## 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 `VetoableChangeListener`s 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.

  Since:
    1.4

    `EventListenerProxy`, `VetoableChangeSupport.getVetoableChangeListeners()`
