17 class WorkLibrary from StepSelect inherits WorkLibrary from IFSelect
19 ---Purpose : Performs Read and Write a STEP File with a STEP Model
20 -- Following the protocols, Copy may be implemented or not
22 uses CString, Transient,
23 CheckIterator, InterfaceModel, Protocol from Interface,
24 Messenger from Message,
25 EntityIterator, CopyTool,
30 Create (copymode : Boolean = Standard_True)
31 returns mutable WorkLibrary from StepSelect;
32 ---Purpose : Creates a STEP WorkLibrary
33 -- <copymode> precises whether Copy is implemented or not
35 SetDumpLabel (me : mutable; mode : Integer);
36 ---Purpose : Selects a mode to dump entities
37 -- 0 (D) : prints numbers, then displays table number/label
38 -- 1 : prints labels, then displays table label/number
39 -- 2 : prints labels onky
41 ReadFile (me; name : CString;
42 model : out mutable InterfaceModel;
43 protocol : Protocol from Interface)
45 ---Purpose : Reads a STEP File and returns a STEP Model (into <mod>),
46 -- or lets <mod> "Null" in case of Error
47 -- Returns 0 if OK, 1 if Read Error, -1 if File not opened
49 WriteFile (me; ctx : in out ContextWrite) returns Boolean;
50 ---Purpose : Writes a File from a STEP Model
51 -- Returns False (and writes no file) if <ctx> does not bring a
55 original : InterfaceModel;
56 newmodel : mutable InterfaceModel;
57 list : EntityIterator;
59 returns Boolean is redefined;
60 ---Purpose : Performs the copy of entities from an original model to a new
61 -- one. Works according <copymode> :
62 -- if True, standard copy is run
63 -- else nothing is done and returned value is False
66 model : InterfaceModel;
67 protocol : Protocol from Interface;
69 S : Messenger from Message;
71 ---Purpose : Dumps an entity under STEP form, i.e. as a part of a Step file
72 -- Works with a StepDumper.
73 -- Level 0 just displays type; level 1 displays the entity itself
74 -- and level 2 displays the entity plus its shared ones (one
75 -- sub-level : immediately shared entities)
