Example 1 with IElementChangedListener

use of org.erlide.engine.model.root.IElementChangedListener in project erlide_eclipse by erlang.

the class ErlModelDeltaManager method fire.

Example 2 with IElementChangedListener

use of org.erlide.engine.model.root.IElementChangedListener in project erlide_eclipse by erlang.

the class ErlModel method notifyListeners.

public void notifyListeners(final IErlElementDelta deltaToNotify, final int eventType, final IElementChangedListener[] listeners, final int[] listenerMask, final int listenerCount) {
    final ElementChangedEvent extraEvent = new ElementChangedEvent(deltaToNotify, eventType);

                // $NON-NLS-1$//$NON-NLS-2$
                ErlLogger.debug("Listener #" + (i + 1) + "=" + listener.toString());
                start = System.currentTimeMillis();
            }
            // wrap callbacks with Safe runnable for subsequent listeners to
            // be called
            // when some are causing grief
            SafeRunner.run(new ISafeRunnable() {

                @Override
                public void handleException(final Throwable exception) {
                    // CCorePlugin.log(exception, "Exception occurred in
                    // listener of C
