Re: [Boost-users] Boost serialization: is there a way to perform selective read

The problem with this solution is that it is time consuming, to open file for a key, i would like to use the boost serializeation to improve  time preformance. 
What is realy required is some mechanism, to identify an instance according to its key and only than read its data. Thus reading only the required instnace (accordig to its key) and not also the previous data at the file, someting like seek.
I hoped that "XML boost" can supply someting like that, but could not find how.
Thanks,

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.
