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