17 | class Reader from IGESToBRep |
18 | |
19 | ---Purpose : A simple way to read geometric IGES data. |
20 | -- Encapsulates reading file and calling transfer tools |
21 | |
22 | uses |
23 | IGESModel from IGESData, |
24 | ShareFlags from Interface, |
25 | TransientProcess from Transfer, |
26 | Shape from TopoDS, |
27 | SequenceOfShape from TopTools, |
28 | Actor from IGESToBRep |
29 | |
30 | is |
31 | |
32 | Create returns Reader; |
33 | ---Purpose : Creates a Reader |
34 | |
35 | LoadFile (me : in out; filename : CString) returns Integer; |
36 | ---Purpose : Loads a Model from a file.Returns 0 if success. |
37 | -- returns 1 if the file could not be opened, |
38 | -- returns -1 if an error occurred while the file was being loaded. |
39 | |
40 | SetModel (me : in out; model : IGESModel); |
41 | ---Purpose : Specifies a Model to work on |
42 | -- Also clears the result and Done status, sets TransientProcess |
43 | |
44 | Model (me) returns IGESModel; |
45 | ---Purpose : Returns the Model to be worked on. |
46 | |
6e33d3ce |
47 | SetTransientProcess (me : in out; TP : TransientProcess); |
7fd59977 |
48 | ---Purpose : Allows to set an already defined TransientProcess |
49 | -- (to be called after LoadFile or SetModel) |
50 | |
51 | TransientProcess (me) returns TransientProcess; |
52 | ---Purpose : Returns the TransientProcess |
53 | |
54 | Actor (me) returns Actor from IGESToBRep; |
55 | ---Purpose : Returns "theActor" |
56 | |
57 | Clear (me : in out); |
58 | ---Purpose : Clears the results between two translation operations. |
59 | |
60 | Check (me; withprint : Boolean) returns Boolean; |
61 | ---Purpose : Checks the IGES file that was |
62 | -- loaded into memory. Displays error messages in the default |
63 | -- message file if withprint is true. Returns True if no fail |
64 | -- message was found and False if there was at least one fail message. |
65 | |
66 | TransferRoots (me : in out; onlyvisible : Boolean = Standard_True); |
67 | ---Purpose : Translates root entities in an |
68 | -- IGES file. Standard_True is the default value and means that only |
69 | -- visible root entities are translated. Standard_False |
70 | -- translates all of the roots (visible and invisible). |
71 | |
72 | Transfer (me : in out; num : Integer) returns Boolean; |
73 | ---Purpose : Transfers an Entity given its rank in the Model (Root or not) |
74 | -- Returns True if it is recognized as Geom-Topol. |
75 | -- (But it can have failed : see IsDone) |
76 | |
77 | IsDone (me) returns Boolean; |
78 | ---Purpose : Returns True if the LAST Transfer/TransferRoots was a success |
79 | |
80 | UsedTolerance (me) returns Real; |
81 | ---Purpose : Returns the Tolerance which has been actually used, converted |
82 | -- in millimeters |
83 | -- (either that from File or that from Session, according the mode) |
84 | |
85 | NbShapes (me) returns Integer; |
86 | ---Purpose : Returns the number of shapes produced by the translation. |
87 | |
88 | Shape (me; num : Integer = 1) returns Shape from TopoDS; |
89 | ---Purpose : Returns the num the resulting shape in a translation operation. |
90 | |
91 | OneShape (me) returns Shape from TopoDS; |
92 | ---Purpose : Returns all of the results in a |
93 | -- single shape which is: |
94 | -- - a null shape if there are no results, |
95 | -- - a shape if there is one result, |
96 | -- - a compound containing the resulting shapes if there are several. |
