[news.eclipse.tools.emf] Re: Custom code for list of enums

[Tomas Zijdemans <trommas@xxxxxxxxx>]

Ah, I see :)

I created this:

class test extends BasicEList<InstantiationLevel> {
@Override
protected void didAdd(int index, InstantiationLevel newObject) {
	super.didAdd(index, newObject);
	System.out.println("didAdd :)");
	}
@Override
protected void didRemove(int index, InstantiationLevel oldObject) {
	super.didRemove(index, oldObject);
	System.out.println("didRemove :)");
	}
}

But, for the final step, how do I hook this to my EList?


Thanks for helping,
