Detailed Description

Description: ROOT specific implementation of Database container. Since objects in root are stored in "trees with branches", this object corresponds to a tuple (Tree/Branch), where each object type (determined by the location of the transient object within the data store) is accessed by the "Event" number inside its tree.
