Boost serialization stamp?

when you try to se开发者_如何学JAVArialize object data why do get 22 serialization::archive 7 in your serialized data? how do you get rid of it?

A bit late perhaps, but I was looking for the same thing so here goes =)

You should take a look at the no_header flag documented here and used like this:

using namespace boost::archive;

std::stringstream stream;
text_oarchive archive(stream, no_header);
archive << object;

I'm assuming text archives here judging from your question but the same works for the other archive types.

Obviously one should consider carefully before using this since the self-documenting property of the archive is largely lost for a modest saving in space...
