Detailed Description

Class managing the serialization of event ID in a simple ROOT tree.

The tree is supplied by the caller. This object will create the proper branches into the tree and assign addresses to them. Then it will assume they will stay assigned.

On assignEvent(), the branch addresses are assigned the values from the event ID. The tree is not Fill()-ed.

The tree structure is: Run/i:SubRun/i:Event/i, with a single branch per element.
