Why do I have to write this code? ListDataEvent has the type. Why are there three different methods to call on the listener? The *listener* should unpack the event!
private void notifyListeners(ListDataEvent lde) {
synchronized (_listeners) {
for (ListDataListener ldl : _listeners) {
switch (lde.getType()) {
case ListDataEvent.CONTENTS_CHANGED:
ldl.contentsChanged(lde);
break;
case ListDataEvent.INTERVAL_ADDED:
ldl.intervalAdded(lde);
break;
