class SurfCurvConstRadInv from BRepBlend
inherits SurfCurvFuncInv from Blend
---Purpose: Class used to compute a solution of the
-- surfRstConstRad problem on a done restriction of the
-- surface.
-- The vector <X> used in Value, Values and Derivatives
-- methods has to be the vector of the parametric
-- coordinates wguide, wcurv, wrst where wguide is the
-- parameter on the guide line, wcurv is the parameter on
-- the curve, wrst is the parameter on the restriction on
-- the surface.

NbEquations(me)
---Purpose: returns 3.
returns Integer from Standard;
Value(me: in out; X: Vector; F: out Vector)
---Purpose: computes the values <F> of the Functions for the
-- variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean from Standard;
Derivatives(me: in out; X: Vector; D: out Matrix)
---Purpose: returns the values <D> of the derivatives for the
-- variable <X>.

---Purpose: Returns in the vector InfBound the lowest values allowed
-- for each of the 3 variables.
-- Returns in the vector SupBound the greatest values allowed
-- for each of the 3 variables.
IsSolution(me: in out; Sol: Vector from math; Tol: Real from Standard)
---Purpose: Returns Standard_True if Sol is a zero of the function.
-- Tol is the tolerance used in 3d space.
returns Boolean from Standard;
