Interface ModelChangeEvent

All Superinterfaces:

ModelChangeTypes

All Known Implementing Classes:

BasicModelChangeEvent

public interface ModelChangeEvent

extends ModelChangeTypes

Event that is broadcasted to notify interested ModelChangeListeners of a change in state of a model object implementing ModelChangeEventSource. It contains:

• the source of the event (ie the model object that changed),
• the Selector identifying the property that changed,
• and a 'type' of change (see ModelChangeTypes).

Note that the event does not contain the actual data that changed, unlike JavaBeans PropertyChangeEvent.
