[ndnSIM] Searching fib face

[narjes aloulou]

Hi Alex and All,

My context:
When a node receives an interest, it will send it to a specific node after changing it.
So, how can i find the outgoing face towards this specific node.
(I suppose that there is only one route towards this node by this prefix ("/SpecificNode"))

I use this code in the method DoPropagateInterest in my forwarding strategy.

  Ptr<Node> node = this->GetObject<Node> ();
  Ptr<ndn::fib::Entry> fibEntryNode =node->GetObject<ndn::Fib> ()->Find (ndn::Name ("/SpecificNode"));

My question:
how i can find  the outgoing face ?
