incorporate

public boolean incorporate(BasicEvent oldEvent)

Description copied from class: BasicEvent

Asks the event to incorporate the action described by another (older) event. This method has been created to reduce overhead; when many events are added to the event queue of an ELM, this allows to fuse two adjectant events. The idea is mainly based on the replaceEdit() method of the javax.swing.undo.UndoableEdit interface; a pendant of a symmetric addEdit() like method is not provided because it seems to be unnecessary.

Implementation notes : the oldEvent should generally only be incorporated if it refers to the same source object (getSource()) and has the same ID (getD()). the timestamp of the current event should not be modified.

Specified by:

incorporate in class BasicEvent

Parameters:

oldEvent - the most recent event in the queue which might be incorporated by this new event.

Returns:

true if this object was able to incorporate the older event. in this case the oldEvent is removed from the event queue. false states that the oldEvent was incompatible and should remain in the queue.
