Class ChangeObserver

java.lang.Object

ca.weblite.shared.event.ChangeObserver

public class ChangeObserver
extends Object

A utility class for observing changes on TextAreas. API lends itself to expanding to other types of of components also. It subscribes to receive action events from the textareas, but only propagates the event to its listeners if the value of the text area has changed since the last event.

Note	This class isn’t used by CodeRAD for its property binding functionality. It is still a useful class for monitoring plain old text areas, though.
