游戏log的格式的优化

游戏log是非常关键的，对于追踪bug和查看一些信息，所以游戏里面是大量的log输出，sprintf的格式非常难用，而且对格式有较高的要求。
下面一种优化方案如下：

// MVC.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include <iostream>
#include <string>
#include <sstream>
using namespace std;

class EndLogOut{};
class LogOut
{
public:
    LogOut& operator<<(int a)
    {
        ss<<a;      
        return *this;
    }

    LogOut& operator<<(float a)
    {
        ss<<a;      
        return *this;
    }

    LogOut& operator<<(bool a)
    {
        ss<<a;      
        return *this;
    }

    LogOut& operator<<(char* a)
    {
        ss<<".."<<a<<"..";  
        return *this;
    }

    LogOut& operator<<(std::string a)
    {
        ss<<".."<<a<<"..";      
        return *this;
    }

    std::string operator<<(std::basic_ostream<char, char_traits<char> >& _Ostr)
    {
        ss>>logString;
        return logString;
    }

    std::string operator<<(EndLogOut)
    {
        ss>>logString;
        cout<<logString<<endl;
        return logString;
    }

    std::string GetString()
    {
        ss>>logString;
        return logString;
    }

private:
    stringstream ss;
    std::string logString;
    int type;
};

#define ELOGOUT LogOut()
int _tmain(int argc, _TCHAR* argv[])
{
    LogOut log;
    char* s = "ssss";
    std::string ss = "oooo";
    float ff = 1.09f;
    bool bb = true;
    log<<1<<"test"<<s<<ss<<ff<<bb;
    ELOGOUT<<1<<"test"<<s<<ss<<ff<<bb<<EndLogOut();
    //cout<<log.GetString()<<endl;
    return 0;
}
