 'Bob');
-                }
-            }
-        }
-    }
-
-You could also use this listener to implement validation of all the
-fields that have changed. This is more efficient than using a
-lifecycle callback when there are expensive validations to call:
-
-.. code-block:: php
-
-    <?php
-    class ValidCreditCardListener
-    {
-        public function preUpdate(PreUpdateEventArgs $eventArgs)
-        {
-            if ($eventArgs->getEntity() instanceof Account) {
-                if ($eventArgs->hasChangedField('creditCard')) {
-                    $this->validateCreditCard($eventArgs->getNewValue('creditCard'));
-                }
-            }
-        }
-
-        private function validateCreditCard($no)
-        {
-            // throw an exception to interrupt flush event. Transaction will be rolled back.
-        }
-    }
-
-Restrictions for this event:
-
-
--  Changes to associations of the passed entities are not
-   recognized by the flush operation anymore.
--  Changes to fields of the passed entities are not recognized by
-   the flush operation anymore, use the computed change-set passed to
-   the event to modify primitive field values, e.g. use
-   ``$eventArgs->setNewValue($field, $value);`` as in the Alice to Bob example above.
--  Any calls to ``EntityManager#persist()`` or
-   ``EntityManager#remove()``, even in combination with the ``UnitOfWork``
-   API are strongly discouraged and don't work as expected outside the
-   flush operation.
-
-postUpdate, postRemove, postPersist
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The three post events are called inside ``EntityManager#flush()``.
-Changes in here are not relevant to the persistence in the
-database, but you can use these events to alter non-persistable items,
-like non-mapped fields, logging or even associated classes that are
-not directly mapped by Doctrine.
-
-postLoad
-~~~~~~~~
-
-This event is called after an entity is constructed by the
-EntityManager.
-
-Entity listeners
-----------------
-
-An entity listener is a lifecycle listener class used for an entity.
-
-- The entity listener's mapping may be applied to an entity class or mapped superclass.
-- An entity listener is defined by mapping the entity class with the corresponding mapping.

-
-Entity listeners class
-~~~~~~~~~~~~~~~~~~~~~~
-
-An ``Entity Listener`` could be any class, by default it should be a class with a no-arg constructor.
-
-- Different from :ref:`reference-events-implementing-listeners` an ``Entity Listener`` is invoked just to the specified entity
-- An entity listener method receives two arguments, the entity instance and the lifecycle event.
-- The callback method can be defined by naming convention or specifying a method mapping.
-- When a listener mapping is not given the parser will use the naming convention to look for a matching method,
-  e.g. it will look for a public ``preUpdate()`` method if you are listening to the ``preUpdate`` event.
-- When a listener mapping is given the parser will not look for any methods using the naming convention.
-
-.. code-block:: php
-
-    <?php
-    class UserListener
-    {
-        public function preUpdate(User $user, PreUpdateEventArgs $event)
-        {
-            // Do something on pre update.
-        }
-    }
-
-To define a specific event listener method (one that does not follow the naming convention)
-you need to map the listener method using the event type mapping:
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        class UserListener
-        {
-            /** @PrePersist */
-            public function prePersistHandler(User $user, LifecycleEventArgs $event) { // ... }
-
-            /** @PostPersist */
-            public function postPersistHandler(User $user, LifecycleEventArgs $event) { // ... }
-
-            /** @PreUpdate */
-            public function preUpdateHandler(User $user, PreUpdateEventArgs $event) { // ... }
-
-            /** @PostUpdate */
-            public function postUpdateHandler(User $user, LifecycleEventArgs $event) { // ... }
-
-            /** @PostRemove */
-            public function postRemoveHandler(User $user, LifecycleEventArgs $event) { // ... }
-

-

-            public function preFlushHandler(User $user, PreFlushEventArgs $event) { // ... }
-
-            /** @PostLoad */
-            public function postLoadHandler(User $user, LifecycleEventArgs $event) { // ... }

-
-              postPersist: [postPersistHandler]

-          # ....
-
-.. note::
-
-    The order of execution of multiple methods for the same event (e.g. multiple @PrePersist) is not guaranteed.
-
-
-Entity listeners resolver
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-Doctrine invokes the listener resolver to get the listener instance.
-
-- A resolver allows you register a specific entity listener instance.
-- You can also implement your own resolver by extending ``Doctrine\ORM\Mapping\DefaultEntityListenerResolver`` or implementing ``Doctrine\ORM\Mapping\EntityListenerResolver``
-
-Specifying an entity listener instance :
-
-.. code-block:: php
-
-    <?php
-    // User.php
-
-    /** @Entity @EntityListeners({"UserListener"}) */
-    class User
-    {
-        // ....
-    }
-
-    // UserListener.php
-    class UserListener
-    {
-        public function __construct(MyService $service)
-        {
-            $this->service = $service;
-        }
-
-        public function preUpdate(User $user, PreUpdateEventArgs $event)
-        {
-            $this->service->doSomething($user);
-        }
-    }
-
-    // register a entity listener.
-    $listener = $container->get('user_listener');
-    $em->getConfiguration()->getEntityListenerResolver()->register($listener);
-
-Implementing your own resolver :
-
-.. code-block:: php
-
-    <?php
-    class MyEntityListenerResolver extends \Doctrine\ORM\Mapping\DefaultEntityListenerResolver
-    {
-        public function __construct($container)
-        {
-            $this->container = $container;
-        }
-
-        public function resolve($className)
-        {
-            // resolve the service id by the given class name;
-            $id = 'user_listener';
-
-            return $this->container->get($id);
-        }
-    }
-
-    // Configure the listener resolver only before instantiating the EntityManager
-    $configurations->setEntityListenerResolver(new MyEntityListenerResolver);
-    EntityManager::create(.., $configurations, ..);
-
-Load ClassMetadata Event
-------------------------
-
-When the mapping information for an entity is read, it is populated
-in to a ``ClassMetadataInfo`` instance. You can hook in to this
-process and manipulate the instance.
-
-.. code-block:: php
-
-    <?php
-    $test = new TestEvent();
-    $metadataFactory = $em->getMetadataFactory();
-    $evm = $em->getEventManager();
-    $evm->addEventListener(Events::loadClassMetadata, $test);
-
-    class TestEvent
-    {
-        public function loadClassMetadata(\Doctrine\ORM\Event\LoadClassMetadataEventArgs $eventArgs)
-        {
-            $classMetadata = $eventArgs->getClassMetadata();
-            $fieldMapping = array(
-                'fieldName' => 'about',
-                'type' => 'string',
-                'length' => 255
-            );
-            $classMetadata->mapField($fieldMapping);
-        }
-    }

-Frequently Asked Questions
-==========================
-
-.. note::
-
-    This FAQ is a work in progress. We will add lots of questions and not answer them right away just to remember
-    what is often asked. If you stumble across an unanswered question please write a mail to the mailing-list or
-    join the #doctrine channel on Freenode IRC.
-
-Database Schema
----------------
-
-How do I set the charset and collation for MySQL tables?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can't set these values inside the annotations, yml or xml mapping files. To make a database
-work with the default charset and collation you should configure MySQL to use it as default charset,
-or create the database with charset and collation details. This way they get inherited to all newly
-created database tables and columns.
-
-Entity Classes
---------------
-
-How can I add default values to a column?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Doctrine does not support to set the default values in columns through the "DEFAULT" keyword in SQL.
-This is not necessary however, you can just use your class properties as default values. These are then used
-upon insert:
-
-.. code-block:: php
-
-    class User
-    {
-        const STATUS_DISABLED = 0;
-        const STATUS_ENABLED = 1;
-
-        private $algorithm = "sha1";
-        private $status = self:STATUS_DISABLED;
-    }
-
-.
-
-Mapping
--------
-
-Why do I get exceptions about unique constraint failures during ``$em->flush()``?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Doctrine does not check if you are re-adding entities with a primary key that already exists
-or adding entities to a collection twice. You have to check for both conditions yourself
-in the code before calling ``$em->flush()`` if you know that unique constraint failures
-can occur.
-
-In `Symfony2 <http://www.symfony.com>`_ for example there is a Unique Entity Validator
-to achieve this task.
-
-For collections you can check with ``$collection->contains($entity)`` if an entity is already
-part of this collection. For a FETCH=LAZY collection this will initialize the collection,
-however for FETCH=EXTRA_LAZY this method will use SQL to determine if this entity is already
-part of the collection.
-
-Associations
-------------
-
-What is wrong when I get an InvalidArgumentException "A new entity was found through the relationship.."?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This exception is thrown during ``EntityManager#flush()`` when there exists an object in the identity map
-that contains a reference to an object that Doctrine does not know about. Say for example you grab
-a "User"-entity from the database with a specific id and set a completely new object into one of the associations
-of the User object. If you then call ``EntityManager#flush()`` without letting Doctrine know about
-this new object using ``EntityManager#persist($newObject)`` you will see this exception.
-
-You can solve this exception by:
-
-* Calling ``EntityManager#persist($newObject)`` on the new object
-* Using cascade=persist on the association that contains the new object
-
-How can I filter an association?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You should use DQL queries to query for the filtered set of entities.
-
-I call clear() on a One-To-Many collection but the entities are not deleted
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This is an expected behavior that has to do with the inverse/owning side handling of Doctrine.
-By definition a One-To-Many association is on the inverse side, that means changes to it
-will not be recognized by Doctrine.
-
-If you want to perform the equivalent of the clear operation you have to iterate the
-collection and set the owning side many-to-one reference to NULL as well to detach all entities
-from the collection. This will trigger the appropriate UPDATE statements on the database.
-
-How can I add columns to a many-to-many table?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The many-to-many association is only supporting foreign keys in the table definition
-To work with many-to-many tables containing extra columns you have to use the
-foreign keys as primary keys feature of Doctrine ORM.
-
-See :doc:`the tutorial on composite primary keys for more information<../tutorials/composite-primary-keys>`.
-
-
-How can i paginate fetch-joined collections?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If you are issuing a DQL statement that fetches a collection as well you cannot easily iterate
-over this collection using a LIMIT statement (or vendor equivalent).
-
-Doctrine does not offer a solution for this out of the box but there are several extensions
-that do:
-
-* `DoctrineExtensions <http://github.com/beberlei/DoctrineExtensions>`_
-* `Pagerfanta <http://github.com/whiteoctober/pagerfanta>`_
-
-Why does pagination not work correctly with fetch joins?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Pagination in Doctrine uses a LIMIT clause (or vendor equivalent) to restrict the results.
-However when fetch-joining this is not returning the correct number of results since joining
-with a one-to-many or many-to-many association multiplies the number of rows by the number
-of associated entities.
-
-See the previous question for a solution to this task.
-
-Inheritance
------------
-
-Can I use Inheritance with Doctrine ORM?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Yes, you can use Single- or Joined-Table Inheritance in ORM.
-
-See the documentation chapter on :doc:`inheritance mapping <inheritance-mapping>` for
-the details.
-
-Why does Doctrine not create proxy objects for my inheritance hierarchy?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If you set a many-to-one or one-to-one association target-entity to any parent class of
-an inheritance hierarchy Doctrine does not know what PHP class the foreign is actually of.
-To find this out it has to execute a SQL query to look this information up in the database.
-
-EntityGenerator
----------------
-
-Why does the EntityGenerator not do X?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The EntityGenerator is not a full fledged code-generator that solves all tasks. Code-Generation
-is not a first-class priority in Doctrine 2 anymore (compared to Doctrine 1). The EntityGenerator
-is supposed to kick-start you, but not towards 100%.
-
-Why does the EntityGenerator not generate inheritance correctly?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Just from the details of the discriminator map the EntityGenerator cannot guess the inheritance hierarchy.
-This is why the generation of inherited entities does not fully work. You have to adjust some additional
-code to get this one working correctly.
-
-Performance
------------
-
-Why is an extra SQL query executed every time I fetch an entity with a one-to-one relation?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If Doctrine detects that you are fetching an inverse side one-to-one association
-it has to execute an additional query to load this object, because it cannot know
-if there is no such object (setting null) or if it should set a proxy and which id this proxy has.
-
-To solve this problem currently a query has to be executed to find out this information.
-
-Doctrine Query Language
------------------------
-
-What is DQL?
-~~~~~~~~~~~~
-
-DQL stands for Doctrine Query Language, a query language that very much looks like SQL
-but has some important benefits when using Doctrine:
-
--  It uses class names and fields instead of tables and columns, separating concerns between backend and your object model.
--  It utilizes the metadata defined to offer a range of shortcuts when writing. For example you do not have to specify the ON clause of joins, since Doctrine already knows about them.
--  It adds some functionality that is related to object management and transforms them into SQL.
-
-It also has some drawbacks of course:
-
--  The syntax is slightly different to SQL so you have to learn and remember the differences.
--  To be vendor independent it can only implement a subset of all the existing SQL dialects. Vendor specific functionality and optimizations cannot be used through DQL unless implemented by you explicitly.
--  For some DQL constructs subselects are used which are known to be slow in MySQL.
-
-Can I sort by a function (for example ORDER BY RAND()) in DQL?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-No, it is not supported to sort by function in DQL. If you need this functionality you should either
-use a native-query or come up with another solution. As a side note: Sorting with ORDER BY RAND() is painfully slow
-starting with 1000 rows.
-
-Is it better to write DQL or to generate it with the query builder?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The purpose of the ``QueryBuilder`` is to generate DQL dynamically,
-which is useful when you have optional filters, conditional joins, etc.
-
-But the ``QueryBuilder`` is not an alternative to DQL, it actually generates DQL
-queries at runtime, which are then interpreted by Doctrine. This means that
-using the ``QueryBuilder`` to build and run a query is actually always slower
-than only running the corresponding DQL query.
-
-So if you only need to generate a query and bind parameters to it,
-you should use plain DQL, as this is a simpler and much more readable solution.
-You should only use the ``QueryBuilder`` when you can't achieve what you want to do with a DQL query.
-
-A Query fails, how can I debug it?
-----------------------------------
-
-First, if you are using the QueryBuilder you can use
-``$queryBuilder->getDQL()`` to get the DQL string of this query. The
-corresponding SQL you can get from the Query instance by calling
-``$query->getSQL()``.
-
-.. code-block:: php
-
-    <?php
-    $dql = "SELECT u FROM User u";
-    $query = $entityManager->createQuery($dql);
-    var_dump($query->getSQL());
-
-    $qb = $entityManager->createQueryBuilder();
-    $qb->select('u')->from('User', 'u');
-    var_dump($qb->getDQL());

-Filters
-=======
-
-Doctrine ORM features a filter system that allows the developer to add SQL to
-the conditional clauses of queries, regardless the place where the SQL is
-generated (e.g. from a DQL query, or by loading associated entities).
-
-The filter functionality works on SQL level. Whether a SQL query is generated
-in a Persister, during lazy loading, in extra lazy collections or from DQL.
-Each time the system iterates over all the enabled filters, adding a new SQL
-part as a filter returns.
-
-By adding SQL to the conditional clauses of queries, the filter system filters
-out rows belonging to the entities at the level of the SQL result set. This
-means that the filtered entities are never hydrated (which can be expensive).
-
-
-Example filter class
---------------------
-Throughout this document the example ``MyLocaleFilter`` class will be used to
-illustrate how the filter feature works. A filter class must extend the base
-``Doctrine\ORM\Query\Filter\SQLFilter`` class and implement the ``addFilterConstraint``
-method. The method receives the ``ClassMetadata`` of the filtered entity and the
-table alias of the SQL table of the entity.
-
-.. note::
-
-    In the case of joined or single table inheritance, you always get passed the ClassMetadata of the
-    inheritance root. This is necessary to avoid edge cases that would break the SQL when applying the filters.
-
-Parameters for the query should be set on the filter object by
-``SQLFilter#setParameter()``. Only parameters set via this function can be used
-in filters.  The ``SQLFilter#getParameter()`` function takes care of the
-proper quoting of parameters.
-
-.. code-block:: php
-
-    <?php
-    namespace Example;
-    use Doctrine\ORM\Mapping\ClassMetadata,
-        Doctrine\ORM\Query\Filter\SQLFilter;
-
-    class MyLocaleFilter extends SQLFilter
-    {
-        public function addFilterConstraint(ClassMetadata $targetEntity, $targetTableAlias)
-        {
-            // Check if the entity implements the LocalAware interface
-            if (!$targetEntity->reflClass->implementsInterface('LocaleAware')) {
-                return "";
-            }
-
-            return $targetTableAlias.'.locale = ' . $this->getParameter('locale'); // getParameter applies quoting automatically
-        }
-    }
-
-
-Configuration
--------------
-Filter classes are added to the configuration as following:
-
-.. code-block:: php
-
-    <?php
-    $config->addFilter("locale", "\Doctrine\Tests\ORM\Functional\MyLocaleFilter");
-
-
-The ``Configuration#addFilter()`` method takes a name for the filter and the name of the
-class responsible for the actual filtering.
-
-
-Disabling/Enabling Filters and Setting Parameters
----------------------------------------------------
-Filters can be disabled and enabled via the ``FilterCollection`` which is
-stored in the ``EntityManager``. The ``FilterCollection#enable($name)`` method
-will retrieve the filter object. You can set the filter parameters on that
-object.
-
-.. code-block:: php
-
-    <?php
-    $filter = $em->getFilters()->enable("locale");
-    $filter->setParameter('locale', 'en');
-
-    // Disable it
-    $filter = $em->getFilters()->disable("locale");
-
-.. warning::
-    Disabling and enabling filters has no effect on managed entities. If you
-    want to refresh or reload an object after having modified a filter or the
-    FilterCollection, then you should clear the EntityManager and re-fetch your
-    entities, having the new rules for filtering applied.

-Improving Performance
-=====================
-
-Bytecode Cache
---------------
-
-It is highly recommended to make use of a bytecode cache like OPcache.
-A bytecode cache removes the need for parsing PHP code on every
-request and can greatly improve performance.
-
-    "If you care about performance and don't use a bytecode
-    cache then you don't really care about performance. Please get one
-    and start using it."
-    
-    *Stas Malyshev, Core Contributor to PHP and Zend Employee*
-
-
-Metadata and Query caches
--------------------------
-
-As already mentioned earlier in the chapter about configuring
-Doctrine, it is strongly discouraged to use Doctrine without a
-Metadata and Query cache.
-
-Operating Doctrine without these caches means
-Doctrine will need to load your mapping information on every single
-request and has to parse each DQL query on every single request.
-This is a waste of resources.
-
-The preferred cache driver for metadata and query caches is ``PhpFileCache``. 
-This driver serializes cache items and writes them to a file. 
-This allows for opcode caching to be used and provides high performance in most scenarios.
-
-See :ref:`integrating-with-the-orm`
-
-Alternative Query Result Formats
---------------------------------
-
-Make effective use of the available alternative query result
-formats like nested array graphs or pure scalar results, especially
-in scenarios where data is loaded for read-only purposes.
-
-Read-Only Entities
-------------------
-
-You can mark entities as read only (See metadata mapping
-references for details). This means that the entity marked as read only is never considered
-for updates, which means when you call flush on the EntityManager these entities are skipped
-even if properties changed. Read-Only allows to persist new entities of a kind and remove existing
-ones, they are just not considered for updates.
-
-See :ref:`annref_entity`
-
-Extra-Lazy Collections
-----------------------
-
-If entities hold references to large collections you will get performance and memory problems initializing them.
-To solve this issue you can use the EXTRA_LAZY fetch-mode feature for collections. See the :doc:`tutorial <../tutorials/extra-lazy-associations>`
-for more information on how this fetch mode works.
-
-Temporarily change fetch mode in DQL
-------------------------------------
-
-See :ref:`dql-temporarily-change-fetch-mode`

-also positively affect the performance of Doctrine.

-Inheritance Mapping
-===================
-
-Mapped Superclasses
--------------------
-
-A mapped superclass is an abstract or concrete class that provides
-persistent entity state and mapping information for its subclasses,
-but which is not itself an entity. Typically, the purpose of such a
-mapped superclass is to define state and mapping information that
-is common to multiple entity classes.
-
-Mapped superclasses, just as regular, non-mapped classes, can
-appear in the middle of an otherwise mapped inheritance hierarchy
-(through Single Table Inheritance or Class Table Inheritance).
-
-.. note::
-
-    A mapped superclass cannot be an entity, it is not query-able and
-    persistent relationships defined by a mapped superclass must be
-    unidirectional (with an owning side only). This means that One-To-Many
-    associations are not possible on a mapped superclass at all.
-    Furthermore Many-To-Many associations are only possible if the
-    mapped superclass is only used in exactly one entity at the moment.
-    For further support of inheritance, the single or
-    joined table inheritance features have to be used.
-
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    /** @MappedSuperclass */
-    class MappedSuperclassBase
-    {
-        /** @Column(type="integer") */
-        protected $mapped1;
-        /** @Column(type="string") */
-        protected $mapped2;
-        /**
-         * @OneToOne(targetEntity="MappedSuperclassRelated1")
-         * @JoinColumn(name="related1_id", referencedColumnName="id")
-         */
-        protected $mappedRelated1;
-    
-        // ... more fields and methods
-    }
-    
-    /** @Entity */
-    class EntitySubClass extends MappedSuperclassBase
-    {
-        /** @Id @Column(type="integer") */
-        private $id;
-        /** @Column(type="string") */
-        private $name;
-    
-        // ... more fields and methods
-    }
-
-The DDL for the corresponding database schema would look something
-like this (this is for SQLite):
-
-.. code-block:: sql
-
-    CREATE TABLE EntitySubClass (mapped1 INTEGER NOT NULL, mapped2 TEXT NOT NULL, id INTEGER NOT NULL, name TEXT NOT NULL, related1_id INTEGER DEFAULT NULL, PRIMARY KEY(id))
-
-As you can see from this DDL snippet, there is only a single table
-for the entity subclass. All the mappings from the mapped
-superclass were inherited to the subclass as if they had been
-defined on that class directly.
-
-Single Table Inheritance
-------------------------
-
-`Single Table Inheritance <http://martinfowler.com/eaaCatalog/singleTableInheritance.html>`_
-is an inheritance mapping strategy where all classes of a hierarchy
-are mapped to a single database table. In order to distinguish
-which row represents which type in the hierarchy a so-called
-discriminator column is used.
-
-Example:
-
-.. configuration-block::
-
-    .. code-block:: php
-    
-        <?php
-        namespace MyProject\Model;
-        
-        /**
-         * @Entity
-         * @InheritanceType("SINGLE_TABLE")
-         * @DiscriminatorColumn(name="discr", type="string")
-         * @DiscriminatorMap({"person" = "Person", "employee" = "Employee"})
-         */
-        class Person
-        {
-            // ...
-        }
-        
-        /**
-         * @Entity
-         */
-        class Employee extends Person
-        {
-            // ...
-        }
-
-    .. code-block:: yaml
-    
-        MyProject\Model\Person:
-          type: entity
-          inheritanceType: SINGLE_TABLE
-          discriminatorColumn:
-            name: discr
-            type: string
-          discriminatorMap:
-            person: Person
-            employee: Employee
-                
-        MyProject\Model\Employee:
-          type: entity
-            
-Things to note:
-
-
--  The @InheritanceType and @DiscriminatorColumn must be specified 
-   on the topmost class that is part of the mapped entity hierarchy.
--  The @DiscriminatorMap specifies which values of the
-   discriminator column identify a row as being of a certain type. In
-   the case above a value of "person" identifies a row as being of
-   type ``Person`` and "employee" identifies a row as being of type
-   ``Employee``.
--  All entity classes that is part of the mapped entity hierarchy
-   (including the topmost class) should be specified in the
-   @DiscriminatorMap. In the case above Person class included.
--  The names of the classes in the discriminator map do not need to
-   be fully qualified if the classes are contained in the same
-   namespace as the entity class on which the discriminator map is
-   applied.
--  If no discriminator map is provided, then the map is generated
-   automatically. The automatically generated discriminator map 
-   contains the lowercase short name of each class as key.
-
-Design-time considerations
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This mapping approach works well when the type hierarchy is fairly
-simple and stable. Adding a new type to the hierarchy and adding
-fields to existing supertypes simply involves adding new columns to
-the table, though in large deployments this may have an adverse
-impact on the index and column layout inside the database.
-
-Performance impact
-~~~~~~~~~~~~~~~~~~
-
-This strategy is very efficient for querying across all types in
-the hierarchy or for specific types. No table joins are required,
-only a WHERE clause listing the type identifiers. In particular,
-relationships involving types that employ this mapping strategy are
-very performing.
-
-There is a general performance consideration with Single Table
-Inheritance: If the target-entity of a many-to-one or one-to-one 
-association is an STI entity, it is preferable for performance reasons that it 
-be a leaf entity in the inheritance hierarchy, (ie. have no subclasses). 
-Otherwise Doctrine *CANNOT* create proxy instances
-of this entity and will *ALWAYS* load the entity eagerly.
-
-SQL Schema considerations
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-For Single-Table-Inheritance to work in scenarios where you are
-using either a legacy database schema or a self-written database
-schema you have to make sure that all columns that are not in the
-root entity but in any of the different sub-entities has to allow
-null values. Columns that have NOT NULL constraints have to be on
-the root entity of the single-table inheritance hierarchy.
-
-Class Table Inheritance
------------------------
-
-`Class Table Inheritance <http://martinfowler.com/eaaCatalog/classTableInheritance.html>`_
-is an inheritance mapping strategy where each class in a hierarchy
-is mapped to several tables: its own table and the tables of all
-parent classes. The table of a child class is linked to the table
-of a parent class through a foreign key constraint. Doctrine ORM
-implements this strategy through the use of a discriminator column
-in the topmost table of the hierarchy because this is the easiest
-way to achieve polymorphic queries with Class Table Inheritance.
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    namespace MyProject\Model;
-    
-    /**
-     * @Entity
-     * @InheritanceType("JOINED")
-     * @DiscriminatorColumn(name="discr", type="string")
-     * @DiscriminatorMap({"person" = "Person", "employee" = "Employee"})
-     */
-    class Person
-    {
-        // ...
-    }
-    
-    /** @Entity */
-    class Employee extends Person
-    {
-        // ...
-    }
-
-Things to note:
-
-
--  The @InheritanceType, @DiscriminatorColumn and @DiscriminatorMap
-   must be specified on the topmost class that is part of the mapped
-   entity hierarchy.
--  The @DiscriminatorMap specifies which values of the
-   discriminator column identify a row as being of which type. In the
-   case above a value of "person" identifies a row as being of type
-   ``Person`` and "employee" identifies a row as being of type
-   ``Employee``.
--  The names of the classes in the discriminator map do not need to
-   be fully qualified if the classes are contained in the same
-   namespace as the entity class on which the discriminator map is
-   applied.
--  If no discriminator map is provided, then the map is generated
-   automatically. The automatically generated discriminator map 
-   contains the lowercase short name of each class as key.
-
-.. note::
-
-    When you do not use the SchemaTool to generate the
-    required SQL you should know that deleting a class table
-    inheritance makes use of the foreign key property
-    ``ON DELETE CASCADE`` in all database implementations. A failure to
-    implement this yourself will lead to dead rows in the database.
-
-
-Design-time considerations
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Introducing a new type to the hierarchy, at any level, simply
-involves interjecting a new table into the schema. Subtypes of that
-type will automatically join with that new type at runtime.
-Similarly, modifying any entity type in the hierarchy by adding,
-modifying or removing fields affects only the immediate table
-mapped to that type. This mapping strategy provides the greatest
-flexibility at design time, since changes to any type are always
-limited to that type's dedicated table.
-
-Performance impact
-~~~~~~~~~~~~~~~~~~
-
-This strategy inherently requires multiple JOIN operations to
-perform just about any query which can have a negative impact on
-performance, especially with large tables and/or large hierarchies.
-When partial objects are allowed, either globally or on the
-specific query, then querying for any type will not cause the
-tables of subtypes to be OUTER JOINed which can increase
-performance but the resulting partial objects will not fully load
-themselves on access of any subtype fields, so accessing fields of
-subtypes after such a query is not safe.
-
-There is a general performance consideration with Class Table
-Inheritance: If the target-entity of a many-to-one or one-to-one 
-association is a CTI entity, it is preferable for performance reasons that it 
-be a leaf entity in the inheritance hierarchy, (ie. have no subclasses). 
-Otherwise Doctrine *CANNOT* create proxy instances
-of this entity and will *ALWAYS* load the entity eagerly.
-
-SQL Schema considerations
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-For each entity in the Class-Table Inheritance hierarchy all the
-mapped fields have to be columns on the table of this entity.
-Additionally each child table has to have an id column that matches
-the id column definition on the root table (except for any sequence
-or auto-increment details). Furthermore each child table has to
-have a foreign key pointing from the id column to the root table id
-column and cascading on delete.

-Overrides
----------
-
-Used to override a mapping for an entity field or relationship.  Can only be
-applied to an entity that extends a mapped superclass or uses a trait to
-override a relationship or field mapping defined by the mapped superclass or
-trait.
-
-It is not possible to override attributes or associations in entity to entity
-inheritance scenarios, because this can cause unforseen edge case behavior and
-increases complexity in ORM internal classes.
-
-
-Association Override
-~~~~~~~~~~~~~~~~~~~~
-Override a mapping for an entity relationship.
-
-Could be used by an entity that extends a mapped superclass
-to override a relationship mapping defined by the mapped superclass.

-
-Things to note:
-
--  The "association override" specifies the overrides base on the property name.
--  This feature is available for all kind of associations. (OneToOne, OneToMany, ManyToOne, ManyToMany)
--  The association type *CANNOT* be changed.
--  The override could redefine the joinTables or joinColumns depending on the association type.
--  The override could redefine inversedBy to reference more than one extended entity.
--  The override could redefine fetch to modify the fetch strategy of the extended entity.
-
-Attribute Override
-~~~~~~~~~~~~~~~~~~~~
-Override the mapping of a field.
-
-Could be used by an entity that extends a mapped superclass to override a field mapping defined by the mapped superclass.

