ROOT 6.14/05 Reference Guide |
This class is an interface to the Hbook objects in Hbook files.
Any Hbook object (1-D, 2-D, Profile, RWN or CWN can be read
NB: a THbookFile can only be used in READ mode Use the utility in $ROOTSYS/bin/h2root to convert Hbook to Root
Example of use:
gSystem->Load("libHbook"); THbookFile f("myfile.hbook"); f.ls(); TH1F *h1 = (TH1F*)f.Get(1); //import histogram ID=1 in h1 h1->Fit("gaus"); THbookTree *T = (THbookTree*)f.Get(111); //import ntuple header T->Print(); //show the Hbook ntuple variables T->Draw("x","y<0"); // as in normal TTree::Draw
THbookFile can be browsed via TBrowser.
