extends java.lang.Object

This class implements the methods defined by DataItemChangeListener and DataItemShapeChangeListener and can be used by a consumer as a base class for implementing a change listener class. All methods in this class have empty-body implementations. Thus, to use this class, the consumer should subclass it and override the methods for handling events of interest.
