class Reader from STEPCAFControl
-- inherits Reader from STEPControl
---Purpose: Provides a tool to read STEP file and put it into
-- DECAF document. Besides transfer of shapes (including
-- assemblies) provided by STEPControl, supports also
-- colors and part names
--
-- This reader supports reading files with external references
-- i.e. multifile reading
-- It behaves as usual Reader (from STEPControl) for the main
-- file (e.g. if it is single file)
-- Results of reading other files can be accessed by name of the
-- file or by iterating on a readers

is
Create returns Reader;
---Purpose: Creates a reader with an empty
-- STEP model and sets ColorMode, LayerMode, NameMode and
-- PropsMode to Standard_True.
Create (WS : mutable WorkSession from XSControl;
scratch : Boolean = Standard_True) returns Reader;
---Purpose: Creates a reader tool and attaches it to an already existing Session
-- Clears the session if it was not yet set for STEP
Init (me: in out; WS : mutable WorkSession from XSControl;
scratch : Boolean = Standard_True);
---Purpose: Clears the internal data structures and attaches to a new session
-- Clears the session if it was not yet set for STEP
ReadFile (me : in out; filename : CString)
returns ReturnStatus from IFSelect;
---Purpose: Loads a file and returns the read status
-- Provided for use like single-file reader
NbRootsForTransfer (me: in out) returns Integer;
---Purpose: Returns number of roots recognized for transfer
-- Shortcut for Reader().NbRootsForTransfer()
TransferOneRoot (me: in out; num: Integer; doc: in out Document from TDocStd)
returns Boolean;
---Purpose: Translates currently loaded STEP file into the document
-- Returns True if succeeded, and False in case of fail
-- Provided for use like single-file reader
Transfer (me: in out; doc: in out Document from TDocStd)
returns Boolean;
---Purpose: Translates currently loaded STEP file into the document
-- Returns True if succeeded, and False in case of fail
-- Provided for use like single-file reader
Perform (me: in out; filename: AsciiString from TCollection;
doc: in out Document from TDocStd) returns Boolean;
Perform (me: in out; filename: CString; doc: in out Document from TDocStd)
returns Boolean;
---Purpose: Translate STEP file given by filename into the document
-- Return True if succeeded, and False in case of fail
---Scope: Access to fields
ExternFiles (me) returns DictionaryOfExternFile from STEPCAFControl;
---Purpose: Returns data on external files
-- Returns Null handle if no external files are read
---C++: return const &
ExternFile (me; name: CString; ef: out ExternFile from STEPCAFControl)
returns Boolean;
---Purpose: Returns data on external file by its name
-- Returns False if no external file with given name is read
ChangeReader (me: in out) returns Reader from STEPControl;
---Purpose: Returns basic reader
---C++: return &
Reader (me) returns Reader from STEPControl;
---Purpose: Returns basic reader as const
---C++: return const &
---Scope: Internal methods
Transfer (me: in out; rd: in out Reader from STEPControl;
num: Integer;
doc: in out Document from TDocStd;
Lseq: out LabelSequence from TDF;
asOne: Boolean = Standard_False)
returns Boolean is protected;
---Purpose: Translates STEP file already loaded into the reader
-- into the document
-- If num==0, translates all roots, else only root number num
-- Returns True if succeeded, and False in case of fail
-- If asOne is True, in case of multiple results composes
-- them into assembly. Fills sequence of produced labels

ShapePDMap: DataMapOfShapePD from STEPCAFControl;
PDFileMap : DataMapOfPDExternFile from STEPCAFControl;
ShapeLabelMap: in out DataMapOfShapeLabel from XCAFDoc)
returns Label from TDF is protected;
---Purpose: Add a shape to a document
-- Depending on a case, this shape can be added as one, or
-- as assembly, or (in case if it is associated with external
-- reference) taken as that referred shape
ReadExternFile (me: in out; file, fullpath: CString; doc: in out Document from TDocStd)
returns ExternFile from STEPCAFControl is protected;
---Purpose: Reads (or if returns already read) extern file with
-- given name
