Bridge Pattern

1.Bridge Pattern :使用组合的方式将“抽象”和“实现”彻底的解耦。这里的实现不是指继承基类，实现基类接口，而是指通过对象的组合实现用户的需求。

面向对象分析和设计中的原则: Favor Compsition Over Inheritance.

2.Bridge Pattern 模式结构图

#include "AbstractionImp.h"
#include <iostream>
using namespace std;

AbstractionImp::AbstractionImp()
{

}
AbstractionImp::~AbstractionImp()
{

}
void AbstractionImp::Operation()
{
cout<<"AbstractionImp....imp..."<<endl;
}
ConcreteAbstractionImpA::ConcreteAbstractionImpA()
{

}
ConcreteAbstractionImpA::~ConcreteAbstractionImpA()
{

}
void ConcreteAbstractionImpA::Operation()
{
cout<<"ConcreteAbstractionImpA...."<<endl;
}
ConcreteAbstractionImpB::ConcreteAbstractionImpB()
{

}
ConcreteAbstractionImpB::~ConcreteAbstractionImpB()
{

}
void ConcreteAbstractionImpB::Operation()
{
cout<<"ConcreteAbstractionImpB...."<<endl;
}
