Boost Serialization은 어떻게 C 객체 직렬화 및 역직렬화를 단순화할 수 있습니까?

#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>

class gps_position {
private:
    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive &amp; ar, const unsigned int version) {
        ar &amp; degrees;
        ar &amp; minutes;
        ar &amp; seconds;
    }
    int degrees;
    int minutes;
    float seconds;

public:
    gps_position(){};
    gps_position(int d, int m, float s) :
    degrees(d), minutes(m), seconds(s)
    {}
};

std::ofstream ofs("filename.dat", std::ios::binary);

// create class instance
const gps_position g(35, 59, 24.567f);

// save data to archive
{
    boost::archive::binary_oarchive oa(ofs);
    // write class instance to archive
    oa << g;
    // archive and stream closed when destructors are called
}

std::ifstream ifs("filename.dat", std::ios::binary);

// create class instance to store deserialized object
gps_position g_deserialized;

// read class instance from archive
{
    boost::archive::binary_iarchive ia(ifs);
    ia >> g_deserialized;
    // archive and stream closed when destructors are called
}
