Beside the run-time flexibility this provides (you can change the class being instantiated more easily), this can support singleton classes: the class factory object checks to see if it has already created a singleton object (it obviously will have to maintain a reference to the singleton object) and if so, return the reference to that object rather than creating a new one.

LOL... I´m looking for how to make a Singleton behavior in my Abstract Factory class... it´s true, not a joke. I have program my Abstract Factory and it support Singleton Classes already, but I need Singleton behavior for my Factory it self.

Thanks.
