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

A couple of hints:

a) constructor is called only when de-serializing a pointer.  So unless
you're doing this you won't see and constructor call.

b) When creating a new object in the course of de-serializing a pointer, the
function load_construct_data is callled.  This calls an in place new for the
default constructor.  By specializing this function for your particular
class, you can arrange to call a non-default constructor.
