Engine.

This class constructs on a standard C++ STL stream and then operates in the mode specified. The stream passed into the constructor must be a binary mode to function properly.

stream serialization of persistent classes.

These are the modes the Persistence::Engine can work in.

Enumerator

Constructs a Persistence::Engine with the specified stream in the given mode. The stream must be initialised properly prior to this call or problems will ensue. If built using zlib compress can be used to enable compression

This says there are more objects to deserialize.

void ost::Engine::read (BaseObject & object)

reads a BaseObject into a reference overwriting the object.

void ost::Engine::read (BaseObject *& object)
