<br>
There is no tracer for FIB content, since it is (it was) not intended to be dynamically modified. If you need to print out FIB contents (e.g., periodically, using Simulator::Schedule), there are a couple of ways. If you don't care about the format, you can do the following:<br>
<br>
input: Ptr<Node> node;<br>
std::cout << *node->GetObject<ndn::Fib> () << std::endl;<br>
<br>
If you need more precise control over what is printed out, it is also possible, but a little bit more complicated:<br>
<br>
Ptr<ndn::Fib> fib = node->GetObject<ndn::Fib> ();<br>
for (Ptr<ndn::fib::Entry> entry = fib->Begin (); entry != fib->End (); entry = fib->Next (entry))<br>
{<br>
std::cout << entry->GetPrefix () << std::endl;<br>
...<br>
}<br>
