Detailed Description

This package provides classes and methods to translate a transient DF into a persistent one and vice versa.

Driver

A driver is a tool used to translate a transient attribute into a persistent one and vice versa.

Relocation Table

A relocation table is a tool who provides services to relocate transient objects into persistent ones (or vice versa). It uses a map system to keep the sharing. This service is used by the drivers.

Driver Table

A driver table is an object building links between object types and object drivers. In the translation process, a driver table is asked to give a translation driver for each current object to be translated.
