The problem is that my nodes have to gather data coming from some path of interest along the graph (depending on the type of the node), otherwise they just have to forward the received message adding their id to the message path (more or less). It's like a postal tracking system.
The problem is that I have to reset the "outbox" of each vertex once the messages have been sent.. Do you think that it makes sense in this case to have an outbox of messages (destination, message) in each vertex and reset it in the postSuperstep() of the VertexUpdateFunction?
