桥接模式

【1】什么是桥接模式?

【2】桥接模式的代码示例

示例代码:

 1 #include <iostream>
 2 #include <string>
 3 using namespace std;
 4 
 5 class HandsetSoft
 6 {
 7 public:
 8     virtual void run() = 0;
 9 };
10 
11 class HandsetGame : public HandsetSoft
12 {
13 public:
14     void run()
15     {
16         cout << "运行手机游戏" << endl;
17     }
18 };
19 
20 class HandsetAddressList : public HandsetSoft
21 {
22 public:
23     void run()
24     {
25         cout << "运行手机通讯录" << endl;
26     }
27 };
28 
29 class HandsetBrand
30 {
31 protected:
32     HandsetSoft *soft;
33 public:
34     void setHandsetSoft(HandsetSoft *soft)
35     {
36         this->soft = soft;
37     }
38     virtual void run() = 0;
39 };
40 
41 class HandsetBrandN : public HandsetBrand
42 {
43 public:
44     void run()
45     {
46         soft->run();
47     }
48 };
49 
50 class HandsetBrandM : public HandsetBrand
51 {
52 public:
53     void run()
54     {
55         soft->run();
56     }
57 };
58 
59 int main()
60 {
61     HandsetBrand *hb;
62     hb = new HandsetBrandM();
63     
64     hb->setHandsetSoft(new HandsetGame());
65     hb->run();
66     hb->setHandsetSoft(new HandsetAddressList());
67     hb->run();
