All Implemented Interfaces:

UserListener

public class ListenerList

extends java.lang.Object

implements UserListener

Implements a abstract list of event listeners. Each listener has a user assigned. When the user goes offline, the listener is removed from the list. When the handling of a event fails with a RemoteException, the users online state is set to false.
