public class TooManyListenersException

extends Exception

The TooManyListenersException Exception is used as part of the Java Event model to annotate and implement a unicast special case of a multicast Event Source.

The presence of a throws TooManyListenersException clause on any given concrete implementation of the normally multicast semantic void add < EventListenerType > () event listener registration pattern is used to annotate that interface as implementing a unicast Listener special case, that is, that one and only one Listener may be registered on the particular event listener source concurrently.
