Examples of org.apache.tapestry.event.ChangeObserver

org.apache.tapestry.event.ChangeObserver
May observe changes in an object's properties. This is a "weak" variation on JavaBean's style bound properties. It is used when there will be at most a single listener on property changes, and that the listener is not interested in the old value. @author Howard Lewis Ship @version $Id: ChangeObserver.java 243791 2004-02-19 17:38:13Z hlship $
