22 private class InterFunc from Adaptor3d inherits FunctionWithDerivative from math
24 ---Purpose: Used to find the points U(t) = U0 or V(t) = V0 in
25 -- order to determine the Cn discontinuities of an
26 -- Adpator_CurveOnSurface relativly to the
27 -- discontinuities of the surface.

32 raises ConstructionError
35 Create (C : HCurve2d from Adaptor2d; FixVal: Real from Standard;
38 raises ConstructionError from Standard;
39 ---Purpose: build the function U(t)=FixVal if Fix =1 or
40 -- V(t)=FixVal if Fix=2
42 Value(me: in out; X: Real; F: out Real)
43 ---Purpose: computes the value <F>of the function for the variable <X>.
44 -- Returns True if the calculation were successfully done,
50 Derivative(me: in out; X: Real; D: out Real)
51 ---Purpose: computes the derivative <D> of the function
52 -- for the variable <X>.
53 -- Returns True if the calculation were successfully done,
59 Values(me: in out; X: Real; F, D: out Real)
60 ---Purpose: computes the value <F> and the derivative <D> of the
61 -- function for the variable <X>.
62 -- Returns True if the calculation were successfully done,
