1,不知道大家有无买过电子产品,港货的那中充电的时候是不符合大陆插头的我们就需要买1个转换器给它转换,或变压器甚么的,将电压变低或变高,适配器就是这功能
2,没甚么好解释的,直接代码吧:
// 适配器模式.cpp : 定义控制台利用程序的入口点。
//
#include "stdafx.h"
#include <iostream>
#include <string>
using namespace std;
class Player
{
public:
string name;
Player(string name) :name(name){};
virtual void attach() = 0;
virtual void defence() = 0;
};
class Forword :public Player{
public:
Forword(string name) : Player(name){};
void attach(){
cout << name<<"forword attach"<<endl;
}
void defence(){
cout << name << "forword defence" << endl;
}
};
class Center :public Player{
public:
Center(string name) :Player(name){}
void attach(){
cout << name << "Center attach" << endl;
}
void defence(){
cout << name << "Center defence" << endl;
}
};
class ForeignCenter{
public:
string name;
ForeignCenter(string name){
this->name = name;
}
void myAttach(){
cout << name << "foreign myattach" << endl;
}
void myDefence(){
cout << name << "foreign myDefence" << endl;
}
};
//适配器
class Traslator :public Player{
private :
ForeignCenter *fc;
public:
Traslator(string name) :Player(name){
fc = new ForeignCenter(name);
}
void attach(){
fc->myAttach();
}
void defence(){
fc->myDefence();
}
};
int _tmain(int argc, _TCHAR* argv[])
{
Player *p1 = new Center("中卫");
p1->attach();
p1->defence();
//将姚明转换为外员(本身不是外员哦)
Traslator *t1 = new Traslator("姚明");
t1->attach();
t1->defence();
cin.get();
return 0;
}
3,
适配器模式是1种补救手段，是为了复用已有类的代码并且将其适配到客户端需要的接口上去。如果写补钉的话,就需要这个模式
