Tnx for such quick reply.

Well, the problem is that I will like to use method with different signature and from class which doesn't extends Facade, but rather just implement IFacade. On the other hand, I will like to use Notifier implementation. Heh, I guess I'm a little bit demanding :-)

But never mind, It is not so big issue for me. I was just thinking that introduction of getter will easily solve my needs without breaking anything.

I was wondering if Notifier class can be redefined a little. Currently, it has "facade" member initialized with "Facade.getInstance()". If one wants to use different IFacade implementation in Notifier subclasses, it is impossible. Therefore, if I may suggest, I believe Notifier can be made more extensible by using setter and getter (or just getter) instead of instance variable. Then, it will become possible to override it in subclasses.

I think this is already implemented that way in multicore version.
