/**
 * Annotation to mark a method to be executed after a call to {@link EntityManager#persist(Object)} when flushing
 * the creatable entity view containing this method via {@link EntityViewManager#save(EntityManager, Object)}.
 * A method annotated with @PostPersist may optionally have the following parameters
 * 
 *     An {@link EntityViewManager}
 *     An {@link EntityManager}
 *     The entity object. The entity type of the entity view and all super types are allowed.
 * 
 * There may only be one method in a class annotated with @PostPersist and it must return void.
 * Super type methods annotated with @PostPersist are ignored if an entity view defines a @PostPersist method.
