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.
