Method Details

addListener

void addListener(IModelChangeListener listener)

Add a listener to the event source. Listeners will not be added twice. Subsequent calls to addListener(IModelChangeListener) will not affect the number of events that the listener receives. removeListener(IModelChangeListener) will remove the listener immediately independently from the number of invocations of addListener(IModelChangeListener) for the given listener.

Parameters:

listener - the listener to be registered. May not be null.

removeListener

void removeListener(IModelChangeListener listener)

Immediately removes a registered listener from the source. However if removeListener(IModelChangeListener) is called during a notification, the removed listener will still receive the event. If the listener has not been registered before, the removeListener(IModelChangeListener) does nothing.

Parameters:

listener - the listener to be removed. May not be null.
