Method Detail

isPrivate

public boolean isPrivate()

Description copied from class: DEvent

Some events are used only internally on the server and need not be broadcast to subscribers, proxy or otherwise. Such events can return true here and short-circuit the normal proxy event dispatch mechanism.

Overrides:

isPrivate in class DEvent

applyToObject

public boolean applyToObject(DObject target)
                      throws ObjectAccessException

Description copied from class: DEvent

Applies the attribute modifications represented by this event to the specified target object. This is called by the distributed object manager in the course of dispatching events and should not be called directly.

Specified by:

applyToObject in class DEvent

Returns:

true if the object manager should go on to notify the object's listeners of this event, false if the event should be treated silently and the listeners should not be notified.

Throws:

ObjectAccessException - thrown if there is any problem applying the event to the object (invalid attribute, etc.).
