 Default destructor.

virtual bool Write (Engine& archive) const
 This method is used to write to the Persistence::Engine It is not equivalent to the << operator as it writes only the data and not the object type etc.

virtual bool Read (Engine& archive)
 This method is used to read from a Persistence::Engine It is not equivalent to the >> operator as it does no typesafety or anything.


Detailed Description

BaseObject Base class for classes that will be persistent.

This object is the base for all Persistent data which is not natively serialised by the Persistence::Engine

It registers itself with the Persistence::TypeManager using a global constructor function. A matching deregister call is made in a global destructor, to allow DLL's to use the Persistence::Engine in a main executable.
