Hi Adam, I don't know if you are actually particulary interested into the steps that will _not_ involve copying, or if you are simply interested into getting the graph resulting from the filtering into the original graph-type. In case you don't care about the copying, you can simply use copy_graph() (defined in boost/graph/copy.hpp). Although I could imagine that avoiding copying might be quite crucial for your applications. |
