-- Methodes from Adaptor3d_Curve --
--------------------------------
FirstParameter(me) returns Real
is redefined static;
LastParameter(me) returns Real
is redefined static;
Continuity(me) returns Shape from GeomAbs
---Purpose:
is redefined static;
NbIntervals(me; S : Shape from GeomAbs) returns Integer
---Purpose: Returns the number of intervals for continuity
-- <S>. May be one if Continuity(me) >= <S>
is redefined static;
Intervals(me; T : in out Array1OfReal from TColStd;
S : Shape from GeomAbs)
---Purpose: Stores in <T> the parameters bounding the intervals
-- of continuity <S>.
--
-- The array must provide enough room to accomodate
-- for the parameters. i.e. T.Length() > NbIntervals()
raises
OutOfRange from Standard
is redefined static;
Trim(me; First, Last, Tol : Real) returns HCurve from Adaptor3d
---Purpose: Returns a curve equivalent of <me> between
-- parameters <First> and <Last>. <Tol> is used to
-- test for 3d points confusion.

DN (me; U : Real; N : Integer) returns Vec from gp
--- Purpose :
-- The returned vector gives the value of the derivative for the
-- order of derivation N.
raises

-- is not CN.
OutOfRange from Standard
--- Purpose : Raised if N < 1.
is redefined static;
