20 * @class AliHLTOnlineESDtrack
21 * @brief Container for AliESDtrack information relevant for HLT.
22 *
23 * The class implements a reduced set of member variables of AliESDtrack
24 * and corresponding transformation functions and operators.
25 * It is used by the custom streamer of AliHLTESDEvent.
