22 | class WireEdgeClassifier from TopOpeBRepBuild |
23 | inherits CompositeClassifier from TopOpeBRepBuild |
24 | |
25 | ---Purpose: |
26 | -- Classify edges and wires. |
27 | -- shapes are Wires, Element are Edge. |
28 | |
29 | uses |
30 | |
31 | ShapeEnum from TopAbs, |
32 | State from TopAbs, |
33 | Shape from TopoDS, |
34 | Pnt2d from gp, |

42 | Create(F : Shape from TopoDS; |
43 | BB : BlockBuilder) returns WireEdgeClassifier; |
44 | ---Purpose: Creates a classifier on edge <F>. |
45 | -- Used to compare edges and wires on the edge <F>. |
46 | |
47 | Compare(me : in out; L1,L2 : Loop) returns State from TopAbs |

51 | returns Shape from TopoDS; |
52 | |
53 | CompareShapes(me : in out; B1,B2 : Shape from TopoDS) |
54 | ---Purpose: classify wire <B1> with wire <B2> |
55 | returns State from TopAbs; |
56 | |
57 | CompareElementToShape(me : in out; E,B : Shape from TopoDS) |
58 | ---Purpose: classify edge <E> with wire <B> |
59 | returns State from TopAbs; |
60 | |
61 | ResetShape(me : in out; B : Shape from TopoDS); |
62 | ---Purpose: prepare classification involving wire <B> |
63 | -- calls ResetElement on first edge of <B> |
64 | |
65 | ResetElement(me : in out; E : Shape from TopoDS); |
66 | ---Purpose: prepare classification involving edge <E> |
67 | -- define 2D point (later used in Compare()) on first vertex of edge <E>. |
68 | |
73a97e76 |
69 | CompareElement(me : in out; E : Shape from TopoDS) |
70 | returns Boolean from Standard; |
7fd59977 |
71 | ---Purpose: Add the edge <E> in the set of edges used in 2D point |
72 | -- classification. |
73 | |
74 | State(me : in out) returns State from TopAbs; |
75 | ---Purpose: Returns state of classification of 2D point, defined by |
76 | -- ResetElement, with the current set of edges, defined by Compare. |
