Design Pattern: Factory
07/12/11 21:41 Category: Design Pattern | Software engineering
The Factory is a design pattern used when it is needed to create objets without having to specify the exact class to implement. We only know need to know the general usage of the implemented class, not the internal operations.
That’s why a Factory return objets who are either :
- from a class extending a known abstract class,
- or from a class implementing a known interface.