--  The column type *CANNOT* be changed. If the column type is not equal you get a ``MappingException``
--  The override can redefine all the attributes except the type.
-
-Query the Type
---------------
-
-It may happen that the entities of a special type should be queried. Because there
-is no direct access to the discriminator column, Doctrine provides the
-``INSTANCE OF`` construct.
-
-The following example shows how to use ``INSTANCE OF``. There is a three level hierarchy
-with a base entity ``NaturalPerson`` which is extended by ``Staff`` which in turn
-is extended by ``Technician``.
-
-Querying for the staffs without getting any technicians can be achieved by this DQL:
-
-.. code-block:: php
-
-    <?php
-    $query = $em->createQuery("SELECT staff FROM MyProject\Model\Staff staff WHERE staff NOT INSTANCE OF MyProject\Model\Technician");
-    $staffs = $query->getResult();

-Limitations and Known Issues
-============================
-
-We try to make using Doctrine2 a very pleasant experience.
-Therefore we think it is very important to be honest about the
-current limitations to our users. Much like every other piece of
-software Doctrine2 is not perfect and far from feature complete.
-This section should give you an overview of current limitations of
-Doctrine ORM as well as critical known issues that you should know
-about.
-
-Current Limitations
--------------------
-
-There is a set of limitations that exist currently which might be
-solved in the future. Any of this limitations now stated has at
-least one ticket in the Tracker and is discussed for future
-releases.
-
-Join-Columns with non-primary keys
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-It is not possible to use join columns pointing to non-primary keys. Doctrine will think these are the primary
-keys and create lazy-loading proxies with the data, which can lead to unexpected results. Doctrine can for performance
-reasons not validate the correctness of this settings at runtime but only through the Validate Schema command.
-
-Mapping Arrays to a Join Table
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Related to the previous limitation with "Foreign Keys as
-Identifier" you might be interested in mapping the same table
-structure as given above to an array. However this is not yet
-possible either. See the following example:
-
-.. code-block:: sql
-
-    CREATE TABLE product (
-        id INTEGER,
-        name VARCHAR,
-        PRIMARY KEY(id)
-    );
-    
-    CREATE TABLE product_attributes (
-        product_id INTEGER,
-        attribute_name VARCHAR,
-        attribute_value VARCHAR,
-        PRIMARY KEY (product_id, attribute_name)
-    );
-
-This schema should be mapped to a Product Entity as follows:
-
-.. code-block:: php
-
-    class Product
-    {
-        private $id;
-        private $name;
-        private $attributes = array();
-    }
-
-Where the ``attribute_name`` column contains the key and
-``attribute_value`` contains the value of each array element in
-``$attributes``.
-
-The feature request for persistence of primitive value arrays
-`is described in the DDC-298 ticket <https://github.com/doctrine/orm/issues/3743>`_.
-
-Cascade Merge with Bi-directional Associations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are two bugs now that concern the use of cascade merge in combination with bi-directional associations.
-Make sure to study the behavior of cascade merge if you are using it:
-
--  `DDC-875 <https://github.com/doctrine/orm/issues/5398>`_ Merge can sometimes add the same entity twice into a collection
--  `DDC-763 <https://github.com/doctrine/orm/issues/5277>`_ Cascade merge on associated entities can insert too many rows through "Persistence by Reachability"
-
-Custom Persisters
-~~~~~~~~~~~~~~~~~
-
-A Persister in Doctrine is an object that is responsible for the
-hydration and write operations of an entity against the database.
-Currently there is no way to overwrite the persister implementation
-for a given entity, however there are several use-cases that can
-benefit from custom persister implementations:
-
--  `Add Upsert Support <https://github.com/doctrine/orm/issues/5178>`_
--  `Evaluate possible ways in which stored-procedures can be used <https://github.com/doctrine/orm/issues/4946>`_
-
-Persist Keys of Collections
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-PHP Arrays are ordered hash-maps and so should be the
-``Doctrine\Common\Collections\Collection`` interface. We plan to
-evaluate a feature that optionally persists and hydrates the keys
-of a Collection instance.
-
-`Ticket DDC-213 <https://github.com/doctrine/orm/issues/2817>`_
-
-Mapping many tables to one entity
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-It is not possible to map several equally looking tables onto one
-entity. For example if you have a production and an archive table
-of a certain business concept then you cannot have both tables map
-to the same entity.
-
-Behaviors
-~~~~~~~~~
-
-Doctrine ORM will **never** include a behavior system like Doctrine 1
-in the core library. We don't think behaviors add more value than
-they cost pain and debugging hell. Please see the many different
-blog posts we have written on this topics:
-
--  `Doctrine2 "Behaviors" in a Nutshell <http://www.doctrine-project.org/2010/02/17/doctrine2-behaviours-nutshell.html>`_
--  `A re-usable Versionable behavior for Doctrine2 <http://www.doctrine-project.org/2010/02/24/doctrine2-versionable.html>`_
--  `Write your own ORM on top of Doctrine2 <http://www.doctrine-project.org/2010/07/19/your-own-orm-doctrine2.html>`_
--  `Doctrine ORM Behavioral Extensions <http://www.doctrine-project.org/2010/11/18/doctrine2-behavioral-extensions.html>`_
-
-Doctrine ORM has enough hooks and extension points so that **you** can
-add whatever you want on top of it. None of this will ever become
-core functionality of Doctrine2 however, you will have to rely on
-third party extensions for magical behaviors.
-
-Nested Set
-~~~~~~~~~~
-
-NestedSet was offered as a behavior in Doctrine 1 and will not be
-included in the core of Doctrine ORM. However there are already two
-extensions out there that offer support for Nested Set with
-ORM:
-
-
--  `Doctrine2 Hierarchical-Structural Behavior <http://github.com/guilhermeblanco/Doctrine2-Hierarchical-Structural-Behavior>`_
--  `Doctrine2 NestedSet <http://github.com/blt04/doctrine2-nestedset>`_
-
-Known Issues
-------------
-
-The Known Issues section describes critical/blocker bugs and other
-issues that are either complicated to fix, not fixable due to
-backwards compatibility issues or where no simple fix exists (yet).
-We don't plan to add every bug in the tracker there, just those
-issues that can potentially cause nightmares or pain of any sort.
-
-See bugs, improvement and feature requests on `Github issues <https://github.com/doctrine/orm/issues>`_.
-
-Identifier Quoting and Legacy Databases
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-For compatibility reasons between all the supported vendors and
-edge case problems Doctrine ORM does **NOT** do automatic identifier
-quoting. This can lead to problems when trying to get
-legacy-databases to work with Doctrine ORM.
-
-
--  You can quote column-names as described in the
-   :doc:`Basic-Mapping <basic-mapping>` section.
--  You cannot quote join column names.
--  You cannot use non [a-zA-Z0-9\_]+ characters, they will break
-   several SQL statements.
-
-Having problems with these kind of column names? Many databases
-support all CRUD operations on views that semantically map to
-certain tables. You can create views for all your problematic
-tables and column names to avoid the legacy quoting nightmare.
-
-Microsoft SQL Server and Doctrine "datetime"
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Doctrine assumes that you use ``DateTime2`` data-types. If your legacy database contains DateTime
-datatypes then you have to add your own data-type (see Basic Mapping for an example).
-
-MySQL with MyISAM tables
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Doctrine cannot provide atomic operations when calling ``EntityManager#flush()`` if one
-of the tables involved uses the storage engine MyISAM. You must use InnoDB or
-other storage engines that support transactions if you need integrity.
-
-Entities, Proxies and Reflection
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Using methods for Reflection on entities can be prone to error, when the entity
-is actually a proxy the following methods will not work correctly:
-
-- ``new ReflectionClass``
-- ``new ReflectionObject``
-- ``get_class()``
-- ``get_parent_class()``
-
-This is why ``Doctrine\Common\Util\ClassUtils`` class exists that has similar
-methods, which resolve the proxy problem beforehand.
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Common\Util\ClassUtils;
-
-    $bookProxy = $entityManager->getReference('Acme\Book');
-
-    $reflection = ClassUtils::newReflectionClass($bookProxy);
-    $class = ClassUtils::getClass($bookProxy)¸

-Metadata Drivers
-================
-
-The heart of an object relational mapper is the mapping information
-that glues everything together. It instructs the EntityManager how
-it should behave when dealing with the different entities.
-
-Core Metadata Drivers
----------------------
-
-Doctrine provides a few different ways for you to specify your
-metadata:
-
-
--  **XML files** (XmlDriver)
--  **Class DocBlock Annotations** (AnnotationDriver)
--  **YAML files** (YamlDriver)
--  **PHP Code in files or static functions** (PhpDriver)
-
-Something important to note about the above drivers is they are all
-an intermediate step to the same end result. The mapping
-information is populated to ``Doctrine\ORM\Mapping\ClassMetadata``
-instances. So in the end, Doctrine only ever has to work with the
-API of the ``ClassMetadata`` class to get mapping information for
-an entity.
-
-.. note::
-
-    The populated ``ClassMetadata`` instances are also cached
-    so in a production environment the parsing and populating only ever
-    happens once. You can configure the metadata cache implementation
-    using the ``setMetadataCacheImpl()`` method on the
-    ``Doctrine\ORM\Configuration`` class:
-
-    .. code-block:: php
-
-        <?php
-        $em->getConfiguration()->setMetadataCacheImpl(new ApcuCache());
-
-
-If you want to use one of the included core metadata drivers you
-just need to configure it. All the drivers are in the
-``Doctrine\ORM\Mapping\Driver`` namespace:
-
-.. code-block:: php
-
-    <?php
-    $driver = new \Doctrine\ORM\Mapping\Driver\XmlDriver('/path/to/mapping/files');
-    $em->getConfiguration()->setMetadataDriverImpl($driver);
-
-Implementing Metadata Drivers
------------------------------
-
-In addition to the included metadata drivers you can very easily
-implement your own. All you need to do is define a class which
-implements the ``Driver`` interface:
-
-.. code-block:: php
-
-    <?php
-    namespace Doctrine\ORM\Mapping\Driver;
-    
-    use Doctrine\ORM\Mapping\ClassMetadataInfo;
-    
-    interface Driver
-    {
-        /**
-         * Loads the metadata for the specified class into the provided container.
-         * 
-         * @param string $className
-         * @param ClassMetadataInfo $metadata
-         */
-        function loadMetadataForClass($className, ClassMetadataInfo $metadata);
-    
-        /**
-         * Gets the names of all mapped classes known to this driver.
-         * 
-         * @return array The names of all mapped classes known to this driver.
-         */
-        function getAllClassNames(); 
-    
-        /**
-         * Whether the class with the specified name should have its metadata loaded.
-         * This is only the case if it is either mapped as an Entity or a
-         * MappedSuperclass.
-         *
-         * @param string $className
-         * @return boolean
-         */
-        function isTransient($className);
-    }
-
-If you want to write a metadata driver to parse information from
-some file format we've made your life a little easier by providing
-the ``AbstractFileDriver`` implementation for you to extend from:
-
-.. code-block:: php
-
-    <?php
-    class MyMetadataDriver extends AbstractFileDriver
-    {
-        /**
-         * {@inheritdoc}
-         */
-        protected $_fileExtension = '.dcm.ext';
-    
-        /**
-         * {@inheritdoc}
-         */
-        public function loadMetadataForClass($className, ClassMetadataInfo $metadata)
-        {
-            $data = $this->_loadMappingFile($file);
-    
-            // populate ClassMetadataInfo instance from $data
-        }
-    
-        /**
-         * {@inheritdoc}
-         */
-        protected function _loadMappingFile($file)
-        {
-            // parse contents of $file and return php data structure
-        }
-    }
-
-.. note::
-
-    When using the ``AbstractFileDriver`` it requires that you
-    only have one entity defined per file and the file named after the
-    class described inside where namespace separators are replaced by
-    periods. So if you have an entity named ``Entities\User`` and you
-    wanted to write a mapping file for your driver above you would need
-    to name the file ``Entities.User.dcm.ext`` for it to be
-    recognized.
-
-
-Now you can use your ``MyMetadataDriver`` implementation by setting
-it with the ``setMetadataDriverImpl()`` method:
-
-.. code-block:: php
-
-    <?php
-    $driver = new MyMetadataDriver('/path/to/mapping/files');
-    $em->getConfiguration()->setMetadataDriverImpl($driver);
-
-ClassMetadata
--------------
-
-The last piece you need to know and understand about metadata in
-Doctrine ORM is the API of the ``ClassMetadata`` classes. You need to
-be familiar with them in order to implement your own drivers but
-more importantly to retrieve mapping information for a certain
-entity when needed.
-
-You have all the methods you need to manually specify the mapping
-information instead of using some mapping file to populate it from.
-The base ``ClassMetadataInfo`` class is responsible for only data
-storage and is not meant for runtime use. It does not require that
-the class actually exists yet so it is useful for describing some
-entity before it exists and using that information to generate for
-example the entities themselves. The class ``ClassMetadata``
-extends ``ClassMetadataInfo`` and adds some functionality required
-for runtime usage and requires that the PHP class is present and
-can be autoloaded.
-
-You can read more about the API of the ``ClassMetadata`` classes in
-the PHP Mapping chapter.
-
-Getting ClassMetadata Instances
--------------------------------
-
-If you want to get the ``ClassMetadata`` instance for an entity in
-your project to programmatically use some mapping information to
-generate some HTML or something similar you can retrieve it through
-the ``ClassMetadataFactory``:
-
-.. code-block:: php
-
-    <?php
-    $cmf = $em->getMetadataFactory();
-    $class = $cmf->getMetadataFor('MyEntityName');
-
-Now you can learn about the entity and use the data stored in the
-``ClassMetadata`` instance to get all mapped fields for example and
-iterate over them:
-
-.. code-block:: php
-
-    <?php
-    foreach ($class->fieldMappings as $fieldMapping) {

-Implementing a NamingStrategy
-==============================
-
-Using a naming strategy you can provide rules for generating database identifiers,
-column or table names. This feature helps
-reduce the verbosity of the mapping document, eliminating repetitive noise (eg: ``TABLE_``).
-
-.. warning
-
-    The naming strategy is always overridden by entity mapping such as the `Table` annotation.
-
-Configuring a naming strategy
------------------------------
-The default strategy used by Doctrine is quite minimal.
-
-By default the ``Doctrine\ORM\Mapping\DefaultNamingStrategy``
-uses the simple class name and the attribute names to generate tables and columns.
-
-You can specify a different strategy by calling ``Doctrine\ORM\Configuration#setNamingStrategy()``:
-
-.. code-block:: php
-
-    <?php
-    $namingStrategy = new MyNamingStrategy();
-    $configuration->setNamingStrategy($namingStrategy);
-
-Underscore naming strategy
----------------------------
-
-``\Doctrine\ORM\Mapping\UnderscoreNamingStrategy`` is a built-in strategy.
-
-.. code-block:: php
-
-    <?php
-    $namingStrategy = new \Doctrine\ORM\Mapping\UnderscoreNamingStrategy(CASE_UPPER);
-    $configuration->setNamingStrategy($namingStrategy);
-
-For SomeEntityName the strategy will generate the table SOME_ENTITY_NAME with the
-``CASE_UPPER`` option, or some_entity_name with the ``CASE_LOWER`` option.
-
-Naming strategy interface
--------------------------
-The interface ``Doctrine\ORM\Mapping\NamingStrategy`` allows you to specify
-a naming strategy for database tables and columns.
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Return a table name for an entity class
-     *
-     * @param string $className The fully-qualified class name
-     * @return string A table name
-     */
-    function classToTableName($className);
-
-    /**
-     * Return a column name for a property
-     *
-     * @param string $propertyName A property
-     * @return string A column name
-     */
-    function propertyToColumnName($propertyName);
-
-    /**
-     * Return the default reference column name
-     *
-     * @return string A column name
-     */
-    function referenceColumnName();
-
-    /**
-     * Return a join column name for a property
-     *
-     * @param string $propertyName A property
-     * @return string A join column name
-     */
-    function joinColumnName($propertyName, $className = null);
-
-    /**
-     * Return a join table name
-     *
-     * @param string $sourceEntity The source entity
-     * @param string $targetEntity The target entity
-     * @param string $propertyName A property
-     * @return string A join table name
-     */
-    function joinTableName($sourceEntity, $targetEntity, $propertyName = null);
-
-    /**
-     * Return the foreign key column name for the given parameters
-     *
-     * @param string $entityName A entity
-     * @param string $referencedColumnName A property
-     * @return string A join column name
-     */
-    function joinKeyColumnName($entityName, $referencedColumnName = null);
-
-Implementing a naming strategy
--------------------------------
-If you have database naming standards, like all table names should be prefixed
-by the application prefix, all column names should be lower case, you can easily
-achieve such standards by implementing a naming strategy.
-
-You need to create a class which implements ``Doctrine\ORM\Mapping\NamingStrategy``.
-
-
-.. code-block:: php
-
-    <?php
-    class MyAppNamingStrategy implements NamingStrategy
-    {
-        public function classToTableName($className)
-        {
-            return 'MyApp_' . substr($className, strrpos($className, '\\') + 1);
-        }
-        public function propertyToColumnName($propertyName)
-        {
-            return $propertyName;
-        }
-        public function referenceColumnName()
-        {
-            return 'id';
-        }
-        public function joinColumnName($propertyName, $className = null)
-        {
-            return $propertyName . '_' . $this->referenceColumnName();
-        }
-        public function joinTableName($sourceEntity, $targetEntity, $propertyName = null)
-        {
-            return strtolower($this->classToTableName($sourceEntity) . '_' .
-                    $this->classToTableName($targetEntity));
-        }

-Native SQL
-==========
-
-With ``NativeQuery`` you can execute native SELECT SQL statements
-and map the results to Doctrine entities or any other result format
-supported by Doctrine.
-
-In order to make this mapping possible, you need to describe
-to Doctrine what columns in the result map to which entity property.
-This description is represented by a ``ResultSetMapping`` object.
-
-With this feature you can map arbitrary SQL code to objects, such as highly
-vendor-optimized SQL or stored-procedures.
-
-Writing ``ResultSetMapping`` from scratch is complex, but there is a convenience
-wrapper around it called a ``ResultSetMappingBuilder``. It can generate
-the mappings for you based on Entities and even generates the ``SELECT``
-clause based on this information for you.
-
-.. note::
-
-    If you want to execute DELETE, UPDATE or INSERT statements
-    the Native SQL API cannot be used and will probably throw errors.
-    Use ``EntityManager#getConnection()`` to access the native database
-    connection and call the ``executeUpdate()`` method for these
-    queries.
-
-The NativeQuery class
----------------------
-
-To create a ``NativeQuery`` you use the method
-``EntityManager#createNativeQuery($sql, $resultSetMapping)``. As you can see in
-the signature of this method, it expects 2 ingredients: The SQL you want to
-execute and the ``ResultSetMapping`` that describes how the results will be
-mapped.
-
-Once you obtained an instance of a ``NativeQuery``, you can bind parameters to
-it with the same API that ``Query`` has and execute it.
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Query\ResultSetMapping;
-
-    $rsm = new ResultSetMapping();
-    // build rsm here
-
-    $query = $entityManager->createNativeQuery('SELECT id, name, discr FROM users WHERE name = ?', $rsm);
-    $query->setParameter(1, 'romanb');
-
-    $users = $query->getResult();
-
-ResultSetMappingBuilder
------------------------
-
-An easy start into ResultSet mapping is the ``ResultSetMappingBuilder`` object.
-This has several benefits:
-
-- The builder takes care of automatically updating your ``ResultSetMapping``
-  when the fields or associations change on the metadata of an entity.
-- You can generate the required ``SELECT`` expression for a builder
-  by converting it to a string.
-- The API is much simpler than the usual ``ResultSetMapping`` API.
-
-One downside is that the builder API does not yet support entities
-with inheritance hierarchies.
-
-.. code-block:: php
-
-    <?php
-
-    use Doctrine\ORM\Query\ResultSetMappingBuilder;
-
-    $sql = "SELECT u.id, u.name, a.id AS address_id, a.street, a.city " . 
-           "FROM users u INNER JOIN address a ON u.address_id = a.id";
-
-    $rsm = new ResultSetMappingBuilder($entityManager);
-    $rsm->addRootEntityFromClassMetadata('MyProject\User', 'u');
-    $rsm->addJoinedEntityFromClassMetadata('MyProject\Address', 'a', 'u', 'address', array('id' => 'address_id'));
-
-The builder extends the ``ResultSetMapping`` class and as such has all the functionality of it as well.
-
-The ``SELECT`` clause can be generated
-from a ``ResultSetMappingBuilder``. You can either cast the builder
-object to ``(string)`` and the DQL aliases are used as SQL table aliases
-or use the ``generateSelectClause($tableAliases)`` method and pass
-a mapping from DQL alias (key) to SQL alias (value)
-
-.. code-block:: php
-
-    <?php
-
-    $selectClause = $rsm->generateSelectClause(array(
-        'u' => 't1',
-        'g' => 't2'
-    ));
-    $sql = "SELECT " . $selectClause . " FROM users t1 JOIN groups t2 ON t1.group_id = t2.id";
-
-
-The ResultSetMapping
---------------------
-
-Understanding the ``ResultSetMapping`` is the key to using a
-``NativeQuery``. A Doctrine result can contain the following
-components:
-
-
--  Entity results. These represent root result elements.
--  Joined entity results. These represent joined entities in
-   associations of root entity results.
--  Field results. These represent a column in the result set that
-   maps to a field of an entity. A field result always belongs to an
-   entity result or joined entity result.
--  Scalar results. These represent scalar values in the result set
-   that will appear in each result row. Adding scalar results to a
-   ResultSetMapping can also cause the overall result to become
-   **mixed** (see DQL - Doctrine Query Language) if the same
-   ResultSetMapping also contains entity results.
--  Meta results. These represent columns that contain
-   meta-information, such as foreign keys and discriminator columns.
-   When querying for objects (``getResult()``), all meta columns of
-   root entities or joined entities must be present in the SQL query
-   and mapped accordingly using ``ResultSetMapping#addMetaResult``.
-
-.. note::
-
-    It might not surprise you that Doctrine uses
-    ``ResultSetMapping`` internally when you create DQL queries. As
-    the query gets parsed and transformed to SQL, Doctrine fills a
-    ``ResultSetMapping`` that describes how the results should be
-    processed by the hydration routines.
-
-
-We will now look at each of the result types that can appear in a
-ResultSetMapping in detail.
-
-Entity results
-~~~~~~~~~~~~~~
-
-An entity result describes an entity type that appears as a root
-element in the transformed result. You add an entity result through
-``ResultSetMapping#addEntityResult()``. Let's take a look at the
-method signature in detail:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Adds an entity result to this ResultSetMapping.
-     *
-     * @param string $class The class name of the entity.
-     * @param string $alias The alias for the class. The alias must be unique among all entity
-     *                      results or joined entity results within this ResultSetMapping.
-     */
-    public function addEntityResult($class, $alias)
-
-The first parameter is the fully qualified name of the entity
-class. The second parameter is some arbitrary alias for this entity
-result that must be unique within a ``ResultSetMapping``. You use
-this alias to attach field results to the entity result. It is very
-similar to an identification variable that you use in DQL to alias
-classes or relationships.
-
-An entity result alone is not enough to form a valid
-``ResultSetMapping``. An entity result or joined entity result
-always needs a set of field results, which we will look at soon.
-
-Joined entity results
-~~~~~~~~~~~~~~~~~~~~~
-
-A joined entity result describes an entity type that appears as a
-joined relationship element in the transformed result, attached to
-a (root) entity result. You add a joined entity result through
-``ResultSetMapping#addJoinedEntityResult()``. Let's take a look at
-the method signature in detail:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Adds a joined entity result.
-     *
-     * @param string $class The class name of the joined entity.
-     * @param string $alias The unique alias to use for the joined entity.
-     * @param string $parentAlias The alias of the entity result that is the parent of this joined result.
-     * @param object $relation The association field that connects the parent entity result with the joined entity result.
-     */
-    public function addJoinedEntityResult($class, $alias, $parentAlias, $relation)
-
-The first parameter is the class name of the joined entity. The
-second parameter is an arbitrary alias for the joined entity that
-must be unique within the ``ResultSetMapping``. You use this alias
-to attach field results to the entity result. The third parameter
-is the alias of the entity result that is the parent type of the
-joined relationship. The fourth and last parameter is the name of
-the field on the parent entity result that should contain the
-joined entity result.
-
-Field results
-~~~~~~~~~~~~~
-
-A field result describes the mapping of a single column in a SQL
-result set to a field in an entity. As such, field results are
-inherently bound to entity results. You add a field result through
-``ResultSetMapping#addFieldResult()``. Again, let's examine the
-method signature in detail:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Adds a field result that is part of an entity result or joined entity result.
-     *
-     * @param string $alias The alias of the entity result or joined entity result.
-     * @param string $columnName The name of the column in the SQL result set.
-     * @param string $fieldName The name of the field on the (joined) entity.
-     */
-    public function addFieldResult($alias, $columnName, $fieldName)
-
-The first parameter is the alias of the entity result to which the
-field result will belong. The second parameter is the name of the
-column in the SQL result set. Note that this name is case
-sensitive, i.e. if you use a native query against Oracle it must be
-all uppercase. The third parameter is the name of the field on the
-entity result identified by ``$alias`` into which the value of the
-column should be set.
-
-Scalar results
-~~~~~~~~~~~~~~
-
-A scalar result describes the mapping of a single column in a SQL
-result set to a scalar value in the Doctrine result. Scalar results
-are typically used for aggregate values but any column in the SQL
-result set can be mapped as a scalar value. To add a scalar result
-use ``ResultSetMapping#addScalarResult()``. The method signature in
-detail:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Adds a scalar result mapping.
-     *
-     * @param string $columnName The name of the column in the SQL result set.
-     * @param string $alias The result alias with which the scalar result should be placed in the result structure.
-     */
-    public function addScalarResult($columnName, $alias)
-
-The first parameter is the name of the column in the SQL result set
-and the second parameter is the result alias under which the value
-of the column will be placed in the transformed Doctrine result.
-
-Meta results
-~~~~~~~~~~~~
-
-A meta result describes a single column in a SQL result set that
-is either a foreign key or a discriminator column. These columns
-are essential for Doctrine to properly construct objects out of SQL
-result sets. To add a column as a meta result use
-``ResultSetMapping#addMetaResult()``. The method signature in
-detail:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Adds a meta column (foreign key or discriminator column) to the result set.
-     * 
-     * @param string  $alias
-     * @param string  $columnAlias
-     * @param string  $columnName
-     * @param boolean $isIdentifierColumn
-     */
-    public function addMetaResult($alias, $columnAlias, $columnName, $isIdentifierColumn = false)
-
-The first parameter is the alias of the entity result to which the
-meta column belongs. A meta result column (foreign key or
-discriminator column) always belongs to an entity result. The
-second parameter is the column alias/name of the column in the SQL
-result set and the third parameter is the column name used in the
-mapping.
-The fourth parameter should be set to true in case the primary key
-of the entity is the foreign key you're adding.
-
-Discriminator Column
-~~~~~~~~~~~~~~~~~~~~
-
-When joining an inheritance tree you have to give Doctrine a hint
-which meta-column is the discriminator column of this tree.
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Sets a discriminator column for an entity result or joined entity result.
-     * The discriminator column will be used to determine the concrete class name to
-     * instantiate.
-     *
-     * @param string $alias The alias of the entity result or joined entity result the discriminator
-     *                      column should be used for.
-     * @param string $discrColumn The name of the discriminator column in the SQL result set.
-     */
-    public function setDiscriminatorColumn($alias, $discrColumn)
-
-Examples
-~~~~~~~~
-
-Understanding a ResultSetMapping is probably easiest through
-looking at some examples.
-
-First a basic example that describes the mapping of a single
-entity.
-
-.. code-block:: php
-
-    <?php
-    // Equivalent DQL query: "select u from User u where u.name=?1"
-    // User owns no associations.
-    $rsm = new ResultSetMapping;
-    $rsm->addEntityResult('User', 'u');
-    $rsm->addFieldResult('u', 'id', 'id');
-    $rsm->addFieldResult('u', 'name', 'name');
-    
-    $query = $this->_em->createNativeQuery('SELECT id, name FROM users WHERE name = ?', $rsm);
-    $query->setParameter(1, 'romanb');
-    
-    $users = $query->getResult();
-
-The result would look like this:
-
-.. code-block:: php
-
-    array(
-        [0] => User (Object)
-    )
-
-Note that this would be a partial object if the entity has more
-fields than just id and name. In the example above the column and
-field names are identical but that is not necessary, of course.
-Also note that the query string passed to createNativeQuery is
-**real native SQL**. Doctrine does not touch this SQL in any way.
-
-In the previous basic example, a User had no relations and the
-table the class is mapped to owns no foreign keys. The next example
-assumes User has a unidirectional or bidirectional one-to-one
-association to a CmsAddress, where the User is the owning side and
-thus owns the foreign key.
-
-.. code-block:: php
-
-    <?php
-    // Equivalent DQL query: "select u from User u where u.name=?1"
-    // User owns an association to an Address but the Address is not loaded in the query.
-    $rsm = new ResultSetMapping;
-    $rsm->addEntityResult('User', 'u');
-    $rsm->addFieldResult('u', 'id', 'id');
-    $rsm->addFieldResult('u', 'name', 'name');
-    $rsm->addMetaResult('u', 'address_id', 'address_id');
-    
-    $query = $this->_em->createNativeQuery('SELECT id, name, address_id FROM users WHERE name = ?', $rsm);
-    $query->setParameter(1, 'romanb');
-    
-    $users = $query->getResult();
-
-Foreign keys are used by Doctrine for lazy-loading purposes when
-querying for objects. In the previous example, each user object in
-the result will have a proxy (a "ghost") in place of the address
-that contains the address\_id. When the ghost proxy is accessed, it
-loads itself based on this key.
-
-Consequently, associations that are *fetch-joined* do not require
-the foreign keys to be present in the SQL result set, only
-associations that are lazy.
-
-.. code-block:: php
-
-    <?php
-    // Equivalent DQL query: "select u from User u join u.address a WHERE u.name = ?1"
-    // User owns association to an Address and the Address is loaded in the query.
-    $rsm = new ResultSetMapping;
-    $rsm->addEntityResult('User', 'u');
-    $rsm->addFieldResult('u', 'id', 'id');
-    $rsm->addFieldResult('u', 'name', 'name');
-    $rsm->addJoinedEntityResult('Address' , 'a', 'u', 'address');
-    $rsm->addFieldResult('a', 'address_id', 'id');
-    $rsm->addFieldResult('a', 'street', 'street');
-    $rsm->addFieldResult('a', 'city', 'city');
-    
-    $sql = 'SELECT u.id, u.name, a.id AS address_id, a.street, a.city FROM users u ' .
-           'INNER JOIN address a ON u.address_id = a.id WHERE u.name = ?';
-    $query = $this->_em->createNativeQuery($sql, $rsm);
-    $query->setParameter(1, 'romanb');
-    
-    $users = $query->getResult();
-
-In this case the nested entity ``Address`` is registered with the
-``ResultSetMapping#addJoinedEntityResult`` method, which notifies
-Doctrine that this entity is not hydrated at the root level, but as
-a joined entity somewhere inside the object graph. In this case we
-specify the alias 'u' as third parameter and ``address`` as fourth
-parameter, which means the ``Address`` is hydrated into the
-``User::$address`` property.
-
-If a fetched entity is part of a mapped hierarchy that requires a
-discriminator column, this column must be present in the result set
-as a meta column so that Doctrine can create the appropriate
-concrete type. This is shown in the following example where we
-assume that there are one or more subclasses that extend User and
-either Class Table Inheritance or Single Table Inheritance is used
-to map the hierarchy (both use a discriminator column).
-
-.. code-block:: php
-
-    <?php
-    // Equivalent DQL query: "select u from User u where u.name=?1"
-    // User is a mapped base class for other classes. User owns no associations.
-    $rsm = new ResultSetMapping;
-    $rsm->addEntityResult('User', 'u');
-    $rsm->addFieldResult('u', 'id', 'id');
-    $rsm->addFieldResult('u', 'name', 'name');
-    $rsm->addMetaResult('u', 'discr', 'discr'); // discriminator column
-    $rsm->setDiscriminatorColumn('u', 'discr');
-    
-    $query = $this->_em->createNativeQuery('SELECT id, name, discr FROM users WHERE name = ?', $rsm);
-    $query->setParameter(1, 'romanb');
-    
-    $users = $query->getResult();
-
-Note that in the case of Class Table Inheritance, an example as
-above would result in partial objects if any objects in the result
-are actually a subtype of User. When using DQL, Doctrine
-automatically includes the necessary joins for this mapping
-strategy but with native SQL it is your responsibility.
-
-Named Native Query
-------------------
-
-You can also map a native query using a named native query mapping.
-
-To achieve that, you must describe the SQL resultset structure
-using named native query (and sql resultset mappings if is a several resultset mappings).
-
-Like named query, a named native query can be defined at class level or in a XML or YAML file.
-
-
-A resultSetMapping parameter is defined in @NamedNativeQuery,
-it represents the name of a defined @SqlResultSetMapping.
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        namespace MyProject\Model;
-        /**

-Things to note:
-    - The resultset mapping declares the entities retrieved by this native query.
-    - Each field of the entity is bound to a SQL alias (or column name).
-    - All fields of the entity including the ones of subclasses
-      and the foreign key columns of related entities have to be present in the SQL query.
-    - Field definitions are optional provided that they map to the same
-      column name as the one declared on the class property.
-    - ``__CLASS__`` is an alias for the mapped class
-
-
-In the above example,
-the ``fetchJoinedAddress`` named query use the joinMapping result set mapping.
-This mapping returns 2 entities, User and Address, each property is declared and associated to a column name,
-actually the column name retrieved by the query.
-
-Let's now see an implicit declaration of the property / column.

