java.util
Class EventListenerProxy

java.lang.Object
  java.util.EventListenerProxy

All Implemented Interfaces:

EventListener

Direct Known Subclasses:

AWTEventListenerProxy, PropertyChangeListenerProxy, VetoableChangeListenerProxy

public abstract class EventListenerProxy
extends Object
implements EventListener

An abstract wrapper class for an EventListener class which associates a set of additional parameters with the listener. Subclasses must provide the storage and accessor methods for the additional arguments or parameters. Subclasses of EventListenerProxy may be returned by getListeners() methods as a way of associating named properties with their listeners. For example, a Bean which supports named properties would have a two argument method signature for adding a PropertyChangeListener for a property: public void addPropertyChangeListener(String propertyName, PropertyChangeListener listener); If the Bean also implemented the zero argument get listener method: public PropertyChangeListener[] getPropertyChangeListeners(); then the array may contain inner PropertyChangeListeners which are also PropertyChangeListenerProxy objects. If the calling method is interested in retrieving the named property then it would have to test the element to see if it is a proxy class.
