Hi,
I have met a stupid problem ...
I use TSelector to analyze a disk resident TNtuple.
The TNtuple has a "simple" branch :
Float_t x;
TBranch *b_x;
In my "TSelector::ProcessFill(Int_t entry)" I need, however, to access not
only the "entry", but also "entry - 100000" and "entry + 100000" for that
specific branch :
b_x->GetEntry(entry); x1 = x;
b_x->GetEntry(entry - 100000); x0 = x;
b_x->GetEntry(entry + 100000); x2 = x;
The result is that the analysis ("Process") of the ntuple takes ages ...
Can I somehow speed it up ?
Thanks in advance,
Jacek.
