设计模式-适配器模式

适配器模式：将一个类的接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。

模式比较简单，直接贴代码：

#ifndef Duck_h
#define Duck_h
#include <iostream>
class Duck {
public:
    virtual void quack()=0;
};

class MallardDuck:public Duck{
public:
    void quack(){
        printf("MallardDuck Quack\n");
    }
};
#endif /* Duck_h */

#ifndef Turkey_h
#define Turkey_h
#include <iostream>
class Turkey{
public:
    //火鸡不能呱呱叫，只能咯咯叫
    void gobble(){
        printf("Turkey Gobble\n");
    }
};
#endif /* Turkey_h */

#ifndef TurkeyAdapter_h
#define TurkeyAdapter_h
#include "Duck.h"
#include "Turkey.h"
class TurkeyAdapter:public Duck{
private:
    Turkey* turkey;
public:
    TurkeyAdapter(Turkey* turkey){
        this->turkey = turkey;
    }
    void quack(){
        turkey->gobble();
    }
};

#endif /* TurkeyAdapter_h */

#include <iostream>
#include "Duck.h"
#include "Turkey.h"
#include "TurkeyAdapter.h"
void testQuack(Duck* duck);
int main(int argc, const char * argv[]) {
    auto duck = new MallardDuck();
    auto turkey = new Turkey();
    auto turkeyAdapter = new TurkeyAdapter(turkey);

    testQuack(duck);
    testQuack(turkeyAdapter);//使用适配器使火鸡兼容Duck*参数
    return 0;
}
void testQuack(Duck* duck){//客户只接受Duck*类型
    duck->quack();
}
