Problem connecting to TraceSource

[Vikash Kathirvel]

I am struggling to figure out the correct path when using Config::Connect to connect to the child class.

For example, if i want to connect to an Rlc Trace Source of a UE I do:

Config::Connect (basePath + "/DataRadioBearerMap/*/LteRlc/TxPDU")

However, now i have added a Trace Source specifically for the AM mode and want to connect to it.

I tried,

Config::Connect (basePath + "/DataRadioBearerMap/*/LteRlcAm/MyCustomTrace")    //This does not work

Can anyone explain what i am doing wrong, and how i am supposed to connect to this new trace source of the child class since LteRlcAm inherits LteRlc?

Anh Help would be greatly apprciated.

Thanks.

After going through : Determine path of attribute or Trace Source

I tried to match :

Config::MatchContainer amobjects = Config::LookupMatches(basePath + "/DataRadioBearerMap/*/$ns3::LteRlcAm/"); //Returns empty

The above code snippet returns an empty vector.

However if i do:

Config::MatchContainer objects = Config::LookupMatches(basePath + "/DataRadioBearerMap/*/LteRlc/");

This does return an object. But i am sure that the object is ns3::LteRlcAm because i matched the TIDs

Why doesn't the first code snippet return empty? 

Any help would be appreciated.

Thanks.

Hi,

the DataRadioBearerMap holds the base class pointers. That's why you call them by the base class name.
