#include <CGAL/HalfedgeDS_default.h>

Definition

template<typename Traits, typename HalfedgeDSItems = CGAL::Halfedge_DS_items_2, typename Alloc = CGAL_ALLOCATOR(int)>
class CGAL::HalfedgeDS_default< Traits, HalfedgeDSItems, Alloc >

The class HalfedgeDS_default is a model for the HalfedgeDS concept.

The second template parameter HalfedgeDSItems has a default argument CGAL::HalfedgeDS_items_2. The third template parameter Alloc uses the CGAL default allocator as default setting. HalfedgeDS_default is a list-based representation with bidirectional iterators that supports removal.

Is Model Of:
HalfedgeDS<Traits,Items,Alloc>

Implementation

Currently, HalfedgeDS_default is derived from CGAL::HalfedgeDS_list<Traits>. The copy constructor and the assignment operator need \( O(n)\) time with \( n\) the total number of vertices, halfedges, and faces.

Examples:
HalfedgeDS/hds_prog_color.cpp, HalfedgeDS/hds_prog_default.cpp, HalfedgeDS/hds_prog_edge_iterator.cpp, HalfedgeDS/hds_prog_graph.cpp, HalfedgeDS/hds_prog_graph2.cpp, and HalfedgeDS/hds_prog_halfedge_iterator.cpp.
