package org.apache.batik.gvt.event;

An abstract adapter class for receiving graphics node change
events. The methods in this class are empty. This class exists as
convenience for creating listener objects.
Extend this class to create a GraphicsNodeChangeEvent
listener and override the methods for the events of interest. (If
you implement the GraphicsNodeChangeListener interface, you
have to define all of the methods in it. This abstract class
defines null methods for them all, so you can only have to define
methods for events you care about.)