-In this example, we only describe the entity member of the result set mapping.
-The property / column mappings is done using the entity mapping values.
-In this case the model property is bound to the model_txt column.
-If the association to a related entity involve a composite primary key,
-a @FieldResult element should be used for each foreign key column.
-The @FieldResult name is composed of the property name for the relationship,
-followed by a dot ("."), followed by the name or the field or property of the primary key.

-Partial Objects
-===============
-
-A partial object is an object whose state is not fully initialized
-after being reconstituted from the database and that is
-disconnected from the rest of its data. The following section will
-describe why partial objects are problematic and what the approach
-of Doctrine2 to this problem is.
-
-.. note::
-
-    The partial object problem in general does not apply to
-    methods or queries where you do not retrieve the query result as
-    objects. Examples are: ``Query#getArrayResult()``,
-    ``Query#getScalarResult()``, ``Query#getSingleScalarResult()``,
-    etc.
-
-.. warning::
-
-    Use of partial objects is tricky. Fields that are not retrieved
-    from the database will not be updated by the UnitOfWork even if they
-    get changed in your objects. You can only promote a partial object
-    to a fully-loaded object by calling ``EntityManager#refresh()``
-    or a DQL query with the refresh flag.
-
-
-What is the problem?
---------------------
-
-In short, partial objects are problematic because they are usually
-objects with broken invariants. As such, code that uses these
-partial objects tends to be very fragile and either needs to "know"
-which fields or methods can be safely accessed or add checks around
-every field access or method invocation. The same holds true for
-the internals, i.e. the method implementations, of such objects.
-You usually simply assume the state you need in the method is
-available, after all you properly constructed this object before
-you pushed it into the database, right? These blind assumptions can
-quickly lead to null reference errors when working with such
-partial objects.
-
-It gets worse with the scenario of an optional association (0..1 to
-1). When the associated field is NULL, you don't know whether this
-object does not have an associated object or whether it was simply
-not loaded when the owning object was loaded from the database.
-
-These are reasons why many ORMs do not allow partial objects at all
-and instead you always have to load an object with all its fields
-(associations being proxied). One secure way to allow partial
-objects is if the programming language/platform allows the ORM tool
-to hook deeply into the object and instrument it in such a way that
-individual fields (not only associations) can be loaded lazily on
-first access. This is possible in Java, for example, through
-bytecode instrumentation. In PHP though this is not possible, so
-there is no way to have "secure" partial objects in an ORM with
-transparent persistence.
-
-Doctrine, by default, does not allow partial objects. That means,
-any query that only selects partial object data and wants to
-retrieve the result as objects (i.e. ``Query#getResult()``) will
-raise an exception telling you that partial objects are dangerous.
-If you want to force a query to return you partial objects,
-possibly as a performance tweak, you can use the ``partial``
-keyword as follows:
-
-.. code-block:: php
-
-    <?php
-    $q = $em->createQuery("select partial u.{id,name} from MyApp\Domain\User u");
-
-You can also get a partial reference instead of a proxy reference by
-calling:
-
-.. code-block:: php
-
-    <?php
-    $reference = $em->getPartialReference('MyApp\Domain\User', 1);
-
-Partial references are objects with only the identifiers set as they
-are passed to the second argument of the ``getPartialReference()`` method.
-All other fields are null.
-
-When should I force partial objects?
-------------------------------------
-
-Mainly for optimization purposes, but be careful of premature
-optimization as partial objects lead to potentially more fragile
-code.

-PHP Mapping
-===========
-
-Doctrine ORM also allows you to provide the ORM metadata in the form
-of plain PHP code using the ``ClassMetadata`` API. You can write
-the code in PHP files or inside of a static function named
-``loadMetadata($class)`` on the entity class itself.
-
-PHP Files
----------
-
-If you wish to write your mapping information inside PHP files that
-are named after the entity and included to populate the metadata
-for an entity you can do so by using the ``PHPDriver``:
-
-.. code-block:: php
-
-    <?php
-    $driver = new PHPDriver('/path/to/php/mapping/files');
-    $em->getConfiguration()->setMetadataDriverImpl($driver);
-
-Now imagine we had an entity named ``Entities\User`` and we wanted
-to write a mapping file for it using the above configured
-``PHPDriver`` instance:
-
-.. code-block:: php
-
-    <?php
-    namespace Entities;
-
-    class User
-    {
-        private $id;
-        private $username;
-    }
-
-To write the mapping information you just need to create a file
-named ``Entities.User.php`` inside of the
-``/path/to/php/mapping/files`` folder:
-
-.. code-block:: php
-
-    <?php
-    // /path/to/php/mapping/files/Entities.User.php
-
-    $metadata->mapField(array(
-       'id' => true,
-       'fieldName' => 'id',
-       'type' => 'integer'
-    ));
-
-    $metadata->mapField(array(
-       'fieldName' => 'username',
-       'type' => 'string',
-       'options' => array(
-           'fixed' => true,
-           'comment' => "User's login name"
-       )
-    ));
-
-    $metadata->mapField(array(
-       'fieldName' => 'login_count',
-       'type' => 'integer',
-       'nullable' => false,
-       'options' => array(
-           'unsigned' => true,
-           'default' => 0
-       )
-    ));
-
-Now we can easily retrieve the populated ``ClassMetadata`` instance
-where the ``PHPDriver`` includes the file and the
-``ClassMetadataFactory`` caches it for later retrieval:
-
-.. code-block:: php
-
-    <?php
-    $class = $em->getClassMetadata('Entities\User');
-    // or
-    $class = $em->getMetadataFactory()->getMetadataFor('Entities\User');
-
-Static Function
----------------
-
-In addition to the PHP files you can also specify your mapping
-information inside of a static function defined on the entity class
-itself. This is useful for cases where you want to keep your entity
-and mapping information together but don't want to use annotations.
-For this you just need to use the ``StaticPHPDriver``:
-
-.. code-block:: php
-
-    <?php
-    $driver = new StaticPHPDriver('/path/to/entities');
-    $em->getConfiguration()->setMetadataDriverImpl($driver);
-
-Now you just need to define a static function named
-``loadMetadata($metadata)`` on your entity:
-
-.. code-block:: php
-
-    <?php
-    namespace Entities;
-
-    use Doctrine\ORM\Mapping\ClassMetadata;
-
-    class User
-    {
-        // ...
-
-        public static function loadMetadata(ClassMetadata $metadata)
-        {
-            $metadata->mapField(array(
-               'id' => true,
-               'fieldName' => 'id',
-               'type' => 'integer'
-            ));
-
-            $metadata->mapField(array(
-               'fieldName' => 'username',
-               'type' => 'string'
-            ));
-        }
-    }
-
-ClassMetadataBuilder
---------------------
-
-To ease the use of the ClassMetadata API (which is very raw) there is a ``ClassMetadataBuilder`` that you can use.
-
-.. code-block:: php
-
-    <?php
-    namespace Entities;
-
-    use Doctrine\ORM\Mapping\ClassMetadata;
-    use Doctrine\ORM\Mapping\Builder\ClassMetadataBuilder;
-
-    class User
-    {
-        // ...
-
-        public static function loadMetadata(ClassMetadata $metadata)
-        {
-            $builder = new ClassMetadataBuilder($metadata);
-            $builder->createField('id', 'integer')->isPrimaryKey()->generatedValue()->build();
-            $builder->addField('username', 'string');
-        }
-    }
-
-The API of the ClassMetadataBuilder has the following methods with a fluent interface:
-
--   ``addField($name, $type, array $mapping)``
--   ``setMappedSuperclass()``
--   ``setReadOnly()``
--   ``setCustomRepositoryClass($className)``
--   ``setTable($name)``
--   ``addIndex(array $columns, $indexName)``
--   ``addUniqueConstraint(array $columns, $constraintName)``
--   ``addNamedQuery($name, $dqlQuery)``
--   ``setJoinedTableInheritance()``
--   ``setSingleTableInheritance()``
--   ``setDiscriminatorColumn($name, $type = 'string', $length = 255)``
--   ``addDiscriminatorMapClass($name, $class)``
--   ``setChangeTrackingPolicyDeferredExplicit()``
--   ``setChangeTrackingPolicyNotify()``
--   ``addLifecycleEvent($methodName, $event)``
--   ``addManyToOne($name, $targetEntity, $inversedBy = null)``
--   ``addInverseOneToOne($name, $targetEntity, $mappedBy)``
--   ``addOwningOneToOne($name, $targetEntity, $inversedBy = null)``
--   ``addOwningManyToMany($name, $targetEntity, $inversedBy = null)``
--   ``addInverseManyToMany($name, $targetEntity, $mappedBy)``
--   ``addOneToMany($name, $targetEntity, $mappedBy)``
-
-It also has several methods that create builders (which are necessary for advanced mappings):
-
--   ``createField($name, $type)`` returns a ``FieldBuilder`` instance
--   ``createManyToOne($name, $targetEntity)`` returns an ``AssociationBuilder`` instance
--   ``createOneToOne($name, $targetEntity)`` returns an ``AssociationBuilder`` instance
--   ``createManyToMany($name, $targetEntity)`` returns an ``ManyToManyAssociationBuilder`` instance
--   ``createOneToMany($name, $targetEntity)`` returns an ``OneToManyAssociationBuilder`` instance
-
-ClassMetadataInfo API

-The ``ClassMetadataInfo`` class is the base data object for storing
-the mapping metadata for a single entity. It contains all the
-getters and setters you need populate and retrieve information for
-an entity.

-The QueryBuilder
-================
-
-A ``QueryBuilder`` provides an API that is designed for
-conditionally constructing a DQL query in several steps.
-
-It provides a set of classes and methods that is able to
-programmatically build queries, and also provides a fluent API.
-This means that you can change between one methodology to the other
-as you want, or just pick a preferred one.
-
-.. note::
-
-    The ``QueryBuilder`` is not an abstraction of DQL, but merely a tool to dynamically build it.
-    You should still use plain DQL when you can, as it is simpler and more readable.
-    More about this in the :doc:`FAQ <faq>`_.
-
-Constructing a new QueryBuilder object
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The same way you build a normal Query, you build a ``QueryBuilder``
-object. Here is an example of how to build a ``QueryBuilder``
-object:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-
-    // example1: creating a QueryBuilder instance
-    $qb = $em->createQueryBuilder();
-
-An instance of QueryBuilder has several informative methods.  One
-good example is to inspect what type of object the
-``QueryBuilder`` is.
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    // example2: retrieving type of QueryBuilder
-    echo $qb->getType(); // Prints: 0
-
-There're currently 3 possible return values for ``getType()``:
-
-
--  ``QueryBuilder::SELECT``, which returns value 0
--  ``QueryBuilder::DELETE``, returning value 1
--  ``QueryBuilder::UPDATE``, which returns value 2
-
-It is possible to retrieve the associated ``EntityManager`` of the
-current ``QueryBuilder``, its DQL and also a ``Query`` object when
-you finish building your DQL.
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    // example3: retrieve the associated EntityManager
-    $em = $qb->getEntityManager();
-
-    // example4: retrieve the DQL string of what was defined in QueryBuilder
-    $dql = $qb->getDql();
-
-    // example5: retrieve the associated Query object with the processed DQL
-    $q = $qb->getQuery();
-
-Internally, ``QueryBuilder`` works with a DQL cache to increase
-performance. Any changes that may affect the generated DQL actually
-modifies the state of ``QueryBuilder`` to a stage we call
-STATE\_DIRTY. One ``QueryBuilder`` can be in two different states:
-
-
--  ``QueryBuilder::STATE_CLEAN``, which means DQL haven't been
-   altered since last retrieval or nothing were added since its
-   instantiation
--  ``QueryBuilder::STATE_DIRTY``, means DQL query must (and will)
-   be processed on next retrieval
-
-Working with QueryBuilder
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-
-High level API methods
-^^^^^^^^^^^^^^^^^^^^^^
-
-The most straightforward way to build a dynamic query with the ``QueryBuilder`` is by taking
-advantage of Helper methods. For all base code, there is a set of
-useful methods to simplify a programmer's life. To illustrate how
-to work with them, here is the same example 6 re-written using
-``QueryBuilder`` helper methods:
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    $qb->select('u')
-       ->from('User', 'u')
-       ->where('u.id = ?1')
-       ->orderBy('u.name', 'ASC');
-
-``QueryBuilder`` helper methods are considered the standard way to
-use the ``QueryBuilder``. The ``$qb->expr()->*`` methods can help you
-build conditional expressions dynamically. Here is a converted example 8 to
-suggested way to build queries with dynamic conditions:
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    $qb->select(array('u')) // string 'u' is converted to array internally
-       ->from('User', 'u')
-       ->where($qb->expr()->orX(
-           $qb->expr()->eq('u.id', '?1'),
-           $qb->expr()->like('u.nickname', '?2')
-       ))
-       ->orderBy('u.surname', 'ASC');
-
-Here is a complete list of helper methods available in ``QueryBuilder``:
-
-.. code-block:: php
-
-    <?php
-    class QueryBuilder
-    {
-        // Example - $qb->select('u')
-        // Example - $qb->select(array('u', 'p'))
-        // Example - $qb->select($qb->expr()->select('u', 'p'))
-        public function select($select = null);
-
-        // addSelect does not override previous calls to select
-        //
-        // Example - $qb->select('u');
-        //              ->addSelect('p.area_code');
-        public function addSelect($select = null);
-
-        // Example - $qb->delete('User', 'u')
-        public function delete($delete = null, $alias = null);
-
-        // Example - $qb->update('Group', 'g')
-        public function update($update = null, $alias = null);
-
-        // Example - $qb->set('u.firstName', $qb->expr()->literal('Arnold'))
-        // Example - $qb->set('u.numChilds', 'u.numChilds + ?1')
-        // Example - $qb->set('u.numChilds', $qb->expr()->sum('u.numChilds', '?1'))
-        public function set($key, $value);
-
-        // Example - $qb->from('Phonenumber', 'p')
-        // Example - $qb->from('Phonenumber', 'p', 'p.id')
-        public function from($from, $alias, $indexBy = null);
-

-Binding parameters to your query
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Doctrine supports dynamic binding of parameters to your query,
-similar to preparing queries. You can use both strings and numbers
-as placeholders, although both have a slightly different syntax.
-Additionally, you must make your choice: Mixing both styles is not
-allowed. Binding parameters can simply be achieved as follows:
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    $qb->select('u')
-       ->from('User', 'u')
-       ->where('u.id = ?1')
-       ->orderBy('u.name', 'ASC')
-       ->setParameter(1, 100); // Sets ?1 to 100, and thus we will fetch a user with u.id = 100
-
-You are not forced to enumerate your placeholders as the
-alternative syntax is available:
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    $qb->select('u')
-       ->from('User', 'u')
-       ->where('u.id = :identifier')
-       ->orderBy('u.name', 'ASC')
-       ->setParameter('identifier', 100); // Sets :identifier to 100, and thus we will fetch a user with u.id = 100
-
-Note that numeric placeholders start with a ? followed by a number
-while the named placeholders start with a : followed by a string.
-
-Calling ``setParameter()`` automatically infers which type you are setting as
-value. This works for integers, arrays of strings/integers, DateTime instances
-and for managed entities. If you want to set a type explicitly you can call
-the third argument to ``setParameter()`` explicitly. It accepts either a PDO
-type or a DBAL Type name for conversion.
-
-.. note::
-
-    Even though passing DateTime instance is allowed, it impacts performance 
-    as by default there is an attempt to load metadata for object, and if it's not found, 
-    type is inferred from the original value.
-    
-.. code-block:: php
-
-    <?php
-    
-    use Doctrine\DBAL\Types\Types;
-    
-    // prevents attempt to load metadata for date time class, improving performance
-    $qb->setParameter('date', new \DateTimeImmutable(), Types::DATE_IMMUTABLE)
-
-If you've got several parameters to bind to your query, you can
-also use setParameters() instead of setParameter() with the
-following syntax:
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    // Query here...
-    $qb->setParameters(array(1 => 'value for ?1', 2 => 'value for ?2'));
-
-Getting already bound parameters is easy - simply use the above
-mentioned syntax with "getParameter()" or "getParameters()":
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    // See example above
-    $params = $qb->getParameters();
-    // $params instanceof \Doctrine\Common\Collections\ArrayCollection
-
-    // Equivalent to
-    $param = $qb->getParameter(1);
-    // $param instanceof \Doctrine\ORM\Query\Parameter
-
-Note: If you try to get a parameter that was not bound yet,
-getParameter() simply returns NULL.
-
-The API of a Query Parameter is:
-
-.. code-block:: php
-
-    namespace Doctrine\ORM\Query;
-
-    class Parameter
-    {
-        public function getName();
-        public function getValue();
-        public function getType();
-        public function setValue($value, $type = null);
-    }
-
-Limiting the Result
-^^^^^^^^^^^^^^^^^^^
-
-To limit a result the query builder has some methods in common with
-the Query object which can be retrieved from ``EntityManager#createQuery()``.
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-    $offset = (int)$_GET['offset'];
-    $limit = (int)$_GET['limit'];
-
-    $qb->add('select', 'u')
-       ->add('from', 'User u')
-       ->add('orderBy', 'u.name ASC')
-       ->setFirstResult( $offset )
-       ->setMaxResults( $limit );
-
-Executing a Query
-^^^^^^^^^^^^^^^^^
-
-The QueryBuilder is a builder object only -  it has no means of actually
-executing the Query. Additionally a set of parameters such as query hints
-cannot be set on the QueryBuilder itself. This is why you always have to convert
-a querybuilder instance into a Query object:
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-    $query = $qb->getQuery();
-
-    // Set additional Query options
-    $query->setQueryHint('foo', 'bar');
-    $query->useResultCache('my_cache_id');
-
-    // Execute Query
-    $result = $query->getResult();
-    $iterableResult = $query->toIterable();
-    $single = $query->getSingleResult();
-    $array = $query->getArrayResult();
-    $scalar = $query->getScalarResult();
-    $singleScalar = $query->getSingleScalarResult();
-
-The Expr class
-^^^^^^^^^^^^^^
-
-To workaround some of the issues that ``add()`` method may cause,
-Doctrine created a class that can be considered as a helper for
-building expressions. This class is called ``Expr``, which provides a
-set of useful methods to help build expressions:
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    // example8: QueryBuilder port of:
-    // "SELECT u FROM User u WHERE u.id = ? OR u.nickname LIKE ? ORDER BY u.name ASC" using Expr class
-    $qb->add('select', new Expr\Select(array('u')))
-       ->add('from', new Expr\From('User', 'u'))
-       ->add('where', $qb->expr()->orX(
-           $qb->expr()->eq('u.id', '?1'),
-           $qb->expr()->like('u.nickname', '?2')
-       ))
-       ->add('orderBy', new Expr\OrderBy('u.name', 'ASC'));
-
-Although it still sounds complex, the ability to programmatically
-create conditions are the main feature of ``Expr``. Here it is a
-complete list of supported helper methods available:
-
-.. code-block:: php
-
-    <?php
-    class Expr
-    {
-        /** Conditional objects **/
-
-        // Example - $qb->expr()->andX($cond1 [, $condN])->add(...)->...
-        public function andX($x = null); // Returns Expr\AndX instance
-
-        // Example - $qb->expr()->orX($cond1 [, $condN])->add(...)->...
-        public function orX($x = null); // Returns Expr\OrX instance
-
-
-        /** Comparison objects **/
-
-        // Example - $qb->expr()->eq('u.id', '?1') => u.id = ?1
-        public function eq($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->neq('u.id', '?1') => u.id <> ?1
-        public function neq($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->lt('u.id', '?1') => u.id < ?1
-        public function lt($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->lte('u.id', '?1') => u.id <= ?1
-        public function lte($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->gt('u.id', '?1') => u.id > ?1
-        public function gt($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->gte('u.id', '?1') => u.id >= ?1
-        public function gte($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->isNull('u.id') => u.id IS NULL
-        public function isNull($x); // Returns string
-
-        // Example - $qb->expr()->isNotNull('u.id') => u.id IS NOT NULL
-        public function isNotNull($x); // Returns string
-
-
-        /** Arithmetic objects **/
-
-        // Example - $qb->expr()->prod('u.id', '2') => u.id * 2
-        public function prod($x, $y); // Returns Expr\Math instance
-
-        // Example - $qb->expr()->diff('u.id', '2') => u.id - 2
-        public function diff($x, $y); // Returns Expr\Math instance
-
-        // Example - $qb->expr()->sum('u.id', '2') => u.id + 2
-        public function sum($x, $y); // Returns Expr\Math instance
-
-        // Example - $qb->expr()->quot('u.id', '2') => u.id / 2
-        public function quot($x, $y); // Returns Expr\Math instance
-
-
-        /** Pseudo-function objects **/
-
-        // Example - $qb->expr()->exists($qb2->getDql())
-        public function exists($subquery); // Returns Expr\Func instance
-
-        // Example - $qb->expr()->all($qb2->getDql())
-        public function all($subquery); // Returns Expr\Func instance
-
-        // Example - $qb->expr()->some($qb2->getDql())
-        public function some($subquery); // Returns Expr\Func instance
-
-        // Example - $qb->expr()->any($qb2->getDql())
-        public function any($subquery); // Returns Expr\Func instance
-
-        // Example - $qb->expr()->not($qb->expr()->eq('u.id', '?1'))
-        public function not($restriction); // Returns Expr\Func instance
-
-        // Example - $qb->expr()->in('u.id', array(1, 2, 3))
-        // Make sure that you do NOT use something similar to $qb->expr()->in('value', array('stringvalue')) as this will cause Doctrine to throw an Exception.
-        // Instead, use $qb->expr()->in('value', array('?1')) and bind your parameter to ?1 (see section above)
-        public function in($x, $y); // Returns Expr\Func instance
-
-        // Example - $qb->expr()->notIn('u.id', '2')
-        public function notIn($x, $y); // Returns Expr\Func instance
-
-        // Example - $qb->expr()->like('u.firstname', $qb->expr()->literal('Gui%'))
-        public function like($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->notLike('u.firstname', $qb->expr()->literal('Gui%'))
-        public function notLike($x, $y); // Returns Expr\Comparison instance
-
-        // Example - $qb->expr()->between('u.id', '1', '10')
-        public function between($val, $x, $y); // Returns Expr\Func
-
-
-        /** Function objects **/
-
-        // Example - $qb->expr()->trim('u.firstname')
-        public function trim($x); // Returns Expr\Func
-
-        // Example - $qb->expr()->concat('u.firstname', $qb->expr()->concat($qb->expr()->literal(' '), 'u.lastname'))
-        public function concat($x, $y); // Returns Expr\Func

-        // Example - $qb->expr()->substring('u.firstname', 0, 1)
-        public function substring($x, $from, $len); // Returns Expr\Func

-        // Example - $qb->expr()->upper('u.firstname')
-        public function upper($x); // Returns Expr\Func
-
-        // Example - $qb->expr()->length('u.firstname')
-        public function length($x); // Returns Expr\Func
-
-        // Example - $qb->expr()->avg('u.age')

-        // Example - $qb->expr()->count('u.firstname')
-        public function count($x); // Returns Expr\Func
-
-        // Example - $qb->expr()->countDistinct('u.surname')
-        public function countDistinct($x); // Returns Expr\Func
-    }
-
-Adding a Criteria to a Query
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You can also add a :ref:`filtering-collections` to a QueryBuilder by
-using ``addCriteria``:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\Common\Collections\Criteria;
-    // ...
-
-    $criteria = Criteria::create()
-        ->orderBy(['firstName', 'ASC']);
-
-    // $qb instanceof QueryBuilder
-    $qb->addCriteria($criteria);
-    // then execute your query like normal
-
-Low Level API
-^^^^^^^^^^^^^
-
-Now we will describe the low level method of creating queries.
-It may be useful to work at this level for optimization purposes,
-but most of the time it is preferred to work at a higher level of
-abstraction.
-
-All helper methods in ``QueryBuilder`` actually rely on a single
-one: ``add()``. This method is responsible of building every piece
-of DQL. It takes 3 parameters: ``$dqlPartName``, ``$dqlPart`` and
-``$append`` (default=false)
-
-
--  ``$dqlPartName``: Where the ``$dqlPart`` should be placed.
-   Possible values: select, from, where, groupBy, having, orderBy
--  ``$dqlPart``: What should be placed in ``$dqlPartName``. Accepts
-   a string or any instance of ``Doctrine\ORM\Query\Expr\*``
--  ``$append``: Optional flag (default=false) if the ``$dqlPart``
-   should override all previously defined items in ``$dqlPartName`` or
-   not (no effect on the ``where`` and ``having`` DQL query parts,
-   which always override all previously defined items)
-
--
-
-.. code-block:: php
-
-    <?php
-    // $qb instanceof QueryBuilder
-
-    // example6: how to define:
-    // "SELECT u FROM User u WHERE u.id = ? ORDER BY u.name ASC"
-    // using QueryBuilder string support
-    $qb->add('select', 'u')
-       ->add('from', 'User u')
-       ->add('where', 'u.id = ?1')
-       ->add('orderBy', 'u.name ASC');
-
-Expr\* classes
-^^^^^^^^^^^^^^
-
-When you call ``add()`` with string, it internally evaluates to an
-instance of ``Doctrine\ORM\Query\Expr\Expr\*`` class. Here is the
-same query of example 6 written using
-``Doctrine\ORM\Query\Expr\Expr\*`` classes:
-
-.. code-block:: php
-
-   <?php
-   // $qb instanceof QueryBuilder
-
-   // example7: how to define:
-   // "SELECT u FROM User u WHERE u.id = ? ORDER BY u.name ASC"
-   // using QueryBuilder using Expr\* instances
-   $qb->add('select', new Expr\Select(array('u')))
-      ->add('from', new Expr\From('User', 'u'))
-      ->add('where', new Expr\Comparison('u.id', '=', '?1'))
-      ->add('orderBy', new Expr\OrderBy('u.name', 'ASC'));

-The Second Level Cache
-======================
-
-.. note::
-
-    The second level cache functionality is marked as experimental for now. It
-    is a very complex feature and we cannot guarantee yet that it works stable
-    in all cases.
-
-The Second Level Cache is designed to reduce the amount of necessary database access.
-It sits between your application and the database to avoid the number of database hits as much as possible.
-
-When turned on, entities will be first searched in cache and if they are not found,
-a database query will be fired and then the entity result will be stored in a cache provider.
-
-There are some flavors of caching available, but is better to cache read-only data.
-
-Be aware that caches are not aware of changes made to the persistent store by another application.
-They can, however, be configured to regularly expire cached data.
-
-
-Caching Regions
----------------
-
-Second level cache does not store instances of an entity, instead it caches only entity identifier and values.
-Each entity class, collection association and query has its region, where values of each instance are stored.
-
-Caching Regions are specific region into the cache provider that might store entities, collection or queries.
-Each cache region resides in a specific cache namespace and has its own lifetime configuration.
-
-Notice that when caching collection and queries only identifiers are stored.
-The entity values will be stored in its own region
-
-Something like below for an entity region :
-
-.. code-block:: php
-
-    <?php
-    [
-      'region_name:entity_1_hash' => ['id'=> 1, 'name' => 'FooBar', 'associationName'=>null],
-      'region_name:entity_2_hash' => ['id'=> 2, 'name' => 'Foo', 'associationName'=>['id'=>11]],
-      'region_name:entity_3_hash' => ['id'=> 3, 'name' => 'Bar', 'associationName'=>['id'=>22]]
-    ];
-
-
-If the entity holds a collection that also needs to be cached.
-An collection region could look something like :
-
-.. code-block:: php
-
-    <?php
-    [
-      'region_name:entity_1_coll_assoc_name_hash' => ['ownerId'=> 1, 'list' => [1, 2, 3]],
-      'region_name:entity_2_coll_assoc_name_hash' => ['ownerId'=> 2, 'list' => [2, 3]],
-      'region_name:entity_3_coll_assoc_name_hash' => ['ownerId'=> 3, 'list' => [2, 4]]
-    ];
-
-A query region might be something like :
-
-.. code-block:: php
-
-    <?php
-    [
-      'region_name:query_1_hash' => ['list' => [1, 2, 3]],
-      'region_name:query_2_hash' => ['list' => [2, 3]],
-      'region_name:query_3_hash' => ['list' => [2, 4]]
-    ];
-
-
-.. note::
-
-    The following data structures represents now the cache will looks like, this is not actual cached data.

