Hello, While using the latest release of boost, I've encountered a few questions concerning the usage of the serialization library with objects without default constructors. Here they are: 1-) How can we construct an instance of a serialized object that doesn't have a default constructor? The only option I've figured out is to normally construct an object with bogus values, then unserialize the real values while reading from the archive. Example: X(0) val; // 0 being some bogus value. inputStream >> val; // Overwrites all values within val; Is this the correct way to do things? 2-) How should we split the serialization between the class' serialize member versus load/save_construct_data? My observations show that when un/serializing objects directly like shown above, load/save_construct_data aren't needed, so the serialize member has to handle everything. When serializing a vector<X>, load/save_construct_data does get called, so we have to un/serialize some members in those functions as well. At first glance, it seems some members will have to be un/serialized for the second time within load/save_construct_data. Is that correct? For a class to be correctly un/serializable for all cases, load/save_construct_data must un/serialize members that are already taken care of in the serialize member? Thanks!
