package MgtTopoDS
---Purpose: The package MgtTopoDS provides methods to store
-- and retrieve Topological Data Structure objects
-- from the Database.
--
-- The objects are translated between a transient
-- topology and a persitent topology.
--
-- * The TopoDS package describes the transient
-- topology.
--
-- * The PTopoDS package describes the persistent
-- topology.
--
-- As the topological data structure may be completed
-- by inheritance the MgtTopoDS package provides a
-- mechanism to support the translation of inherited
-- data structure. This mechanism is supported by the
-- TranslateTool class.
--
-- An error is raised if the TranslateTool does not
-- match with the DataStructure to translate. This
-- check is done with the type of the Model.
--
-- This package does not provides methods to
-- translate directly Shapes from TopoDS and PTopoDS
-- because the data structures are deferred. It
-- provides methods to support the implementation of
-- Translate methods in the inherited DataStructures.
--
-- In an inherited data structure the Translate
-- method must :
--
-- * Create a TranslateTool of the correct type.
--
-- * Call the Translate method of MgtTopoDS with this
-- Tool.
