Method Details

addListener

public void addListener(IModelChangeListener listener)

Description copied from interface: IModelChangeSource

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

Specified by:

addListener in interface IModelChangeSource

Parameters:

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

removeListener

public void removeListener(IModelChangeListener listener)

Description copied from interface: IModelChangeSource

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

Specified by:

removeListener in interface IModelChangeSource

Parameters:

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

modelChanged

public void modelChanged(org.eclipse.emf.common.notify.Notification event)

Description copied from interface: IModelChangeListener

The source will invoce this method to announce changed resource. The event will never be null. However, it may contain an empty list of deltas.

Listeners are free to remove themselves from the sender of the event or add other listeners. However added listeners will not be informed about the current change.

This event fired synchronously.

Specified by:

modelChanged in interface IModelChangeListener

Parameters:

event - the fired event. Will never be null.

Throws:

IllegalArgumentException - if event is null.
