Boost serialization: is there a way to perform selective read
Hey, I would like to know whether there is a way to preform selective read using Boost serialization, thus reading serialized instance with its id/key. The implementation that i know is saving instances to a file and then loading them all according to the saving order. Is there a way to read only one selected instance from the file. Thanks, -Ariella

How about serializing objects separately? I mean instead of saving a object and its children objects into a big file, simply saving them into different files.

You'd have to role your own to do this. It wouldn't be THAT hard if you derived fom xml_iarchive. But it wouldn't trivial either.

one file can contain concatonated archives. Robert Ramey
