Class EntityPersistenceEvent

  • Direct Known Subclasses:
    EntityDeleteEvent, EntityNewEvent, EntityUpdateEvent
    public class EntityPersistenceEvent
extends Object
    The base event object send out to reflect a persistence event on an entity (save, update, delete, etc.). Note: it is possible to directly access/retrieve the object which is being deleted or persisted. To update the object's state one should NOT call setters directly on that object. Instead use the setCurrentState(Property, Object) method.
