如何使用 boost::serialization 以对象向量作为属性序列化对象

How to serialize object with vector of objects as attribute using boost::serialization

我正在尝试创建对象的基础,其中包含来自不同 class 的对象的属性向量。这是我的代码:

    #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;
};

错误,我得到的是:

c:\boost_1_57_0\boost\serialization\access.hpp(118):错误 C2039:序列化:不是 "std::vector>".

有人可以分享如何序列化该类型对象的经验吗?

要使代码可编译,必须执行以下操作:

  1. 包括 header 负责矢量序列化

    #include <boost/serialization/vector.hpp>
    
  2. serialize方法添加到form_mestoclass

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

Here为可编译代码
