Observable class

[Naoufel El Bachir]

Hi,
I was looking at the Observable class and have a few
questions:

- Is there any reason this class is not abstract ?
- What happens when Observable is deleted ? Does not
it need to notify Observers in its destructor ?
- Why is Observable::notifyObservers() still public
and not protected as suggested in the Ehancement
Proposal ?

Thanks for any clarifications

Is there any reason to be abstract ;-)

Classes derived from Observers contain a "link" to Observable class using Handle
  or shared_ptr. It ensure that observed classes are not destroyed since
Observer class observes.
