template<typename Coefficient >

Point_2 CGAL::Arr_algebraic_segment_traits_2< Coefficient >::Construct_point_2::operator()	(	Algebraic_real_1	x,
		Curve_2	cv,
		int	arcno
	)

Returns a Point_2 object that represents the arcno-th point in the fiber of cv at \( x\)-coordinate x, counted from the bottom, starting with zero.

Precondition

(cv must not have a vertical line at x, and \( 0\leq arcno < c\), where \( c\) is the number of points in the fiber of cv at x.)

operator()() [2/2]

template<typename Coefficient >

Point_2 CGAL::Arr_algebraic_segment_traits_2< Coefficient >::Construct_point_2::operator()	(	Algebraic_real_1	x,
		X_monotone_curve_2	xcv
	)

Returns a Point_2 object that represents the point on xcv at \( x\)-coordinate x

Precondition

(x is in the \( x\)-range of xcv.)
