Why isn't there any "dequeS" tag in BGL?
Historical accident. If you'd like we could add your implementation for deque.
Below you find my implementation for deque. Regards Nicola PS: sorry for forgetting the subject in my previous post, causing a mess with message threading... #include <boost/graph/graph_traits.hpp> #include <boost/graph/adjacency_list.hpp> #include <deque> namespace boost { namespace graph_detail { struct deque_tag : virtual public random_access_container_tag, virtual public back_insertion_sequence_tag { }; // No front_insertion_sequence_tag? template <class T, class Alloc> deque_tag container_category(const std::deque<T, Alloc>&){ return deque_tag(); } template <class T, class Alloc> unstable_tag iterator_stability(const std::deque<T, Alloc>&) { return unstable_tag(); } #if !defined BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION template <class T, class Alloc> struct container_traits< std::deque<T, Alloc> > { typedef deque_tag category; typedef unstable_tag iterator_stability; }; #endif } // namespace graph_detail struct dequeS { }; template <typename ValueType> struct container_gen<dequeS, ValueType> { typedef typename std::deque<ValueType> type; }; } // namespace boost // Test int main(int, char*[]) { typedef boost::adjacency_list<boost::vecS, boost::dequeS, boost::bidirectionalS> Graph; Graph g; Graph::vertex_descriptor v1, v2; v1 = boost::add_vertex(g); v2 = boost::add_vertex(g); boost::add_edge(v1, v2, g); }
