THbookTree Class Reference

A wrapper class supporting Hbook ntuples (CWN and RWN).

The normal TTree calls can be used, including TTree::Draw(). Data read directly from the Hbook file via THbookFile.

IMPORTANT NOTE When setting the branch address (via THbookTree::SetBranchAddress) for a branch in an Hbook block containing several names, eg Hbook block SELEVN with the following variables:

1 * R*4 * * * SELEVN * WGGS
2 * R*4 * * * SELEVN * AM12
3 * R*4 * * * SELEVN * AM34
4 * R*4 * * * SELEVN * AM14
5 * R*4 * * * SELEVN * AM32
6 * R*4 * * * SELEVN * PtPI(4)
7 * R*4 * * * SELEVN * PHIPI(4)
8 * R*4 * * * SELEVN * THTPI(4)
one must define a C struct like:
struct {
Float_t Wggs;
Float_t Am12;
Float_t Am34;
Float_t Am14;
Float_t Am32;
Float_t Ptpi[4];
Float_t Phipi[4];
Float_t Thtpi[4];
} event;
and set ONLY the first variable address with:
h96->SetBranchAddress("Wggs",&event.Wggs);
