[ndnSIM] How to print FIB table?

[Muhammad Hosain Abdollahi Sabet]

Alex,

I have coded ndn-grid.py like this:

void
> printFIB(Ptr<Node> node)
> {
>     auto fib =
> node->GetObject<ndn::L3Protocol>()->getForwarder()->getFib();
>     cout<<std::endl<<fib.size()<<std::endl;
> }
>

and called it in scenario:

> Simulator::Schedule(Seconds(0.0), printFIB, nodes.Get(0));
>

Compiler says:

> error: use of deleted function ‘nfd::Fib::Fib(const nfd::Fib&)’
> note: ‘nfd::Fib::Fib(const nfd::Fib&)’ is implicitly deleted because the

Could you refer my to the correct example of correct C++ cunstructs?

Thanks,
Sabet
