## CGAL::Arr_segment_traits_2<Kernel>

### Definition

The class Arr_segment_traits_2<Kernel> is a traits class for handling arrangements of line segments that uses the geometric kernel intensively. The Arr_segment_traits_2<Kernel>::Curve_2 type (as well as the Arr_segment_traits_2<Kernel>::X_monotone_curve_2 type) is actually the Kernel::Segment_2 type, while the various predicates and constructions supported by the traits class actually wrap the kernel implementations.

The Kernel must use a number type that supports exact computations with rational numbers, such as Quotient<Gmpz> or leda_rational. Other inexact representations can be used at the user's own risk.
