[ndnSIM] Getting Hop Count on Insert Method for New Custom Policy

[Rizky Yanuar]

Hello,

I'm trying to get the hop count from a packet in a new custom policy based
from existing policy (which is freshness-policy). I've tried using the
example that's Alex mentioned in this mail:
http://www.lists.cs.ucla.edu/pipermail/ndnsim/2016-February/002423.html

However, on the compiling process I still got an error message:

In file included from
../src/ndnSIM/model/cs/content-store-with-freshness.hpp:28:0,
                 from
../src/ndnSIM/model/cs/content-store-with-freshness.cpp:20:
../src/ndnSIM/model/cs/custom-policies/freshness-policy.hpp: In member
function ‘bool ns3::ndn::ndnSIM::freshness_policy_traits::policy<Base,
Container, Hook>::type::insert(typename
ns3::ndn::ndnSIM::freshness_policy_traits::policy<Base, Container,
Hook>::type::parent_trie::iterator)’:
../src/ndnSIM/model/cs/custom-policies/freshness-policy.hpp:114:27: error:
expected unqualified-id before ‘typename’
      auto dataTag = data->typename getTag<Ns3PacketTag>();
                           ^

I've tried remove the typename declaration and the <Ns3PacketTag> but I
still failed on the compilation process. I'd greatly appreciate if anyone
has any advice for this problem. Thank you very much.
