How can I serialize an std::vector with boost::serialization?

Question

class workflow {

private:
friend class boost::serialization::access;

template
void serialize(Archive & ar, const unsigned int version)
{
  ar          


        

Answer 1

In case someone will ever need to write explicit 'serialize' method without any includes of boost headers (for abstract purposes, etc):

std::vector dataVec;
int size; //you have explicitly add vector size

template 
void serialize(Archive &ar, const unsigned int version)
{
    if(Archive::is_loading::value) {
        ar & size;
        for(int i = 0; i < size; i++) {
            Data dat;
            ar & dat;
            dataVec.push_back(dat);
        }
    } else {
        size = dataVec.size();
        ar & size;
        for(int i = 0; i < size; i++) {
            ar & dataVec[i];
        }
    }
}
