[nox-dev] Building custom events

); register_handlerObservation_event (boost::bind(MioComp::handle_observation_event, this, _1)); } I tried also to add the event in the nox/src/etc/nox.json, including also the name of MyComp in the priority list, but the outcome is the same.

[nox-dev] A question about network.graph.hh

Hi guys, I'm using the hop struct defined in the file network-graph.hh. I was able to navigate the structure, and I've well understood its recursive nature. But I have a question: for what stands the uint64_t field in the std::liststd::pairuint16_t, hop* next_hops ? Thank you -- Andrea
