这样做能把客户类和具体子类的实现解耦,客户类不再需要知道有哪些子类以及应当实例化哪个子类。客户类往往有多个,如果不使用简单工厂,那么所有的客户类都要知道所有子类的细节。而且一旦子类发生改变,例如增加子类,那么所有的客户类都要进行修改。

装饰者(Decorator)和具体组件(ConcreteComponent)都继承自组件(Component),具体组件的方法实现不需要依赖于其它对象,而装饰者组合了一个组件,这样它可以装饰其它装饰者或者具体组件。所谓装饰,就是把这个装饰者套在被装饰者之上,从而动态扩展被装饰者的功能。装饰者的方法有一部分是自己的,这属于它的功能,然后调用被装饰者的方法实现,从而也保留了被装饰者的功能。可以看到,具体组件应当是装饰层次的最低层,因为只有具体组件的方法实现不需要依赖于其它对象。
