Re: [Boost-users] [BGL] inv_adjacency_iterator is missing in graph_traits.hpp

Hi,

I have a bidirectional adjacency list and I want to use the inv_adjacent_vertices method However, the following code does not compile: typedef boost::graph_traits<Graph> Traits; typedef typename Traits::inv_adjacency_iterator inv_adjacency_iterator; inv_adjacency_iterator w, w_end; boost::tie (w, w_end) = inv_adjacent_vertices (v, g_);

The problem is that inv_adjacency_iterator is not part of boost::graph_traits :-(

Could you tell me how can I use the inv_adjacent_vertices method (i.e., how can I declare an inv_adjacent_iterator)?

Obviously, I found a workaround 2 minutes after sending this email... which consist in using the inv_adjacency_iterator_generator: typedef typename boost::inv_adjacency_iterator_generator::type inv_adjacency_iterator; Hope this will help someone else. Anyway, I would like to know why this type can't be also part of boost::graph_traits? -- Johan () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
