deferred generic class FileModifier from IFSelect
|
|
(Writer as any) -- according each Interface
|
|
inherits GeneralModifier
|
|
|
|
---Purpose : Allows to precise the frame work for File Modifiers able to
|
|
-- run with an Interface (such as STEP, VDA, IGES ...)
|
|
--
|
|
-- Remember that File Modifiers are activated by a WorkLibrary :
|
|
-- if they inherit from an instantiation of FileModifier with the
|
|
-- data from this Interface, this will be easier to do.
|
|
-- They are activated before sending the file, in the order
|
|
-- given by the ModielCopier.
|
|
--
|
|
-- For each Interface on which File Modifiers have to be defined,
|
|
-- The way to follow is firstly to instantiate FileModifier with
|
|
-- its specific data :
|
|
-- Model is the InterfaceModel specific to the considered norm
|
|
-- Writer is the Writer specific to the considered norm
|
|
-- Then to define the various classes which inherit from it and
|
|
-- define their method Perform
|
|
|
|
uses ContextWrite
|
|
|
|
is
|
|
|
|
Initialize;
|
|
---Purpose : Sets a File Modifier to keep the graph of dependences
|
|
-- unchanges (because it works on the model already produced)
|
|
|
|
Perform (me; ctx : in out ContextWrite; writer : in out Writer)
|
|
is deferred;
|
|
---Purpose : Perform the action specific to each class of File Modifier
|
|
-- <ctx> is the ContextWrite, which brings : the model, the
|
|
-- protocol, the file name, plus the object AppliedModifiers
|
|
-- (not used here) and the CheckList
|
|
-- Remark that the model has to be casted for specific access
|
|
--
|
|
-- <writer> is the Writer and is specific to each norm, on which
|
|
-- to act
