Re: [Boost-users] Serialization of a complex data structure

3 May 2010

      I don't know if I understood correctly but I understood that the key
function of vector serialization is split_free. I did not understand how to
use this technique in the case of my example. Can you help me understand the
workings of the vector serialization so as to know how to extend it to
classes? What can i read to understand how to solve?

Thanks...

Marco.

Try looking inside boost/serialization/vector.hpp to see how it was done
for the STL containers.

Yes.
I did an example like this to learn how to serialize in the
"classical" way.
My problem is that i can't define a serialize method inside
Container, but i would serialize it anyway. How can i serialize the
Example strut entirely?
Do you understand my problem?

Robert, where can I find what you're talking about?
I don't know what you're trying to do so I'll take a guess.
Does this look like what you want to do?
struct Container {
    int m_container_member;
    ... // more members
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version){
        ar & m_container_member;
        ... // more members
    }
};
struct Example {
    friend class boost::serialization::access; // not really
necessary as all "struct" members are public
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version){
        ar & m_container;
    }
};
int main(int argc, char * argv[]){
    const Container c = ...
    std::fostream os("filename");
    boost::serialization::archive ar(os);
    ar & c;
}
Does that help any?
