Serialize and deserialize objects in C ++ - mysql

Question

I'm new to C ++, I can not find a detailed example of how to serialize an object in binary so I can save it to the mysql server and then be deserialized.
The object looks like this:
class house{
public:
int houseNumber;
bool isEmpty;
Dweller *dweller;
};
class Dweller{
public:
int phoneNumber;
bool man;
Backpack backpack;
};
class Backpack{
public:
int item1;
int item2;
int item3;
int item4;
float weight;
bool empty;
};
I have to serialize the house object, which owns the other objects.

Answer 1

I was able to solve the problem using:
#include <boost/serialization/serialization.hpp>
#include <boost/serialization/vector.hpp>
See I used #include "boost/serialization/vector.hpp" because now the 'dweller' are in a vector to make things easier
Then the code stayed like this:
class house{
public:
int houseNumber;
bool isEmpty;
std::vector<Dweller> dweller;
private:
friend class boost::serialization::access;
template <class archive>
void serialize(archive &ar, const unsigned int version)
{
ar &houseNumber;
ar &isEmpty;
ar &dweller;
}
};
class Dweller{
public:
int phoneNumber;
bool man;
Backpack backpack;
private:
friend class boost::serialization::access;
template <class archive>
void serialize(archive &ar, const unsigned int version)
{
ar &phoneNumber;
ar &man;
ar &backpack;
}
};
class Backpack{
public:
int item1;
int item2;
int item3;
int item4;
float weight;
bool empty;
private:
friend class boost::serialization::access;
template <class archive>
void serialize(archive &ar, const unsigned int version)
{
ar &item1;
ar &item2;
ar &item3;
ar &item4;
ar &weight;
ar ∅
}
};
So to serialize I used:
#include <iostream>
#include <boost/archive/binary_oarchive.hpp>
#include <boost/archive/binary_iarchive.hpp>
#include <boost/serialization/serialization.hpp>
#include <sstream>
int main()
{
Backpack _backpack;
_backpack.item1 = 0;
_backpack.item1 = 1;
_backpack.item1 = 2;
_backpack.item1 = 3;
_backpack.item1 = 4;
_backpack.weight = 3.21;
_backpack.empty = false;
Dweller _dweller1;
_dweller.phoneNumber = 1234567;
_dweller.man = false;
_dweller.backpack = _backpack;
Dweller _dweller2;
_dweller.phoneNumber = 7654321;
_dweller.man = true;
_dweller.backpack = _backpack;
std::vector<Dweller> _dwellers;
_dwellers.push_back(_dweller1);
_dwellers.push_back(_dweller2);
house _house;
_house.houseNumber = 4;
_house.isEmpty = false;
_house.dweller = _dwellers;
/*Serializing*/
std::stringstream ss;
boost::archive::binary_oarchive oa(ss);
oa << _house;
/*Deserializing*/
boost::archive::binary_iarchive ia(ss);
house _house2;
ia >> _house2;
}
