[Boost-users] [BGL] Serializing a filtered_graph

Hi, I was wondering if there is a way to serialize filtered_graphs? My first attempts fail because keep_all seems not to be serializable: /usr/include/boost/serialization/access.hpp:109: error: ‘struct boost::keep_all’ has no member named ‘serialize’ I have no problems serializing even custom adjacency_lists using the same approach. Besides discussing if it actually makes sense to serialize a filtered_graph, I am interested in suggestions on how to achieve it (if it is indeed possible). Thank you. Best regards, Cedric
