package java.awt.event;

import java.util.EventListenerProxy;
import java.awt.AWTEvent;

A class which extends the EventListenerProxy, specifically
for adding an AWTEventListener for a specific event mask.
Instances of this class can be added as AWTEventListeners to
a Toolkit object.

The getAWTEventListeners method of Toolkit can
return a mixture of AWTEventListener and
AWTEventListenerProxy objects.
