Class EventListenerCollection

java.lang.Object
  org.gwtopenmaps.openlayers.client.event.EventListenerCollection

public class EventListenerCollection
extends Object

The EventListenerCollection serves to maintain references to EventListeners, and keeps hold of the properties necessary to unregister EventListeners. When an EventListener is added to the EventListener collection it is passed all the information to add it as a listener for events a particular widget fires.
