Very good question. I do iterate but if there is something better... template <typename Graph> void remove_vtx_from_id(const int id, Graph& g) { typename boost::graph_traits<Graph>::vertex_iterator vi, vi_end; boost::tie(vi, vi_end) = boost::vertices(g); for (; vi != vi_end; ++vi) { if (get(boost::vertex_index_t(), g, *vi) == id) { clear_vertex(*vi, g); remove_vertex(*vi, g); break; } } } Am 09.07.2008 um 12:56 schrieb M.

Hello list members,

I've a little question:

Is it possible and if so, how is it possible, to randomly access a vertex or edge by its id (according to vertex_index or edge_index proprty map)?, i.e. calling 'vertices(graph)[id]'.

My problem is that I wan't to access a vertex or edge in an unique and graph lifespan-wide manner without iterate over all vertices or edges. With vertex_descriptor/edge_discriptor it's possible but only if I don't change the graph structur (not lifespan-wide).
