设计模式之适配器模式

使用场合：双方都不适合修改的时候,可以考虑使用适配器模式

示例一：

#include <iostream>
#include <string>


using namespace std;


class Target
{
public:
    virtual void Request()
    {
cout << "普通的请求" << endl;
    }
};


class Adaptee
{
public:
    void SpecificalRequest()
    {
cout << "特殊请求" << endl;
    }
};


class Adapter : public Target
{
private:
    Adaptee* ada;
public:
    virtual void Request()
    {
ada->SpecificalRequest();
Target::Request();
    }
    
    Adapter()
    {
ada = new Adaptee();
    }
    ~Adapter()
    {
delete ada;
    }
};


//客户端
int main()
{
    Adapter* ada = new Adapter();
    ada->Request();
    
    delete ada;
    
    return 0;
}

示例二：

#include <iostream>
#include <string>

using namespace std;

class Player
{
protected:
    string name;
public:
    Player(string strName){name = strName;}
    virtual void Attack()=0;
    virtual void Defense()=0;
};

class Forwards : public Player
{
public:
    Forwards(string strName) 
: Player(strName)
    {
    }
public:
    virtual void Attack()
    {
cout << name << "前锋进攻" << endl;
    }
    
    virtual void Defense()
    {
cout << name << "前锋防守" << endl;
    }
};

class Center : public Player
{
public:
    Center(string strName) : Player(strName){}
public:
    virtual void Attack()
    {
cout << name << ",中场进攻" << endl;
    }
    
    virtual void Defense()
    {
cout << name << ",中场防守" << endl;
    }
};

//为中场翻译
class TransLater : public Player
{
private:
    Center* player;
public:
    TransLater(string strName):Player(strName)
    {
player = new Center(strName);
    }
    
    virtual void Attack()
    {
player->Attack();
    }
    
    virtual void Defense()
    {
player->Defense();
    }
};

//客户端
int main()
{
    Player* p = new TransLater("Messi Lee");
    p->Attack();
    
    return 0;
}
