不能设置ostringstream对象的streambuf

我想在我的程序中包含一些std::ostringstream对象，用于日志记录和错误报告。根据编译时给出的设置，日志和错误流要么收集它们各自的数据(要保存或其他)，要么将它们重定向到std::cout和std::cerr(用于调试目的)。据我所知，从我所看到的引用(和这里)，std::ostringstream对象继承了rdbuf()方法，我应该能够在流对象上调用rdbuf()方法，作为参数传递一个指向std::streambuf的指针以与流关联。

然而，当我尝试编译时，我收到一个没有匹配函数调用的错误，rdbuf()方法没有任何参数被列为候选。

我从g++ (Ubuntu 12.04 x86_64上的4.6.3)得到的错误:

<>之前sigma@SigmaSys:~/Scripts/http/test$ g++ test。Cc -c -o测试测试。cc:在构造函数' Logger::Logger() '中:测试。Cc:23:43:错误:没有匹配的函数调用' std::basic_ostringstream::rdbuf(std::basic_streambuf*) '测试。抄送:23:43:备注:候选人为:/usr/include/c++/4.6/sstream:449:7: note: std::basic_ostringstream::__stringbuf_type* std::basic_ostringstream::rdbuf() const [with _CharT = char， _Traits = std::char_traits， _Alloc = std::allocator, std::basic_ostringstream::__stringbuf_type = std:: basic_stringbuf_type = std::basic_stringbuf]/usr/include/c++/4.6/sstream:449:7:注意:候选人期望0个参数，提供1个之前

以下是源代码和头文件的精简版本:

http_utils.h

#include <string>
#include <sstream>
#include <streambuf>
#define HTTP_DEBUG_MODE 1

class Logger {
    private:
        static std::ostringstream errOut;
        static std::ostringstream logOut;
        static std::streambuf* cerrStreamBuffBackup;
        static std::streambuf* coutStreamBuffBackup;
        static std::streambuf* errOutStreamBuffBackup;
        static std::streambuf* logOutStreamBuffBackup;
    public:
        Logger();
        ~Logger();
};

http_utils。cc

#include "test.h"
#include <string>
#include <iostream>
#include <sstream>
#include <streambuf>

std::ostringstream Logger::errOut;
std::ostringstream Logger::logOut;
std::streambuf* Logger::cerrStreamBuffBackup = NULL;
std::streambuf* Logger::coutStreamBuffBackup = NULL;
std::streambuf* Logger::errOutStreamBuffBackup = NULL;
std::streambuf* Logger::logOutStreamBuffBackup = NULL;

Logger::Logger() {
    if (HTTP_DEBUG_MODE) {//Redirect logging/error to stdout/stderr
        Logger::errOutStreamBuffBackup = Logger::errOut.rdbuf();
        Logger::logOutStreamBuffBackup = Logger::logOut.rdbuf();
        Logger::errOut.rdbuf( std::cerr.rdbuf() );
        Logger::logOut.rdbuf( std::cout.rdbuf() );
    } else {//Redirect stdout/stderr to custom logging/error functionality
        cerrStreamBuffBackup = std::cerr.rdbuf();
        coutStreamBuffBackup = std::cout.rdbuf();
        std::cerr.rdbuf( errOut.rdbuf() );
        std::cout.rdbuf( logOut.rdbuf() );
    }
}
Logger::~Logger() {
    if (HTTP_DEBUG_MODE) {
    } else {//Restore stdout/stderr streambuf
        std::cerr.rdbuf( Logger::cerrStreamBuffBackup );
        std::cout.rdbuf( Logger::coutStreamBuffBackup );
    }
}

如果有人能帮我解决这个问题，或者给我一个替代方法的建议，我将不胜感激。