-
-Cache Regions
--------------
-
-``Doctrine\ORM\Cache\Region\DefaultRegion`` is the default implementation.
- A simplest cache region compatible with all doctrine-cache drivers but does not support locking.
-``Doctrine\ORM\Cache\Region`` and ``Doctrine\ORM\Cache\ConcurrentRegion``
-define contracts that should be implemented by a cache provider.
-
-It allows you to provide your own cache implementation that might take advantage of specific cache driver.
-
-If you want to support locking for ``READ_WRITE`` strategies you should implement ``ConcurrentRegion``; ``CacheRegion`` otherwise.
-
-
-Cache region
-~~~~~~~~~~~~
-
-``Doctrine\ORM\Cache\Region`` defines a contract for accessing a particular
-cache region.
-
-`See API Doc <https://www.doctrine-project.org/api/orm/current/Doctrine/ORM/Cache/Region.html>`_.
-
-Concurrent cache region
-~~~~~~~~~~~~~~~~~~~~~~~
-
-A ``Doctrine\ORM\Cache\ConcurrentRegion`` is designed to store concurrently managed data region.
-By default, Doctrine provides a very simple implementation based on file locks ``Doctrine\ORM\Cache\Region\FileLockRegion``.
-
-If you want to use an ``READ_WRITE`` cache, you should consider providing your own cache region.
-
-``Doctrine\ORM\Cache\ConcurrentRegion`` defines a contract for concurrently managed data region.
-
-`See API Doc <https://www.doctrine-project.org/api/orm/current/Doctrine/ORM/Cache/ConcurrentRegion.html>`_.
-
-Timestamp region
-~~~~~~~~~~~~~~~~
-
-``Doctrine\ORM\Cache\TimestampRegion``
-
-Tracks the timestamps of the most recent updates to particular entity.
-
-`See API Doc <http://www.doctrine-project.org/api/orm/current/Doctrine/ORM/Cache/TimestampRegion.html>`_.
-
-.. _reference-second-level-cache-mode:
-
-Caching mode
-------------
-
-* ``READ_ONLY`` (DEFAULT)
-
-  * Can do reads, inserts and deletes, cannot perform updates or employ any locks.
-  * Useful for data that is read frequently but never updated.
-  * Best performer.
-  * It is Simple.
-
-* ``NONSTRICT_READ_WRITE``
-
-  * Read Write Cache doesn’t employ any locks but can do reads, inserts, updates and deletes.
-  * Good if the application needs to update data rarely.
-    
-
-* ``READ_WRITE``
-
-  * Read Write cache employs locks before update/delete.
-  * Use if data needs to be updated.
-  * Slowest strategy.
-  * To use it a the cache region implementation must support locking.

-Configuration
--------------
-Doctrine allows you to specify configurations and some points of extension for the second-level-cache
-
-
-Enable Second Level Cache
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To enable the second-level-cache, you should provide a cache factory.
-``\Doctrine\ORM\Cache\DefaultCacheFactory`` is the default implementation.
-
-.. code-block:: php
-
-    <?php
-    /* @var $config \Doctrine\ORM\Cache\RegionsConfiguration */
-    /* @var $cache \Doctrine\Common\Cache\Cache */
-
-    $factory = new \Doctrine\ORM\Cache\DefaultCacheFactory($config, $cache);
-
-    // Enable second-level-cache
-    $config->setSecondLevelCacheEnabled();
-
-    // Cache factory
-    $config->getSecondLevelCacheConfiguration()
-        ->setCacheFactory($factory);
-
-
-Cache Factory
-~~~~~~~~~~~~~
-
-Cache Factory is the main point of extension.
-
-It allows you to provide a specific implementation of the following components :
-
-``QueryCache``
-    stores and retrieves query cache results.
-``CachedEntityPersister``
-    stores and retrieves entity results.
-``CachedCollectionPersister``
-    stores and retrieves query results.
-``EntityHydrator``
-    transforms entities into a cache entries and cache entries into entities
-``CollectionHydrator``
-    transforms collections into cache entries and cache entries into collections
-
-`See API Doc <http://www.doctrine-project.org/api/orm/current/Doctrine/ORM/Cache/DefaultCacheFactory.html>`_.
-
-Region Lifetime
-~~~~~~~~~~~~~~~
-
-To specify a default lifetime for all regions or specify a different lifetime for a specific region.
-
-.. code-block:: php
-
-    <?php
-    /* @var $config \Doctrine\ORM\Configuration */
-    /* @var $cacheConfig \Doctrine\ORM\Cache\CacheConfiguration */
-    $cacheConfig  =  $config->getSecondLevelCacheConfiguration();
-    $regionConfig =  $cacheConfig->getRegionsConfiguration();
-
-    // Cache Region lifetime
-    $regionConfig->setLifetime('my_entity_region', 3600);   // Time to live for a specific region (in seconds)
-    $regionConfig->setDefaultLifetime(7200);                // Default time to live (in seconds)
-
-
-Cache Log
-~~~~~~~~~
-By providing a cache logger you should be able to get information about all cache operations such as hits, misses and puts.
-
-``\Doctrine\ORM\Cache\Logging\StatisticsCacheLogger`` is a built-in implementation that provides basic statistics.
-
- .. code-block:: php
-
-    <?php
-    /* @var $config \Doctrine\ORM\Configuration */
-    $logger = new \Doctrine\ORM\Cache\Logging\StatisticsCacheLogger();
-
-    // Cache logger
-    $config->setSecondLevelCacheEnabled(true);
-    $config->getSecondLevelCacheConfiguration()
-        ->setCacheLogger($logger);
-
-
-    // Collect cache statistics
-
-    // Get the number of entries successfully retrieved from a specific region.
-    $logger->getRegionHitCount('my_entity_region');
-
-    // Get the number of cached entries *not* found in a specific region.
-    $logger->getRegionMissCount('my_entity_region');
-
-    // Get the number of cacheable entries put in cache.
-    $logger->getRegionPutCount('my_entity_region');
-
-    // Get the total number of put in all regions.
-    $logger->getPutCount();
-
-    // Get the total number of entries successfully retrieved from all regions.
-    $logger->getHitCount();
-
-    // Get the total number of cached entries *not* found in all regions.
-    $logger->getMissCount();
-
-If you want to get more information you should implement
-``\Doctrine\ORM\Cache\Logging\CacheLogger`` and collect
-all the information you want.
-
-`See API Doc <http://www.doctrine-project.org/api/orm/current/Doctrine/ORM/Cache/Logging/CacheLogger.html>`_.
-
-
-Entity cache definition
------------------------
-* Entity cache configuration allows you to define the caching strategy and region for an entity.
-
-  * ``usage`` specifies the caching strategy: ``READ_ONLY``,
-``NONSTRICT_READ_WRITE``, ``READ_WRITE``.
-See :ref:`reference-second-level-cache-mode`.
-  * ``region`` is an optional value that specifies the name of the second
-level cache region.
-
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        /**

-Association cache definition
-----------------------------
-The most common use case is to cache entities. But we can also cache relationships.
-It caches the primary keys of association and cache each element will be cached into its region.

-
-
-> Note: for this to work, the target entity must also be marked as cacheable.
-
-Cache usage
-~~~~~~~~~~~
-
-Basic entity cache
-
-.. code-block:: php
-
-    <?php
-    $em->persist(new Country($name));
-    $em->flush();                         // Hit database to insert the row and put into cache
-
-    $em->clear();                         // Clear entity manager
-
-    $country1  = $em->find('Country', 1); // Retrieve item from cache
-
-    $country->setName("New Name");
-    $em->persist($country);
-    $em->flush();                         // Hit database to update the row and update cache
-
-    $em->clear();                         // Clear entity manager
-
-    $country2  = $em->find('Country', 1); // Retrieve item from cache
-                                          // Notice that $country1 and $country2 are not the same instance.
-
-
-Association cache
-
-.. code-block:: php
-
-    <?php
-    // Hit database to insert the row and put into cache
-    $em->persist(new State($name, $country));
-    $em->flush();
-
-    // Clear entity manager
-    $em->clear();
-
-    // Retrieve item from cache
-    $state = $em->find('State', 1);
-
-    // Hit database to update the row and update cache entry
-    $state->setName("New Name");
-    $em->persist($state);
-    $em->flush();
-
-    // Create a new collection item
-    $city = new City($name, $state);
-    $state->addCity($city);
-
-    // Hit database to insert new collection item,
-    // put entity and collection cache into cache.
-    $em->persist($city);
-    $em->persist($state);
-    $em->flush();
-
-    // Clear entity manager
-    $em->clear();
-
-    // Retrieve item from cache
-    $state = $em->find('State', 1);
-
-    // Retrieve association from cache
-    $country = $state->getCountry();
-
-    // Retrieve collection from cache
-    $cities = $state->getCities();
-
-    echo $country->getName();
-    echo $state->getName();
-
-    // Retrieve each collection item from cache
-    foreach ($cities as $city) {
-        echo $city->getName();
-    }
-
-.. note::
-
-    Notice that all entities should be marked as cacheable.
-
-Using the query cache
----------------------
-
-The second level cache stores the entities, associations and collections.
-The query cache stores the results of the query but as identifiers, entity values are actually stored in the 2nd level cache.
-
-.. note::
-
-    Query cache should always be used in conjunction with the second-level-cache for those entities which should be cached.
-
-.. code-block:: php
-
-    <?php
-    /* @var $em \Doctrine\ORM\EntityManager */
-
-    // Execute database query, store query cache and entity cache
-    $result1 = $em->createQuery('SELECT c FROM Country c ORDER BY c.name')
-        ->setCacheable(true)
-        ->getResult();
-
-    $em->clear()
-
-    // Check if query result is valid and load entities from cache
-    $result2 = $em->createQuery('SELECT c FROM Country c ORDER BY c.name')
-        ->setCacheable(true)
-        ->getResult();
-
-Cache mode
-~~~~~~~~~~
-
-The Cache Mode controls how a particular query interacts with the second-level cache:
-
-* ``Cache::MODE_GET`` - May read items from the cache, but will not add items.
-* ``Cache::MODE_PUT`` - Will never read items from the cache, but will add items to the cache as it reads them from the database.
-* ``Cache::MODE_NORMAL`` - May read items from the cache, and add items to the cache.
-* ``Cache::MODE_REFRESH`` - The query will never read items from the cache, but will refresh items to the cache as it reads them from the database.
-
-.. code-block:: php
-
-    <?php
-    /* @var $em \Doctrine\ORM\EntityManager */
-    // Will refresh the query cache and all entities the cache as it reads from the database.
-    $result1 = $em->createQuery('SELECT c FROM Country c ORDER BY c.name')
-        ->setCacheMode(Cache::MODE_GET)
-        ->setCacheable(true)
-        ->getResult();
-
-.. note::
-
-    The the default query cache mode is ```Cache::MODE_NORMAL```
-
-DELETE / UPDATE queries
-~~~~~~~~~~~~~~~~~~~~~~~
-
-DQL UPDATE / DELETE statements are ported directly into a database and bypass
-the second-level cache.
-Entities that are already cached will NOT be invalidated.
-However the cached data could be evicted using the cache API or an special query hint.
-
-
-Execute the ``UPDATE`` and invalidate ``all cache entries`` using ``Query::HINT_CACHE_EVICT``
-
-.. code-block:: php
-
-    <?php
-    // Execute and invalidate
-    $this->_em->createQuery("UPDATE Entity\Country u SET u.name = 'unknown' WHERE u.id = 1")
-        ->setHint(Query::HINT_CACHE_EVICT, true)
-        ->execute();
-
-
-Execute the ``UPDATE`` and invalidate ``all cache entries`` using the cache API
-
-.. code-block:: php
-
-    <?php
-    // Execute
-    $this->_em->createQuery("UPDATE Entity\Country u SET u.name = 'unknown' WHERE u.id = 1")
-        ->execute();
-    // Invoke Cache API
-    $em->getCache()->evictEntityRegion('Entity\Country');
-
-
-Execute the ``UPDATE`` and invalidate ``a specific cache entry`` using the cache API
-
-.. code-block:: php
-
-    <?php
-    // Execute
-    $this->_em->createQuery("UPDATE Entity\Country u SET u.name = 'unknown' WHERE u.id = 1")
-        ->execute();
-    // Invoke Cache API
-    $em->getCache()->evictEntity('Entity\Country', 1);
-
-Using the repository query cache
---------------------------------
-
-As well as ``Query Cache`` all persister queries store only identifier values for an individual query.
-All persisters use a single timestamp cache region to keep track of the last update for each persister,
-When a query is loaded from cache, the timestamp region is checked for the last update for that persister.
-Using the last update timestamps as part of the query key invalidate the cache key when an update occurs.
-
-.. code-block:: php
-
-    <?php
-    // load from database and store cache query key hashing the query + parameters + last timestamp cache region..
-    $entities   = $em->getRepository('Entity\Country')->findAll();
-
-    // load from query and entities from cache..
-    $entities   = $em->getRepository('Entity\Country')->findAll();
-
-    // update the timestamp cache region for Country
-    $em->persist(new Country('zombieland'));
-    $em->flush();
-    $em->clear();
-
-    // Reload from database.
-    // At this point the query cache key is no longer valid, the select goes straight to the database
-    $entities   = $em->getRepository('Entity\Country')->findAll();
-
-Cache API
----------
-
-Caches are not aware of changes made by another application.
-However, you can use the cache API to check / invalidate cache entries.
-
-.. code-block:: php
-
-    <?php
-    /* @var $cache \Doctrine\ORM\Cache */
-    $cache = $em->getCache();
-
-    $cache->containsEntity('Entity\State', 1)      // Check if the cache exists
-    $cache->evictEntity('Entity\State', 1);        // Remove an entity from cache
-    $cache->evictEntityRegion('Entity\State');     // Remove all entities from cache
-
-    $cache->containsCollection('Entity\State', 'cities', 1);   // Check if the cache exists
-    $cache->evictCollection('Entity\State', 'cities', 1);      // Remove an entity collection from cache
-    $cache->evictCollectionRegion('Entity\State', 'cities');   // Remove all collections from cache
-
-Limitations
------------
-
-Composite primary key
-~~~~~~~~~~~~~~~~~~~~~
-
-Composite primary key are supported by second level cache,
-however when one of the keys is an association the cached entity should always be retrieved using the association identifier.
-For performance reasons the cache API does not extract from composite primary key.
-
-.. code-block:: php
-
-    <?php
-    /**
-     * @Entity
-     */
-    class Reference
-    {
-        /**
-         * @Id
-         * @ManyToOne(targetEntity="Article", inversedBy="references")
-         * @JoinColumn(name="source_id", referencedColumnName="article_id")
-         */
-        private $source;
-
-        /**
-         * @Id
-         * @ManyToOne(targetEntity="Article")
-         * @JoinColumn(name="target_id", referencedColumnName="article_id")
-         */
-        private $target;
-    }
-
-    // Supported
-    /* @var $article Article */
-    $article = $em->find('Article', 1);
-
-    // Supported
-    /* @var $article Article */
-    $article = $em->find('Article', $article);
-
-    // Supported
-    $id        = array('source' => 1, 'target' => 2);
-    $reference = $em->find('Reference', $id);
-
-    // NOT Supported
-    $id        = array('source' => new Article(1), 'target' => new Article(2));
-    $reference = $em->find('Reference', $id);
-
-Distributed environments
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Some cache driver are not meant to be used in a distributed environment.
-Load-balancer for distributing workloads across multiple computing resources
-should be used in conjunction with distributed caching system such as memcached, redis, riak ...
-
-Caches should be used with care when using a load-balancer if you don't share the cache.
-While using APC or any file based cache update occurred in a specific machine would not reflect to the cache in other machines.
-
-
-Paginator
-~~~~~~~~~
-
-Count queries generated by ``Doctrine\ORM\Tools\Pagination\Paginator`` are not cached by second-level cache.
-Although entities and query result are cached, count queries will hit the

-Security
-========
-
-The Doctrine library is operating very close to your database and as such needs
-to handle and make assumptions about SQL injection vulnerabilities.
-
-It is vital that you understand how Doctrine approaches security, because
-we cannot protect you from SQL injection.
-
-Please also read the documentation chapter on Security in Doctrine DBAL. This
-page only handles Security issues in the ORM.
-
-- `DBAL Security Page <http://www.doctrine-project.org/projects/doctrine-dbal/en/current/reference/security.html>`
-
-If you find a Security bug in Doctrine, please report it on Jira and change the
-Security Level to "Security Issues". It will be visible to Doctrine Core
-developers and you only.
-
-User input and Doctrine ORM
----------------------------
-
-The ORM is much better at protecting against SQL injection than the DBAL alone.
-You can consider the following APIs to be safe from SQL injection:
-
-- ``\Doctrine\ORM\EntityManager#find()`` and ``getReference()``.
-- All values on Objects inserted and updated through ``Doctrine\ORM\EntityManager#persist()``
-- All find methods on ``Doctrine\ORM\EntityRepository``.
-- User Input set to DQL Queries or QueryBuilder methods through
-    - ``setParameter()`` or variants
-    - ``setMaxResults()``
-    - ``setFirstResult()``
-- Queries through the Criteria API on ``Doctrine\ORM\PersistentCollection`` and
-  ``Doctrine\ORM\EntityRepository``.
-
-You are **NOT** safe from SQL injection when using user input with:
-
-- Expression API of ``Doctrine\ORM\QueryBuilder``
-- Concatenating user input into DQL SELECT, UPDATE or DELETE statements or
-  Native SQL.
-
-This means SQL injections can only occur with Doctrine ORM when working with
-Query Objects of any kind. The safe rule is to always use prepared statement
-parameters for user objects when using a Query object.
-
-.. warning::
-
-    Insecure code follows, don't copy paste this.
-
-The following example shows insecure DQL usage:
-
-.. code-block:: php
-
-    <?php
-
-    // INSECURE
-    $dql = "SELECT u
-              FROM MyProject\Entity\User u
-             WHERE u.status = '" .  $_GET['status'] . "'
-         ORDER BY " . $_GET['orderField'] . " ASC";
-
-For Doctrine there is absolutely no way to find out which parts of ``$dql`` are
-from user input and which are not, even if we have our own parsing process
-this is technically impossible. The correct way is:
-
-.. code-block:: php
-
-    <?php
-
-    $orderFieldWhitelist = array('email', 'username');
-    $orderField = "email";
-
-    if (in_array($_GET['orderField'], $orderFieldWhitelist)) {
-        $orderField = $_GET['orderField'];
-    }
-
-    $dql = "SELECT u
-              FROM MyProject\Entity\User u
-             WHERE u.status = ?1
-         ORDER BY u." . $orderField . " ASC";
-
-    $query = $entityManager->createQuery($dql);
-    $query->setParameter(1, $_GET['status']);
-
-
-Preventing Mass Assignment Vulnerabilities
-------------------------------------------
-
-ORMs are very convenient for CRUD applications and Doctrine is no exception.
-However CRUD apps are often vulnerable to mass assignment security problems
-when implemented naively.
-
-Doctrine is not vulnerable to this problem out of the box, but you can easily
-make your entities vulnerable to mass assignment when you add methods of
-the kind ``updateFromArray()`` or ``updateFromJson()`` to them. A vulnerable
-entity might look like this:
-
-.. code-block:: php
-
-    <?php
-
-    /**
-     * @Entity
-     */
-    class InsecureEntity
-    {
-        /** @Id @Column(type="integer") @GeneratedValue */
-        private $id;
-        /** @Column */
-        private $email;
-        /** @Column(type="boolean") */
-        private $isAdmin;
-
-        public function fromArray(array $userInput)
-        {
-            foreach ($userInput as $key => $value) {
-                $this->$key = $value;
-            }
-        }
-    }
-
-Now the possiblity of mass-asignment exists on this entity and can
-be exploited by attackers to set the "isAdmin" flag to true on any
-object when you pass the whole request data to this method like:
-
-.. code-block:: php
-
-    <?php
-    $entity = new InsecureEntity();
-    $entity->fromArray($_POST);
-
-    $entityManager->persist($entity);
-    $entityManager->flush();
-
-You can spot this problem in this very simple example easily. However
-in combination with frameworks and form libraries it might not be
-so obvious when this issue arises. Be careful to avoid this
-kind of mistake.
-
-How to fix this problem? You should always have a whitelist
-of allowed key to set via mass assignment functions.
-
-.. code-block:: php
-
-    public function fromArray(array $userInput, $allowedFields = array())
-    {
-        foreach ($userInput as $key => $value) {
-            if (in_array($key, $allowedFields)) {
-                $this->$key = $value;
-            }
-        }
-    }

-Tools
-=====
-
-Doctrine Console
-----------------
-
-The Doctrine Console is a Command Line Interface tool for simplifying common
-administration tasks during the development of a project that uses ORM.
-
-Take a look at the :doc:`Installation and Configuration <configuration>`
-chapter for more information how to setup the console command.
-
-Display Help Information
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Type ``php vendor/bin/doctrine`` on the command line and you should see an
-overview of the available commands or use the --help flag to get
-information on the available commands. If you want to know more
-about the use of generate entities for example, you can call:
-
-.. code-block:: php
-
-    $> php vendor/bin/doctrine orm:generate-entities --help
-
-
-Configuration
-~~~~~~~~~~~~~
-
-Whenever the ``doctrine`` command line tool is invoked, it can
-access all Commands that were registered by a developer. There is no
-auto-detection mechanism at work. The Doctrine binary
-already registers all the commands that currently ship with
-Doctrine DBAL and ORM. If you want to use additional commands you
-have to register them yourself.
-
-All the commands of the Doctrine Console require access to the
-``EntityManager``. You have to inject it into the console application with
-``ConsoleRunner::createHelperSet``. Whenever you invoke the Doctrine
-binary, it searches the current directory for the file ``cli-config.php``.
-This file contains the project-specific configuration.
-
-Here is an example of a the project-specific ``cli-config.php``:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Tools\Console\ConsoleRunner;
-
-    // replace this with the path to your own project bootstrap file.
-    require_once 'bootstrap.php';
-
-    // replace with mechanism to retrieve EntityManager in your app
-    $entityManager = GetEntityManager();
-
-    return ConsoleRunner::createHelperSet($entityManager);
-
-.. note::
-
-    You have to adjust this snippet for your specific application or framework
-    and use their facilities to access the Doctrine EntityManager and
-    Connection Resources.
-
-Command Overview
-~~~~~~~~~~~~~~~~
-
-The following Commands are currently available:
-
-
--  ``help`` Displays help for a command (?)
--  ``list`` Lists commands
--  ``dbal:import`` Import SQL file(s) directly to Database.
--  ``dbal:run-sql`` Executes arbitrary SQL directly from the
-   command line.
--  ``orm:clear-cache:metadata`` Clear all metadata cache of the
-   various cache drivers.
--  ``orm:clear-cache:query`` Clear all query cache of the various
-   cache drivers.
--  ``orm:clear-cache:result`` Clear result cache of the various
-   cache drivers.
--  ``orm:convert-d1-schema`` Converts Doctrine 1.X schema into a
-   Doctrine 2.X schema.
--  ``orm:convert-mapping`` Convert mapping information between
-   supported formats.
--  ``orm:ensure-production-settings`` Verify that Doctrine is
-   properly configured for a production environment.
--  ``orm:generate-entities`` Generate entity classes and method
-   stubs from your mapping information.
--  ``orm:generate-proxies`` Generates proxy classes for entity
-   classes.
--  ``orm:generate-repositories`` Generate repository classes from
-   your mapping information.
--  ``orm:run-dql`` Executes arbitrary DQL directly from the command
-   line.
--  ``orm:schema-tool:create`` Processes the schema and either
-   create it directly on EntityManager Storage Connection or generate
-   the SQL output.
--  ``orm:schema-tool:drop`` Processes the schema and either drop
-   the database schema of EntityManager Storage Connection or generate
-   the SQL output.
--  ``orm:schema-tool:update`` Processes the schema and either
-   update the database schema of EntityManager Storage Connection or
-   generate the SQL output.
-
-For these commands are also available aliases:
-
-
--  ``orm:convert:d1-schema`` is alias for ``orm:convert-d1-schema``.
--  ``orm:convert:mapping`` is alias for ``orm:convert-mapping``.
--  ``orm:generate:entities`` is alias for ``orm:generate-entities``.
--  ``orm:generate:proxies`` is alias for ``orm:generate-proxies``.
--  ``orm:generate:repositories`` is alias for ``orm:generate-repositories``.
-
-.. note::
-
-    Console also supports auto completion, for example, instead of
-    ``orm:clear-cache:query`` you can use just ``o:c:q``.
-
-Database Schema Generation
---------------------------
-
-.. note::
-
-    SchemaTool can do harm to your database. It will drop or alter
-    tables, indexes, sequences and such. Please use this tool with
-    caution in development and not on a production server. It is meant
-    for helping you develop your Database Schema, but NOT with
-    migrating schema from A to B in production. A safe approach would
-    be generating the SQL on development server and saving it into SQL
-    Migration files that are executed manually on the production
-    server.
-
-    SchemaTool assumes your Doctrine Project uses the given database on
-    its own. Update and Drop commands will mess with other tables if
-    they are not related to the current project that is using Doctrine.
-    Please be careful!
-
-
-To generate your database schema from your Doctrine mapping files
-you can use the ``SchemaTool`` class or the ``schema-tool`` Console
-Command.
-
-When using the SchemaTool class directly, create your schema using
-the ``createSchema()`` method. First create an instance of the
-``SchemaTool`` and pass it an instance of the ``EntityManager``
-that you want to use to create the schema. This method receives an
-array of ``ClassMetadataInfo`` instances.
-
-.. code-block:: php
-
-    <?php
-    $tool = new \Doctrine\ORM\Tools\SchemaTool($em);
-    $classes = array(
-      $em->getClassMetadata('Entities\User'),
-      $em->getClassMetadata('Entities\Profile')
-    );
-    $tool->createSchema($classes);
-
-To drop the schema you can use the ``dropSchema()`` method.
-
-.. code-block:: php
-
-    <?php
-    $tool->dropSchema($classes);
-
-This drops all the tables that are currently used by your metadata
-model. When you are changing your metadata a lot during development
-you might want to drop the complete database instead of only the
-tables of the current model to clean up with orphaned tables.
-
-.. code-block:: php
-
-    <?php
-    $tool->dropSchema($classes, \Doctrine\ORM\Tools\SchemaTool::DROP_DATABASE);
-
-You can also use database introspection to update your schema
-easily with the ``updateSchema()`` method. It will compare your
-existing database schema to the passed array of
-``ClassMetadataInfo`` instances.
-
-.. code-block:: php
-
-    <?php
-    $tool->updateSchema($classes);
-
-If you want to use this functionality from the command line you can
-use the ``schema-tool`` command.
-
-To create the schema use the ``create`` command:
-
-.. code-block:: php
-
-    $ php doctrine orm:schema-tool:create
-
-To drop the schema use the ``drop`` command:
-
-.. code-block:: php
-
-    $ php doctrine orm:schema-tool:drop
-
-If you want to drop and then recreate the schema then use both
-options:
-
-.. code-block:: php
-
-    $ php doctrine orm:schema-tool:drop
-    $ php doctrine orm:schema-tool:create
-
-As you would think, if you want to update your schema use the
-``update`` command:
-
-.. code-block:: php
-
-    $ php doctrine orm:schema-tool:update
-
-All of the above commands also accept a ``--dump-sql`` option that
-will output the SQL for the ran operation.
-
-.. code-block:: php
-
-    $ php doctrine orm:schema-tool:create --dump-sql
-
-Before using the orm:schema-tool commands, remember to configure
-your cli-config.php properly.
-
-Entity Generation
------------------
-
-Generate entity classes and method stubs from your mapping information.
-
-.. code-block:: php
-
-    $ php doctrine orm:generate-entities
-    $ php doctrine orm:generate-entities --update-entities
-    $ php doctrine orm:generate-entities --regenerate-entities
-
-This command is not suited for constant usage. It is a little helper and does
-not support all the mapping edge cases very well. You still have to put work
-in your entities after using this command.
-
-It is possible to use the EntityGenerator on code that you have already written. It will
-not be lost. The EntityGenerator will only append new code to your
-file and will not delete the old code. However this approach may still be prone
-to error and we suggest you use code repositories such as GIT or SVN to make
-backups of your code.
-
-It makes sense to generate the entity code if you are using entities as Data
-Access Objects only and don't put much additional logic on them. If you are
-however putting much more logic on the entities you should refrain from using
-the entity-generator and code your entities manually.
-
-.. note::
-
-    Even if you specified Inheritance options in your
-    XML or YAML Mapping files the generator cannot generate the base and
-    child classes for you correctly, because it doesn't know which
-    class is supposed to extend which. You have to adjust the entity
-    code manually for inheritance to work!
-
-
-Convert Mapping Information
----------------------------
-
-Convert mapping information between supported formats.
-
-This is an **execute one-time** command. It should not be necessary for
-you to call this method multiple times, especially when using the ``--from-database``
-flag.
-
-Converting an existing database schema into mapping files only solves about 70-80%
-of the necessary mapping information. Additionally the detection from an existing
-database cannot detect inverse associations, inheritance types,
-entities with foreign keys as primary keys and many of the
-semantical operations on associations such as cascade.
-
-.. note::
-
-    There is no need to convert YAML or XML mapping files to annotations
-    every time you make changes. All mapping drivers are first class citizens
-    in Doctrine 2 and can be used as runtime mapping for the ORM. See the
-    docs on XML and YAML Mapping for an example how to register this metadata
-    drivers as primary mapping source.
-
-To convert some mapping information between the various supported
-formats you can use the ``ClassMetadataExporter`` to get exporter
-instances for the different formats:
-
-.. code-block:: php
-
-    <?php
-    $cme = new \Doctrine\ORM\Tools\Export\ClassMetadataExporter();
-
-Once you have a instance you can use it to get an exporter. For
-example, the yml exporter:
-
-.. code-block:: php
-
-    <?php
-    $exporter = $cme->getExporter('yml', '/path/to/export/yml');
-
-Now you can export some ``ClassMetadata`` instances:
-
-.. code-block:: php
-
-    <?php
-    $classes = array(
-      $em->getClassMetadata('Entities\User'),
-      $em->getClassMetadata('Entities\Profile')
-    );
-    $exporter->setMetadata($classes);
-    $exporter->export();
-
-This functionality is also available from the command line to
-convert your loaded mapping information to another format. The
-``orm:convert-mapping`` command accepts two arguments, the type to
-convert to and the path to generate it:
-
-.. code-block:: php
-
-    $ php doctrine orm:convert-mapping xml /path/to/mapping-path-converted-to-xml
-
-Reverse Engineering
--------------------
-
-You can use the ``DatabaseDriver`` to reverse engineer a database
-to an array of ``ClassMetadataInfo`` instances and generate YAML,
-XML, etc. from them.
-
-.. note::
-
-    Reverse Engineering is a **one-time** process that can get you started with a project.
-    Converting an existing database schema into mapping files only detects about 70-80%
-    of the necessary mapping information. Additionally the detection from an existing
-    database cannot detect inverse associations, inheritance types,
-    entities with foreign keys as primary keys and many of the
-    semantical operations on associations such as cascade.
-
-First you need to retrieve the metadata instances with the
-``DatabaseDriver``:
-
-.. code-block:: php
-
-    <?php
-    $em->getConfiguration()->setMetadataDriverImpl(
-        new \Doctrine\ORM\Mapping\Driver\DatabaseDriver(
-            $em->getConnection()->getSchemaManager()
-        )
-    );
-
-    $cmf = new \Doctrine\ORM\Tools\DisconnectedClassMetadataFactory();
-    $cmf->setEntityManager($em);
-    $metadata = $cmf->getAllMetadata();
-
-Now you can get an exporter instance and export the loaded metadata
-to yml:
-
-.. code-block:: php
-
-    <?php
-    $cme = new \Doctrine\ORM\Tools\Export\ClassMetadataExporter();
-    $exporter = $cme->getExporter('yml', '/path/to/export/yml');
-    $exporter->setMetadata($metadata);
-    $exporter->export();
-
-You can also reverse engineer a database using the
-``orm:convert-mapping`` command:
-
-.. code-block:: php
-
-    $ php doctrine orm:convert-mapping --from-database yml /path/to/mapping-path-converted-to-yml
-
-.. note::
-
-    Reverse Engineering is not always working perfectly
-    depending on special cases. It will only detect Many-To-One
-    relations (even if they are One-To-One) and will try to create
-    entities from Many-To-Many tables. It also has problems with naming
-    of foreign keys that have multiple column names. Any Reverse
-    Engineered Database-Schema needs considerable manual work to become
-    a useful domain model.
-
-
-Runtime vs Development Mapping Validation
------------------------------------------
-
-For performance reasons Doctrine ORM has to skip some of the
-necessary validation of metadata mappings. You have to execute
-this validation in your development workflow to verify the
-associations are correctly defined.
-
-You can either use the Doctrine Command Line Tool:
-
-.. code-block:: php
-
-    doctrine orm:validate-schema
-
-Or you can trigger the validation manually:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Tools\SchemaValidator;
-
-    $validator = new SchemaValidator($entityManager);
-    $errors = $validator->validateMapping();
-
-    if (count($errors) > 0) {
-        // Lots of errors!
-        echo implode("\n\n", $errors);
-    }
-
-If the mapping is invalid the errors array contains a positive
-number of elements with error messages.
-
-.. warning::
-
-    One mapping option that is not validated is the use of the referenced column name.
-    It has to point to the equivalent primary key otherwise Doctrine will not work.
-
-.. note::
-
-    One common error is to use a backlash in front of the
-    fully-qualified class-name. Whenever a FQCN is represented inside a
-    string (such as in your mapping definitions) you have to drop the
-    prefix backslash. PHP does this with ``get_class()`` or Reflection
-    methods for backwards compatibility reasons.
-
-
-Adding own commands
--------------------
-
-You can also add your own commands on-top of the Doctrine supported
-tools if you are using a manually built console script.
-
-To include a new command on Doctrine Console, you need to do modify the
-``doctrine.php`` file a little:
-
-.. code-block:: php
-
-    <?php
-    // doctrine.php
-    use Symfony\Component\Console\Application;
-
-    // as before ...
-
-    // replace the ConsoleRunner::run() statement with:
-    $cli = new Application('Doctrine Command Line Interface', \Doctrine\ORM\Version::VERSION);
-    $cli->setCatchExceptions(true);
-    $cli->setHelperSet($helperSet);
-
-    // Register All Doctrine Commands
-    ConsoleRunner::addCommands($cli);
-
-    // Register your own command
-    $cli->addCommand(new \MyProject\Tools\Console\Commands\MyCustomCommand);
-
-    // Runs console application
-    $cli->run();
-
-Additionally, include multiple commands (and overriding previously
-defined ones) is possible through the command:
-
-.. code-block:: php
-
-    <?php
-
-    $cli->addCommands(array(
-        new \MyProject\Tools\Console\Commands\MyCustomCommand(),
-        new \MyProject\Tools\Console\Commands\SomethingCommand(),
-        new \MyProject\Tools\Console\Commands\AnotherCommand(),
-        new \MyProject\Tools\Console\Commands\OneMoreCommand(),
-    ));
-
-
-Re-use console application
---------------------------
-
-You are also able to retrieve and re-use the default console application.
-Just call ``ConsoleRunner::createApplication(...)`` with an appropriate
-HelperSet, like it is described in the configuration section.
-
-.. code-block:: php
-
-    <?php
-
-    // Retrieve default console application
-    $cli = ConsoleRunner::createApplication($helperSet);
-
-    // Runs console application
-    $cli->run();

