[ndnSIM] What is the correct namespace

[任沛]

Hi John,


Thank you for you reply, your suggestion really works! While after i compile the code, i got the error:


no matching function for call to ‘ns3::ndn::GlobalRoutingHelper::AddOrigins(std::string&, ns3::Ptr<ns3::Node>&)’
         ndnGlobalRoutingHelper.AddOrigins(prefix, testNode);
                                                                                  ^



I don't know why the error will happen, cause the code


ns3::Ptr<ns3::Node> testNode = ns3::Names::Find<ns3::Node>(tNode);


now works well, the form of "testNode" is apparently ns3::Ptr<ns3::Node>?


Thank you!

Perhaps you are missing #include directives?  For example, names.h is where Names lives.

Names is a class declared in ns3, and inside ns3 namespace.


So ns3::Names::Find might work?


And GlobalRoutingHelper is in ndn-global-routing-helper.h


Does this help?

Hi ndnSIM friends,


In NFD/daemon/fw/forwarder.cpp, i add below codes to the onIncomingData():


ns3::Ptr<ns3::Node> testNode = Names::Find<ns3::Node>(tNode);
ns3::ndn::GlobalRoutingHelper ndnGlobalRoutingHelper;
ndnGlobalRoutingHelper.AddOrigins(prefix, testNode);
ns3::ndn::GlobalRoutingHelper::CalculateRoutes();


where "tNode" and "prefix" above is in the form of std::string. What i tried to do is to tell all the another nodes that the current node can provide the content with specific prefix. While when i compile the source code, i got below message:


'Names' has not been declared
expected primary-expression before '>' token
'GlobalRoutingHelper' is not a member of 'ns3::ndn'
expected ';' before 'ndnGlobalRoutingHelper'
'ndnGlobalRoutingHelper' was not declareded in this scope
'ns3::ndn::GlobalRoutingHelper' has not been declared


What is the correct namespace? 


Look forward to your reply.
