Dears,
In the TTree class we have the member class TTree::SetBranchStatus(…) to disable some branch we want in a Tree in analysis to speed up the process. I would like to know if the class TTreeReader is constructed to already take this property into account or we also should speed up the reading of a Tree using some TTreeReader class member (or is not possible to do such kind of thing). I look at the documentation of TTreeReader class but, there is no reference to a method that can do that or if it is already implemented inside TTreeReader. Does somebody know something about?
