I'm new to ndnSIM also, and Spyridon or one of the other more experienced
members can correct me if I'm wrong, but in a sample I was working on, this
is how I got information from the *content store*, and I suspect it's
*similar* to the *PIT*:

Given a Content Store initialized thusly:
* //get the content store for the node     *
*     nfd::Cs& myContentStore = l3->getForwarder()->getCs();*

I iterate through the items:

* //use iterators to move through the content store*
*     for(auto it = myContentStore.begin();*
*         it != myContentStore.end();*
*         ++it)*
*     { *
*        cout<<it->getName()<<endl; //it represents a shared_ptr*
*                           //to a single Data item*
*     } *

Hope this is useful to you and others.
