网上有很多设计模式方面的内容，这篇写给像我一样的菜鸟 供大家体会 注该代码为转载代码 写的很好 拿来用一下 本着开源的精神 望原作者见谅
// Bridge模式是构造型的设计模式之一。Bridge模式基于类的最小设计原则，通过使用封装，聚合以及继承等行为来让不同的类承担不同的责任。它的主要特点是把抽象（abstraction）与行为实现（implementation）分离开来，从而可以保持各部分的独立性以及应对它们的功能扩展。

// 可以看到，通过对象组合的方式，Bridge 模式把两个角色之间的继承关系改为了耦合的关系，从而使这两者可以从容自若的各自独立的变化，这也是Bridge模式的本意。
