8 | class Loop from BRepAlgo |
9 | |
10 | ---Purpose: Builds the loops from a set of edges on a face. |
11 | |
12 | uses |
13 | |
14 | Face from TopoDS, |
15 | Edge from TopoDS, |
16 | ListOfShape from TopTools, |
17 | DataMapOfShapeListOfShape from TopTools, |
18 | DataMapOfShapeShape from TopTools |
19 | |
20 | is |
21 | |
22 | Create; |
23 | |
24 | Init (me : in out; F : Face from TopoDS) |
25 | ---Purpose: Init with <F> the set of edges must have |
26 | -- pcurves on <F>. |
27 | is static; |
28 | |
29 | AddEdge (me : in out; E : in out Edge from TopoDS; |
30 | LV : ListOfShape from TopTools) |
31 | ---Purpose: Add E with <LV>. <E> will be copied and trim |
32 | -- by vertices in <LV>. |
33 | is static; |
34 | |
35 | AddConstEdge (me : in out; E : Edge from TopoDS) |
36 | ---Purpose: Add <E> as const edge, E can be in the result. |
37 | is static; |
38 | |
39 | AddConstEdges (me : in out; LE : ListOfShape from TopTools) |
40 | ---Purpose: Add <LE> as a set of const edges. |
41 | is static; |
42 | |
43 | Perform(me : in out) |
44 | ---Purpose: Make loops. |
45 | is static; |
46 | |
47 | CutEdge(me; |
48 | E : Edge from TopoDS; |
49 | VonE : ListOfShape from TopTools; |
50 | NE : in out ListOfShape from TopTools) |
51 | ---Purpose: Cut the edge <E> in several edges <NE> on the |
52 | -- vertices<VonE>. |
53 | is static; |
54 | |
55 | NewWires (me) |
56 | ---Purpose: Returns the list of wires performed. |
57 | -- can be an empty list. |
58 | ---C++: return const & |
59 | returns ListOfShape from TopTools; |
60 | |
61 | WiresToFaces (me : in out) |
62 | ---Purpose: Build faces from the wires result. |
63 | is static; |
64 | |
65 | NewFaces (me) |
66 | ---Purpose: Returns the list of faces. |
67 | -- Warning: The method <WiresToFaces> as to be called before. |
68 | -- can be an empty list. |
69 | ---C++: return const & |
70 | returns ListOfShape from TopTools; |
71 | |
72 | NewEdges (me ; E : Edge from TopoDS) |
73 | ---Purpose: Returns the list of new edges built from an edge <E> |
74 | -- it can be an empty list. |
75 | ---C++: return const & |
76 | returns ListOfShape from TopTools; |
77 | |
78 | GetVerticesForSubstitute (me; VerVerMap: out DataMapOfShapeShape from TopTools); |
79 | ---Purpose: Returns the datamap of vertices with their substitutes. |
80 | |
81 | VerticesForSubstitute (me : in out; VerVerMap: in out DataMapOfShapeShape from TopTools); |
82 | ---Purpose: |
83 | |
84 | fields |
85 | |
86 | myFace : Face from TopoDS; |
87 | myConstEdges : ListOfShape from TopTools; |
88 | myVerOnEdges : DataMapOfShapeListOfShape from TopTools; |
