Detailed Description

This is a helper class for adding and filling branches to a tree.

If the tree doesn't already exist, a new one is created in memory and made friend with the input TMBTree. The tree can be written to file using the default Write processor in cafe.

Usage:

In your processor:

_treehandler = new TreeHandler();

_treehandler->InitTree("TreeName",file); _treehandler->AddBranch("Branch1",... _treehandler->AddBranch("Branch2",...

_treehandler->FillBranch("Branch1",myCollection1) _treehandler->FillBranch("Branch2",myCollection2)

_treehandler->ClearIt();
