Detailed Description

Class describing one branch of the ROOT file.

This class describes a single, ROOT-readable branch of an xAOD file. It is used to figure out the hash <-> branch name associations, and which auxiliary branches belong to which auxiliary object.

This class doesn't have a "versioned name", as it is not meant to be written to a file directly, it should just be used as a transient means of storing data.
