Inherit @Observer annotation

m23 Dec 7, 2009 4:09 PM

Dear all!

I'm a Java newbie and I'd really appreciate some help:

I just created a base class which defines the event handling method doSomething with the observer annotation someEvent.

Am I right that if I wanted to create a sub class and overwrite the doSomething method I would have to redeclare the @Observer annotation? Is there a way to inherit observer annotations?

Thank you for your help!
Michael

Well, of course the really easy way to do this is like this:

In your superclass you have this (NOTE: This code is NOT compiled or checked just typed straight out of my head early in the morning :P)

public abstract class superAbstractObserverClass { abstract void observeMethod(); @Observer("booyah") public void observerBooyah() { observeMethod(); } }

So, now all implementations of superAbstractObserverClass have to implement the observerMethod.

There's probably much better ways of doing this but... best I could come up with at the moment :P

Oh, and this is not tested so I'm not even 100% sure that it works... but it should :P
