deferred class CopyControl from Interface inherits TShared
|
|
|
|
---Purpose : This deferred class describes the services required by
|
|
-- CopyTool to work. They are very simple and correspond
|
|
-- basically to the management of an indexed map.
|
|
-- But they can be provided by various classes which can
|
|
-- control a Transfer. Each Starting Entity have at most
|
|
-- one Result (Mapping one-one)
|
|

---Purpose : Searches for the Result bound to a Startingf Entity identified
|
|
-- by its Number.
|
|
-- If Found, returns True and fills <res>
|
|
-- Else, returns False and nullifies <res>
