VetoableChangeListenerProxy
public class VetoableChangeListenerProxy extends EventListenerProxy implements VetoableChangeListener(Code)
A class which extends the EventListenerProxy specifically for associating a VetoableChangeListener with a "constrained" property. Instances of this class can be added as a VetoableChangeListener to a bean which supports firing VetoableChange events.

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