[分享]网络编程中的小技巧，STL中map与hash_map的选择,该怎么解决

class TPTCPServer : public ITPObject
{
public:
    TPTCPServer(ITPListener* tcpserverapp, int engineId = 0);
    TPTCPServer(int engineId, ITPListener* listener, CNewMutex* mutex);
    virtual ~TPTCPServer();

public: 
    virtual int CloseClient(int id);

    virtual int Close();
    
    virtual int Listen(char* ip, int port);
    
    virtual int Send(int id, char *pBuf, unsigned int iBufLen);

//注意这个接口。
    virtual int Heartbeat();

    virtual Queue_List* GetSendQueue(int connId);

    virtual int SetMaxDataQueueLength(int maxDataQueueLength);

protected:
    int sendInside(int id, char* pBuf, unsigned int iBufLen);
    int closeInside();
    virtual int clearSendBuffer();
    virtual int fillFds(int& maxfd, fd_set& readfds, fd_set& writefds);
    virtual int dealFDResult(int& fds,fd_set& readfds, fd_set& writefds,bool& fdsChange);

protected:
    int    _maxDataQueueLength;

protected:
    void addPendingCloseClient(int id);
    int dealPendingCloseClients();
    void pendingCloseClient(int id);
    std::deque<int> _pendingCloseClients;
    AX_Thread_Mutex _pendingCloseClientsMutex;
};
