Abstract Factory Pattern

Abstract

Intent • "Provide an interface for creating families of related or dependent objects without specifying their concrete classes." • provide a simple creational interface for a complex family of classes • Client does not have to know any of those details. • avoid naming concrete classes • Clients use abstract creational interfaces and abstract product interfaces. Concrete classes can be changed without affecting clients. • Clients can stay blissfully unaware of implementation details • This is critically important! Why is this so important?
