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;