-Transactions and Concurrency
-============================
-
-.. _transactions-and-concurrency_transaction-demarcation:
-
-Transaction Demarcation
------------------------
-
-Transaction demarcation is the task of defining your transaction
-boundaries. Proper transaction demarcation is very important
-because if not done properly it can negatively affect the
-performance of your application. Many databases and database
-abstraction layers like PDO by default operate in auto-commit mode,
-which means that every single SQL statement is wrapped in a small
-transaction. Without any explicit transaction demarcation from your
-side, this quickly results in poor performance because transactions
-are not cheap.
-
-For the most part, Doctrine ORM already takes care of proper
-transaction demarcation for you: All the write operations
-(INSERT/UPDATE/DELETE) are queued until ``EntityManager#flush()``
-is invoked which wraps all of these changes in a single
-transaction.
-
-However, Doctrine ORM also allows (and encourages) you to take over
-and control transaction demarcation yourself.
-
-These are two ways to deal with transactions when using the
-Doctrine ORM and are now described in more detail.
-
-.. _transactions-and-concurrency_approach-implicitly:
-
-Approach 1: Implicitly
-~~~~~~~~~~~~~~~~~~~~~~
-
-The first approach is to use the implicit transaction handling
-provided by the Doctrine ORM EntityManager. Given the following
-code snippet, without any explicit transaction demarcation:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-    $user = new User;
-    $user->setName('George');
-    $em->persist($user);
-    $em->flush();
-
-Since we do not do any custom transaction demarcation in the above
-code, ``EntityManager#flush()`` will begin and commit/rollback a
-transaction. This behavior is made possible by the aggregation of
-the DML operations by the Doctrine ORM and is sufficient if all the
-data manipulation that is part of a unit of work happens through
-the domain model and thus the ORM.
-
-.. _transactions-and-concurrency_approach-explicitly:
-
-Approach 2: Explicitly
-~~~~~~~~~~~~~~~~~~~~~~
-
-The explicit alternative is to use the ``Doctrine\DBAL\Connection``
-API directly to control the transaction boundaries. The code then
-looks like this:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-    $em->getConnection()->beginTransaction(); // suspend auto-commit
-    try {
-        //... do some work
-        $user = new User;
-        $user->setName('George');
-        $em->persist($user);
-        $em->flush();
-        $em->getConnection()->commit();
-    } catch (Exception $e) {
-        $em->getConnection()->rollBack();
-        throw $e;
-    }
-
-Explicit transaction demarcation is required when you want to
-include custom DBAL operations in a unit of work or when you want
-to make use of some methods of the ``EntityManager`` API that
-require an active transaction. Such methods will throw a
-``TransactionRequiredException`` to inform you of that
-requirement.
-
-A more convenient alternative for explicit transaction demarcation is the use
-of provided control abstractions in the form of
-``Connection#transactional($func)`` and ``EntityManager#transactional($func)``.
-When used, these control abstractions ensure that you never forget to rollback
-the transaction, in addition to the obvious code reduction. An example that is
-functionally equivalent to the previously shown code looks as follows:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-    $em->transactional(function($em) {
-        //... do some work
-        $user = new User;
-        $user->setName('George');
-        $em->persist($user);
-    });
-
-.. warning::
-
-    For historical reasons, ``EntityManager#transactional($func)`` will return
-    ``true`` whenever the return value of ``$func`` is loosely false.
-    Some examples of this include ``array()``, ``"0"``, ``""``, ``0``, and
-    ``null``.
-
-The difference between ``Connection#transactional($func)`` and
-``EntityManager#transactional($func)`` is that the latter
-abstraction flushes the ``EntityManager`` prior to transaction
-commit and rolls back the transaction when an
-exception occurs.
-
-.. _transactions-and-concurrency_exception-handling:
-
-Exception Handling
-~~~~~~~~~~~~~~~~~~
-
-When using implicit transaction demarcation and an exception occurs
-during ``EntityManager#flush()``, the transaction is automatically
-rolled back and the ``EntityManager`` closed.
-
-When using explicit transaction demarcation and an exception
-occurs, the transaction should be rolled back immediately and the
-``EntityManager`` closed by invoking ``EntityManager#close()`` and
-subsequently discarded, as demonstrated in the example above. This
-can be handled elegantly by the control abstractions shown earlier.
-Note that when catching ``Exception`` you should generally re-throw
-the exception. If you intend to recover from some exceptions, catch
-them explicitly in earlier catch blocks (but do not forget to
-rollback the transaction and close the ``EntityManager`` there as
-well). All other best practices of exception handling apply
-similarly (i.e. either log or re-throw, not both, etc.).
-
-As a result of this procedure, all previously managed or removed
-instances of the ``EntityManager`` become detached. The state of
-the detached objects will be the state at the point at which the
-transaction was rolled back. The state of the objects is in no way
-rolled back and thus the objects are now out of synch with the
-database. The application can continue to use the detached objects,
-knowing that their state is potentially no longer accurate.
-
-If you intend to start another unit of work after an exception has
-occurred you should do that with a new ``EntityManager``.
-

-
-Locking Support
----------------
-
-Doctrine ORM offers support for Pessimistic- and Optimistic-locking
-strategies natively. This allows to take very fine-grained control
-over what kind of locking is required for your Entities in your
-application.
-
-.. _transactions-and-concurrency_optimistic-locking:
-
-Optimistic Locking
-~~~~~~~~~~~~~~~~~~
-
-Database transactions are fine for concurrency control during a
-single request. However, a database transaction should not span
-across requests, the so-called "user think time". Therefore a
-long-running "business transaction" that spans multiple requests
-needs to involve several database transactions. Thus, database
-transactions alone can no longer control concurrency during such a
-long-running business transaction. Concurrency control becomes the
-partial responsibility of the application itself.
-
-Doctrine has integrated support for automatic optimistic locking
-via a version field. In this approach any entity that should be
-protected against concurrent modifications during long-running
-business transactions gets a version field that is either a simple
-number (mapping type: integer) or a timestamp (mapping type:
-datetime). When changes to such an entity are persisted at the end
-of a long-running conversation the version of the entity is
-compared to the version in the database and if they don't match, an
-``OptimisticLockException`` is thrown, indicating that the entity
-has been modified by someone else already.
-
-You designate a version field in an entity as follows. In this
-example we'll use an integer.
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        class User
-        {
-            // ...
-            /** @Version @Column(type="integer") */
-            private $version;
-            // ...
-        }
-
-    .. code-block:: xml
-
-        <doctrine-mapping>
-          <entity name="User">
-            <field name="version" type="integer" version="true" />
-          </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        User:
-          type: entity
-          fields:
-            version:
-              type: integer
-              version: true
-
-Alternatively a datetime type can be used (which maps to a SQL
-timestamp or datetime):
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        class User
-        {
-            // ...
-            /** @Version @Column(type="datetime") */
-            private $version;
-            // ...
-        }
-
-    .. code-block:: xml
-
-        <doctrine-mapping>
-          <entity name="User">
-            <field name="version" type="datetime" version="true" />
-          </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        User:
-          type: entity
-          fields:
-            version:
-              type: datetime
-              version: true
-
-Version numbers (not timestamps) should however be preferred as
-they can not potentially conflict in a highly concurrent
-environment, unlike timestamps where this is a possibility,
-depending on the resolution of the timestamp on the particular
-database platform.
-
-When a version conflict is encountered during
-``EntityManager#flush()``, an ``OptimisticLockException`` is thrown
-and the active transaction rolled back (or marked for rollback).
-This exception can be caught and handled. Potential responses to an
-OptimisticLockException are to present the conflict to the user or
-to refresh or reload objects in a new transaction and then retrying
-the transaction.
-
-With PHP promoting a share-nothing architecture, the time between
-showing an update form and actually modifying the entity can in the
-worst scenario be as long as your applications session timeout. If
-changes happen to the entity in that time frame you want to know
-directly when retrieving the entity that you will hit an optimistic
-locking exception:
-
-You can always verify the version of an entity during a request
-either when calling ``EntityManager#find()``:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\DBAL\LockMode;
-    use Doctrine\ORM\OptimisticLockException;
-    
-    $theEntityId = 1;
-    $expectedVersion = 184;
-    
-    try {
-        $entity = $em->find('User', $theEntityId, LockMode::OPTIMISTIC, $expectedVersion);
-    
-        // do the work
-    
-        $em->flush();
-    } catch(OptimisticLockException $e) {
-        echo "Sorry, but someone else has already changed this entity. Please apply the changes again!";
-    }
-
-Or you can use ``EntityManager#lock()`` to find out:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\DBAL\LockMode;
-    use Doctrine\ORM\OptimisticLockException;
-    
-    $theEntityId = 1;
-    $expectedVersion = 184;
-    
-    $entity = $em->find('User', $theEntityId);
-    
-    try {
-        // assert version
-        $em->lock($entity, LockMode::OPTIMISTIC, $expectedVersion);
-    
-    } catch(OptimisticLockException $e) {
-        echo "Sorry, but someone else has already changed this entity. Please apply the changes again!";
-    }
-
-Important Implementation Notes
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-You can easily get the optimistic locking workflow wrong if you
-compare the wrong versions. Say you have Alice and Bob editing a
-hypothetical blog post:
-
--  Alice reads the headline of the blog post being "Foo", at
-   optimistic lock version 1 (GET Request)
--  Bob reads the headline of the blog post being "Foo", at
-   optimistic lock version 1 (GET Request)
--  Bob updates the headline to "Bar", upgrading the optimistic lock
-   version to 2 (POST Request of a Form)
--  Alice updates the headline to "Baz", ... (POST Request of a
-   Form)
-
-Now at the last stage of this scenario the blog post has to be read
-again from the database before Alice's headline can be applied. At
-this point you will want to check if the blog post is still at
-version 1 (which it is not in this scenario).
-
-Using optimistic locking correctly, you *have* to add the version
-as an additional hidden field (or into the SESSION for more
-safety). Otherwise you cannot verify the version is still the one
-being originally read from the database when Alice performed her
-GET request for the blog post. If this happens you might see lost
-updates you wanted to prevent with Optimistic Locking.
-
-See the example code, The form (GET Request):
-
-.. code-block:: php
-
-    <?php
-    $post = $em->find('BlogPost', 123456);
-    
-    echo '<input type="hidden" name="id" value="' . $post->getId() . '" />';
-    echo '<input type="hidden" name="version" value="' . $post->getCurrentVersion() . '" />';
-
-And the change headline action (POST Request):
-
-.. code-block:: php
-
-    <?php
-    $postId = (int)$_GET['id'];
-    $postVersion = (int)$_GET['version'];
-    
-    $post = $em->find('BlogPost', $postId, \Doctrine\DBAL\LockMode::OPTIMISTIC, $postVersion);
-
-.. _transactions-and-concurrency_pessimistic-locking:
-
-Pessimistic Locking
-~~~~~~~~~~~~~~~~~~~
-
-Doctrine ORM supports Pessimistic Locking at the database level. No
-attempt is being made to implement pessimistic locking inside
-Doctrine, rather vendor-specific and ANSI-SQL commands are used to
-acquire row-level locks. Every Entity can be part of a pessimistic
-lock, there is no special metadata required to use this feature.
-
-However for Pessimistic Locking to work you have to disable the
-Auto-Commit Mode of your Database and start a transaction around
-your pessimistic lock use-case using the "Approach 2: Explicit
-Transaction Demarcation" described above. Doctrine ORM will throw an
-Exception if you attempt to acquire an pessimistic lock and no
-transaction is running.
-
-Doctrine ORM currently supports two pessimistic lock modes:
-
-
--  Pessimistic Write
-   (``Doctrine\DBAL\LockMode::PESSIMISTIC_WRITE``), locks the
-   underlying database rows for concurrent Read and Write Operations.
--  Pessimistic Read (``Doctrine\DBAL\LockMode::PESSIMISTIC_READ``),
-   locks other concurrent requests that attempt to update or lock rows
-   in write mode.
-
-You can use pessimistic locks in three different scenarios:
-
-
-1. Using
-   ``EntityManager#find($className, $id, \Doctrine\DBAL\LockMode::PESSIMISTIC_WRITE)``
-   or
-   ``EntityManager#find($className, $id, \Doctrine\DBAL\LockMode::PESSIMISTIC_READ)``
-2. Using
-   ``EntityManager#lock($entity, \Doctrine\DBAL\LockMode::PESSIMISTIC_WRITE)``
-   or
-   ``EntityManager#lock($entity, \Doctrine\DBAL\LockMode::PESSIMISTIC_READ)``
-3. Using
-   ``Query#setLockMode(\Doctrine\DBAL\LockMode::PESSIMISTIC_WRITE)``
-   or
-   ``Query#setLockMode(\Doctrine\DBAL\LockMode::PESSIMISTIC_READ)``

-Association Updates: Owning Side and Inverse Side
-=================================================
-
-When mapping bidirectional associations it is important to
-understand the concept of the owning and inverse sides. The
-following general rules apply:
-
--  Relationships may be bidirectional or unidirectional.
--  A bidirectional relationship has both an owning side and an inverse side
--  A unidirectional relationship only has an owning side.
--  Doctrine will **only** check the owning side of an association for changes.
-
-Bidirectional Associations
---------------------------
-
-The following rules apply to **bidirectional** associations:
-
-- The inverse side has to have the ``mappedBy`` attribute of the OneToOne,
-  OneToMany, or ManyToMany mapping declaration. The mappedBy
-  attribute contains the name of the association-field on the owning side.
-- The owning side has to have the ``inversedBy`` attribute of the
-  OneToOne, ManyToOne, or ManyToMany mapping declaration. 
-  The inversedBy attribute contains the name of the association-field
-  on the inverse-side.
-- ManyToOne is always the owning side of a bidirectional association.
-- OneToMany is always the inverse side of a bidirectional association.
-- The owning side of a OneToOne association is the entity with the table
-  containing the foreign key.
-- You can pick the owning side of a many-to-many association yourself.
-
-Important concepts
-------------------
-
-**Doctrine will only check the owning side of an association for changes.**
-
-To fully understand this, remember how bidirectional associations
-are maintained in the object world. There are 2 references on each
-side of the association and these 2 references both represent the
-same association but can change independently of one another. Of
-course, in a correct application the semantics of the bidirectional
-association are properly maintained by the application developer
-(that's their responsibility). Doctrine needs to know which of these
-two in-memory references is the one that should be persisted and
-which not. This is what the owning/inverse concept is mainly used
-for.
-
-**Changes made only to the inverse side of an association are ignored. Make sure to update both sides of a bidirectional association (or at least the owning side, from Doctrine's point of view)**
-
-The owning side of a bidirectional association is the side Doctrine
-"looks at" when determining the state of the association, and
-consequently whether there is anything to do to update the
-association in the database.
-
-.. note::
-
-    "Owning side" and "inverse side" are technical concepts of
-    the ORM technology, not concepts of your domain model. What you
-    consider as the owning side in your domain model can be different
-    from what the owning side is for Doctrine. These are unrelated.

-Doctrine Internals explained
-============================
-
-Object relational mapping is a complex topic and sufficiently understanding how Doctrine works internally helps you use its full power.
-
-How Doctrine keeps track of Objects
------------------------------------
-
-Doctrine uses the Identity Map pattern to track objects. Whenever you fetch an
-object from the database, Doctrine will keep a reference to this object inside
-its UnitOfWork. The array holding all the entity references is two-levels deep
-and has the keys "root entity name" and "id". Since Doctrine allows composite
-keys the id is a sorted, serialized version of all the key columns.
-
-This allows Doctrine room for optimizations. If you call the EntityManager and
-ask for an entity with a specific ID twice, it will return the same instance:
-
-.. code-block:: php
-
-    public function testIdentityMap()
-    {
-        $objectA = $this->entityManager->find('EntityName', 1);
-        $objectB = $this->entityManager->find('EntityName', 1);
-
-        $this->assertSame($objectA, $objectB)
-    }
-
-Only one SELECT query will be fired against the database here. In the second
-``EntityManager#find()`` call Doctrine will check the identity map first and
-doesn't need to make that database roundtrip.
-
-Even if you get a proxy object first then fetch the object by the same id you
-will still end up with the same reference:
-
-.. code-block:: php
-
-    public function testIdentityMapReference()
-    {
-        $objectA = $this->entityManager->getReference('EntityName', 1);
-        // check for proxyinterface
-        $this->assertInstanceOf('Doctrine\ORM\Proxy\Proxy', $objectA);
-
-        $objectB = $this->entityManager->find('EntityName', 1);
-
-        $this->assertSame($objectA, $objectB)
-    }
-
-The identity map being indexed by primary keys only allows shortcuts when you
-ask for objects by primary key. Assume you have the following ``persons``
-table:
-
-::
-
-    id | name
-    -------------
-    1  | Benjamin
-    2  | Bud
-
-Take the following example where two
-consecutive calls are made against a repository to fetch an entity by a set of
-criteria:
-
-.. code-block:: php
-
-    public function testIdentityMapRepositoryFindBy()
-    {
-        $repository = $this->entityManager->getRepository('Person');
-        $objectA = $repository->findOneBy(array('name' => 'Benjamin'));
-        $objectB = $repository->findOneBy(array('name' => 'Benjamin'));
-
-        $this->assertSame($objectA, $objectB);
-    }
-
-This query will still return the same references and `$objectA` and `$objectB`
-are indeed referencing the same object. However when checking your SQL logs you
-will realize that two queries have been executed against the database. Doctrine
-only knows objects by id, so a query for different criteria has to go to the
-database, even if it was executed just before.
-
-But instead of creating a second Person object Doctrine first gets the primary
-key from the row and check if it already has an object inside the UnitOfWork
-with that primary key. In our example it finds an object and decides to return
-this instead of creating a new one.
-
-The identity map has a second use-case. When you call ``EntityManager#flush``
-Doctrine will ask the identity map for all objects that are currently managed.
-This means you don't have to call ``EntityManager#persist`` over and over again
-to pass known objects to the EntityManager. This is a NO-OP for known entities,
-but leads to much code written that is confusing to other developers.
-
-The following code WILL update your database with the changes made to the
-``Person`` object, even if you did not call ``EntityManager#persist``:
-
-.. code-block:: php
-
-    <?php
-    $user = $entityManager->find("Person", 1);
-    $user->setName("Guilherme");
-    $entityManager->flush();
-
-How Doctrine Detects Changes
-----------------------------
-
-Doctrine is a data-mapper that tries to achieve persistence-ignorance (PI).
-This means you map php objects into a relational database that don't
-necessarily know about the database at all. A natural question would now be,
-"how does Doctrine even detect objects have changed?". 
-
-For this Doctrine keeps a second map inside the UnitOfWork. Whenever you fetch
-an object from the database Doctrine will keep a copy of all the properties and
-associations inside the UnitOfWork. Because variables in the PHP language are
-subject to "copy-on-write" the memory usage of a PHP request that only reads
-objects from the database is the same as if Doctrine did not keep this variable
-copy. Only if you start changing variables PHP will create new variables internally
-that consume new memory.
-
-Now whenever you call ``EntityManager#flush`` Doctrine will iterate over the
-Identity Map and for each object compares the original property and association
-values with the values that are currently set on the object. If changes are
-detected then the object is queued for a SQL UPDATE operation. Only the fields
-that actually changed are updated.
-
-This process has an obvious performance impact. The larger the size of the
-UnitOfWork is, the longer this computation takes. There are several ways to
-optimize the performance of the Flush Operation:
-
-- Mark entities as read only. These entities can only be inserted or removed,
-  but are never updated. They are omitted in the changeset calculation.
-- Temporarily mark entities as read only. If you have a very large UnitOfWork
-  but know that a large set of entities has not changed, just mark them as read
-  only with ``$entityManager->getUnitOfWork()->markReadOnly($entity)``.
-- Flush only a single entity with ``$entityManager->flush($entity)``.
-- Use :doc:`Change Tracking Policies <change-tracking-policies>` to use more
-  explicit strategies of notifying the UnitOfWork what objects/properties
-  changed.
-
-
-Query Internals
----------------
-
-The different ORM Layers
-------------------------
-
-Doctrine ships with a set of layers with different responsibilities. This
-section gives a short explanation of each layer.
-
-Hydration
-~~~~~~~~~
-
-Responsible for creating a final result from a raw database statement and a
-result-set mapping object. The developer can choose which kind of result they
-wish to be hydrated. Default result-types include:
-
-- SQL to Entities
-- SQL to structured Arrays
-- SQL to simple scalar result arrays
-- SQL to a single result variable
-
-Hydration to entities and arrays is one of the most complex parts of Doctrine
-algorithm-wise. It can build results with for example:
-
-- Single table selects
-- Joins with n:1 or 1:n cardinality, grouping belonging to the same parent.
-- Mixed results of objects and scalar values
-- Hydration of results by a given scalar value as key.

-Working with Associations
-=========================
-
-Associations between entities are represented just like in regular
-object-oriented PHP code using references to other objects or
-collections of objects.
-
-Changes to associations in your code are not synchronized to the
-database directly, only when calling ``EntityManager#flush()``.
-
-There are other concepts you should know about when working
-with associations in Doctrine:
-
--  If an entity is removed from a collection, the association is
-   removed, not the entity itself. A collection of entities always
-   only represents the association to the containing entities, not the
-   entity itself.
--  When a bidirectional association is updated, Doctrine only checks
-   on one of both sides for these changes. This is called the :doc:`owning side <unitofwork-associations>`
-   of the association.
--  A property with a reference to many entities has to be instances of the
-   ``Doctrine\Common\Collections\Collection`` interface.
-
-Association Example Entities
-----------------------------
-
-We will use a simple comment system with Users and Comments as
-entities to show examples of association management. See the PHP
-docblocks of each association in the following example for
-information about its type and if it's the owning or inverse side.

