deferred class Driver from TFunction inherits TShared from MMgt
|
|
|
|
---Purpose: This driver class provide services around function
|
|
-- execution. One instance of this class is built for
|
|
-- the whole session. The driver is bound to the
|
|
-- DriverGUID in the DriverTable class.
|
|
-- It allows you to create classes which inherit from
|
|
-- this abstract class.
|
|
-- These subclasses identify the various algorithms
|
|
-- which can be applied to the data contained in the
|
|
-- attributes of sub-labels of a model.
|
|
-- A single instance of this class and each of its
|
|
-- subclasses is built for the whole session.
