Notes to Implementers
StopListening(Object) implementations should remove the class handler as added by the StartListening(Object) method. Removing a listener should not clear the listener list. Instead, it should only disconnect the class handler (perhaps temporarily). Other methods are available for clearing the entire list, such as the Purge(Object, Object, Boolean) method with the purgeAll
parameter set to true
.
