generic class FunctionTanCirCu from GccIter (
TheCurve as any;
TheCurveTool as any) -- as CurvePGTool from GccInt(TheCurve)
inherits FunctionWithDerivative from math
---Purpose: This abstract class describes a Function of 1 Variable
-- used to find a line tangent to a curve and a circle.
uses Circ2d from gp
is
Create (Circ : Circ2d from gp ;
Curv : TheCurve ) returns FunctionTanCirCu from GccIter;
Value (me : in out ;
X : Real ;
F : out Real ) returns Boolean;
---Purpose: Computes the value of the function F for the variable X.
-- It returns True if the computation is successfully done,
-- False otherwise.
Derivative (me : in out ;
X : Real ;
Deriv : out Real ) returns Boolean;
---Purpose: Computes the derivative of the function F for the variable X.
-- It returns True if the computation is successfully done,
-- False otherwise.
Values (me : in out ;
