ArrangementLandmarkTraits_2 Concept Reference
Traits Concepts

## Definition

The concept `ArrangementLandmarkTraits_2` refines the traits concepts `ArrangementApproximateTraits_2` and `ArrangementConstructXMonotoneCurveTraits_2`. The type of an arrangement associated with the landmark point-location strategy (see `CGAL::Arr_landmarks_point_location`) must be an instance of the `CGAL::Arrangement_2<Traits,Dcel>` class template, where the Traits parameter is substituted with a model of this concept.

Refines:
  `ArrangementApproximateTraits_2` and `ArrangementConstructXMonotoneCurveTraits_2`

Has Models:

  `CGAL::Arr_conic_traits_2<RatKernel,AlgKernel,NtTraits>`

  `CGAL::Arr_non_caching_segment_traits_2<Kernel>`

  `CGAL::Arr_segment_traits_2<Kernel>`

  `CGAL::Arr_polycurve_traits_2<GeometryTraits_2>`

  `CGAL::Arr_polyline_traits_2<SegmentTraits_2>`

  `CGAL::Arr_rational_function_traits_2`

Has Models:
  `CGAL::Arr_linear_traits_2<Kernel>`
