[Boost-users] Serialization -- Which constructor is called?

In debugging a problem, I put breakpoints on the default and copy constructor along with the operator=. When de-serializing the class, none of the breakpoints were hit. I've searched through the documentation and old posts and can't seem to find any reference to which constructor is called from the serialization class. Could someone enlighten me on this? I'm sure it's covered somewhere, but I've somehow missed it. Thanks, Eric Boost 1.32 under Linux
