Detailed Description

Access to a MC data branch for time-based analysis.

Author: //Dr.Sys mikha.nosp@m.il.p.nosp@m.rokud.nosp@m.in@c.nosp@m.ern.c.nosp@m.h

Date: 31 March 2015

This class provides cached access to data for an event-by-event MC data branch, which is used when matching time-based reconstruction data to the input MC data. Data arrays from already used events are cached, which allows switching between events without the performance deterioration induced by frequent calls to TTree::GetEntry(). In legacy mode, the data from the current event will be retrieved from FairRootManager.
