[ndnSIM] Question on accessing each node at a script file.

[황인찬]

Dear NDN researchers,

I have been trying to access a node and get its information in a script
file.
In my script,
Ptr<Node> node0 = nodes.Get(0); .// to access node,

std::cout << "Missed Int for node 0  : " <<
node0->GetObject<ns3::ndn::L3Protocol>()->getForwarder()->getNameTree()->size()
<< std::endl;
// To get information.

Strangely, it only works until
 "node0->GetObject<ns3::ndn::L3Protocol>()->getForwarder()" but not further
than it.
I cannot access getPit or whatsoever.

I was using this approach because of the code in the visualizer.

https://github.com/NDNUtils/NDNSIM/blob/master/src/visualizer/visualizer/core.py#L401-L414

Can anyone of you tell me how to assess the information? such as getPit(),
getNameTree() and so on?

Best wishes,

inchan hwang
