一、定义

适配器模式：将一个类的借口，转换成客户期望的另一个接口。适配器让原本接口不兼容的类可以合作无间。

二、模式结构

适配器模式包含如下角色：

• Target：目标抽象类
• Adapter：适配器类
• Adaptee：适配者类
• Client：客户类

适配器模式有对象适配器和类适配器两种实现：

对象适配器：

类适配器：

三、代码样例

#include 
     
      #include "Adapter.h"#include "Adaptee.h"#include "Target.h"using namespace std;int main(int argc, char *argv[]){    Adaptee * adaptee  = new Adaptee();    Target * tar = new Adapter(adaptee);    tar->request();        return 0;}
