**Intent:** Provide an interface for creating families of related or dependent
|
||
|
|
objects without specifying their concrete classes.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
**Applicability:** Use the Abstract Factory pattern when
|
||
|
|
|
||
|
|
* a system should be independent of how its products are created, composed and represented
|
||
|
|
* a system should be configured with one of multiple families of products
|
||
|
|
* a family of related product objects is designed to be used together, and you need to enforce this constraint
|
||
|
|
* you want to provide a class library of products, and you want to reveal just their interfaces, not their implementations
|
||
|
|
|
||
|
|
**Real world examples:**
|
||
|
|
