Method Detail

addListener

void addListener(IResourceDescription.Event.Listener listener)

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

Parameters:

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

removeListener

void removeListener(IResourceDescription.Event.Listener listener)

Immediately removes a registered listener from the source. However if removeListener(org.eclipse.xtext.resource.IResourceDescription.Event.Listener) is called during a notification, the removed listener will still receive the event. If the listener has not been registered before, the removeListener(org.eclipse.xtext.resource.IResourceDescription.Event.Listener) does nothing.

Parameters:

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

notifyListeners

void notifyListeners(IResourceDescription.Event event)

Notify listeners about the given event.

Parameters:

event - the fired event. My not be null.
