22 // For every detector in AliShuttleConfgi (see AliShuttleConfig),
23 // data for its set of aliases is retrieved. If there is registered
24 // AliPreprocessor for this detector then it will be used

27 // data is stored automatically to the undelying AliCDBStorage.
28 // For detSpec is used the alias name.
