设计模式之适配器模式（类模式）

类模式

#pragma once
class Target
{
public:
    Target();
    virtual ~Target();

    virtual void Request();
};

#include "Target.h"
#include <iostream>


Target::Target()
{
}


Target::~Target()
{
}

 

#pragma once
class Adaptee
{
public:
    Adaptee();
    ~Adaptee();

    void SpecificRequest();
};

#include "Adaptee.h"
#include <iostream>


Adaptee::Adaptee()
{
}


Adaptee::~Adaptee()
{
}

void Adaptee::SpecificRequest()
{
    std::cout << "Adaptee::SpecificRequest" << std::endl;
}

 

#pragma once
#include "Target.h"
#include "Adaptee.h"

class Adapter :
    public Target, private Adaptee
{
public:
    Adapter();
    ~Adapter();

    void Request();
};

#include "Adapter.h"


Adapter::Adapter()
{
}


Adapter::~Adapter()
{
}

void Adapter::Request()
{
    this->SpecificRequest();
}

 

测试

#include <iostream>
#include "Adapter.h"

int main()
{
    Target *tar = new Adapter();
    tar->Request();
　　 // 内存释放

    if (tar)
    {
        delete tar;
        tar = NULL;
    }

    std::cout << "Hello World!\n"; 
}
