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.
