代码片段--参数相同函数调用机制

1，定义函数指针

typedef void (CAppProtocol::*PParse)(const tagClientInfo &clientinfo);

typedef void (CAppProtocol::*PResult)(int result, std::vector<tagProperty> TaskProperty);

2，定义map变量

std::map<CString, PParse> _mapParseProtocol;

std::map<int, PResult> _mapTaskResult;

3，添加具体处理函数

void CAppProtocol::CR_PhoneLogin(int result, std::vector<tagProperty> TaskProperty)

{

......

}

void CAppProtocol::CR_PhoneLogout(int result, std::vector<tagProperty> TaskProperty)

{

........

}

4，为map变量赋值

_mapParseProtocol.insert(std::pair<CString,PParse>(Pr_PhoneLogin, &CAppProtocol::CC_PhoneLogin));

_mapParseProtocol.insert(std::pair<CString,PParse>(Pr_PhoneLogout, &CAppProtocol::CC_PhoneLogout));

5，定义解析函数，只需要传递命令名称和函数参数

void CAppProtocol::ExeParse(CString command, const tagClientInfo &clientinfo)

{

if (_mapParseProtocol.find(command) != _mapParseProtocol.end())

{

PParse pFunc = _mapParseProtocol[command];

return (this->*pFunc)(nodeContent, clientinfo);

}

}

void CAppProtocol::TaskResult(int taskName, int result, std::vector<tagProperty> TaskProperty)

{

if (_mapTaskResult.find(taskName) != _mapTaskResult.end())

{

PResult pFunc = _mapTaskResult[taskName];

return (this->*pFunc)(result, TaskProperty);

}

}
