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 StepReaderTool from StepData inherits FileReaderTool
|
|
|
|
---Purpose : Specific FileReaderTool for Step; works with FileReaderData
|
|
-- provides references evaluation, plus access to litteral data
|
|
-- and specific methods defined by FileReaderTool
|
|
-- Remarks : works with a ReaderLib to load Entities
|
|
|
|
uses Integer, Boolean, Transient,
|
|
InterfaceModel, Check, GeneralLib, ReaderLib,
|
|
StepReaderData, FileRecognizer, Protocol from StepData
|
|
|
|
is

|
|
|
-- -- File data storing and access (specific) -- --
|
|
|
|
Create (reader : StepReaderData; protocol : Protocol from StepData)
|
|
returns StepReaderTool;
|
|
---Purpose : creates StepReaderTool to work with a StepReaderData according
|
|
-- to a Step Protocol. Defines the ReaderLib at this time
|
|
|
|
-- -- setting empty entities before loading model -- --
|
|
|
|
Prepare (me : in out; optimize : Boolean = Standard_True);
|
|
---Purpose : Bounds empty entities to records, uses default Recognition
|
|
-- provided by ReaderLib and ReaderModule. Also calls computation
|
|
-- of references (SetEntityNumbers from StepReaderData)
|
|
-- Works only on data entities (skips header)
|
|
-- <optimize> given False allows to test some internal algorithms
|
|
-- which are normally avoided (see also StepReaderData)
|
|
|
|
Prepare (me : in out; reco : FileRecognizer;
|
|
optimize : Boolean = Standard_True);
|
|
---Purpose : Bounds empty entities to records, works with a specific
|
|
-- FileRecognizer, stored and later used in Recognize
|
|
-- Works only on data entities (skips header)
|
|
-- <optimize : same as above
|
|
|
|
Recognize (me : in out; num : Integer;
|
|
ach : in out Check; ent : out Transient)
|
|
returns Boolean;
|
|
---Purpose : recognizes records, by asking either ReaderLib (default) or
|
|
-- FileRecognizer (if defined) to do so. <ach> is to call
|
|
-- RecognizeByLib
|
|
|
|
-- -- managing Header -- --
|
|
-- Header is defined as a list of StepEntities (without ident)
|
|
|
|
PrepareHeader (me : in out; reco : FileRecognizer);
|
|
---Purpose : bounds empty entities and sub-lists to header records
|
|
-- works like Prepare + SetEntityNumbers, but for header
|
|
-- (N.B.: in Header, no Ident and no reference)
|
|
-- FileRecognizer is to specify Entities which are allowed to be
|
|
-- defined in the Header (not every type can be)
|
|
|
|
-- -- loading entities into the model -- --
|
|
|
|
BeginRead (me : in out; amodel : InterfaceModel);
|
|
---Purpose : fills model's header; that is, gives to it Header entities
|
|
-- and commands their loading. Also fills StepModel's Global
|
|
-- Check from StepReaderData's GlobalCheck
|
|
|
|
AnalyseRecord (me : in out;
|
|
num : Integer; anent : Transient; acheck : in out Check)
|
|
returns Boolean;
|
|
---Purpose : fills an entity, given record no; works by using a ReaderLib
|
|
-- to load each entity, which must be a Transient
|
|
-- Actually, returned value is True if no fail, False else
|
|
|
|
EndRead (me : in out; amodel : InterfaceModel) is redefined;
|
|
---Purpose : Ends file reading after reading all the entities
|
|
-- Here, it binds in the model, Idents to Entities (for checks)
