Adjacency Iterator AdaptorDefined in header boost/graph/adjacency_iterator.hppThe adjacency iterator adaptor transforms an out_edge_iterator into an adjacency iterator. That is, it takes an iterator that traverses over edges, and creates an iterator that traverses over the target vertices of those edges. With this adaptor it is trivial to take a graph type that models Incidence Graph and add the capabilities required of Adjacency Graph. Synopsisnamespace boost { template <class Graph, class VertexDescriptor, class OutEdgeIter> class adjacency_iterator_generator { public: typedef iterator_adaptor<...> type; }; } ExampleThe following is an example of how to use the adjacency_iterator_generator class.
#include <boost/graph/adjacency_iterator.hpp> class my_graph { // ... typedef ... out_edge_iterator; typedef ... vertex_descriptor; typedef boost::adjacency_iterator_generator<my_graph, vertex_descriptor, out_edge_iterator>::type adjacency_iterator; // ... }; Template Parameters
Model ofThe adjacency iterator adaptor (the type adjacency_iterator_generator<...>::type) is a model of Multi-Pass Input Iterator .MembersThe adjacency iterator type implements the member functions and operators required of the Random Access Iterator concept, except that the reference type is the same as the value_type so operator*() returns by-value. In addition it has the following constructor:adjacency_iterator_generator::type(const OutEdgeIter& it, const Graph* g) Revised 19 Aug 2001 ? Copyright Jeremy Siek 2000.