-This two entities generate the following MySQL Schema (Foreign Key
-definitions omitted):

-        id VARCHAR(255) NOT NULL,
-        firstComment_id VARCHAR(255) DEFAULT NULL,

-Establishing an association between two entities is

-    class User
-    {
-        // ...
-        public function getReadComments() {
-             return $this->commentsRead;
-        }
-    
-        public function setFirstComment(Comment $c) {
-            $this->firstComment = $c;
-        }
-    }
-
-The interaction code would then look like in the following snippet
-(``$em`` here is an instance of the EntityManager):
-
-.. code-block:: php
-
-    <?php
-    $user = $em->find('User', $userId);
-    
-    // unidirectional many to many
-    $comment = $em->find('Comment', $readCommentId);
-    $user->getReadComments()->add($comment);
-    
-    $em->flush();
-    
-    // unidirectional many to one
-    $myFirstComment = new Comment();
-    $user->setFirstComment($myFirstComment);
-    
-    $em->persist($myFirstComment);
-    $em->flush();
-
-In the case of bi-directional associations you have to update the
-fields on both sides:
-
-.. code-block:: php
-
-    <?php
-    class User
-    {
-        // ..
-    
-        public function getAuthoredComments() {
-            return $this->commentsAuthored;
-        }
-    
-        public function getFavoriteComments() {
-            return $this->favorites;
-        }
-    }
-    
-    class Comment
-    {
-        // ...
-    
-        public function getUserFavorites() {
-            return $this->userFavorites;
-        }
-    
-        public function setAuthor(User $author = null) {
-            $this->author = $author;
-        }
-    }
-    
-    // Many-to-Many
-    $user->getFavorites()->add($favoriteComment);
-    $favoriteComment->getUserFavorites()->add($user);
-    
-    $em->flush();
-    
-    // Many-To-One / One-To-Many Bidirectional
-    $newComment = new Comment();
-    $user->getAuthoredComments()->add($newComment);
-    $newComment->setAuthor($user);
-    
-    $em->persist($newComment);
-    $em->flush();
-
-Notice how always both sides of the bidirectional association are
-updated. The previous unidirectional associations were simpler to
-handle.
-
-Removing Associations
----------------------
-
-Removing an association between two entities is similarly
-straight-forward. There are two strategies to do so, by key and by
-element. Here are some examples:
-
-.. code-block:: php
-
-    <?php
-    // Remove by Elements
-    $user->getComments()->removeElement($comment);
-    $comment->setAuthor(null);
-    
-    $user->getFavorites()->removeElement($comment);
-    $comment->getUserFavorites()->removeElement($user);
-    
-    // Remove by Key
-    $user->getComments()->remove($ithComment);
-    $comment->setAuthor(null);
-
-You need to call ``$em->flush()`` to make persist these changes in
-the database permanently.
-
-Notice how both sides of the bidirectional association are always
-updated. Unidirectional associations are consequently simpler to
-handle.
-
-Also note that if you use type-hinting in your methods, you will 
-have to specify a nullable type, i.e. ``setAddress(?Address $address)``,
-otherwise ``setAddress(null)`` will fail to remove the association.
-Another way to deal with this is to provide a special method, like
-``removeAddress()``. This can also provide better encapsulation as
-it hides the internal meaning of not having an address.
-
-When working with collections, keep in mind that a Collection is
-essentially an ordered map (just like a PHP array). That is why the
-``remove`` operation accepts an index/key. ``removeElement`` is a
-separate method that has O(n) complexity using ``array_search``,
-where n is the size of the map.
-
-.. note::
-
-    Since Doctrine always only looks at the owning side of a
-    bidirectional association for updates, it is not necessary for
-    write operations that an inverse collection of a bidirectional
-    one-to-many or many-to-many association is updated. This knowledge
-    can often be used to improve performance by avoiding the loading of
-    the inverse collection.
-
-
-You can also clear the contents of a whole collection using the
-``Collections::clear()`` method. You should be aware that using
-this method can lead to a straight and optimized database delete or
-update call during the flush operation that is not aware of
-entities that have been re-added to the collection.
-
-Say you clear a collection of tags by calling
-``$post->getTags()->clear();`` and then call
-``$post->getTags()->add($tag)``. This will not recognize the tag having 
-already been added previously and will consequently issue two separate database 
-calls.
-
-Association Management Methods
-------------------------------
-
-It is generally a good idea to encapsulate proper association
-management inside the entity classes. This makes it easier to use
-the class correctly and can encapsulate details about how the
-association is maintained.
-
-The following code shows updates to the previous User and Comment
-example that encapsulate much of the association management code:
-
-.. code-block:: php
-
-    <?php
-    class User
-    {
-        //...
-        public function markCommentRead(Comment $comment) {
-            // Collections implement ArrayAccess
-            $this->commentsRead[] = $comment;
-        }
-    
-        public function addComment(Comment $comment) {
-            if (count($this->commentsAuthored) == 0) {
-                $this->setFirstComment($comment);
-            }
-            $this->comments[] = $comment;
-            $comment->setAuthor($this);
-        }
-    
-        private function setFirstComment(Comment $c) {
-            $this->firstComment = $c;
-        }
-    
-        public function addFavorite(Comment $comment) {
-            $this->favorites->add($comment);
-            $comment->addUserFavorite($this);
-        }
-    
-        public function removeFavorite(Comment $comment) {
-            $this->favorites->removeElement($comment);
-            $comment->removeUserFavorite($this);
-        }
-    }
-    
-    class Comment
-    {
-        // ..
-    
-        public function addUserFavorite(User $user) {
-            $this->userFavorites[] = $user;
-        }
-    
-        public function removeUserFavorite(User $user) {
-            $this->userFavorites->removeElement($user);
-        }
-    }
-
-You will notice that ``addUserFavorite`` and ``removeUserFavorite``
-do not call ``addFavorite`` and ``removeFavorite``, thus the
-bidirectional association is strictly-speaking still incomplete.
-However if you would naively add the ``addFavorite`` in
-``addUserFavorite``, you end up with an infinite loop, so more work
-is needed. As you can see, proper bidirectional association
-management in plain OOP is a non-trivial task and encapsulating all
-the details inside the classes can be challenging.
-
-.. note::
-
-    If you want to make sure that your collections are perfectly
-    encapsulated you should not return them from a
-    ``getCollectionName()`` method directly, but call
-    ``$collection->toArray()``. This way a client programmer for the
-    entity cannot circumvent the logic you implement on your entity for
-    association management. For example:
-
-
-.. code-block:: php
-
-    <?php
-    class User {
-        public function getReadComments() {
-            return $this->commentsRead->toArray();
-        }
-    }
-
-This will however always initialize the collection, with all the
-performance penalties given the size. In some scenarios of large
-collections it might even be a good idea to completely hide the
-read access behind methods on the EntityRepository.
-
-There is no single, best way for association management. It greatly
-depends on the requirements of your concrete domain model as well
-as your preferences.
-
-Synchronizing Bidirectional Collections
----------------------------------------
-
-In the case of Many-To-Many associations you as the developer have the 
-responsibility of keeping the collections on the owning and inverse side
-in sync when you apply changes to them. Doctrine can only
-guarantee a consistent state for the hydration, not for your client
-code.
-
-Using the User-Comment entities from above, a very simple example
-can show the possible caveats you can encounter:
-
-.. code-block:: php
-
-    <?php
-    $user->getFavorites()->add($favoriteComment);
-    // not calling $favoriteComment->getUserFavorites()->add($user);
-    
-    $user->getFavorites()->contains($favoriteComment); // TRUE
-    $favoriteComment->getUserFavorites()->contains($user); // FALSE
-
-There are two approaches to handle this problem in your code:
-
-
-1. Ignore updating the inverse side of bidirectional collections,
-   BUT never read from them in requests that changed their state. In
-   the next request Doctrine hydrates the consistent collection state
-   again.
-2. Always keep the bidirectional collections in sync through
-   association management methods. Reads of the Collections directly
-   after changes are consistent then.
-
-.. _transitive-persistence:
-
-Transitive persistence / Cascade Operations
--------------------------------------------
-
-Doctrine ORM provides a mechanism for transitive persistence through cascading of certain operations.
-Each association to another entity or a collection of
-entities can be configured to automatically cascade the following operations to the associated entities:
-``persist``, ``remove``, ``merge``, ``detach``, ``refresh`` or ``all``.
-
-The main use case for ``cascade: persist`` is to avoid "exposing" associated entities to your PHP application.
-Continuing with the User-Comment example of this chapter, this is how the creation of a new user and a new
-comment might look like in your controller (without ``cascade: persist``):
-
-.. code-block:: php
-
-    <?php
-    $user = new User();
-    $myFirstComment = new Comment();
-    $user->addComment($myFirstComment);
-    
-    $em->persist($user);
-    $em->persist($myFirstComment); // required, if `cascade: persist` is not set
-    $em->flush();
-
-Note that the Comment entity is instantiated right here in the controller.
-To avoid this, ``cascade: persist`` allows you to "hide" the Comment entity from the controller,
-only accessing it through the User entity:
-
-.. code-block:: php
-
-    <?php
-    // User entity
-    class User
-    {
-        private $id;
-        private $comments;
-
-        public function __construct()
-        {
-            $this->id = User::new();
-            $this->comments = new ArrayCollection();
-        }
-
-        public function comment(string $text, DateTimeInterface $time) : void
-        {
-            $newComment = Comment::create($text, $time);
-            $newComment->setUser($this);
-            $this->comments->add($newComment);
-        }
-
-        // ...
-    }
-
-If you then set up the cascading to the ``User#commentsAuthored`` property...
-
-.. code-block:: php
-
-    <?php
-    class User
-    {
-        //...
-        /**
-         * Bidirectional - One-To-Many (INVERSE SIDE)
-         *
-         * @OneToMany(targetEntity="Comment", mappedBy="author", cascade={"persist", "remove"})
-         */
-        private $commentsAuthored;
-        //...
-    }
-
-...you can now create a user and an associated comment like this:
-
-.. code-block:: php
-
-    <?php
-    $user = new User();
-    $user->comment('Lorem ipsum', new DateTime());
-    
-    $em->persist($user);
-    $em->flush();
-
-.. note::
-
-    The idea of ``cascade: persist`` is not to save you any lines of code in the controller.
-    If you instantiate the comment object in the controller (i.e. don't set up the user entity as shown above),
-    even with ``cascade: persist`` you still have to call ``$myFirstComment->setUser($user);``.
-
-Thanks to ``cascade: remove``, you can easily delete a user and all linked comments without having to loop through them:
-
-.. code-block:: php
-
-    <?php
-    $user = $em->find('User', $deleteUserId);
-
-    $em->remove($user);
-    $em->flush();
-
-.. note::
-
-    Cascade operations are performed in memory. That means collections and related entities
-    are fetched into memory (even if they are marked as lazy) when
-    the cascade operation is about to be performed. This approach allows
-    entity lifecycle events to be performed for each of these operations.
-
-    However, pulling object graphs into memory on cascade can cause considerable performance
-    overhead, especially when the cascaded collections are large. Make sure
-    to weigh the benefits and downsides of each cascade operation that you define.
-
-    To rely on the database level cascade operations for the delete operation instead, you can
-    configure each join column with :doc:`the onDelete option <working-with-objects>`.
-
-Even though automatic cascading is convenient, it should be used
-with care. Do not blindly apply ``cascade=all`` to all associations as
-it will unnecessarily degrade the performance of your application.
-For each cascade operation that gets activated, Doctrine also
-applies that operation to the association, be it single or
-collection valued.
-
-Persistence by Reachability: Cascade Persist
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are additional semantics that apply to the Cascade Persist
-operation. During each ``flush()`` operation Doctrine detects if there
-are new entities in any collection and three possible cases can
-happen:
-
-
-1. New entities in a collection marked as ``cascade: persist`` will be
-   directly persisted by Doctrine.
-2. New entities in a collection not marked as ``cascade: persist`` will
-   produce an Exception and rollback the ``flush()`` operation.
-3. Collections without new entities are skipped.
-
-This concept is called Persistence by Reachability: New entities
-that are found on already managed entities are automatically
-persisted as long as the association is defined as ``cascade: persist``.
-
-Orphan Removal
---------------
-
-There is another concept of cascading that is relevant only when removing entities
-from collections. If an Entity of type ``A`` contains references to privately
-owned Entities ``B`` then if the reference from ``A`` to ``B`` is removed the
-entity ``B`` should also be removed, because it is not used anymore.
-
-OrphanRemoval works with one-to-one, one-to-many and many-to-many associations.
-
-.. note::
-
-    When using the ``orphanRemoval=true`` option Doctrine makes the assumption
-    that the entities are privately owned and will **NOT** be reused by other entities.
-    If you neglect this assumption your entities will get deleted by Doctrine even if
-    you assigned the orphaned entity to another one.
-
-As a better example consider an Addressbook application where you have Contacts, Addresses
-and StandingData:
-
-.. code-block:: php
-
-    <?php
-
-    namespace Addressbook;
-
-    use Doctrine\Common\Collections\ArrayCollection;
-
-    /**
-     * @Entity
-     */
-    class Contact
-    {
-        /** @Id @Column(type="integer") @GeneratedValue */
-        private $id;
-
-        /** @OneToOne(targetEntity="StandingData", orphanRemoval=true) */
-        private $standingData;
-
-        /** @OneToMany(targetEntity="Address", mappedBy="contact", orphanRemoval=true) */
-        private $addresses;
-
-        public function __construct()
-        {
-            $this->addresses = new ArrayCollection();
-        }
-
-        public function newStandingData(StandingData $sd)
-        {
-            $this->standingData = $sd;
-        }
-
-        public function removeAddress($pos)
-        {
-            unset($this->addresses[$pos]);
-        }
-    }
-
-Now two examples of what happens when you remove the references:
-
-.. code-block:: php
-
-    <?php
-
-    $contact = $em->find("Addressbook\Contact", $contactId);
-    $contact->newStandingData(new StandingData("Firstname", "Lastname", "Street"));
-    $contact->removeAddress(1);
-
-    $em->flush();
-
-In this case you have not only changed the ``Contact`` entity itself but 
-you have also removed the references for standing data and as well as one 
-address reference. When flush is called not only are the references removed 
-but both the old standing data and the one address entity are also deleted 
-from the database.
-
-.. _filtering-collections:
-
-Filtering Collections
----------------------
-
-Collections have a filtering API that allows to slice parts of data from
-a collection. If the collection has not been loaded from the database yet,
-the filtering API can work on the SQL level to make optimized access to
-large collections.
-
-.. code-block:: php
-
-    <?php
-
-    use Doctrine\Common\Collections\Criteria;
-
-    $group          = $entityManager->find('Group', $groupId);
-    $userCollection = $group->getUsers();
-
-    $criteria = Criteria::create()
-        ->where(Criteria::expr()->eq("birthday", "1982-02-17"))
-        ->orderBy(array("username" => Criteria::ASC))
-        ->setFirstResult(0)
-        ->setMaxResults(20)
-    ;
-
-    $birthdayUsers = $userCollection->matching($criteria);
-
-.. tip::
-
-    You can move the access of slices of collections into dedicated methods of
-    an entity. For example ``Group#getTodaysBirthdayUsers()``.
-
-The Criteria has a limited matching language that works both on the
-SQL and on the PHP collection level. This means you can use collection matching
-interchangeably, independent of in-memory or sql-backed collections.
-
-.. code-block:: php
-
-    <?php
-
-    use Doctrine\Common\Collections;
-
-    class Criteria
-    {
-        /**
-         * @return Criteria
-         */
-        static public function create();
-        /**
-         * @param Expression $where
-         * @return Criteria
-         */
-        public function where(Expression $where);
-        /**
-         * @param Expression $where
-         * @return Criteria
-         */
-        public function andWhere(Expression $where);
-        /**
-         * @param Expression $where
-         * @return Criteria
-         */
-        public function orWhere(Expression $where);
-        /**
-         * @param array $orderings
-         * @return Criteria
-         */
-        public function orderBy(array $orderings);
-        /**
-         * @param int $firstResult
-         * @return Criteria
-         */
-        public function setFirstResult($firstResult);
-        /**
-         * @param int $maxResults
-         * @return Criteria
-         */
-        public function setMaxResults($maxResults);
-        public function getOrderings();
-        public function getWhereExpression();
-        public function getFirstResult();
-        public function getMaxResults();
-    }
-
-You can build expressions through the ExpressionBuilder. It has the following
-methods:
-
-* ``andX($arg1, $arg2, ...)``
-* ``orX($arg1, $arg2, ...)``
-* ``eq($field, $value)``
-* ``gt($field, $value)``
-* ``lt($field, $value)``
-* ``lte($field, $value)``
-* ``gte($field, $value)``
-* ``neq($field, $value)``
-* ``isNull($field)``
-* ``in($field, array $values)``
-* ``notIn($field, array $values)``
-* ``contains($field, $value)``
-* ``memberOf($value, $field)``
-* ``startsWith($field, $value)``
-* ``endsWith($field, $value)``
-
-
-.. note::
-
-    There is a limitation on the compatibility of Criteria comparisons.
-    You have to use scalar values only as the value in a comparison or
-    the behaviour between different backends is not the same.

-Working with Objects
-====================
-
-In this chapter we will help you understand the ``EntityManager``
-and the ``UnitOfWork``. A Unit of Work is similar to an
-object-level transaction. A new Unit of Work is implicitly started
-when an EntityManager is initially created or after
-``EntityManager#flush()`` has been invoked. A Unit of Work is
-committed (and a new one started) by invoking
-``EntityManager#flush()``.
-
-A Unit of Work can be manually closed by calling
-EntityManager#close(). Any changes to objects within this Unit of
-Work that have not yet been persisted are lost.
-
-.. note::
-
-    It is very important to understand that only
-    ``EntityManager#flush()`` ever causes write operations against the
-    database to be executed. Any other methods such as
-    ``EntityManager#persist($entity)`` or
-    ``EntityManager#remove($entity)`` only notify the UnitOfWork to
-    perform these operations during flush.
-
-    Not calling ``EntityManager#flush()`` will lead to all changes
-    during that request being lost.
-
-.. note::
-
-    Doctrine does NEVER touch the public API of methods in your entity
-    classes (like getters and setters) nor the constructor method.
-    Instead, it uses reflection to get/set data from/to your entity objects.
-    When Doctrine fetches data from DB and saves it back,
-    any code put in your get/set methods won't be implicitly taken into account.
-
-Entities and the Identity Map
------------------------------
-
-Entities are objects with identity. Their identity has a conceptual
-meaning inside your domain. In a CMS application each article has a
-unique id. You can uniquely identify each article by that id.
-
-Take the following example, where you find an article with the
-headline "Hello World" with the ID 1234:
-
-.. code-block:: php
-
-    <?php
-    $article = $entityManager->find('CMS\Article', 1234);
-    $article->setHeadline('Hello World dude!');
-
-    $article2 = $entityManager->find('CMS\Article', 1234);
-    echo $article2->getHeadline();
-
-In this case the Article is accessed from the entity manager twice,
-but modified in between. Doctrine ORM realizes this and will only
-ever give you access to one instance of the Article with ID 1234,
-no matter how often do you retrieve it from the EntityManager and
-even no matter what kind of Query method you are using (find,
-Repository Finder or DQL). This is called "Identity Map" pattern,
-which means Doctrine keeps a map of each entity and ids that have
-been retrieved per PHP request and keeps returning you the same
-instances.
-
-In the previous example the echo prints "Hello World dude!" to the
-screen. You can even verify that ``$article`` and ``$article2`` are
-indeed pointing to the same instance by running the following
-code:
-
-.. code-block:: php
-
-    <?php
-    if ($article === $article2) {
-        echo "Yes we are the same!";
-    }
-
-Sometimes you want to clear the identity map of an EntityManager to
-start over. We use this regularly in our unit-tests to enforce
-loading objects from the database again instead of serving them
-from the identity map. You can call ``EntityManager#clear()`` to
-achieve this result.
-
-Entity Object Graph Traversal
------------------------------
-
-Although Doctrine allows for a complete separation of your domain
-model (Entity classes) there will never be a situation where
-objects are "missing" when traversing associations. You can walk
-all the associations inside your entity models as deep as you
-want.
-
-Take the following example of a single ``Article`` entity fetched
-from newly opened EntityManager.
-
-.. code-block:: php
-
-    <?php
-    /** @Entity */
-    class Article
-    {
-        /** @Id @Column(type="integer") @GeneratedValue */
-        private $id;
-
-        /** @Column(type="string") */
-        private $headline;
-
-        /** @ManyToOne(targetEntity="User") */
-        private $author;
-
-        /** @OneToMany(targetEntity="Comment", mappedBy="article") */
-        private $comments;
-
-        public function __construct()
-        {
-            $this->comments = new ArrayCollection();
-        }
-
-        public function getAuthor() { return $this->author; }
-        public function getComments() { return $this->comments; }
-    }
-
-    $article = $em->find('Article', 1);
-
-This code only retrieves the ``Article`` instance with id 1 executing
-a single SELECT statement against the articles table in the database.
-You can still access the associated properties author and comments
-and the associated objects they contain.
-
-This works by utilizing the lazy loading pattern. Instead of
-passing you back a real Author instance and a collection of
-comments Doctrine will create proxy instances for you. Only if you
-access these proxies for the first time they will go through the
-EntityManager and load their state from the database.
-
-This lazy-loading process happens behind the scenes, hidden from
-your code. See the following code:
-
-.. code-block:: php
-
-    <?php
-    $article = $em->find('Article', 1);
-
-    // accessing a method of the user instance triggers the lazy-load
-    echo "Author: " . $article->getAuthor()->getName() . "\n";
-
-    // Lazy Loading Proxies pass instanceof tests:
-    if ($article->getAuthor() instanceof User) {
-        // a User Proxy is a generated "UserProxy" class
-    }
-
-    // accessing the comments as an iterator triggers the lazy-load
-    // retrieving ALL the comments of this article from the database
-    // using a single SELECT statement
-    foreach ($article->getComments() as $comment) {
-        echo $comment->getText() . "\n\n";
-    }
-
-    // Article::$comments passes instanceof tests for the Collection interface
-    // But it will NOT pass for the ArrayCollection interface
-    if ($article->getComments() instanceof \Doctrine\Common\Collections\Collection) {
-        echo "This will always be true!";
-    }
-
-A slice of the generated proxy classes code looks like the
-following piece of code. A real proxy class override ALL public
-methods along the lines of the ``getName()`` method shown below:
-
-.. code-block:: php
-
-    <?php
-    class UserProxy extends User implements Proxy
-    {
-        private function _load()
-        {
-            // lazy loading code
-        }
-
-        public function getName()
-        {
-            $this->_load();
-            return parent::getName();
-        }
-        // .. other public methods of User
-    }
-
-.. warning::
-
-    Traversing the object graph for parts that are lazy-loaded will
-    easily trigger lots of SQL queries and will perform badly if used
-    to heavily. Make sure to use DQL to fetch-join all the parts of the
-    object-graph that you need as efficiently as possible.
-
-
-Persisting entities
--------------------
-
-An entity can be made persistent by passing it to the
-``EntityManager#persist($entity)`` method. By applying the persist
-operation on some entity, that entity becomes MANAGED, which means
-that its persistence is from now on managed by an EntityManager. As
-a result the persistent state of such an entity will subsequently
-be properly synchronized with the database when
-``EntityManager#flush()`` is invoked.
-
-.. note::
-
-    Invoking the ``persist`` method on an entity does NOT
-    cause an immediate SQL INSERT to be issued on the database.
-    Doctrine applies a strategy called "transactional write-behind",
-    which means that it will delay most SQL commands until
-    ``EntityManager#flush()`` is invoked which will then issue all
-    necessary SQL statements to synchronize your objects with the
-    database in the most efficient way and a single, short transaction,
-    taking care of maintaining referential integrity.
-
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    $user = new User;
-    $user->setName('Mr.Right');
-    $em->persist($user);
-    $em->flush();
-
-.. note::
-
-    Generated entity identifiers / primary keys are
-    guaranteed to be available after the next successful flush
-    operation that involves the entity in question. You can not rely on
-    a generated identifier to be available directly after invoking
-    ``persist``. The inverse is also true. You can not rely on a
-    generated identifier being not available after a failed flush
-    operation.
-
-
-The semantics of the persist operation, applied on an entity X, are
-as follows:
-
-
--  If X is a new entity, it becomes managed. The entity X will be
-   entered into the database as a result of the flush operation.
--  If X is a preexisting managed entity, it is ignored by the
-   persist operation. However, the persist operation is cascaded to
-   entities referenced by X, if the relationships from X to these
-   other entities are mapped with cascade=PERSIST or cascade=ALL (see
-   ":ref:`transitive-persistence`").
--  If X is a removed entity, it becomes managed.
--  If X is a detached entity, an exception will be thrown on
-   flush.
-
-.. caution::
-
-    Do not pass detached entities to the persist operation. The persist operation always
-    considers entities that are not yet known to the ``EntityManager`` as new entities
-    (refer to the ``STATE_NEW`` constant inside the ``UnitOfWork``).
-
-Removing entities
------------------
-
-An entity can be removed from persistent storage by passing it to
-the ``EntityManager#remove($entity)`` method. By applying the
-``remove`` operation on some entity, that entity becomes REMOVED,
-which means that its persistent state will be deleted once
-``EntityManager#flush()`` is invoked.
-
-.. note::
-
-    Just like ``persist``, invoking ``remove`` on an entity
-    does NOT cause an immediate SQL DELETE to be issued on the
-    database. The entity will be deleted on the next invocation of
-    ``EntityManager#flush()`` that involves that entity. This
-    means that entities scheduled for removal can still be queried
-    for and appear in query and collection results. See
-    the section on :ref:`Database and UnitOfWork Out-Of-Sync <workingobjects_database_uow_outofsync>`
-    for more information.
-
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    $em->remove($user);
-    $em->flush();
-
-The semantics of the remove operation, applied to an entity X are
-as follows:
-
-
--  If X is a new entity, it is ignored by the remove operation.
-   However, the remove operation is cascaded to entities referenced by
-   X, if the relationship from X to these other entities is mapped
-   with cascade=REMOVE or cascade=ALL (see ":ref:`transitive-persistence`").
--  If X is a managed entity, the remove operation causes it to
-   become removed. The remove operation is cascaded to entities
-   referenced by X, if the relationships from X to these other
-   entities is mapped with cascade=REMOVE or cascade=ALL (see
-   ":ref:`transitive-persistence`").
--  If X is a detached entity, an InvalidArgumentException will be
-   thrown.
--  If X is a removed entity, it is ignored by the remove operation.
--  A removed entity X will be removed from the database as a result
-   of the flush operation.
-
-After an entity has been removed its in-memory state is the same as
-before the removal, except for generated identifiers.
-
-Removing an entity will also automatically delete any existing
-records in many-to-many join tables that link this entity. The
-action taken depends on the value of the ``@joinColumn`` mapping
-attribute "onDelete". Either Doctrine issues a dedicated ``DELETE``
-statement for records of each join table or it depends on the
-foreign key semantics of onDelete="CASCADE".
-
-Deleting an object with all its associated objects can be achieved
-in multiple ways with very different performance impacts.
-
-
-1. If an association is marked as ``CASCADE=REMOVE`` Doctrine ORM
-   will fetch this association. If its a Single association it will
-   pass this entity to
-   ``EntityManager#remove()``. If the association is a collection, Doctrine will loop over all    its elements and pass them to``EntityManager#remove()``.
-   In both cases the cascade remove semantics are applied recursively.
-   For large object graphs this removal strategy can be very costly.
-2. Using a DQL ``DELETE`` statement allows you to delete multiple
-   entities of a type with a single command and without hydrating
-   these entities. This can be very efficient to delete large object
-   graphs from the database.
-3. Using foreign key semantics ``onDelete="CASCADE"`` can force the
-   database to remove all associated objects internally. This strategy
-   is a bit tricky to get right but can be very powerful and fast. You
-   should be aware however that using strategy 1 (``CASCADE=REMOVE``)
-   completely by-passes any foreign key ``onDelete=CASCADE`` option,
-   because Doctrine will fetch and remove all associated entities
-   explicitly nevertheless.
-
-.. note::
-
-    Calling ``remove`` on an entity will remove the object from the identiy
-    map and therefore detach it. Querying the same entity again, for example 
-    via a lazy loaded relation, will return a new object. 
-
-
-Detaching entities
-------------------
-
-An entity is detached from an EntityManager and thus no longer
-managed by invoking the ``EntityManager#detach($entity)`` method on
-it or by cascading the detach operation to it. Changes made to the
-detached entity, if any (including removal of the entity), will not
-be synchronized to the database after the entity has been
-detached.
-
-Doctrine will not hold on to any references to a detached entity.
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    $em->detach($entity);
-
-The semantics of the detach operation, applied to an entity X are
-as follows:
-
-
--  If X is a managed entity, the detach operation causes it to
-   become detached. The detach operation is cascaded to entities
-   referenced by X, if the relationships from X to these other
-   entities is mapped with cascade=DETACH or cascade=ALL (see
-   ":ref:`transitive-persistence`"). Entities which previously referenced X
-   will continue to reference X.
--  If X is a new or detached entity, it is ignored by the detach
-   operation.
--  If X is a removed entity, the detach operation is cascaded to
-   entities referenced by X, if the relationships from X to these
-   other entities is mapped with cascade=DETACH or cascade=ALL (see
-   ":ref:`transitive-persistence`"). Entities which previously referenced X
-   will continue to reference X.
-
-There are several situations in which an entity is detached
-automatically without invoking the ``detach`` method:
-
-
--  When ``EntityManager#clear()`` is invoked, all entities that are
-   currently managed by the EntityManager instance become detached.
--  When serializing an entity. The entity retrieved upon subsequent
-   unserialization will be detached (This is the case for all entities
-   that are serialized and stored in some cache, i.e. when using the
-   Query Result Cache).
-
-The ``detach`` operation is usually not as frequently needed and
-used as ``persist`` and ``remove``.
-
-Merging entities
-----------------
-
-Merging entities refers to the merging of (usually detached)
-entities into the context of an EntityManager so that they become
-managed again. To merge the state of an entity into an
-EntityManager use the ``EntityManager#merge($entity)`` method. The
-state of the passed entity will be merged into a managed copy of
-this entity and this copy will subsequently be returned.
-
-Example:
-
-.. code-block:: php
-
-    <?php
-    $detachedEntity = unserialize($serializedEntity); // some detached entity
-    $entity = $em->merge($detachedEntity);
-    // $entity now refers to the fully managed copy returned by the merge operation.
-    // The EntityManager $em now manages the persistence of $entity as usual.
-
-.. note::
-
-    When you want to serialize/unserialize entities you
-    have to make all entity properties protected, never private. The
-    reason for this is, if you serialize a class that was a proxy
-    instance before, the private variables won't be serialized and a
-    PHP Notice is thrown.
-
-
-The semantics of the merge operation, applied to an entity X, are
-as follows:
-
-
--  If X is a detached entity, the state of X is copied onto a
-   pre-existing managed entity instance X' of the same identity.
--  If X is a new entity instance, a new managed copy X' will be
-   created and the state of X is copied onto this managed instance.
--  If X is a removed entity instance, an InvalidArgumentException
-   will be thrown.
--  If X is a managed entity, it is ignored by the merge operation,
-   however, the merge operation is cascaded to entities referenced by
-   relationships from X if these relationships have been mapped with
-   the cascade element value MERGE or ALL (see ":ref:`transitive-persistence`").
--  For all entities Y referenced by relationships from X having the
-   cascade element value MERGE or ALL, Y is merged recursively as Y'.
-   For all such Y referenced by X, X' is set to reference Y'. (Note
-   that if X is managed then X is the same object as X'.)
--  If X is an entity merged to X', with a reference to another
-   entity Y, where cascade=MERGE or cascade=ALL is not specified, then
-   navigation of the same association from X' yields a reference to a
-   managed object Y' with the same persistent identity as Y.
-
-The ``merge`` operation will throw an ``OptimisticLockException``
-if the entity being merged uses optimistic locking through a
-version field and the versions of the entity being merged and the
-managed copy don't match. This usually means that the entity has
-been modified while being detached.
-
-The ``merge`` operation is usually not as frequently needed and
-used as ``persist`` and ``remove``. The most common scenario for
-the ``merge`` operation is to reattach entities to an EntityManager
-that come from some cache (and are therefore detached) and you want
-to modify and persist such an entity.
-
-.. warning::
-
-    If you need to perform multiple merges of entities that share certain subparts
-    of their object-graphs and cascade merge, then you have to call ``EntityManager#clear()`` between the
-    successive calls to ``EntityManager#merge()``. Otherwise you might end up with
-    multiple copies of the "same" object in the database, however with different ids.
-
-.. note::
-
-    If you load some detached entities from a cache and you do
-    not need to persist or delete them or otherwise make use of them
-    without the need for persistence services there is no need to use
-    ``merge``. I.e. you can simply pass detached objects from a cache
-    directly to the view.
-
-
-Synchronization with the Database
----------------------------------
-
-The state of persistent entities is synchronized with the database
-on flush of an ``EntityManager`` which commits the underlying
-``UnitOfWork``. The synchronization involves writing any updates to
-persistent entities and their relationships to the database.
-Thereby bidirectional relationships are persisted based on the
-references held by the owning side of the relationship as explained
-in the Association Mapping chapter.
-
-When ``EntityManager#flush()`` is called, Doctrine inspects all
-managed, new and removed entities and will perform the following
-operations.
-
-.. _workingobjects_database_uow_outofsync:
-
-Effects of Database and UnitOfWork being Out-Of-Sync
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-As soon as you begin to change the state of entities, call persist or remove the
-contents of the UnitOfWork and the database will drive out of sync. They can
-only be synchronized by calling ``EntityManager#flush()``. This section
-describes the effects of database and UnitOfWork being out of sync.
-
--  Entities that are scheduled for removal can still be queried from the database.
-   They are returned from DQL and Repository queries and are visible in collections.
--  Entities that are passed to ``EntityManager#persist`` do not turn up in query
-   results.
--  Entities that have changed will not be overwritten with the state from the database.
-   This is because the identity map will detect the construction of an already existing
-   entity and assumes its the most up to date version.
-
-``EntityManager#flush()`` is never called implicitly by Doctrine. You always have to trigger it manually.
-
-Synchronizing New and Managed Entities
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The flush operation applies to a managed entity with the following
-semantics:
-
-
--  The entity itself is synchronized to the database using a SQL
-   UPDATE statement, only if at least one persistent field has
-   changed.
--  No SQL updates are executed if the entity did not change.
-
-The flush operation applies to a new entity with the following
-semantics:
-
-
--  The entity itself is synchronized to the database using a SQL
-   INSERT statement.
-
-For all (initialized) relationships of the new or managed entity
-the following semantics apply to each associated entity X:
-
-
--  If X is new and persist operations are configured to cascade on
-   the relationship, X will be persisted.
--  If X is new and no persist operations are configured to cascade
-   on the relationship, an exception will be thrown as this indicates
-   a programming error.
--  If X is removed and persist operations are configured to cascade
-   on the relationship, an exception will be thrown as this indicates
-   a programming error (X would be re-persisted by the cascade).
--  If X is detached and persist operations are configured to
-   cascade on the relationship, an exception will be thrown (This is
-   semantically the same as passing X to persist()).
-
-Synchronizing Removed Entities
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The flush operation applies to a removed entity by deleting its
-persistent state from the database. No cascade options are relevant
-for removed entities on flush, the cascade remove option is already
-executed during ``EntityManager#remove($entity)``.
-
-The size of a Unit of Work
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The size of a Unit of Work mainly refers to the number of managed
-entities at a particular point in time.
-
-The cost of flushing
-~~~~~~~~~~~~~~~~~~~~
-
-How costly a flush operation is, mainly depends on two factors:
-
-
--  The size of the EntityManager's current UnitOfWork.
--  The configured change tracking policies
-
-You can get the size of a UnitOfWork as follows:
-
-.. code-block:: php
-
-    <?php
-    $uowSize = $em->getUnitOfWork()->size();
-
-The size represents the number of managed entities in the Unit of
-Work. This size affects the performance of flush() operations due
-to change tracking (see "Change Tracking Policies") and, of course,
-memory consumption, so you may want to check it from time to time
-during development.
-
-.. note::
-
-    Do not invoke ``flush`` after every change to an entity
-    or every single invocation of persist/remove/merge/... This is an
-    anti-pattern and unnecessarily reduces the performance of your
-    application. Instead, form units of work that operate on your
-    objects and call ``flush`` when you are done. While serving a
-    single HTTP request there should be usually no need for invoking
-    ``flush`` more than 0-2 times.
-
-
-Direct access to a Unit of Work
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can get direct access to the Unit of Work by calling
-``EntityManager#getUnitOfWork()``. This will return the UnitOfWork
-instance the EntityManager is currently using.
-
-.. code-block:: php
-
-    <?php
-    $uow = $em->getUnitOfWork();
-
-.. note::
-
-    Directly manipulating a UnitOfWork is not recommended.
-    When working directly with the UnitOfWork API, respect methods
-    marked as INTERNAL by not using them and carefully read the API
-    documentation.
-
-
-Entity State
-~~~~~~~~~~~~
-
-As outlined in the architecture overview an entity can be in one of
-four possible states: NEW, MANAGED, REMOVED, DETACHED. If you
-explicitly need to find out what the current state of an entity is
-in the context of a certain ``EntityManager`` you can ask the
-underlying ``UnitOfWork``:
-
-.. code-block:: php
-
-    <?php
-    switch ($em->getUnitOfWork()->getEntityState($entity)) {
-        case UnitOfWork::STATE_MANAGED:
-            ...
-        case UnitOfWork::STATE_REMOVED:
-            ...
-        case UnitOfWork::STATE_DETACHED:
-            ...
-        case UnitOfWork::STATE_NEW:
-            ...
-    }
-
-An entity is in MANAGED state if it is associated with an
-``EntityManager`` and it is not REMOVED.
-
-An entity is in REMOVED state after it has been passed to
-``EntityManager#remove()`` until the next flush operation of the
-same EntityManager. A REMOVED entity is still associated with an
-``EntityManager`` until the next flush operation.
-
-An entity is in DETACHED state if it has persistent state and
-identity but is currently not associated with an
-``EntityManager``.
-
-An entity is in NEW state if has no persistent state and identity
-and is not associated with an ``EntityManager`` (for example those
-just created via the "new" operator).
-
-Querying
---------
-
-Doctrine ORM provides the following ways, in increasing level of
-power and flexibility, to query for persistent objects. You should
-always start with the simplest one that suits your needs.
-
-By Primary Key
-~~~~~~~~~~~~~~
-
-The most basic way to query for a persistent object is by its
-identifier / primary key using the
-``EntityManager#find($entityName, $id)`` method. Here is an
-example:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-    $user = $em->find('MyProject\Domain\User', $id);
-
-The return value is either the found entity instance or null if no
-instance could be found with the given identifier.
-
-Essentially, ``EntityManager#find()`` is just a shortcut for the
-following:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-    $user = $em->getRepository('MyProject\Domain\User')->find($id);
-
-``EntityManager#getRepository($entityName)`` returns a repository
-object which provides many ways to retrieve entities of the
-specified type. By default, the repository instance is of type
-``Doctrine\ORM\EntityRepository``. You can also use custom
-repository classes as shown later.
-
-By Simple Conditions
-~~~~~~~~~~~~~~~~~~~~
-
-To query for one or more entities based on several conditions that
-form a logical conjunction, use the ``findBy`` and ``findOneBy``
-methods on a repository as follows:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-
-    // All users that are 20 years old
-    $users = $em->getRepository('MyProject\Domain\User')->findBy(array('age' => 20));
-
-    // All users that are 20 years old and have a surname of 'Miller'
-    $users = $em->getRepository('MyProject\Domain\User')->findBy(array('age' => 20, 'surname' => 'Miller'));
-
-    // A single user by its nickname
-    $user = $em->getRepository('MyProject\Domain\User')->findOneBy(array('nickname' => 'romanb'));
-
-You can also load by owning side associations through the repository:
-
-.. code-block:: php
-
-    <?php
-    $number = $em->find('MyProject\Domain\Phonenumber', 1234);
-    $user = $em->getRepository('MyProject\Domain\User')->findOneBy(array('phone' => $number->getId()));
-
-The ``EntityRepository#findBy()`` method additionally accepts orderings, limit and offset as second to fourth parameters:
-
-.. code-block:: php
-
-    <?php
-    $tenUsers = $em->getRepository('MyProject\Domain\User')->findBy(array('age' => 20), array('name' => 'ASC'), 10, 0);
-
-If you pass an array of values Doctrine will convert the query into a WHERE field IN (..) query automatically:
-
-.. code-block:: php
-
-    <?php
-    $users = $em->getRepository('MyProject\Domain\User')->findBy(array('age' => array(20, 30, 40)));
-    // translates roughly to: SELECT * FROM users WHERE age IN (20, 30, 40)
-
-An EntityRepository also provides a mechanism for more concise
-calls through its use of ``__call``. Thus, the following two
-examples are equivalent:
-
-.. code-block:: php
-
-    <?php
-    // A single user by its nickname
-    $user = $em->getRepository('MyProject\Domain\User')->findOneBy(array('nickname' => 'romanb'));
-
-    // A single user by its nickname (__call magic)
-    $user = $em->getRepository('MyProject\Domain\User')->findOneByNickname('romanb');
-
-Additionally, you can just count the result of the provided conditions when you don't really need the data:
-
-.. code-block:: php
-
-    <?php
-    // Check there is no user with nickname
-    $availableNickname = 0 === $em->getRepository('MyProject\Domain\User')->count(['nickname' => 'nonexistent']);
-
-By Criteria
-~~~~~~~~~~~
-
-The Repository implement the ``Doctrine\Common\Collections\Selectable``
-interface. That means you can build ``Doctrine\Common\Collections\Criteria``
-and pass them to the ``matching($criteria)`` method.
-
-See section `Filtering collections` of chapter :doc:`Working with Associations <working-with-associations>`
-
-By Eager Loading
-~~~~~~~~~~~~~~~~
-
-Whenever you query for an entity that has persistent associations
-and these associations are mapped as EAGER, they will automatically
-be loaded together with the entity being queried and is thus
-immediately available to your application.
-
-By Lazy Loading
-~~~~~~~~~~~~~~~
-
-Whenever you have a managed entity instance at hand, you can
-traverse and use any associations of that entity that are
-configured LAZY as if they were in-memory already. Doctrine will
-automatically load the associated objects on demand through the
-concept of lazy-loading.
-
-By DQL
-~~~~~~
-
-The most powerful and flexible method to query for persistent
-objects is the Doctrine Query Language, an object query language.
-DQL enables you to query for persistent objects in the language of
-objects. DQL understands classes, fields, inheritance and
-associations. DQL is syntactically very similar to the familiar SQL
-but *it is not SQL*.
-
-A DQL query is represented by an instance of the
-``Doctrine\ORM\Query`` class. You create a query using
-``EntityManager#createQuery($dql)``. Here is a simple example:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-
-    // All users with an age between 20 and 30 (inclusive).
-    $q = $em->createQuery("select u from MyDomain\Model\User u where u.age >= 20 and u.age <= 30");
-    $users = $q->getResult();
-
-Note that this query contains no knowledge about the relational
-schema, only about the object model. DQL supports positional as
-well as named parameters, many functions, (fetch) joins,
-aggregates, subqueries and much more. Detailed information about
-DQL and its syntax as well as the Doctrine class can be found in
-:doc:`the dedicated chapter <dql-doctrine-query-language>`.
-For programmatically building up queries based on conditions that
-are only known at runtime, Doctrine provides the special
-``Doctrine\ORM\QueryBuilder`` class. While this a powerful tool,
-it also brings more complexity to your code compared to plain DQL,
-so you should only use it when you need it. More information on
-constructing queries with a QueryBuilder can be found
-:doc:`in Query Builder chapter <query-builder>`.
-
-By Native Queries
-~~~~~~~~~~~~~~~~~
-
-As an alternative to DQL or as a fallback for special SQL
-statements native queries can be used. Native queries are built by
-using a hand-crafted SQL query and a ResultSetMapping that
-describes how the SQL result set should be transformed by Doctrine.
-More information about native queries can be found in
-:doc:`the dedicated chapter <native-sql>`.
-
-Custom Repositories
-~~~~~~~~~~~~~~~~~~~
-
-By default the EntityManager returns a default implementation of
-``Doctrine\ORM\EntityRepository`` when you call
-``EntityManager#getRepository($entityClass)``. You can overwrite
-this behaviour by specifying the class name of your own Entity
-Repository in the Annotation, XML or YAML metadata. In large
-applications that require lots of specialized DQL queries using a
-custom repository is one recommended way of grouping these queries
-in a central location.
-
-.. code-block:: php
-
-    <?php
-    namespace MyDomain\Model;
-
-    use Doctrine\ORM\EntityRepository;
-    use Doctrine\ORM\Mapping as ORM;
-
-    /**
-     * @ORM\Entity(repositoryClass="MyDomain\Model\UserRepository")
-     */
-    class User
-    {
-
-    }
-
-    class UserRepository extends EntityRepository
-    {
-        public function getAllAdminUsers()
-        {
-            return $this->_em->createQuery('SELECT u FROM MyDomain\Model\User u WHERE u.status = "admin"')
-                             ->getResult();
-        }
-    }
-
-You can access your repository now by calling:
-
-.. code-block:: php
-
-    <?php
-    // $em instanceof EntityManager
-
-    $admins = $em->getRepository('MyDomain\Model\User')->getAllAdminUsers();

