[ndnSIM] A question about printing out PIT contents

[Alex Afanasyev]

Hi Amin,

Since this information belongs to each individual face (FaceMetric instance) inside FIB entry, you need to access individual items like this:

Ptr<ndn::Pit> pit = node->GetObject<ndn::Pit> ();
for (Ptr<ndn::pit::Entry> entry = pit->Begin (); entry != pit->End (); entry = pit->Next (entry))
  {
    std::cout << "=========" << std::endl;
    std::cout << entry->GetPrefix () << std::endl;

    for (FaceMetricContainer::type::index<i_nth>::type::iterator metric =
           entry->m_faces.get<i_nth> ().begin ();
         metric != entry->m_faces.get<i_nth> ().end ();
         metric++)
      {
        os << metric->GetSRtt () << ", " << metric->GetRttVar << "\t";
      }
  }
