23 class CurveTool from Extrema
32 Array1OfReal from TColStd,
33 BezierCurve from Geom,
34 BSplineCurve from Geom,
35 CurveType from GeomAbs,
42 FirstParameter(myclass; C : Curve from Adaptor3d)
43 returns Real from Standard;
46 LastParameter(myclass; C : Curve from Adaptor3d)
47 returns Real from Standard;
50 Continuity(myclass; C: Curve from Adaptor3d) returns Shape from GeomAbs;
53 NbIntervals(myclass; C: in out Curve from Adaptor3d; S : Shape from GeomAbs) returns Integer;
54 ---Purpose: Returns the number of intervals for continuity
55 -- <S>. May be one if Continuity(me) >= <S>
59 Intervals(myclass; C: in out Curve from Adaptor3d; T : in out Array1OfReal from TColStd;
60 S : Shape from GeomAbs);
61 ---Purpose: Stores in <T> the parameters bounding the intervals
64 -- The array must provide enough room to accomodate
65 -- for the parameters. i.e. T.Length() > NbIntervals()
