[Boost-users] [Graph] dijkstra_shortest_paths color map

I work with very large implicit graphs that use out-of-core storage for properties, including the vertex color property, but the following bit of code in dijkstra_shortest_paths_no_init (boost-1.33.0) seems to preclude the use of a custom color map. std::vector<default_color_type> color(num_vertices(g)); default_color_type c = white_color; breadth_first_visit(g, s, Q, bfs_vis, make_iterator_property_map(&color[0], index_map, c)); What is the rationale for the above code, and how should I work around it?
