boost::serialization 拆分serialize函数 - c++编程基础

er_; std::string grade_; }; 这个函数是intrusive的，我们也可以用一种non-intrusive：

class student_info
{
public:
	//...
private:
	template
   
    
	friend void serialize(Archive& ar, student_info &sdinfo, const unsigned int file_version);
private:
	std::string name_;
	std::string number_;
	std::string grade_;
};

再类外面实现 serialize 函数：

template
   
    
void serialize(Archive& ar, student_info &sdinfo, const unsigned int file_version)
{
	ar & BOOST_SERIALIZATION_NVP(sdinfo.name_);
	ar & BOOST_SERIALIZATION_NVP(sdinfo.number_);
	ar & BOOST_SERIALIZATION_NVP(sdinfo.grade_);
}

这样就ok了。

boost::serialization 拆分serialize函数(二)

class student_info { public: //... private: template friend void serialize(Archive& ar, student_info &sdinfo, const unsigned int file_version); private: std::string name_; std::string number_; std::string grade_; }; 再类外面实现 serialize 函数：

template void serialize(Archive& ar, student_info &sdinfo, const unsigned int file_version) { ar & BOOST_SERIALIZATION_NVP(sdinfo.name_); ar & BOOST_SERIALIZATION_NVP(sdinfo.number_); ar & BOOST_SERIALIZATION_NVP(sdinfo.grade_); } 这样就ok了。 (adsbygoogle = window.adsbygoogle || []).push({});

class student_info { public: //... private: template friend void serialize(Archive& ar, student_info &sdinfo, const unsigned int file_version); private: std::string name_; std::string number_; std::string grade_; };
再类外面实现 serialize 函数：

template void serialize(Archive& ar, student_info &sdinfo, const unsigned int file_version) { ar & BOOST_SERIALIZATION_NVP(sdinfo.name_); ar & BOOST_SERIALIZATION_NVP(sdinfo.number_); ar & BOOST_SERIALIZATION_NVP(sdinfo.grade_); }
这样就ok了。
