Hi,

In the Design Patterns book by GoF, it says that
the reference to the AbstractProduct (or
ConcreteProduct) never occurs in the client code.
Clients will only call the CreateXXX() methods
from the concrete factory classes.

Then how will the client use the objects that the CreateXXX() methods
construct?

I am assuming the following relationships:

AbsractFactory (interface)
CreateProductA() (signature only)
CreateProductB() ( -do- )

ConcreteFactory1 (class) implements AbsractFactory
Implementations of the CreateXXX() methods
are here.
Supposed to create Product1A and Product1B
objects.

ConcreteFactory2 (class) implements AbsractFactory
Implementations of the CreateXXX() methods are
here.
Supposed to create Product2A and Product2B
objects.
