Detailed Description
TS NAIA Chain true TChain.
This class is derived from TChain and then has all the typical chain properties included the use of the of a TSelector class with the TChain::Process method. This class is intended to be used as alternative and in parallel with the NAIAChain class.
This class takes care of opening also the helper chains for the RTI and FILEinfo TTrees contained in a typical NAIA file. When using the GetEntry, GetEntryWithIndex, GetEvent and GetNextEvent this class takes care of automatically update the RTIInfo branch.
