[Boost-users] Serialization : Deserializing members not present in archive

Hey,

  I have a class with a few data members that is serializable. Note that, I
already have an archive ( test.txt ). Now, I want to serialize a couple more
members. I went ahead and added the new members to my serialize functions.
When I read from the archive ( test.txt ) , I get an exception. This is
understandable, because the archive doesn't have the new members that I'm
trying to read out.

  My question is, is there a way to check for the existence of a member
before deserializing an object from the archive ?

Thanks in advance,
Sandeep.
