## Inherits from

Fb.

## Definition

The class `Alpha_shape_face_base_2` is the default model for the concept `AlphaShapeFace_2`.

Template Parameters

  Traits | has to be a model of `AlphaShapeTraits_2`.
  Fb | has to be a model of `TriangulationFaceBase_2` (or `RegularTriangulationFaceBase_2`) if `Alpha_shape_face_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`.

Is Model Of:
  `AlphaShapeFace_2`

Examples:
  Alpha_shapes_2/ex_alpha_shapes_2.cpp, and Alpha_shapes_2/ex_weighted_alpha_shapes_2.cpp.
