如何使用boost :: serialization将带有对象向量的对象序列化为属性

Question

I'm trying to create base of objects, which contains as attribute vector of object from different class. Here's my code:

    #include <iostream>
    #include <string>
    #include <vector>
    #include <fstream>
    #include <boost/archive/binary_oarchive.hpp>
    #include <boost/archive/binary_iarchive.hpp>

    using namespace std;

    class form_mesto
    {
    public:
        string mesto;
        int year;
        int mounth;
        int day;
        bool visit = false;
        form_mesto(string a_mesto)
        {
            mesto = a_mesto;
        }
    };

    class Place
    {
    private:
        friend class boost::serialization::access;
        template<class Archieve>
        void serialize(Archieve&ar, const unsigned int version)
        {
            ar& mestа;
            ar& person;
        }
    public:
        string person;
        vector<form_mesto> mestа;

        Place(string a_person)
        {
            person = a_person;
        }

        void add_place(form_mesto a_mesto)
        {
            mestа.push_back(a_mesto);
        }
    };

int main()
{
    string input_in_form = "London";
    string input_in_Place = "Eugene";
    form_mesto z = form_mesto(input_in_form);
    Place x = Place(input_in_Place);
    x.add_place(z);
    std::ofstream ofs("save.dat", std::ios::binary);
    boost::archive::binary_oarchive oa(ofs);
    oa<<x;
};

Error, which i get is:

c:\\boost_1_57_0\\boost\\serialization\\access.hpp(118): error C2039: serialize: is not a member of "std::vector>".

Can somebody share experience of how to serialize that type of objects?

Answer 1

To make the code compilable, one has to do the following:

1. to include the header responsible for vector serialization

    #include <boost/serialization/vector.hpp> 

2. to add the serialize method to the form_mesto class

    class form_mesto { private: friend class boost::serialization::access; template<class Archieve> void serialize(Archieve&ar, const unsigned int version) { // ... } // ... }; 

Here is the compilable code.
