Class SimpleChangeListener

java.lang.Object
  org.eclipse.jpt.utility.model.listener.SimpleChangeListener

All Implemented Interfaces:

java.util.EventListener, ChangeListener, CollectionChangeListener, ListChangeListener, PropertyChangeListener, StateChangeListener, TreeChangeListener

Direct Known Subclasses:

CommandChangeListener

public abstract class SimpleChangeListener
extends java.lang.Object
implements ChangeListener

Convenience abstract implementation of ChangeListener. All change notifications are funneled through a single method. This class can be used by subclassing it and overriding either modelChanged(ChangeEvent) (if access to the event is required) or modelChanged() (if access to the event is not required).

Provisional API: This class is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.
