deferred class Function2d from AppCont
---Purpose: deferred class describing a continous 2d function f(u)
uses Pnt2d from gp,
Vec2d from gp
is
Delete(me:out) is virtual;
---C++: alias "Standard_EXPORT virtual ~AppCont_Function2d(){Delete() ; }"
FirstParameter(me) returns Real
---Purpose: returns the first parameter of the function.
is deferred;
LastParameter(me) returns Real
---Purpose: returns the last parameter of the function.
is deferred;
Value(me; U: Real) returns Pnt2d
---Purpose: returns the point at parameter <U>.
is deferred;
D1(me; U: Real; P: in out Pnt2d; V: in out Vec2d) returns Boolean
---Purpose: returns the point and the derivative values at
-- the parameter <U>.
is deferred;
end Function2d;
