Dear ROOT experts,
For filling a THn, I can use the following function:
Fill (const Double_t *x, Double_t w=1.)
This performs an expensive lookup of the bin number.
If I'm filling many THn with the same dimensions, I would like to avoid many lookups, and ask for the bin number once. Then with the knowledge of the bin number, I would like to use
void FillBin (Long64_t bin, Double_t w)
but this is a protected member function.
As I see it now I have to use a set of other public functions in order to update all information of the THn:
AddBinContent (Long64_t bin, Double_t v=1.)
AddBinError2 (Long64_t bin, Double_t e2)
plus a combination of SetEntries (Double_t entries) and Double_t GetEntries () const
Do I see this correctly? Wouldn't it be helpful in this case if void FillBin (Long64_t bin, Double_t w) was a public function?
