generic class ImpParTool from IntImpParGen (
ImpTool as any; -- as ImpTool from IntImpParGen
ParCurve as any;
ParTool as any) -- as ParTool from IntImpParGen(ParCurve)
inherits FunctionWithDerivative from math
---Purpose: Implements the function used by FunctionAllRoots
-- to find the areas where the distance between the
-- implicit and the parametric curves is less than a
-- tolerance.
uses Pnt2d from gp,
Vec2d from gp
is
Create(IT: ImpTool; PC: ParCurve)
---Purpose: Constructor of the class.
returns ImpParTool from IntImpParGen;
Value(me: in out; Param: Real from Standard; F: out Real from Standard)
---Purpose: Computes the value of the signed distance between
-- the implicit curve and the point at parameter Param
-- on the parametrised curve.
returns Boolean from Standard

Derivative(me: in out; Param: Real from Standard;
D: out Real from Standard)
---Purpose: Computes the derivative of the previous function at
-- parameter Param.
