Class VetoableChangeListenerProxy

java.lang.Object

java.util.EventListenerProxy<VetoableChangeListener>

java.beans.VetoableChangeListenerProxy

All Implemented Interfaces:: VetoableChangeListener, EventListener

public class VetoableChangeListenerProxy extends EventListenerProxy<VetoableChangeListener> implements VetoableChangeListener

A class which extends the EventListenerProxy specifically for adding a VetoableChangeListener with a "constrained" property. Instances of this class can be added as VetoableChangeListeners to a bean which supports firing vetoable change events.

If the object has a getVetoableChangeListeners method then the array returned could be a mixture of VetoableChangeListener and VetoableChangeListenerProxy objects.
