FixedAlphaShapeVertex_3 Concept Reference
Concepts

## Definition

This concept describes the requirements for the base vertex of a alpha shape with a fixed value alpha.

Refines:
  `TriangulationVertexBase_3`

Has Models:
  `CGAL::Fixed_alpha_shape_vertex_base_3`

## Types
typedef unspecified_type | Point
| Must be the same as the point type provided by the geometric traits class of the triangulation.

## Creation
| FixedAlphaShapeVertex_3 ()
| default constructor.
| FixedAlphaShapeVertex_3 (Point p)
| constructor setting the point.
| FixedAlphaShapeVertex_3 (Point p, const Cell_handle &c)
| constructor setting the point and an incident cell.

## Access Functions
bool | is_on_chull ()
| Returns a boolean indicating whether the point is on the convex hull of the point of the triangulation.
Classification_type | get_classification_type ()
| Returns the classification of the vertex.

## Modifiers
void | set_classification_type (Classification_type type)
| Sets the classification of the vertex.
void | is_on_chull (bool b)
| Sets whether the vertex is on the convex hull.
