## Object Creation Functors

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. More...

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 More...

Point_2 operator() (Algebraic_real_1 x, Algebraic_real_1 y)
Returns a Point_2 object that represents (x,y)

Point_2 operator() (Coefficient x, Coefficient y)
Returns a Point_2 object that represents (x,y)

Point_2 operator() (Bound x, Bound y)
Returns a Point_2 object that represents (x,y)

## ◆ operator()() [1/2]

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.)
