Definition

The concept HalfedgeListGraph refines the concept HalfedgeGraph and adds the requirements for traversal of all halfedges in the graph.

Refines:
HalfedgeGraph
Has Models:

template<typename HalfedgeListGraph >
std::pair< boost::graph_traits< HalfedgeListGraph >::halfedge_iterator, boost::graph_traits< HalfedgeListGraph >::halfedge_iterator > halfedges ( const HalfedgeListGraph &  g)
related

returns an iterator range over all halfedges.

template<typename HalfedgeListGraph >
boost::graph_traits< HalfedgeListGraph >::halfedge_size_type num_halfedges ( const HalfedgeListGraph &  g)
related

returns an upper bound of the number of halfedges of the graph.

Attention
num_halfedges() may return a number larger than std::distance(halfedges(g).first, halfedges(g).second). This is the case for implementations only marking halfedges deleted in the halfedge container.
