#include <CGAL/Arr_rational_function_traits_2.h>
The Curve_2
class nested within the traits is used to represent rational functions which may be restricted to a certain x-range.

typedef AlgebraicKernel_d_1::Polynomial_1 | Polynomial_1 |
typedef AlgebraicKernel_d_1::Algebraic_real_1 | Algebraic_real_1 |
Operations | |
const Polynomial_1 & | numerator () const |
returns the numerator of the supporting rational function. | |
const Polynomial_1 & | denominator () const |
returns the denominator of the supporting rational function. | |
bool | is_continuous () const |
returns whether çurve is continuous, namely whether it does not contains any vertical asymptotes in its interior. | |
Arr_parameter_space | left_parameter_space_in_x () const |
returns whether the \( x\)-coordinate of çurve's left end is finite or whether it is \( \pm\infty\). | |
Arr_parameter_space | right_parameter_space_in_x () const |
returns whether the \( x\)-coordinate of çurve's right end is finite or whether it is \( \pm\infty\). | |
Algebraic_real_1 | left_x () const |
returns the \( x\)-coordinate of the left end. More... | |
Algebraic_real_1 | right_x () const |
returns the \( x\)-coordinate of the right end. More... | |
Algebraic_real_1 CGAL::Arr_rational_function_traits_2< AlgebraicKernel_d_1 >::Curve_2::left_x | ( | ) | const |

Algebraic_real_1 CGAL::Arr_rational_function_traits_2< AlgebraicKernel_d_1 >::Curve_2::right_x | ( | ) | const |
returns the \( x\)-coordinate of the right end.
