benefit os having a factory for object creation?
- by ajsie
im trying to understand the factory design pattern.
i dont understand why it's good to have a middleman between the client and the product (object that the client wants).
example with no factory:
$mac = new Mac();
example with a factory:
$appleStore = new AppleStore();
$mac = $appleStore->getProduct('mac');
how does the factory pattern decouple the client from the product?
could someone give an example of a future code change that will impact on example 1 negative, but positive in example 2 so i understand the importance of decoupling?
thanks
