class AliTRDcalibDB: public TObject

 Singleton implementation
 Returns an instance of this class, it is created if neccessary

 Singleton implementation
 Deletes the instance of this class and sets the terminated flag,
 instances cannot be requested anymore
 This function can be called several times.

 Default constructor

 TODO Default runnumber is set to 0, this should be changed later
      to an invalid value (e.g. -1) to prevent
 TODO invalid calibration data to be used.

 Copy constructor (not that it make any sense for a singleton...)

 Assignment operator (same as above ...)

 Retrieves a cdb object with the given id. The objects are cached as
 long as the run number is not changed.

 Put together the available objects here by using the lines
   a) For usual calibration objects:
      case kID<Name> :
        return CacheCDBEntry(kID<Name>,"TRD/Calib/<Path>");
        break;
      See function CacheCDBEntry for details.
   and
   b) For calibration data which depends on two objects: One containing
      a value per detector and one the local fluctuations per pad:
      case kID<Name> :
        return CacheMergeCDBEntry(kID<Name>,"TRD/Calib/<padPath>","TRD/Calib/<chamberPath>");
        break;
      See function CacheMergeCDBEntry for details.

 Retrieves an entry with path <cdbPath> from the CDB.

 Caches the entry <id> with cdb path <cdbPath>

 Sets current run number. Calibration data is read from the corresponding file.
 When the run number changes the caching is invalidated.

 Invalidates cache (when run number is changed).

 Returns the noise level in ADC counts for the given pad.

 Returns the Vdrift calibration object for a given ROC
 containing one number per pad

 Returns the Vdrift calibration object
 containing one number per detector

 Returns the drift velocity for the given pad.

 Returns the Vdrift calibration object for a given ROC
 containing one number per pad

 Returns the Vdrift calibration object
 containing one number per detector

return PHQ calibration object

 Returns the average drift velocity for the given detector

 Returns the exB calibration object
 containing one number per detector

 Returns t0 for the given pad.

 Returns the t0 calibration object for a given ROC
 containing one number per pad

 Returns the t0 calibration object
 containing one number per detector

 Returns the average t0 for the given detector

 Returns the online gain factor table for a given ROC.

 Returns the online gain factor for the given pad.

 Returns the gain factor calibration object for a given ROC

 Returns the gain factor for the given pad.

 Returns the gain factor calibration object
 containing one number per detector

 Returns the average gain factor for the given detector

 Returns the PRF calibration object for a given ROC
 containing one number per pad

 Returns the PRF width for the given pad.

 Check if there is any content in the string first

 This is an old way to extract the number of time bins,
 only to be used as a fallback to see whether there's
 a patched OCDB object!

 Returns number of time bins from the DCS

 Returns the filter type

 Get the gain table ID from the DCS

 Get Configuration from the DCS

 Get Configuration from the DCS

 Get Version of Configuration from the DCS

 Get the number of configuration parameters from the DCS config

 Get the number of options of a given configuration parameter from DCS

 Get a configuration (see enum in header file) or the options of a configuration
 option == 0 returns the configuration itself
 option >  0 returns the optional parameter Nr. (option) of the configuration (cfgType)

 Checks whether pedestal filter was applied online

 Checks whether online gain filter was applied

 Checks whether online tail cancellation was applied

 Returns the status of the given pad

 Returns the pad status calibration object for a given ROC

 Returns the status of the given chamber

 Returns the TRD reconstruction parameters from the OCDB

 Returns status, see name of functions for details ;-)

 Returns the object storing the distributions for PID with likelihood

 Returns the PID response object for 1D-LQ

 Returns the object storing likelihood distributions for cluster to track attachment

 Returns the object storing the monitoring data

 Samples the pad response function (should maybe go somewhere else ...)

 Applies the pad response
 So far this is the fixed parametrization and should be replaced by
 something dependent on calibration values

 return an existing TRAPconfig or load it from the OCDB
 in case of failure, a default TRAPconfig is created

 try to load the specified configuration from the OCDB
 if it fails, or it does not exist, return null
