设计模式－建造模式（一碗牛肉面的制造过程）

设计模式－建造模式

摘要：介绍Gof设计模式创建模式中的建造模式，结合一个生活中的一个，来说明建造模式的使用场合和使用方法
          工厂模式中，创建对象是直接创建的，而对一个复杂的对象来说，用建造模式更适合，它一步一步的创建一个复杂对象。
         基本的模式是这样的
interface  Builder
{
    //建造“零件”
    void BuildPart1();
    void BuildPart2();
    
    //返回产品
    Product GetProduct();
}

这样从此类继承的建造者，可以根据上面定义的两种建造零件方法，构造任意复杂的建造者。

开始做牛肉面条啦

2.刀削面做好了

3.面汤做好了

4.香菜洗好了

一碗香喷喷的牛肉刀削面做好啦！
