CGAL 4.13  2D Arrangements

#include <CGAL/Arr_non_caching_segment_basic_traits_2.h>
Inherited by CGAL::Arr_non_caching_segment_traits_2< Kernel >.
The traits class Arr_non_caching_segment_basic_traits_2
is a model of the ArrangementTraits_2
concept that allow the construction and maintenance of arrangements of sets of pairwise interiordisjoint line segments.
It is templated with a CGALKernel model, and it is derived from it. This traits class is a thin layer above the parameterized kernel. It inherits the Point_2
from the kernel and its X_monotone_curve_2
type is defined as Kernel::Segment_2
. Most traitsclass functor are inherited from the kernel functor, and the traits class only supplies the necessary functors that are not provided by the kernel. The kernel is parameterized with a number type, which should support the arithmetic operations \( +\), \( \) and \( \times\) in an exact manner in order to avoid robustness problems. Using Cartesian<MP_Float>
or Cartesian<Gmpz>
are possible instantiations for the kernel. Using other (inexact) number types (for example, instantiating the template with Simple_cartesian<double>
) is also possible, at the user's own risk.