-XML Mapping
-===========
-
-The XML mapping driver enables you to provide the ORM metadata in
-form of XML documents.
-
-The XML driver is backed by an XML Schema document that describes
-the structure of a mapping document. The most recent version of the
-XML Schema document is available online at
-`https://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd <https://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd>`_.
-The most convenient way to work with
-XML mapping files is to use an IDE/editor that can provide
-code-completion based on such an XML Schema document. The following
-is an outline of a XML mapping document with the proper xmlns/xsi
-setup for the latest code in trunk.
-
-.. code-block:: xml
-
-    <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
-          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-          xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
-                              https://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
-
-        ...
-
-    </doctrine-mapping>
-
-The XML mapping document of a class is loaded on-demand the first
-time it is requested and subsequently stored in the metadata cache.
-In order to work, this requires certain conventions:
-
-
--  Each entity/mapped superclass must get its own dedicated XML
-   mapping document.
--  The name of the mapping document must consist of the fully
-   qualified name of the class, where namespace separators are
-   replaced by dots (.). For example an Entity with the fully
-   qualified class-name "MyProject" would require a mapping file
-   "MyProject.Entities.User.dcm.xml" unless the extension is changed.
--  All mapping documents should get the extension ".dcm.xml" to
-   identify it as a Doctrine mapping file. This is more of a
-   convention and you are not forced to do this. You can change the
-   file extension easily enough.
-
-.. code-block:: php
-
-    <?php
-    $driver->setFileExtension('.xml');
-
-It is recommended to put all XML mapping documents in a single
-folder but you can spread the documents over several folders if you
-want to. In order to tell the XmlDriver where to look for your
-mapping documents, supply an array of paths as the first argument
-of the constructor, like this:
-
-.. code-block:: php
-
-    <?php
-    $config = new \Doctrine\ORM\Configuration();
-    $driver = new \Doctrine\ORM\Mapping\Driver\XmlDriver(array('/path/to/files1', '/path/to/files2'));
-    $config->setMetadataDriverImpl($driver);
-
-.. warning::
-
-    Note that Doctrine ORM does not modify any settings for ``libxml``,
-    therefore, external XML entities may or may not be enabled or
-    configured correctly.
-    XML mappings are not XXE/XEE attack vectors since they are not
-    related with user input, but it is recommended that you do not
-    use external XML entities in your mapping files to avoid running
-    into unexpected behaviour.
-
-Simplified XML Driver
-~~~~~~~~~~~~~~~~~~~~~
-
-The Symfony project sponsored a driver that simplifies usage of the XML Driver.
-The changes between the original driver are:
-
-1. File Extension is .orm.xml
-2. Filenames are shortened, "MyProject\Entities\User" will become User.orm.xml
-3. You can add a global file and add multiple entities in this file.
-
-Configuration of this client works a little bit different:
-
-.. code-block:: php
-
-    <?php
-    $namespaces = array(
-        '/path/to/files1' => 'MyProject\Entities',
-        '/path/to/files2' => 'OtherProject\Entities'
-    );
-    $driver = new \Doctrine\ORM\Mapping\Driver\SimplifiedXmlDriver($namespaces);
-    $driver->setGlobalBasename('global'); // global.orm.xml
-
-Example

-
-    </doctrine-mapping>
-
-Be aware that class-names specified in the XML files should be
-fully qualified.
-
-XML-Element Reference
----------------------
-
-The XML-Element reference explains all the tags and attributes that
-the Doctrine Mapping XSD Schema defines. You should read the
-Basic-, Association- and Inheritance Mapping chapters to understand
-what each of this definitions means in detail.
-
-Defining an Entity
-~~~~~~~~~~~~~~~~~~
-
-Each XML Mapping File contains the definition of one entity,
-specified as the ``<entity />`` element as a direct child of the
-``<doctrine-mapping />`` element:
-
-.. code-block:: xml
-
-    <doctrine-mapping>
-        <entity name="MyProject\User" table="cms_users" schema="schema_name" repository-class="MyProject\UserRepository">
-            <!-- definition here -->
-        </entity>
-    </doctrine-mapping>
-
-Required attributes:
-
-
--  name - The fully qualified class-name of the entity.
-
-Optional attributes:
-
-
--  **table** - The Table-Name to be used for this entity. Otherwise the
-   Unqualified Class-Name is used by default.
--  **repository-class** - The fully qualified class-name of an
-   alternative ``Doctrine\ORM\EntityRepository`` implementation to be
-   used with this entity.
--  **inheritance-type** - The type of inheritance, defaults to none. A
-   more detailed description follows in the
-   *Defining Inheritance Mappings* section.
--  **read-only** - Specifies that this entity is marked as read only and not
-   considered for change-tracking. Entities of this type can be persisted
-   and removed though.
--  **schema** - The schema the table lies in, for platforms that support schemas
-
-Defining Fields
-~~~~~~~~~~~~~~~
-
-Each entity class can contain zero to infinite fields that are
-managed by Doctrine. You can define them using the ``<field />``
-element as a children to the ``<entity />`` element. The field
-element is only used for primitive types that are not the ID of the
-entity. For the ID mapping you have to use the ``<id />`` element.
-
-.. code-block:: xml
-
-    <entity name="MyProject\User">
-
-        <field name="name" type="string" length="50" />
-        <field name="username" type="string" unique="true" />
-        <field name="age" type="integer" nullable="true" />
-        <field name="isActive" column="is_active" type="boolean" />
-        <field name="weight" type="decimal" scale="5" precision="2" />
-        <field name="login_count" type="integer" nullable="false">
-            <options>
-                <option name="comment">The number of times the user has logged in.</option>
-                <option name="default">0</option>
-            </options>
-        </field>
-    </entity>
-
-Required attributes:
-
-
--  name - The name of the Property/Field on the given Entity PHP
-   class.
-
-Optional attributes:
-
-
--  type - The ``Doctrine\DBAL\Types\Type`` name, defaults to
-   "string"
--  column - Name of the column in the database, defaults to the
-   field name.
--  length - The length of the given type, for use with strings
-   only.
--  unique - Should this field contain a unique value across the
-   table? Defaults to false.
--  nullable - Should this field allow NULL as a value? Defaults to
-   false.
--  version - Should this field be used for optimistic locking? Only
-   works on fields with type integer or datetime.
--  scale - Scale of a decimal type.
--  precision - Precision of a decimal type.
--  options - Array of additional options:
-
-   -  default - The default value to set for the column if no value
-      is supplied.
-   -  unsigned - Boolean value to determine if the column should
-      be capable of representing only non-negative integers
-      (applies only for integer column and might not be supported by
-      all vendors).
-   -  fixed - Boolean value to determine if the specified length of
-      a string column should be fixed or varying (applies only for
-      string/binary column and might not be supported by all vendors).
-   -  comment - The comment of the column in the schema (might not
-      be supported by all vendors).
-   -  customSchemaOptions - Array of additional schema options
-      which are mostly vendor specific.
--  column-definition - Optional alternative SQL representation for
-   this column. This definition begin after the field-name and has to
-   specify the complete column definition. Using this feature will
-   turn this field dirty for Schema-Tool update commands at all
-   times.
-
-.. note::
-
-    For more detailed information on each attribute, please refer to
-    the DBAL ``Schema-Representation`` documentation.
-
-Defining Identity and Generator Strategies
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-An entity has to have at least one ``<id />`` element. For
-composite keys you can specify more than one id-element, however
-surrogate keys are recommended for use with Doctrine ORM. The Id
-field allows to define properties of the identifier and allows a
-subset of the ``<field />`` element attributes:
-
-.. code-block:: xml
-
-    <entity name="MyProject\User">
-        <id name="id" type="integer" column="user_id" />
-    </entity>
-
-Required attributes:
-
-
--  name - The name of the Property/Field on the given Entity PHP
-   class.
--  type - The ``Doctrine\DBAL\Types\Type`` name, preferably
-   "string" or "integer".
-
-Optional attributes:
-
-
--  column - Name of the column in the database, defaults to the
-   field name.
-
-Using the simplified definition above Doctrine will use no
-identifier strategy for this entity. That means you have to
-manually set the identifier before calling
-``EntityManager#persist($entity)``. This is the so called
-``NONE`` strategy.
-
-If you want to switch the identifier generation strategy you have
-to nest a ``<generator />`` element inside the id-element. This of
-course only works for surrogate keys. For composite keys you always
-have to use the ``NONE`` strategy.
-
-.. code-block:: xml
-
-    <entity name="MyProject\User">
-        <id name="id" type="integer" column="user_id">
-            <generator strategy="AUTO" />
-        </id>
-    </entity>
-
-The following values are allowed for the ``<generator />`` strategy
-attribute:
-
-
--  AUTO - Automatic detection of the identifier strategy based on
-   the preferred solution of the database vendor.
--  IDENTITY - Use of a IDENTIFY strategy such as Auto-Increment IDs
-   available to Doctrine AFTER the INSERT statement has been executed.
--  SEQUENCE - Use of a database sequence to retrieve the
-   entity-ids. This is possible before the INSERT statement is
-   executed.
-
-If you are using the SEQUENCE strategy you can define an additional
-element to describe the sequence:
-
-.. code-block:: xml
-
-    <entity name="MyProject\User">
-        <id name="id" type="integer" column="user_id">
-            <generator strategy="SEQUENCE" />
-            <sequence-generator sequence-name="user_seq" allocation-size="5" initial-value="1" />
-        </id>
-    </entity>
-
-Required attributes for ``<sequence-generator />``:
-
-
--  sequence-name - The name of the sequence
-
-Optional attributes for ``<sequence-generator />``:
-
-
--  allocation-size - By how much steps should the sequence be
-   incremented when a value is retrieved. Defaults to 1
--  initial-value - What should the initial value of the sequence
-   be.
-
-    **NOTE**
-
-    If you want to implement a cross-vendor compatible application you
-    have to specify and additionally define the <sequence-generator />
-    element, if Doctrine chooses the sequence strategy for a
-    platform.
-
-
-Defining a Mapped Superclass
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Sometimes you want to define a class that multiple entities inherit
-from, which itself is not an entity however. The chapter on
-*Inheritance Mapping* describes a Mapped Superclass in detail. You
-can define it in XML using the ``<mapped-superclass />`` tag.
-
-.. code-block:: xml
-
-    <doctrine-mapping>
-        <mapped-superclass name="MyProject\BaseClass">
-            <field name="created" type="datetime" />
-            <field name="updated" type="datetime" />
-        </mapped-superclass>
-    </doctrine-mapping>
-
-Required attributes:
-
-
--  name - Class name of the mapped superclass.
-
-You can nest any number of ``<field />`` and unidirectional
-``<many-to-one />`` or ``<one-to-one />`` associations inside a
-mapped superclass.
-
-Defining Inheritance Mappings
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are currently two inheritance persistence strategies that you
-can choose from when defining entities that inherit from each
-other. Single Table inheritance saves the fields of the complete
-inheritance hierarchy in a single table, joined table inheritance
-creates a table for each entity combining the fields using join
-conditions.
-
-You can specify the inheritance type in the ``<entity />`` element
-and then use the ``<discriminator-column />`` and
-``<discriminator-mapping />`` attributes.
-
-.. code-block:: xml
-
-    <entity name="MyProject\Animal" inheritance-type="JOINED">
-        <discriminator-column name="discr" type="string" />
-        <discriminator-map>
-            <discriminator-mapping value="cat" class="MyProject\Cat" />
-            <discriminator-mapping value="dog" class="MyProject\Dog" />
-            <discriminator-mapping value="mouse" class="MyProject\Mouse" />
-        </discriminator-map>
-    </entity>
-
-The allowed values for inheritance-type attribute are ``JOINED`` or
-``SINGLE_TABLE``.
-
-.. note::
-
-    All inheritance related definitions have to be defined on the root
-    entity of the hierarchy.
-
-
-Defining Lifecycle Callbacks
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can define the lifecycle callback methods on your entities
-using the ``<lifecycle-callbacks />`` element:
-
-.. code-block:: xml
-
-    <entity name="Doctrine\Tests\ORM\Mapping\User" table="cms_users">
-
-        <lifecycle-callbacks>
-            <lifecycle-callback type="prePersist" method="onPrePersist" />
-        </lifecycle-callbacks>
-    </entity>
-
-Defining One-To-One Relations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can define One-To-One Relations/Associations using the
-``<one-to-one />`` element. The required and optional attributes
-depend on the associations being on the inverse or owning side.
-
-For the inverse side the mapping is as simple as:
-
-.. code-block:: xml
-
-    <entity class="MyProject\User">
-        <one-to-one field="address" target-entity="Address" mapped-by="user" />
-    </entity>
-
-Required attributes for inverse One-To-One:
-
-
--  field - Name of the property/field on the entity's PHP class.
--  target-entity - Name of the entity associated entity class. If
-   this is not qualified the namespace of the current class is
-   prepended. *IMPORTANT:* No leading backslash!
--  mapped-by - Name of the field on the owning side (here Address
-   entity) that contains the owning side association.
-
-For the owning side this mapping would look like:
-
-.. code-block:: xml
-
-    <entity class="MyProject\Address">
-        <one-to-one field="user" target-entity="User" inversed-by="address" />
-    </entity>
-
-Required attributes for owning One-to-One:
-
-
--  field - Name of the property/field on the entity's PHP class.
--  target-entity - Name of the entity associated entity class. If
-   this is not qualified the namespace of the current class is
-   prepended. *IMPORTANT:* No leading backslash!
-
-Optional attributes for owning One-to-One:
-
-
--  inversed-by - If the association is bidirectional the
-   inversed-by attribute has to be specified with the name of the
-   field on the inverse entity that contains the back-reference.
--  orphan-removal - If true, the inverse side entity is always
-   deleted when the owning side entity is. Defaults to false.
--  fetch - Either LAZY or EAGER, defaults to LAZY. This attribute
-   makes only sense on the owning side, the inverse side *ALWAYS* has
-   to use the ``FETCH`` strategy.
-
-The definition for the owning side relies on a bunch of mapping
-defaults for the join column names. Without the nested
-``<join-column />`` element Doctrine assumes to foreign key to be
-called ``user_id`` on the Address Entities table. This is because
-the ``MyProject\Address`` entity is the owning side of this
-association, which means it contains the foreign key.
-
-The completed explicitly defined mapping is:
-
-.. code-block:: xml
-
-    <entity class="MyProject\Address">
-        <one-to-one field="user" target-entity="User" inversed-by="address">
-            <join-column name="user_id" referenced-column-name="id" />
-        </one-to-one>
-    </entity>
-
-Defining Many-To-One Associations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The many-to-one association is *ALWAYS* the owning side of any
-bidirectional association. This simplifies the mapping compared to
-the one-to-one case. The minimal mapping for this association looks
-like:
-
-.. code-block:: xml
-
-    <entity class="MyProject\Article">
-        <many-to-one field="author" target-entity="User" />
-    </entity>
-
-Required attributes:
-
-
--  field - Name of the property/field on the entity's PHP class.
--  target-entity - Name of the entity associated entity class. If
-   this is not qualified the namespace of the current class is
-   prepended. *IMPORTANT:* No leading backslash!
-
-Optional attributes:
-
-
--  inversed-by - If the association is bidirectional the
-   inversed-by attribute has to be specified with the name of the
-   field on the inverse entity that contains the back-reference.
--  orphan-removal - If true the entity on the inverse side is
-   always deleted when the owning side entity is and it is not
-   connected to any other owning side entity anymore. Defaults to
-   false.
--  fetch - Either LAZY or EAGER, defaults to LAZY.
-
-This definition relies on a bunch of mapping defaults with regards
-to the naming of the join-column/foreign key. The explicitly
-defined mapping includes a ``<join-column />`` tag nested inside
-the many-to-one association tag:
-
-.. code-block:: xml
-
-    <entity class="MyProject\Article">
-        <many-to-one field="author" target-entity="User">
-            <join-column name="author_id" referenced-column-name="id" />
-        </many-to-one>
-    </entity>
-
-The join-column attribute ``name`` specifies the column name of the
-foreign key and the ``referenced-column-name`` attribute specifies
-the name of the primary key column on the User entity.
-
-Defining One-To-Many Associations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The one-to-many association is *ALWAYS* the inverse side of any
-association. There exists no such thing as a uni-directional
-one-to-many association, which means this association only ever
-exists for bi-directional associations.
-
-.. code-block:: xml
-
-    <entity class="MyProject\User">
-        <one-to-many field="phonenumbers" target-entity="Phonenumber" mapped-by="user" />
-    </entity>
-
-Required attributes:
-
-
--  field - Name of the property/field on the entity's PHP class.
--  target-entity - Name of the entity associated entity class. If
-   this is not qualified the namespace of the current class is
-   prepended. *IMPORTANT:* No leading backslash!
--  mapped-by - Name of the field on the owning side (here
-   Phonenumber entity) that contains the owning side association.
-
-Optional attributes:
-
-
--  fetch - Either LAZY, EXTRA_LAZY or EAGER, defaults to LAZY.
--  index-by: Index the collection by a field on the target entity.
-
-Defining Many-To-Many Associations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-From all the associations the many-to-many has the most complex
-definition. When you rely on the mapping defaults you can omit many
-definitions and rely on their implicit values.
-
-.. code-block:: xml
-
-    <entity class="MyProject\User">
-        <many-to-many field="groups" target-entity="Group" />
-    </entity>
-
-Required attributes:
-
-
--  field - Name of the property/field on the entity's PHP class.
--  target-entity - Name of the entity associated entity class. If
-   this is not qualified the namespace of the current class is
-   prepended. *IMPORTANT:* No leading backslash!
-
-Optional attributes:
-
-
--  mapped-by - Name of the field on the owning side that contains
-   the owning side association if the defined many-to-many association
-   is on the inverse side.
--  inversed-by - If the association is bidirectional the
-   inversed-by attribute has to be specified with the name of the
-   field on the inverse entity that contains the back-reference.
--  fetch - Either LAZY, EXTRA_LAZY or EAGER, defaults to LAZY.
--  index-by: Index the collection by a field on the target entity.
-
-The mapping defaults would lead to a join-table with the name
-"User\_Group" being created that contains two columns "user\_id"
-and "group\_id". The explicit definition of this mapping would be:
-
-.. code-block:: xml
-
-    <entity class="MyProject\User">
-        <many-to-many field="groups" target-entity="Group">
-            <join-table name="cms_users_groups">
-                <join-columns>
-                    <join-column name="user_id" referenced-column-name="id"/>
-                </join-columns>
-                <inverse-join-columns>
-                    <join-column name="group_id" referenced-column-name="id"/>
-                </inverse-join-columns>
-            </join-table>
-        </many-to-many>
-    </entity>
-
-Here both the ``<join-columns>`` and ``<inverse-join-columns>``
-tags are necessary to tell Doctrine for which side the specified
-join-columns apply. These are nested inside a ``<join-table />``
-attribute which allows to specify the table name of the
-many-to-many join-table.
-
-Cascade Element
-~~~~~~~~~~~~~~~
-
-Doctrine allows cascading of several UnitOfWork operations to
-related entities. You can specify the cascade operations in the
-``<cascade />`` element inside any of the association mapping
-tags.
-
-.. code-block:: xml
-
-    <entity class="MyProject\User">
-        <many-to-many field="groups" target-entity="Group">
-            <cascade>
-                <cascade-all/>
-            </cascade>
-        </many-to-many>
-    </entity>
-
-Besides ``<cascade-all />`` the following operations can be
-specified by their respective tags:
-
-
--  ``<cascade-persist />``
--  ``<cascade-merge />``
--  ``<cascade-remove />``
--  ``<cascade-refresh />``
-
-Join Column Element
-~~~~~~~~~~~~~~~~~~~
-
-In any explicitly defined association mapping you will need the
-``<join-column />`` tag. It defines how the foreign key and primary
-key names are called that are used for joining two entities.
-
-Required attributes:
-
-
--  name - The column name of the foreign key.
--  referenced-column-name - The column name of the associated
-   entities primary key
-
-Optional attributes:
-
-
--  unique - If the join column should contain a UNIQUE constraint.
-   This makes sense for Many-To-Many join-columns only to simulate a
-   one-to-many unidirectional using a join-table.
--  nullable - should the join column be nullable, defaults to true.
--  on-delete - Foreign Key Cascade action to perform when entity is
-   deleted, defaults to NO ACTION/RESTRICT but can be set to
-   "CASCADE".
-
-Defining Order of To-Many Associations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can require one-to-many or many-to-many associations to be
-retrieved using an additional ``ORDER BY``.
-
-.. code-block:: xml
-
-    <entity class="MyProject\User">
-        <many-to-many field="groups" target-entity="Group">
-            <order-by>
-                <order-by-field name="name" direction="ASC" />
-            </order-by>
-        </many-to-many>
-    </entity>
-
-Defining Indexes or Unique Constraints
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To define additional indexes or unique constraints on the entities
-table you can use the ``<indexes />`` and
-``<unique-constraints />`` elements:
-
-.. code-block:: xml
-
-    <entity name="Doctrine\Tests\ORM\Mapping\User" table="cms_users">
-
-        <indexes>
-            <index name="name_idx" columns="name"/>
-            <index columns="user_email"/>
-        </indexes>
-
-        <unique-constraints>
-            <unique-constraint columns="name,user_email" name="search_idx" />
-        </unique-constraints>
-    </entity>
-
-You have to specify the column and not the entity-class field names
-in the index and unique-constraint definitions.
-
-Derived Entities ID syntax
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If the primary key of an entity contains a foreign key to another entity we speak of a derived
-entity relationship. You can define this in XML with the "association-key" attribute in the ``<id>`` tag.
-
-.. code-block:: xml
-
-    <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
-          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-          xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
-                              https://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
-
-         <entity name="Application\Model\ArticleAttribute">
-            <id name="article" association-key="true" />
-            <id name="attribute" type="string" />
-
-            <field name="value" type="string" />
-
-            <many-to-one field="article" target-entity="Article" inversed-by="attributes" />
-         </entity>

