[ndnSIM] Create Custom Interest Packet, Send it & Examine It

[Arash Daneshmand]

Dear Spyridon,
Thank you for replying to my problem.
I've checked the example section in ndnSim website and all of them use the
class ndn::AppHelper to create a consumer and producer.
what I'm trying to do is build a custom interest ,convert it to a packet
and send it to the network. I've made the interest using these commands :

    shared_ptr<Interest> interest3 = make_shared<Interest>();
    interest3->setNonce(6);
    interest3->setName("interest3");
    time::milliseconds interestLifeTime(2);
    interest3->setInterestLifetime(interestLifeTime);

now I want to convert the interest to a packet. ndnSim used to have a class
(in versions 2.2 & before) called ns3::ndn::Convert that did the job using
these functions :

ns3::ndn::Convert::ToPacket< Data >(const T & pkt)
ns3::ndn::Convert::FromPacket< Data > (Ptr< Packet > packet)

what I need now is these exact functions to convert interest to packets.

Thank You In Advance for your Kind help.
