Method Detail

addListener

public void addListener(IResourceDescription.Event.Listener listener)

Description copied from interface: IResourceDescription.Event.Source

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

Specified by:

addListener in interface IResourceDescription.Event.Source

Parameters:

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

addListeners

public void addListeners(Collection<IResourceDescription.Event.Listener> listeners)

removeListener

public void removeListener(IResourceDescription.Event.Listener listener)

Description copied from interface: IResourceDescription.Event.Source

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

Specified by:

removeListener in interface IResourceDescription.Event.Source

Parameters:

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

removeListeners

public void removeListeners(Collection<IResourceDescription.Event.Listener> listeners)

Description copied from interface: IResourceDescription.Event.Source
