Definition

template<typename Traits, typename Vb, typename ExactAlphaComparisonTag>
class CGAL::Alpha_shape_vertex_base_2< Traits, Vb, ExactAlphaComparisonTag >

The class Alpha_shape_vertex_base_2 is the default model for the concept AlphaShapeVertex_2.

Template Parameters

Traits	has to be a model of `AlphaShapeTraits_2`.
Vb	has to be a model of `TriangulationVertexBase_2` (or `RegularTriangulationVertexBase_2`) if `Alpha_shape_vertex_base_2` is intended to be used with an alpha-shape class based on a `Delaunay_triangulation_2` (or a `Regular_triangulation_2`).
ExactAlphaComparisonTag	is a tag that, when set to `Tag_true`, triggers exact comparisons between alpha values. See the description provided in the documentation of `Alpha_shape_2` for more details. The default value is `Tag_false`.
