23 | generic class IntCurveCurveGen from IntCurve ( |
24 | TheCurve as any; |
25 | TheCurveTool as any) -- as CurveTool from IntCurve(TheCurve) |
26 | |
27 | ---Purpose: Provides the algorithm to intersect two 2D-curves. |
28 | -- The curves may be parametric curves or Conic (see |
29 | -- the template class CurveTool). |
30 | -- |
31 | -- Note: The exception ConstructionError is raised in |
32 | -- constructors or in Perform methods when a domain |
33 | -- (Domain from IntRes2d) is not correct, i-e when |
34 | -- the method TheType returns GeomAbs_Circle or |
35 | -- GeomAbs_Ellipsei and the corresponding domain is |
36 | -- not closed (use the SetEquivalentParameters for a |
37 | -- domain on a circle or an ellipse) or when the |
38 | -- method TheType returns GeomAbs_Other and the |
39 | -- domain of the curve is not bounded |
40 | -- (HasFirstPoint() && HasLastPoint() return True). |
