class TTreePlayer: public TVirtualTreePlayer


TTreePlayer

A TTree object is a list of TBranch.
To Create a TTree object one must:
- Create the TTree header via the TTree constructor
- Call the TBranch constructor for every branch.

To Fill this object, use member function Fill with no parameters.
The Fill function loops on all defined TBranch.
