This is the normal behavior for ROOT File produced by HepTuple. As long as
you created the HepTuple properly this should work fine. Please let me know
if there is any other problems. Note that problem related to the use of
HepTuple are more appropriatedly send to about-root@fnal.gov
Cheers,
Philippe

Subject: [ROOT] MakeClass bug?
Hi,
I am trying to run MakeClass off of a TTree. It gives me the following
snippets:
class NNAna {
public :
TTree *fChain; //!pointer to the analyzed TTree or TChain
Int_t fCurrent; //!current Tree number in a TChain
//Declaration of leaves types
Int_t Jet_B_njet;
Float_t Jet_B_chf[64]; //[njet]
Float_t Jet_B_e[64]; //[njet]
Float_t Jet_B_emf[64]; //[njet]
Float_t Jet_B_et[64]; //[njet]
Float_t Jet_B_eta[64]; //[njet]
Float_t Jet_B_etad[64]; //[njet]
Float_t Jet_B_grde[64]; //[njet]
Float_t Jet_B_jetprobrphi[64]; //[njet]
Int_t Jet_B_nch[64]; //[njet]
Int_t Jet_B_ngoodrphitracks[64]; //[njet]
Int_t Jet_B_ntracks[64]; //[njet]
Float_t Jet_B_phi[64]; //[njet]
Float_t Jet_B_px[64]; //[njet]
Float_t Jet_B_py[64]; //[njet]
Float_t Jet_B_pz[64]; //[njet]
Int_t Jet_B_trackIndices[64][200]; //[njet]
.
.
.
};
.
.
.
void NNAna::Init(TTree *tree)
{
// Set branch addresses
if (tree == 0) return;
fChain = tree;
fCurrent = -1;
fChain->SetMakeClass(1);
fChain->SetBranchAddress("Jet_B",&Jet_B_njet);
//------
// Shouldn't there be some stuff here to init the leaves
// to the variables in the class?????
/-------
Notify();
}
The MakeClass function sets the pointers to the branches, but not to the
leaves. Is this a bug, or am I using this wrong?
Thank you!
Sal Rappoccio
