22 | class Loop from BOP inherits TShared from MMgt |
23 | |
24 | ---Purpose: |
25 | -- A Loop is an existing shape (Shell,Wire) or a set |
26 | -- of shapes (Faces,Edges) which are connex. |
27 | -- a set of connex shape is represented by a BlockIterator |
28 | |
29 | uses |

31 | Shape from TopoDS, |
32 | BlockIterator from BOP, |
33 | ShapeEnum from TopAbs |

35 | is |
36 | |
37 | Create(S : Shape from TopoDS) |
38 | returns mutable Loop; |
39 | ---Purpose: |
40 | --- Creates the object using the shape S; |
41 | --- |
42 | Create(BI : BlockIterator from BOP) |
43 | returns mutable Loop; |
44 | ---Purpose: |
45 | --- Creates the object using the BlockIterator BI; |
46 | --- |
47 | IsShape(me) |
48 | returns Boolean from Standard |
49 | is virtual; |
50 | ---Purpose: |
51 | --- Returns TRUE if the object was created using shape |
52 | --- |
53 | Shape(me) |
54 | returns Shape from TopoDS |
55 | is virtual; |
56 | ---C++: return const & |
57 | ---Purpose: |
58 | --- Returns Shape from which the object was created |
59 | --- Valid only when IsShape() is TRUE |
60 | --- |
61 | BlockIterator(me) |
62 | returns BlockIterator |
63 | is static; |
64 | ---C++: return const & |
65 | --- Returns BlockIterator from which the object was created |
66 | --- Valid only when IsShape() is FALSE |
