Index of TREE/TREE

This directory contains all the basic classes for creating/manipulating Trees.

Several documents describing the TTree classes are listed below:

• The TTree data structure is documented in class TTree.
• The Chapter about Trees in the Users Guide
• The Chapter about Selectors in the Users Guide
• The Chapter about PROOF in the Users Guide
• The Chapter about IO in the Users Guide
• How to Create and Fill a Tree
• How to Read a Tree
• How to use Chains
