PropertyChangeListenerProxy

public class PropertyChangeListenerProxy extends EventListenerProxy<PropertyChangeListener>
implements PropertyChangeListener

A class which extends the EventListenerProxy specifically for adding a PropertyChangeListener with a "bound" property. Instances of this class can be added as PropertyChangeListeners to a bean which supports firing property change events.

If the object has a getPropertyChangeListeners method then the array returned could be a mixture of PropertyChangeListener and PropertyChangeListenerProxy objects.
