According to 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 p = out_edges(v, g);     if (p.first == p.second) break;     remove_edge(*p.first, g);   } }

The clear_vertex function for subgraphs is undocumented; it is only "officially" in adjacency_list and adjacency_matrix. It should be fixed, however. I generally recommend not using subgraph anyway; filtered_graph is simpler for most use cases. -- Jeremiah Willcock
