Design Pattern - Adapter Pattern

适配器模式，超简单的一个设计模式。

GOF的《设计模式》中解释如下：

将一个类的接口转换成客户希望的另外一个接口，Adapter使原本由于接口不兼容而不能一起工作的类可以一起工作

写个简单的例子如下：

1. public interface IShape
2. {
3.     public void SetLocation(Location location);
4.  
5.     public Location GetLocation();
6. }
7.  
8. class Square : IShape
9. {
10.     public void SetLocation(Location location)
11.     {
12.         throw new NotImplementedException();
13.     }
14.  
15.     public Location GetLocation()
16.     {
17.         throw new NotImplementedException();
18.     }
19. }
20.  
21. class XXCircle
22. {
23.     public void SetLocation(Location location)
24.     {
25.         throw new NotImplementedException();
26.     }
27.     public Location GetLocation()
28.     {
29.         throw new NotImplementedException();
30.     }
31. }
32.  
33. class Circle : IShape
34. {
35.     XXCircle myXXCircle;
36.  
37.     public Circle(XXCircle myXXCircle)
38.     {
39.         this.myXXCircle = myXXCircle;
40.     }
41.  
42.     public Circle()
43.     {
44.         this.myXXCircle = new XXCircle();
45.     }
46.     
47.     #region IShape Members
48.  
49.     public void SetLocation(Location location)
50.     {
51.         myXXCircle.SetLocation(location);
52.     }
53.  
54.     public Location GetLocation()
55.     {
56.         return myXXCircle.GetLocation();
57.     }
58.  
59.     #endregion
60. }
