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.

class IGESReaderTool from IGESData inherits FileReaderTool
|
|
|
|
---Purpose : specific FileReaderTool for IGES
|
|
-- Parameters are accessed through specific objects, ParamReaders
|
|
|
|
uses Integer, Boolean, Transient,
|
|
Check, InterfaceModel, GeneralLib, ReaderLib, ParamList,
|
|
IGESReaderData, Protocol from IGESData, FileRecognizer,
|
|
IGESType, IGESEntity, DirPart, ReadStage, ParamReader
|
|
|
|
is
|
|
|
|
Create (reader : IGESReaderData; protocol : Protocol from IGESData)
|
|
returns IGESReaderTool;
|
|
---Purpose : creates IGESReaderTool to work with an IGESReaderData and an
|
|
-- IGES Protocol.
|
|
-- Actually, no Lib is used
|
|
|
|
-- -- General -- --
|
|
|
|
Prepare (me : in out; reco : FileRecognizer);
|
|
---Purpose : binds empty entities to records, works with the Protocol
|
|
-- (from IGESData) stored and later used
|
|
-- RQ : Actually, sets DNum into IGES Entities
|
|
-- Also loads the list of parameters for ParamReader
|
|
|
|
Recognize (me : in out; num : Integer;
|
|
ach : in out Check; ent : out Transient)
|
|
returns Boolean;
|
|
---Purpose : recognizes records by asking Protocol (on data of DirType)
|
|
|
|
-- Loading the IGESModel --
|
|
|
|
BeginRead (me : in out; amodel : InterfaceModel);
|
|
---Purpose : fills model's header, that is, its GlobalSection
|
|
|
|
AnalyseRecord (me : in out;
|
|
num : Integer; anent : Transient; acheck : in out Check)
|
|
returns Boolean;
|
|
---Purpose : fills an entity, given record no; works by calling ReadDirPart
|
|
-- then ReadParams (with help of a ParamReader), then if required
|
|
-- ReadProps and ReadAssocs, from IGESEntity
|
|
-- Returns True if no fail has been recorded
|
|
|
|
EndRead (me : in out; amodel : InterfaceModel) is redefined;
|
|
---Purpose : after reading entities, true line weights can be computed
|
|
|
|
-- For each IGESEntity --
|
|
|
|
ReadDir (me; ent : IGESEntity; IR : IGESReaderData;
|
|
DP : DirPart; ach : in out Check);
|
|
---Purpose : Reads directory part componants from file; DP is the litteral
|
|
-- directory part, IR detains entities referenced by DP
|
|
|
|
ReadOwnParams (me; ent : IGESEntity;
|
|
IR : IGESReaderData; PR : in out ParamReader);
|
|
---Purpose : Performs Reading of own Parameters for each IGESEntity
|
|
-- Works with the ReaderLib loaded with ReadWriteModules for IGES
|
|
-- In case of failure, tries UndefinedEntity from IGES
|
|
|
|
ReadProps (me; ent : IGESEntity; IR : IGESReaderData;
|
|
PR : in out ParamReader);
|
|
---Purpose : Reads Property List, if there is (if not, does nothing)
|
|
-- criterium is : current parameter of PR remains inside params
|
|
-- list, and Stage is "Own"
|
|
-- Current parameter must be a positive integer, which value
|
|
-- gives the length of the list; else, a Fail is produced (into
|
|
-- Check of PR) and reading process is stopped
|
|
|
|
ReadAssocs (me; ent : IGESEntity; IR : IGESReaderData;
|
|
PR : in out ParamReader);
|
|
---Purpose : Reads Associativity List, if there is (if not, does nothing)
|
|
-- criterium is : current parameter of PR remains inside params
|
|
-- list, and Stage is "Own"
|
|
-- Same conditions as above; in addition, no parameter must be
|
|
-- let after the list once read
|
|
-- Note that "Associated" entities are not declared "Shared"
