Lanza una excepción al generador y reanuda su ejecución.
|
|
El comportamiento será el mismo que si la expresión &yield; actual fuera reemplazada con
|
|
una sentencia <literal>throw $exception</literal>.
|
|
</para>
|
|
<para>
|
|
Si el generador ya está cerrado al invocar a este método, la excepción
|
|
será lanzada en su lugar en el contexto del invocador.
