设计模式之抽象工厂模式 

有些情况下我们需要根据不同的选择逻辑提供不同的构造工厂，而对于多个工厂而言需要一个统一的抽象工厂
  1 class System{}
  2 class Soft{}
  3 
  4 class MacSystem extends System{}
  5 class MacSoft extends Soft{}
  6 
  7 class WinSystem extends System{}
  8 class WinSoft extends Soft{}
  9 
 10 /**
 11  * AbstractFactory class[抽象工厂模式]
 12  */
 13 interface AbstractFactory {
 14     public function CreateSystem();
 15     public function CreateSoft();
 16 }
 17 
 18 class MacFactory implements AbstractFactory{
 19     public function CreateSystem()
 20     {
 21         // TODO: Implement CreateSystem() method.
 22         return new MacSystem();
 23     }
 24     public function CreateSoft()
 25     {
 26         // TODO: Implement CreateSoft() method.
 27         return new MacSoft();
 28     }
 29 }
