Mediator 中介者模式

中介者模式主要用于对象之间的通信

Mediator.h文件：

#include "stdafx.h"
#include 
#include 
#include 
#include 
#include 
#include using namespace boost;typedef std::string ColleageAData;
typedef long ColleageBData;class Mediator;class Colleage
{
protected:shared_ptr _m_mediator;
};class ColleageA : public Colleage
{
public:ColleageA(){m_data = "asdf";m_recvBData = 0;};void setMediator(shared_ptr mediator);void sendDataToColleageB(ColleageAData data);void setData(ColleageAData data){m_data = data;}ColleageAData getData(){return m_data;}void showInfo(){std::cout << "A:" << m_data << "B:" << m_recvBData << std::endl;}
public:ColleageBData m_recvBData;ColleageAData m_data;
};class ColleageB : public Colleage
{
public:ColleageB(){m_data = 1113;m_recvAData = "null";}void setMediator(shared_ptr mediator);void sendDataToColleageA(ColleageBData data);void setData(ColleageBData data){m_data = data;}ColleageBData getData(){return m_data;}void showInfo(){std::cout << "B:" << m_data << "A:" << m_recvAData << std::endl;}
public:ColleageAData m_recvAData;ColleageBData m_data;
};class Mediator
{
public:Mediator(){}virtual ~Mediator(){}Mediator(shared_ptr a,shared_ptr b){_m_A = a;_m_B = b;}void AsendtoB(ColleageAData dataA);void BsendtoA(ColleageBData dataB);void setA(shared_ptr a){_m_A = a;}void setB(shared_ptr b){_m_B = b;}protected://该中介者用于处理A和Bshared_ptr _m_A;shared_ptr _m_B;
