I haven't yet worked with a serialization framework smart enough to consider constructor arguments. (I haven't yet worked with the Boost Serialization library, either; forgive me if this is already a solved problem.) Boost::serialization requires a constructor with no arguments.
That's not right I'm afraid. See the "Non-Default Constructors" part of the serialization library documentation for details.
This pertains to deserializing pointers to instances of classes with no default constructor. Is does not mean anything concerning deserialization of instances. Those need to be constructed before being deserialized to.
Oliver is correct -- serialization does not require default constructors for the types. It does require a constructed object prior to reading in the data. date_time had serialization code before it had default constructors for dates. To this day it doesn't depend on default constructors in the serialization code. Jeff
