Design Patterns discussion

["Jacob George" <jacobg AT atinav.com>]

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?

 

                                                                                                                        regards Jacob

Factory Method is about deciding which class to instantiate.  Abstract
factory is about ensuring that that classes that you are instantiate are a
matched set.  Abstract factory may use factory method to decide which set
of classes it will instantiate.

Hi,
    I am new to this group and is presently trying to understand creational
patterns. I got confused by the "Factory method" pattern and "Abstract
Factory" pattern. Both are used for instantiating objects, right? But one
is class creational while other is object creational; this point I doesn't
understand clearly.
