This chapter covers the Abstract Factory pattern.
GoF Definition
Provide an interface for creating families of related or dependent objects without specifying their concrete classes.
Note
The Abstract Factory pattern will make more sense to you if you understand the Simple Factory pattern (Chapter 24) and the Factory Method pattern (Chapter 4). The Simple Factory pattern does not fall directly into the Gang of Four design patterns, so the discussion of that pattern appears in Part II of the book. I suggest that you read Chapters 4 and 24 before jumping into this one.
