MA (13.08.2001 10:59:25) When registered as Java element delta listener, you get also deltas coming from working copys, like when the user types on the keyboard. This results in many deltas sent to all delta listeners. Performance suggestion: There could be two kinds of delta listeners, some that are not interested in working copy deltas. NOTES: PM (10/8/2001 12:17:19 PM) Nice to have

Defer - this would be an API change
Added notion of event type, allowing to register reconcile specific listeners. See /** * Adds the given listener for changes to Java elements. * Has no effect if an identical listener is already registered. * After completion of this method, the given listener will be registered for exactly * the specified events. If they were previously registered for other events, they * will be deregistered. * <p> * Once registered, a listener starts receiving notification of changes to * java elements in the model. The listener continues to receive * notifications until it is replaced or removed. * </p> * <p> * Listeners can listen for several types of event as defined in <code>ElementChangeEvent</code>. * Clients are free to register for any number of event types however if they register * for more than one, it is their responsibility to ensure they correctly handle the * case where the same java element change shows up in multiple notifications. * Clients are guaranteed to receive only the events for which they are registered. * </p> * * @param listener the listener * @param eventMask the bit-wise OR of all event types of interest to the listener * @see IElementChangedListener * @see ElementChangedEvent * @see #removeElementChangedListener(IElementChangedListener) * @since 2.0 */ public static void addElementChangedListener(IElementChangedListener listener, int eventMask) Closing
