## Definition

template<typename Traits>
class CGAL::Arr_default_dcel< Traits >

The default DCEL class used by the `Arrangement_2` class-template is parameterized by a traits class, which is a model of the `ArrangementBasicTraits_2` concept.

It simply uses the nested `Traits::Point_2` and `Traits::X_monotone_curve_2` to instantiate the base vertex and halfedge types, respectively. Thus, the default DCEL records store no other information, except for the topological incidence relations and the geometric data attached to vertices and edges.

Is Model Of:
  `ArrangementDcelWithRebind`
