Bridge模式将类的定义与实现彻底解耦，采用组合的方式进行处理。
代码如下：
1
#include <iostream>
2#include <stdio.h>
3#include <stdlib.h>
4#include <stdarg.h>
5
6#define STRLEN 100
7class CImplement
8
{
9
protected:
10 CImplement()
11
{
12
13
}
14public:
15 ~CImplement()
16 {
17
18 }
19
20 virtual void Operatorion() = 0;
21 virtual void PrintMsg(char * format,) = 0;
22
23
};
24
25
26class CExtendImp:public CImplement
27{
28public:
29 CExtendImp()
30 {
31
32 }
33
34 ~CExtendImp()
35 {
36
37 }
38
39 void Operatorion()
40 {
41 PrintMsg("%s\t %s","Hello" ,"World!");
42 }
43
44 void PrintMsg(char * format,)
45 {
46 va_list tmp_list;
47 va_start(tmp_list,format);
48 char* c_buffer = new char[STRLEN];
49 vsprintf(c_buffer,format,tmp_list);
50 fprintf(stderr,"\r\n*********\r\n%s\r\n",c_buffer);
51 }
52};
53
54class CAbstract
55{
56protected:
57 CAbstract()
58 {
59
60 }
61public:
62 ~CAbstract()
63 {
64
65 }
66
67 virtual void operation() = 0;
68};
69
70class CExtendAbstract
71{
72public:
73 CExtendAbstract(CImplement * data)
74 {
75 _imp = NULL;
76 _imp = data;
77 }
78 ~CExtendAbstract()
79 {
80
81 }
82
83 void operation()
84 {
85 _imp->Operatorion();
86 }
87protected:
88 CImplement * _imp;
89};
90
91int main(int argc ,char * argv[])
92{
93 CImplement * value = new CExtendImp();
94 CExtendAbstract* abstr = new CExtendAbstract(value);
95 abstr->operation();
96}
