#include <CGAL/Dart.h>

Definition

The class Dart represents a dD dart.

\( \beta_i\) pointers are coded in a array of d+1 Dart_handle (because we describe also the \( \beta_0\) link). Attributes are associated to each dart by Attribute_handle<i>, one for each non void i-attribute.

Is Model Of:
Dart
Template Parameters
dan integer for the dimension of the dart.
CMapmust be a model of the CombinatorialMap concept.

Complexity

Each \( \beta_i\) link is initialized to CMap::null_dart_handle, and each attribute handle of non void i-attribute is initialized to NULL at the creation of the dart, thus the complexity of the creation is in O(d+1).

The complexity of opposite and other_extremity methods is in O(d+1).

Other methods have all a constant time complexity.