-    </doctrine-mapping>

-YAML Mapping
-============
-
-.. note::
-    The YAML driver is deprecated and will be removed in version 3.0.
-    It is strongly recommended to switch to one of the other mappings.
-
-The YAML mapping driver enables you to provide the ORM metadata in
-form of YAML documents.
-
-The YAML mapping document of a class is loaded on-demand the first
-time it is requested and subsequently stored in the metadata cache.
-In order to work, this requires certain conventions:
-
-
--  Each entity/mapped superclass must get its own dedicated YAML
-   mapping document.
--  The name of the mapping document must consist of the fully
-   qualified name of the class, where namespace separators are
-   replaced by dots (.).
--  All mapping documents should get the extension ".dcm.yml" to
-   identify it as a Doctrine mapping file. This is more of a
-   convention and you are not forced to do this. You can change the
-   file extension easily enough.
-
-.. code-block:: php
-
-    <?php
-    $driver->setFileExtension('.yml');
-
-It is recommended to put all YAML mapping documents in a single
-folder but you can spread the documents over several folders if you
-want to. In order to tell the YamlDriver where to look for your
-mapping documents, supply an array of paths as the first argument
-of the constructor, like this:
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Mapping\Driver\YamlDriver;
-
-    // $config instanceof Doctrine\ORM\Configuration
-    $driver = new YamlDriver(array('/path/to/files'));
-    $config->setMetadataDriverImpl($driver);
-
-Simplified YAML Driver
-~~~~~~~~~~~~~~~~~~~~~~
-
-The Symfony project sponsored a driver that simplifies usage of the YAML Driver.
-The changes between the original driver are:
-
-- File Extension is .orm.yml
-- Filenames are shortened, "MyProject\\Entities\\User" will become User.orm.yml
-- You can add a global file and add multiple entities in this file.
-
-Configuration of this client works a little bit different:
-
-.. code-block:: php
-
-    <?php
-    $namespaces = array(
-        '/path/to/files1' => 'MyProject\Entities',
-        '/path/to/files2' => 'OtherProject\Entities'
-    );
-    $driver = new \Doctrine\ORM\Mapping\Driver\SimplifiedYamlDriver($namespaces);
-    $driver->setGlobalBasename('global'); // global.orm.yml
-
-Example
--------
-
-As a quick start, here is a small example document that makes use
-of several common elements:
-
-.. code-block:: yaml
-
-    # Doctrine.Tests.ORM.Mapping.User.dcm.yml
-    Doctrine\Tests\ORM\Mapping\User:
-      type: entity
-      repositoryClass: Doctrine\Tests\ORM\Mapping\UserRepository
-      table: cms_users
-      schema: schema_name # The schema the table lies in, for platforms that support schemas (Optional, >= 2.5)
-      readOnly: true
-      indexes:
-        name_index:
-          columns: [ name ]
-      id:
-        id:
-          type: integer
-          generator:
-            strategy: AUTO
-      fields:
-        name:
-          type: string
-          length: 50
-        email:
-          type: string
-          length: 32
-          column: user_email
-          unique: true
-          options:
-            fixed: true
-            comment: User's email address
-        loginCount:
-          type: integer
-          column: login_count
-          nullable: false
-          options:
-            unsigned: true
-            default: 0
-      oneToOne:
-        address:
-          targetEntity: Address
-          joinColumn:
-            name: address_id
-            referencedColumnName: id
-            onDelete: CASCADE
-      oneToMany:
-        phonenumbers:
-          targetEntity: Phonenumber
-          mappedBy: user
-          cascade: ["persist", "merge"]
-      manyToMany:
-        groups:
-          targetEntity: Group
-          joinTable:
-            name: cms_users_groups
-            joinColumns:
-              user_id:
-                referencedColumnName: id
-            inverseJoinColumns:
-              group_id:
-                referencedColumnName: id
-      lifecycleCallbacks:
-        prePersist: [ doStuffOnPrePersist, doOtherStuffOnPrePersistToo ]
-        postPersist: [ doStuffOnPostPersist ]
-
-Be aware that class-names specified in the YAML files should be
-fully qualified.

-Unique Constraints
-------------------
-
-It is possible to define unique constraints by the following declaration:
-
-.. code-block:: yaml
-
-    # ECommerceProduct.orm.yml
-    ECommerceProduct:
-      type: entity
-      fields:
-        # definition of some fields
-      uniqueConstraints:
-        search_idx:
-          columns: [ name, email ]

-Composite and Foreign Keys as Primary Key
-=========================================
-
-Doctrine ORM supports composite primary keys natively. Composite keys are a very powerful relational database concept
-and we took good care to make sure Doctrine ORM supports as many of the composite primary key use-cases.
-For Doctrine ORM composite keys of primitive data-types are supported, even foreign keys as
-primary keys are supported.
-
-This tutorial shows how the semantics of composite primary keys work and how they map to the database.
-
-General Considerations
-~~~~~~~~~~~~~~~~~~~~~~
-
-Every entity with a composite key cannot use an id generator other than "NONE". That means
-the ID fields have to have their values set before you call ``EntityManager#persist($entity)``.
-
-Primitive Types only
-~~~~~~~~~~~~~~~~~~~~
-
-You can have composite keys as long as they only consist of the primitive types
-``integer`` and ``string``. Suppose you want to create a database of cars and use the model-name
-and year of production as primary keys:
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        namespace VehicleCatalogue\Model;
-
-        /**
-         * @Entity
-         */
-        class Car
-        {
-            /** @Id @Column(type="string") */
-            private $name;
-            /** @Id @Column(type="integer") */
-            private $year;
-
-            public function __construct($name, $year)
-            {
-                $this->name = $name;
-                $this->year = $year;
-            }
-
-            public function getModelName()
-            {
-                return $this->name;
-            }
-
-            public function getYearOfProduction()
-            {
-                return $this->year;
-            }
-        }
-
-    .. code-block:: xml
-
-        <?xml version="1.0" encoding="UTF-8"?>
-        <doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
-              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-              xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
-                                  https://www.doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
-
-            <entity name="VehicleCatalogue\Model\Car">
-                <id field="name" type="string" />
-                <id field="year" type="integer" />
-            </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        VehicleCatalogue\Model\Car:
-          type: entity
-          id:
-            name:
-              type: string
-            year:
-              type: integer
-
-Now you can use this entity:
-
-.. code-block:: php
-
-    <?php
-    namespace VehicleCatalogue\Model;
-
-    // $em is the EntityManager
-
-    $car = new Car("Audi A8", 2010);
-    $em->persist($car);
-    $em->flush();
-
-And for querying you can use arrays to both DQL and EntityRepositories:
-
-.. code-block:: php
-
-    <?php
-    namespace VehicleCatalogue\Model;
-
-    // $em is the EntityManager
-    $audi = $em->find("VehicleCatalogue\Model\Car", array("name" => "Audi A8", "year" => 2010));
-
-    $dql = "SELECT c FROM VehicleCatalogue\Model\Car c WHERE c.id = ?1";
-    $audi = $em->createQuery($dql)
-               ->setParameter(1, array("name" => "Audi A8", "year" => 2010))
-               ->getSingleResult();
-
-You can also use this entity in associations. Doctrine will then generate two foreign keys one for ``name``
-and to ``year`` to the related entities.
-
-.. note::
-
-    This example shows how you can nicely solve the requirement for existing
-    values before ``EntityManager#persist()``: By adding them as mandatory values for the constructor.
-
-Identity through foreign Entities
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are tons of use-cases where the identity of an Entity should be determined by the entity
-of one or many parent entities.
-
--   Dynamic Attributes of an Entity (for example Article). Each Article has many
-    attributes with primary key "article_id" and "attribute_name".
--   Address object of a Person, the primary key of the address is "user_id". This is not a case of a composite primary
-    key, but the identity is derived through a foreign entity and a foreign key.
--   Join Tables with metadata can be modelled as Entity, for example connections between two articles
-    with a little description and a score.
-
-The semantics of mapping identity through foreign entities are easy:
-
--   Only allowed on Many-To-One or One-To-One associations.
--   Plug an ``@Id`` annotation onto every association.
--   Set an attribute ``association-key`` with the field name of the association in XML.
--   Set a key ``associationKey:`` with the field name of the association in YAML.
-
-Use-Case 1: Dynamic Attributes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-Use-Case 2: Simple Derived Identity
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Sometimes you have the requirement that two objects are related by a One-To-One association
-and that the dependent class should re-use the primary key of the class it depends on.
-One good example for this is a user-address relationship:

-        }
-
-        /**

-         */
-        class Address
-        {
-            /** @Id @OneToOne(targetEntity="User") */
-            private $user;
-        }

-          oneToOne:
-            user:
-              targetEntity: User
-
-
-Use-Case 3: Join-Table with Metadata
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In the classic order product shop example there is the concept of the order item
-which contains references to order and product and additional data such as the amount
-of products purchased and maybe even the current price.
-
-.. code-block:: php

-    use Doctrine\Common\Collections\ArrayCollection;

-
-        /** @ManyToOne(targetEntity="Customer") */

-            $this->offeredPrice = $product->getCurrentPrice();
-        }
-    }

-Performance Considerations
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Using composite keys always comes with a performance hit compared to using entities with
-a simple surrogate key. This performance impact is mostly due to additional PHP code that is
-necessary to handle this kind of keys, most notably when using derived identifiers.
-
-On the SQL side there is not much overhead as no additional or unexpected queries have to be
-executed to manage entities with derived foreign keys.

-Separating Concerns using Embeddables
--------------------------------------
-
-Embeddables are classes which are not entities themselves, but are embedded
-in entities and can also be queried in DQL. You'll mostly want to use them
-to reduce duplication or separating concerns. Value objects such as date range
-or address are the primary use case for this feature. 
-
-.. note::
-
-    Embeddables can only contain properties with basic ``@Column`` mapping.
-
-For the purposes of this tutorial, we will assume that you have a ``User``
-class in your application and you would like to store an address in
-the ``User`` class. We will model the ``Address`` class as an embeddable
-instead of simply adding the respective columns to the ``User`` class.
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-
-        /** @Entity */
-        class User
-        {
-            /** @Embedded(class = "Address") */
-            private $address;
-        }
-
-        /** @Embeddable */
-        class Address
-        {
-            /** @Column(type = "string") */
-            private $street;
-
-            /** @Column(type = "string") */
-            private $postalCode;
-
-            /** @Column(type = "string") */
-            private $city;
-
-            /** @Column(type = "string") */
-            private $country;
-        }

-                <embedded name="address" class="Address" />

-
-            <embeddable name="Address">

-            city: { type: string }
-            country: { type: string }
-
-In terms of your database schema, Doctrine will automatically inline all
-columns from the ``Address`` class into the table of the ``User`` class,
-just as if you had declared them directly there.
-
-Initializing embeddables
-------------------------
-
-In case all fields in the embeddable are ``nullable``, you might want
-to initialize the embeddable, to avoid getting a null value instead of
-the embedded object.
-
-.. code-block:: php
-
-    public function __construct()
-    {
-        $this->address = new Address();
-    }
-
-Column Prefixing
-----------------
-
-By default, Doctrine names your columns by prefixing them, using the value
-object name.
-
-Following the example above, your columns would be named as ``address_street``,
-``address_postalCode``...
-
-You can change this behaviour to meet your needs by changing the
-``columnPrefix`` attribute in the ``@Embedded`` notation.
-
-The following example shows you how to set your prefix to ``myPrefix_``:
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-
-        /** @Entity */
-        class User
-        {
-            /** @Embedded(class = "Address", columnPrefix = "myPrefix_") */
-            private $address;
-        }
-
-    .. code-block:: xml
-
-        <entity name="User">
-            <embedded name="address" class="Address" column-prefix="myPrefix_" />
-        </entity>
-
-    .. code-block:: yaml
-
-        User:
-          type: entity
-          embedded:
-            address:
-              class: Address
-              columnPrefix: myPrefix_
-
-To have Doctrine drop the prefix and use the value object's property name
-directly, set ``columnPrefix=false`` (``use-column-prefix="false"`` for XML):
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-
-        /** @Entity */
-        class User
-        {
-            /** @Embedded(class = "Address", columnPrefix = false) */
-            private $address;
-        }
-
-    .. code-block:: yaml
-
-        User:
-          type: entity
-          embedded:
-            address:
-              class: Address
-              columnPrefix: false
-
-    .. code-block:: xml
-
-        <entity name="User">
-            <embedded name="address" class="Address" use-column-prefix="false" />
-        </entity>
-
-
-DQL
----
-
-You can also use mapped fields of embedded classes in DQL queries, just
-as if they were declared in the ``User`` class:
-
-.. code-block:: sql
-
-    SELECT u FROM User u WHERE u.address.city = :myCity

-Extra Lazy Associations
-=======================
-
-.. versionadded:: 2.1
-
-In many cases associations between entities can get pretty large. Even in a simple scenario like a blog.
-where posts can be commented, you always have to assume that a post draws hundreds of comments.
-In Doctrine ORM if you accessed an association it would always get loaded completely into memory. This
-can lead to pretty serious performance problems, if your associations contain several hundreds or thousands
-of entities.
-
-Doctrine ORM includes a feature called **Extra Lazy** for associations. Associations
-are marked as **Lazy** by default, which means the whole collection object for an association is populated
-the first time its accessed. If you mark an association as extra lazy the following methods on collections
-can be called without triggering a full load of the collection:
-
--  ``Collection#contains($entity)``
--  ``Collection#containsKey($key)``
--  ``Collection#count()``
--  ``Collection#get($key)``
--  ``Collection#slice($offset, $length = null)``
-
-For each of the above methods the following semantics apply:
-
--  For each call, if the Collection is not yet loaded, issue a straight SELECT statement against the database.
--  For each call, if the collection is already loaded, fallback to the default functionality for lazy collections. No additional SELECT statements are executed.
-
-Additionally even with Doctrine ORM the following methods do not trigger the collection load:
-
--  ``Collection#add($entity)``
--  ``Collection#offsetSet($key, $entity)`` - ArrayAccess with no specific key ``$coll[] = $entity``, it does
-   not work when setting specific keys like ``$coll[0] = $entity``.
-
-With extra lazy collections you can now not only add entities to large collections but also paginate them
-easily using a combination of ``count`` and ``slice``.
-
-
-.. warning::
-
-   ``removeElement`` directly issued DELETE queries to the database from
-   version 2.4.0 to 2.7.0.  This circumvents the flush operation and might run
-   outside a transactional boundary if you don't create one yourself. We
-   consider this a critical bug in the assumptio of how the ORM works and
-   reverted ``removeElement`` EXTRA_LAZY behavior in 2.7.1.

-can specify the ``@OrderBy`` in the following way:
-
-.. configuration-block::
-
-    .. code-block:: php
-
-        <?php
-        /** @Entity **/
-        class User
-        {
-            // ...
-        
-            /**
-             * @ManyToMany(targetEntity="Group")
-             * @OrderBy({"name" = "ASC"})
-             **/
-            private $groups;
-        }

-                    <order-by>
-                        <order-by-field name="name" direction="ASC" />
-                    </order-by>
-                </many-to-many>
-            </entity>
-        </doctrine-mapping>
-
-    .. code-block:: yaml
-
-        User:
-          type: entity
-          manyToMany:
-            groups:
-              orderBy: { 'name': 'ASC' }
-              targetEntity: Group
-              joinTable:
-                name: users_groups
-                joinColumns:
-                  user_id:
-                    referencedColumnName: id
-                inverseJoinColumns:
-                  group_id:
-                    referencedColumnName: id
-
-The DQL Snippet in OrderBy is only allowed to consist of
-unqualified, unquoted field names and of an optional ASC/DESC
-positional statement. Multiple Fields are separated by a comma (,).
-The referenced field names have to exist on the ``targetEntity``
-class of the ``@ManyToMany`` or ``@OneToMany`` annotation.
-
-The semantics of this feature can be described as follows:
-
-
--  ``@OrderBy`` acts as an implicit ORDER BY clause for the given
-   fields, that is appended to all the explicitly given ORDER BY
-   items.
--  All collections of the ordered type are always retrieved in an
-   ordered fashion.
--  To keep the database impact low, these implicit ORDER BY items
-   are only added to a DQL Query if the collection is fetch joined in
-   the DQL query.
-
-Given our previously defined example, the following would not add
-ORDER BY, since g is not fetch joined:
-
-.. code-block:: sql
-
-    SELECT u FROM User u JOIN u.groups g WHERE SIZE(g) > 10
-
-However the following:
-
-.. code-block:: sql
-
-    SELECT u, g FROM User u JOIN u.groups g WHERE u.id = 10
-
-...would internally be rewritten to:
-
-.. code-block:: sql
-
-    SELECT u, g FROM User u JOIN u.groups g WHERE u.id = 10 ORDER BY g.name ASC
-
-You can reverse the order with an explicit DQL ORDER BY:
-
-.. code-block:: sql
-
-    SELECT u, g FROM User u JOIN u.groups g WHERE u.id = 10 ORDER BY g.name DESC
-
-...is internally rewritten to:
-
-.. code-block:: sql
-
-    SELECT u, g FROM User u JOIN u.groups g WHERE u.id = 10 ORDER BY g.name DESC, g.name ASC

-Override Field Association Mappings In Subclasses
--------------------------------------------------
-
-Sometimes there is a need to persist entities but override all or part of the
-mapping metadata. Sometimes also the mapping to override comes from entities
-using traits where the traits have mapping metadata.
-This tutorial explains how to override mapping metadata,
-i.e. attributes and associations metadata in particular. The example here shows
-the overriding of a class that uses a trait but is similar when extending a base
-class as shown at the end of this tutorial.
-
-Suppose we have a class ExampleEntityWithOverride. This class uses trait ExampleTrait:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * @Entity
-     *
-     * @AttributeOverrides({
-     *      @AttributeOverride(name="foo",
-     *          column=@Column(
-     *              name     = "foo_overridden",
-     *              type     = "integer",
-     *              length   = 140,
-     *              nullable = false,
-     *              unique   = false
-     *          )
-     *      )
-     * })
-     *
-     * @AssociationOverrides({
-     *      @AssociationOverride(name="bar",
-     *          joinColumns=@JoinColumn(
-     *              name="example_entity_overridden_bar_id", referencedColumnName="id"
-     *          )
-     *      )
-     * })
-     */
-    class ExampleEntityWithOverride
-    {
-        use ExampleTrait;
-    }
-
-    /**
-     * @Entity
-     */
-    class Bar
-    {
-        /** @Id @Column(type="string") */
-        private $id;
-    }
-
-The docblock is showing metadata override of the attribute and association type. It
-basically changes the names of the columns mapped for a property ``foo`` and for
-the association ``bar`` which relates to Bar class shown above. Here is the trait
-which has mapping metadata that is overridden by the annotation above:
-
-.. code-block:: php
-
-    <?php
-    /**
-     * Trait class
-     */
-    trait ExampleTrait
-    {
-        /** @Id @Column(type="string") */
-        private $id;
-
-        /**
-         * @Column(name="trait_foo", type="integer", length=100, nullable=true, unique=true)
-         */
-        protected $foo;
-
-        /**
-         * @OneToOne(targetEntity="Bar", cascade={"persist", "merge"})
-         * @JoinColumn(name="example_trait_bar_id", referencedColumnName="id")
-         */
-        protected $bar;
-    }
-
-The case for just extending a class would be just the same but:
-
-.. code-block:: php
-
-    <?php
-    class ExampleEntityWithOverride extends BaseEntityWithSomeMapping
-    {
-        // ...
-    }
-
-Overriding is also supported via XML and YAML (:ref:`examples <inheritence_mapping_overrides>`).

-Pagination
-==========
-
-Doctrine ORM ships with a Paginator for DQL queries. It
-has a very simple API and implements the SPL interfaces ``Countable`` and
-``IteratorAggregate``.
-
-.. code-block:: php
-
-    <?php
-    use Doctrine\ORM\Tools\Pagination\Paginator;
-
-    $dql = "SELECT p, c FROM BlogPost p JOIN p.comments c";
-    $query = $entityManager->createQuery($dql)
-                           ->setFirstResult(0)
-                           ->setMaxResults(100);
-
-    $paginator = new Paginator($query, $fetchJoinCollection = true);
-
-    $c = count($paginator);
-    foreach ($paginator as $post) {
-        echo $post->getHeadline() . "\n";
-    }
-
-Paginating Doctrine queries is not as simple as you might think in the
-beginning. If you have complex fetch-join scenarios with one-to-many or
-many-to-many associations using the "default" LIMIT functionality of database
-vendors is not sufficient to get the correct results.
-
-By default the pagination extension does the following steps to compute the
-correct result:
-
-- Perform a Count query using `DISTINCT` keyword.
-- Perform a Limit Subquery with `DISTINCT` to find all ids of the entity in from on the current page.
-- Perform a WHERE IN query to get all results for the current page.
-
-This behavior is only necessary if you actually fetch join a to-many
-collection. You can disable this behavior by setting the
-``$fetchJoinCollection`` flag to ``false``; in that case only 2 instead of the 3 queries
-described are executed. We hope to automate the detection for this in
-the future.

-Working with Indexed Associations
-=================================
-
-Doctrine ORM collections are modelled after PHPs native arrays. PHP arrays are an ordered hashmap, but in
-the first version of Doctrine keys retrieved from the database were always numerical unless ``INDEX BY``
-was used. You can index your collections by a value in the related entity.
-This is a first step towards full ordered hashmap support through the Doctrine ORM.
-The feature works like an implicit ``INDEX BY`` for the selected association but has several
-downsides also:
-
--  You have to manage both the key and field if you want to change the index by field value.
--  On each request the keys are regenerated from the field value, and not from the previous collection key.
--  Values of the Index-By keys are never considered during persistence. They only exist for accessing purposes.
--  Fields that are used for the index by feature **HAVE** to be unique in the database. The behavior for multiple entities
-   with the same index-by field value is undefined.
-
-As an example we will design a simple stock exchange list view. The domain consists of the entity ``Stock``
-and ``Market`` where each Stock has a symbol and is traded on a single market. Instead of having a numerical
-list of stocks traded on a market they will be indexed by their symbol, which is unique across all markets.
-
-Mapping Indexed Associations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can map indexed associations by adding:
-
-    * ``indexBy`` attribute to any ``@OneToMany`` or ``@ManyToMany`` annotation.
-    * ``index-by`` attribute to any ``<one-to-many />`` or ``<many-to-many />`` xml element.
-    * ``indexBy:`` key-value pair to any association defined in ``manyToMany:`` or ``oneToMany:`` YAML mapping files.
-
-The code and mappings for the Market entity looks like this:
-
-.. configuration-block::
-    .. code-block:: php
-
-        <?php
-        namespace Doctrine\Tests\Models\StockExchange;

-Inside the ``addStock()`` method you can see how we directly set the key of the association to the symbol,

-we pick a stock traded on the particular market by symbol. If this stock doesn't exist an exception is thrown.

-Querying indexed associations
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Now that we defined the stocks collection to be indexed by symbol, we can take a look at some code
-that makes use of the indexing.
-
-First we will populate our database with two example stocks traded on a single market:
-
-.. code-block:: php
-
-    <?php
-    // $em is the EntityManager
-
-    $market = new Market("Some Exchange");
-    $stock1 = new Stock("AAPL", $market);
-    $stock2 = new Stock("GOOG", $market);
-
-    $em->persist($market);
-    $em->persist($stock1);
-    $em->persist($stock2);
-    $em->flush();
-
-This code is not particular interesting since the indexing feature is not yet used. In a new request we could
-now query for the market:
-
-.. code-block:: php
-
-    <?php
-    // $em is the EntityManager
-    $marketId = 1;
-    $symbol = "AAPL";
-    
-    $market = $em->find("Doctrine\Tests\Models\StockExchange\Market", $marketId);
-
-    // Access the stocks by symbol now:
-    $stock = $market->getStock($symbol);
-
-    echo $stock->getSymbol(); // will print "AAPL"
-
-The implementation of ``Market::addStock()``, in combination with ``indexBy``, allows us to access the collection
-consistently by the Stock symbol. It does not matter if Stock is managed by Doctrine or not.
-
-The same applies to DQL queries: The ``indexBy`` configuration acts as implicit "INDEX BY" to a join association.
-
-.. code-block:: php
-
-    <?php
-    // $em is the EntityManager
-    $marketId = 1;
-    $symbol = "AAPL";
-
-    $dql = "SELECT m, s FROM Doctrine\Tests\Models\StockExchange\Market m JOIN m.stocks s WHERE m.id = ?1";
-    $market = $em->createQuery($dql)
-                 ->setParameter(1, $marketId)
-                 ->getSingleResult();
-
-    // Access the stocks by symbol now:
-    $stock = $market->getStock($symbol);
-
-    echo $stock->getSymbol(); // will print "AAPL"
-
-If you want to use ``INDEX BY`` explicitly on an indexed association you are free to do so. Additionally,
-indexed associations also work with the ``Collection::slice()`` functionality, even if the association's fetch mode is
-LAZY or EXTRA_LAZY.
-
-Outlook into the Future
-~~~~~~~~~~~~~~~~~~~~~~~
-
-For the inverse side of a many-to-many associations there will be a way to persist the keys and the order
-as a third and fourth parameter into the join table. This feature is discussed in `#2817 <https://github.com/doctrine/orm/issues/2817>`_
-This feature cannot be implemented for one-to-many associations, because they are never the owning side.
