Member Function Documentation

def ntupleDataFormat.TrackMatchInfo.__getattr__ (   self,
  attr 
) 
Custom __getattr__ because of the second index needed to access the branch.

Note that when mapping the 'attr' to a branch, a 'trk' is
prepended and the first letter of 'attr' is turned to upper
case.
