\cgalConcept
A model of the concept `AlphaShapeTraits_2` must provide the following predicate and
operations in addition to the requirements for the underlying triangulation
traits class.
It means, the metric has to be Euclidean for Delaunay triangulation or the power
metric for regular triangulation.
The concept `AlphaShapeTraits_2` describes the requirements for the geometric traits
class of the underlying Delaunay triangulation of a basic alpha shape.

In addition to the requirements described in the concept
::DelaunayTriangulationTraits_2, the geometric traits class of a
Delaunay triangulation plugged in a basic alpha shapes provides the
following.
\cgalHasModel All models of `Kernel`.
