class WorkLibrary from StepSelect inherits WorkLibrary from IFSelect
---Purpose : Performs Read and Write a STEP File with a STEP Model
-- Following the protocols, Copy may be implemented or not
uses CString, Transient,
CheckIterator, InterfaceModel, Protocol from Interface,
Messenger from Message,
EntityIterator, CopyTool,
ContextWrite
is
Create (copymode : Boolean = Standard_True)
returns mutable WorkLibrary from StepSelect;
---Purpose : Creates a STEP WorkLibrary
-- <copymode> precises whether Copy is implemented or not
SetDumpLabel (me : mutable; mode : Integer);
---Purpose : Selects a mode to dump entities
-- 0 (D) : prints numbers, then displays table number/label
-- 1 : prints labels, then displays table label/number
-- 2 : prints labels onky
ReadFile (me; name : CString;
model : out mutable InterfaceModel;
protocol : Protocol from Interface)
returns Integer;
---Purpose : Reads a STEP File and returns a STEP Model (into <mod>),
-- or lets <mod> "Null" in case of Error
-- Returns 0 if OK, 1 if Read Error, -1 if File not opened
WriteFile (me; ctx : in out ContextWrite) returns Boolean;
---Purpose : Writes a File from a STEP Model
-- Returns False (and writes no file) if <ctx> does not bring a
-- STEP Model
CopyModel (me;
original : InterfaceModel;
newmodel : mutable InterfaceModel;
list : EntityIterator;
TC : in out CopyTool)
returns Boolean is redefined;
---Purpose : Performs the copy of entities from an original model to a new
-- one. Works according <copymode> :
-- if True, standard copy is run
-- else nothing is done and returned value is False
DumpEntity (me;
model : InterfaceModel;
protocol : Protocol from Interface;
entity : Transient;
S : Messenger from Message;
level : Integer);
---Purpose : Dumps an entity under STEP form, i.e. as a part of a Step file
-- Works with a StepDumper.
-- Level 0 just displays type; level 1 displays the entity itself
-- and level 2 displays the entity plus its shared ones (one
-- sub-level : immediately shared entities)
