public class ListenerSupport<E>
extends java.util.ArrayList<E>
implements java.io.Serializable

This is an utility class that can be used by beans that need support for handling listeners and firing events. You can use an subclass of this class as a member field of your bean and delegate work to it. It handles the work for a listener support subclass managing the Vector of listeners. It knows nothing about firing events to the listeners.
