Design Patterns discussion

No, an Abstract Factory is *not* a factory of factories.

With Abstract Factory, you change the behaviour of *other* objects by
passing them different factory objects. Therefore it's object based.

With Factory Method, you change the behaviour of a class by creating
different subclasses. Therefore it's class based.

Did that help?

BTW, please post in plain text, not in HTML. Thanks.

Hi,
    Thankyou very much for your reply. So, if simply put, can
AbstractFactory can be defined as a factory of factories? But, in that
case, how can one be class creational while other is object creational?
How can Abstract factory's behaviour be changed using object delegation?
