> According to Ticket #4753 <https://svn.boost.org/trac/boost/ticket/4753> clear
> vertex should work on subgraph BUT according to documentation clear_vertex
> should remove all edges of specified vertex but in the boost 1.47
> implementation of clear_vertex of subgarph it removes only the out_edges()
> is there a prbolem with documentation or the issue was not fixed?

> The code of subgraph is:
>
> template <typename G>void
> clear_vertex(typename subgraph<G>::vertex_descriptor v, subgraph<G>& g) {
>   while (true) {
>     typedef typename subgraph<G>::out_edge_iterator oei_type;
>     std::pair<oei_type, oei_type> p = out_edges(v, g);
>     if (p.first == p.second) break;
>     remove_edge(*p.first, g);
>   }
> }

> Thanks
