I have a class Track and a class Jet and my event data consists
of a ROOT Tree in which there is a branch for tracks and a branch
for jets of a certain event.
Both Track and Jet contain a data member float fEnergy
In case I have the libs containing the Track and Jet classes
available in my ROOT environment there clearly is no problem,
since I can just use the Track and Jet member functions to investigate
e.g. the fEnergy of both of them and even plot one against the other.
However, in case I don't have the libs, I would use the MakeCode()
facility to be able to analyse the Tree.
As far as I can see this now gives a problem, since the fEnergy
would be related to both classes.
Question : Am I right here that the produced code can't work ?
Or does MakeCode properly take care of the problem ?
Obviously a way out would be to define fTrackEnergy and fJetEnergy,
but as far as I can see this is no solution once one thinks of
(re)using code of other related experiments.
Suggestion : In case MakeCode encounters the same variable name
in different branches, could then on each additional
occurence of that variable some suffix be added auto-
matically be MakeCode ?
In case of the above situation this would result in e.g. :
fEnergy and fEnergy_2
In case the problems I expect in the above are real, the latter
is just a suggestion and in case someone has a better solution
please let me know.
