#include <CGAL/HalfedgeDS_list.h>
The class HalfedgeDS_list
is a model for the HalfedgeDS
concept.
HalfedgeDS_list
is a list-based representation with bidirectional iterators that supports removal.

Implementation
HalfedgeDS_list
uses internally the CGAL::In_place_list
container class. The copy constructor and the assignment operator need \( O(n)\) time with \( n\) the total number of vertices, halfedges, and faces.
CGAL_ALLOCATOR(int)
is used as default argument for the Alloc
template parameter.
