## Definition

template<typename K, typename MTag>
struct CGAL::Segment_Delaunay_graph_traits_without_intersections_2< K, MTag >

The class `Segment_Delaunay_graph_traits_without_intersections_2` provides a model for the `SegmentDelaunayGraphTraits_2` concept.

Template Parameters

  K | must be a model of the `Kernel` concept.
  MTag | corresponds to how predicates are evaluated. There are two possible values for `MTag`, namely `Field_with_sqrt_tag` and `Euclidean_ring_tag`. The first one must be used when the number type used in the representation supports the exact evaluation of signs of expressions involving all four basic operations and square roots, whereas the second one requires the exact evaluation of signs of ring-type expressions, i.e., expressions involving only additions, subtractions and multiplications. The default value for `MTag` is `Euclidean_ring_tag`. The way the predicates are evaluated is discussed in [2] and [4] (the geometric filtering part).
