Hi rooters,
Why the applied script do not work in case of chains?
Event - is the Event calss from root/test
If comment out lines correspondent to chain and uncomment TTree,
everything works fine.
I use root 3.03/05 (with previous version it was the same)
Regards,
Valeri
//---test.C------------------------------------------------------------
TFile *f = 0;
//TTree *chain =0;
TChain *chain =0;
void test()
{
gSystem->Load("libEvent.so");
chain = new TChain("T");
chain->Add("Event.root");
//f = new TFile("Event.root");
//chain = (TTree*)f->Get("T");
Event *event = new Event(); // in case of chain new required! Why?
chain->SetBranchStatus("*",1);
chain->SetBranchStatus("fTracks*",0);
chain->SetBranchAddress("event",&event);
int entries = chain->GetEntries();
printf("chain has %d entries\n",entries);
for(int i=0; i<entries; i++ ) {
chain->GetEntry(i);
printf("entry %d with %d tracks\n",i,event->GetNtrack());
}
}
