[ndnSIM] Getting the origin of an Interest

[Eric Binnendyk]

Hi,

In the forwarding strategy code, I am trying to find the node that an
incoming Interest originated from. I suspect that this information is
somewhere in the PIT entry (possibly in pitEntry->getInRecords()), however
I cannot figure out how to find it.

Does anyone know how to find the origin node of an Interest? I expect the
code will look something like this:

if (pitEntry->getInRecord()->...->origin == nodes.Get(i)) {
num_interests_per_origin[i] += 1;
}
}

Thanks,

Eric
