All Implemented Interfaces:

Serializable

public class StandardPostModificationEvent
extends StandardModificationEvent

Event class that encapsulates all the event information for a standard collection event.

The information stored in this event is all that is available as parameters or return values. In addition, the size method is used on the collection. All objects used are the real objects from the method calls, not clones.

Commons Events 1.0
