Sorry, forgot to paste that...
fsie is from Flow_stats_in event, declared in a handle_flow_stats_in
method (a handler):
Disposition newcomp::handle_flow_stats_in(const Event& e){
*const Flow_stats_in_event& fsie*
= assert_cast<const Flow_stats_in_event&>(e);
So, fsie.flows has that informations about the flows, that can be used to
collect statistcs.
Thanks for help.
Regards.
