All Implemented Interfaces:
VetoableChangeListener, EventListener

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

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