c++桥接模式，中介者模式应用实现状态跳转

上图为例，按上述两种方式实现的模式跳转，如果在原先的三种模式之间再增加多一种模式，就会引起每个模式都会要求改变，并且逻辑混乱，因此更改模式为桥接+中介者访问，将抽象和实现分离，实现之间采用中介者实现模式之间的通信，或者在实现中去管理每个模式之间的通信。方便后续扩展：

class MaWorkState;
typedef enum _childMastate {RUN = 0,STOP,RUNNING,STATE_QTY,
}childMastate;
typedef bool(MaWorkState::* Statefunc)(void);typedef std::function<bool(void)> pcb;
class StateSwitching {
public:StateSwitching() {};virtual void DoSate(){while (!m_pcontext.empty()){m_deque.at(m_pcontext.at(0));m_pcontext.pop_front();}}template<typename Ty>void PushEvent(Ty ev){m_pcontext.push_back(ev);}
protected:std::deque<int> m_pcontext;std::deque<pcb> m_deque;ModuleNormalOutput* m_ModuleNormalOutput;DdsWaveHandle* m_pDds;
};/*  
class mediator;class StateSwitching {
public:StateSwitching() {};virtual void GenMediator(mediator* media) { m_mediator = media; };virtual bool ReleaseMode() {};   //这样：不管增加多少模式，都只是实现自己的两个接口就可以，但必须将模式之间的交互隔离，模式之间不产生联系,如果出现关联，抽线一层(使用一个中介者实现关联)virtual bool CtrlMode() {};
