## Definition

Requirements of the halfedge type required for the polyhedron built by the function `CGAL::convex_hull_3()`.

Has Models:
  CGAL::Polyhedron_3::Halfedge

## Creation

| Halfedge ()
| default constructor.

## Operations

Halfedge_handle | opposite ()
| the opposite halfedge.
Halfedge_handle | next ()
| the next halfedge around the facet.
Halfedge_handle | prev ()
| the previous halfedge around the facet.
bool | is_border () const
| is true if `h` is a border halfedge.
Halfedge_around_facet_circulator | facet_begin ()
| circulator of halfedges around the facet (counterclockwise).
Vertex_handle | vertex ()
| the incident vertex of `h`.
Facet_handle | facet ()
| the incident facet of `h`. More...

## Member Function Documentation

Facet_handle ConvexHullPolyhedronHalfedge_3::facet | ( | ) |  |

the incident facet of `h`.

If `h` is a border halfedge the result is default construction of the handle.
