CGAL::Arr_extended_halfedge< HalfedgeBase, HData > Class Template Reference
DCEL

`#include <CGAL/Arr_extended_dcel.h>`

## Inherits from

HalfedgeBase.

## Definition

The `Arr_extended_halfedge` class-template extends the halfedge topological-features of the Dcel.

It is parameterized by a halfedge base-type `HalfedgeBase` and a data type `HData` used to extend the halfedge base-type.

Is Model Of:
  `ArrangementDcelHalfedge`

  `Arr_dcel_base<V,H,F>`

## Creation

void | assign (const Self &other)
| assigns `he` with the contents of the `other` vertex.

## Access Functions

const HData & | data () const
| obtains the auxiliary data (a non-const version, returning a reference to a mutable data object is also available).

## Modifiers

void | set_data (const HData &data)
| sets the auxiliary data.
