橋接模式：
將抽象部分和它的實現(xiàn)部分相分離開來，以使它們可以單獨地變化。

UML圖：

主要包括：

1. Abstraction:定義了抽象部分的接口，操作一個實現(xiàn)部分對象的引用。
2. RefinedAbstraction:繼承自抽象部分的類。
3. Implementor：實現(xiàn)部分的接口。
4. ConcreteImplementor：實現(xiàn)了Implementor定義的接口的具體類。

C++代碼如下：

#include <iostream>using namespace std;class Implementor
{public:virtual void operationImpl()=0;
};class ConcreteImplementorA:public Implementor
{public:void operationImpl(){cout<<"ConcreteImplementorA::operationImpl"<<endl;}};class ConcreteImplementorB:public Implementor
{public:void operationImpl(){cout<<"ConcreteImplementorB::operationImpl"<<endl;}};class Abstraction
{public:virtual void operation()=0;void setImplementor(Implementor * i){impl=i;}Implementor * getImplementor(){return impl;}protected:Implementor * impl;     
};class RefinedAbstraction:public Abstraction
{public:void operation(){impl->operationImpl();}
};int main()
{cout<<"橋接模式例子"<<endl;Abstraction * ab=new RefinedAbstraction();Implementor * cia=new ConcreteImplementorA();ab->setImplementor(cia);ab->operation();Implementor * cib=new ConcreteImplementorB();ab->setImplementor(cib);ab->operation();delete cia;delete cib;delete ab;return 0;
}

下面是一個具體的例子，看這個具體的例子可能好理解一些,摘自大話設(shè)計模式：

1. Abstraction為Phone(手機)。
2. RefinedAbstraction為Samsung(三星手機)，Huawei(華為手機)。
3. Implementor為Game(手機游戲)。
4. ConcreteImplementor為NeedForSpeed(極品飛車)，QQGame(QQ游戲)，FruitNinjia(水果忍者)。

UML類圖為：

C++代碼：

#include <iostream>using namespace std;class Game
{public:virtual void play()=0;
};class NeedForSpeed :public Game
{public:virtual void play(){cout<<"need for speed play"<<endl;}
};class QQGame :public Game
{public:virtual void play(){cout<<"QQGame play"<<endl;}
};class FruitNinjia:public Game
{public:virtual void play(){cout<<"Fruit Ninjia play"<<endl;}
};class Phone
{public:virtual void run()=0;void setGame(Game *g){   game=g;}   Game * getGame(){return game;}protected:Game *game;
};class Samsung:public Phone
{public:virtual void run(){cout<<"Samsung :";game->play();}
};class HuaWei:public Phone
{public:virtual void run(){cout<<"HuaWei :";game->play();}};int main()
{cout<<"橋接模式真實的例子，不同的手機品牌和手機游戲"<<endl;Phone *samsung=new Samsung();Phone *huawei=new HuaWei();Game * needForSpeed=new NeedForSpeed();Game * qqGame=new QQGame();Game * fruit=new FruitNinjia();samsung->setGame(qqGame);samsung->run();huawei->setGame(needForSpeed);huawei->run();samsung->setGame(fruit);samsung->run();delete samsung;delete huawei;delete needForSpeed;delete qqGame;delete fruit;return 0;}
