boost::variant serialization is implemented in the next version (1.32) that might work. If you want to make an implementation of boost::any serialization that might work too. In fact I think the way to go about this is to decide which of the above suits you best and if it doesn't implement serialization, do it yourself! Robert Ramey Sean Kelly wrote:

Dear All,

I'm trying to figure out if something like the below is possible with the serialization library. The idea is to serialize a heterogeneous sequence using shared_pointer<void>.

thanks for any help

Sean

void hetero_sequence() { // create and open a character archive for output std::ofstream ofs("dictionary.pickle"); boost::archive::text_oarchive oa(ofs);

std::deque<boost::shared_ptr<void> > sequence; sequence.push_back(boost::shared_ptr<string>(new string("random string"))); sequence.push_back(boost::shared_ptr<double>(new double(3.1415627))); sequence.push_back(boost::shared_ptr<bool>(new bool(false)));

// write class instance to archive oa << sequence; // close archive ofs.close(); }
