Redundant keyword 'mutable' removed in CDL files. In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed. Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.

deferred class ReadWriteModule from IGESData
|
|
inherits ReaderModule from Interface
|
|
|
|
---Purpose : Defines basic File Access Module, under the control of
|
|
-- IGESReaderTool for Reading and IGESWriter for Writing :
|
|
-- Specific actions concern : Read and Write Own Parameters of
|
|
-- an IGESEntity.
|
|
-- The common parts (Directory Entry, Lists of Associativities
|
|
-- and Properties) are processed by IGESReaderTool & IGESWriter
|
|
--
|
|
-- Each sub-class of ReadWriteModule is used in conjunction with
|
|
-- a sub-class of Protocol from IGESData and processes several
|
|
-- types of IGESEntity (typically, them of a package) :
|
|
-- The Protocol gives a unique positive integer Case Number for
|
|
-- each type of IGESEntity it recognizes, the corresponding
|
|
-- ReadWriteModule processes an Entity by using the Case Number
|
|
-- to known what is to do
|
|
-- On Reading, the general service NewVoid is used to create an
|
|
-- IGES Entity the first time
|
|
--
|
|
-- Warning : Works with an IGESReaderData which stores "DE parts" of Items
|
|

|
raises DomainError
|
|
|
|
is
|
|
|
|
CaseNum (me; data : FileReaderData; num : Integer) returns Integer;
|
|
---Purpose : Translates the Type of record <num> in <data> to a positive
|
|
-- Case Number, or 0 if failed.
|
|
-- Works with IGESReaderData which provides Type & Form Numbers,
|
|
-- and calls CaseIGES (see below)
|
|
|
|
CaseIGES (me; typenum, formnum : Integer) returns Integer is deferred;
|
|
---Purpose : Defines Case Numbers corresponding to the Entity Types taken
|
|
-- into account by a sub-class of ReadWriteModule (hence, each
|
|
-- sub-class of ReadWriteModule has to redefine this method)
|
|
-- Called by CaseNum. Its result will then be used to call
|
|
-- Read, etc ...

ReadOwnParams (me; CN : Integer; ent : IGESEntity;
|
|
IR : IGESReaderData; PR : in out ParamReader)
|
|
raises DomainError is deferred;
|
|
---Purpose : Reads own parameters from file for an Entity; <PR> gives
|
|
-- access to them, <IR> detains parameter types and values
|
|
-- For each class, there must be a specific action provided
|
|
-- Note that Properties and Associativities Lists are Read by
|
|
-- specific methods (see below), they are called under control
|
|
-- of reading process (only one call) according Stage recorded
|
|
-- in ParamReader
|
|
|
|
|
|
WriteOwnParams (me; CN : Integer; ent : IGESEntity;
|
|
IW : in out IGESWriter)
|
|
is deferred;
|
|
---Purpose : Writes own parameters to IGESWriter; defined for each class
|
|
-- (to be redefined for other IGES ReadWriteModules)
|
|
-- Warning : Properties and Associativities are directly managed by
|
|
-- WriteIGES, must not be sent by this method
