class AliCDBManager: public TObject

 returns AliCDBManager instance (singleton)

 factory registering

 initialize manager from existing cache
 used on the slaves in case of parallel reconstruction

 If singleKeys is true, dump the entries map and the ids list to the snapshot file
 (provided mostly for historical reasons, the file is then read with InitFromSnapshot),
 otherwise write to file each AliCDBEntry separately (the is the preferred way, the file
 is then read with SetSnapshotMode).

 The light snapshot does not contain the CDB objects (AliCDBEntries) but
 only the information identifying them, that is the map of storages and
 the list of AliCDBIds, as in the UserInfo of AliESDs.root

 initialize manager from a CDB snapshot, that is add the entries
 to the entries map and the ids to the ids list taking them from
 the map and the list found in the input file

 delete ALCDBManager instance and active storages

 default constuctor

 destructor

 put a storage object into the list of active storages

 add a storage factory to the list of registerd factories

 check if dbString is a URI valid for one of the registered factories

 create AliCDBParam object from URI string

 convert alien storage uri to local:///cvmfs storage uri (called when OCDB_PATH is set)

 Get the CDB storage corresponding to the URI string passed as argument
 If "raw://" is passed, get the storage for the raw OCDB for the current run (fRun)

 get storage object from AliCDBParam object

 get a storage object from the list of active storages

 return list of active storages
 user has responsibility to delete returned object

 set drain storage from URI string

 set drain storage from AliCDBParam

 set drain storage from another active storage

 drain retrieved object to drain storage

 Set the framework in official upload mode. This tells the framework to upload
 objects to cvmfs after they have been uploaded to AliEn OCDBs.
 It return false if the executable to upload to cvmfs is not found.

 sets default storage from URI string

 set default storage from AliCDBParam object

 set default storage from another active storage

 sets default storage for MC data
 mcString MUST be "MC",
 simType can be "Ideal","Residual","Full"

 The OCDB_PATH variable contains the path to the directory in /cvmfs/ which is
 an AliRoot tag based snapshot of the AliEn file catalogue (e.g.
 /cvmfs/alice.cern.ch/x86_64-2.6-gnu-4.1.2/Packages/OCDB/v5-05-76-AN).
 The directory has to contain:
 1) <data|MC>/20??.list.gz gzipped text files listing the OCDB files (seen by that AliRoot tag)
 2) bin/getOCDBFilesPerRun.sh   (shell+awk) script extracting from 1) the list
    of valid files for the given run.

 set default storage from the run number - to be used only with raw data

 set LHC period (year + first, last run) comparing run number and AliEn XML file

 set LHC period (year + first, last run) comparing run number and CVMFS file
 We don't want to connect to AliEn just to set the uri from the runnumber
 for that we use the script getUriFromYear.sh in the cvmfs AliRoot package

 Unset default storage

 sets storage specific for detector or calibration type (works with AliCDBManager::Get(...))

 sets storage specific for detector or calibration type (works with AliCDBManager::Get(...))
 Default storage should be defined prior to any specific storages, e.g.:
 AliCDBManager::instance()->SetDefaultStorage("alien://");
 AliCDBManager::instance()->SetSpecificStorage("TPC/*","local://DB_TPC");
 AliCDBManager::instance()->SetSpecificStorage("*/Align/*","local://DB_TPCAlign");
 calibType must be a valid CDB path! (3 level folder structure)
 Specific version/subversion is set in the uniqueid of the AliCDBParam value stored in the
 specific storages map

 get storage specific for detector or calibration type

 select storage valid for path from the list of specific storages

 get an AliCDBEntry object from the database
 RunNumber is not specified. Try with fRun

 get an AliCDBEntry object from the database!

 get an AliCDBEntry object from the database

 get the entry from the open snapshot file

 set the manager in snapshot mode

 return the URI of the storage where to look for path

 get the first run of validity
 for the current period
 if set

 get the last run of validity
 for the current period
 if set

 get the current LHC period string

 get the AliCDBId of the valid object from the database (does not retrieve the object)
 User must delete returned object!
 RunNumber is not specified. Try with fRun

 get the AliCDBId of the valid object from the database (does not retrieve the object)
 User must delete returned object!

 get the AliCDBId of the valid object from the database (does not retrieve the object)
 User must delete returned object!

 get multiple AliCDBEntry objects from the database
 RunNumber is not specified. Try with fRun

 get multiple AliCDBEntry objects from the database

 get multiple AliCDBEntry objects from the database
 Warning: this method works correctly only for queries of the type "Detector/*"
 		and not for more specific queries e.g. "Detector/Calib/*" !
 Warning #2: Entries are cached, but GetAll will keep on retrieving objects from OCDB!
 		To get an object from cache use Get() function

 store an AliCDBEntry object into the database

 store an AliCDBEntry object into the database

 set mirror Storage Elements for the default storage, if it is of type "alien"

 get mirror Storage Elements for the default storage, if it is of type "alien"

 cache AliCDBEntry. Cache is valid until run number is changed.

 Print list of active storages and their URIs

 Sets current run number.
 When the run number changes the caching is cleared.

 clear AliCDBEntry cache

 unload cached object
 that is remove the entry from the cache and the id from the list of ids

 delete list of active storages

 destroys active storage

 query default and specific storages for files valid for fRun. Every storage loads the Ids into its list.

 returns the name (string) of the data type

 Compare byte-by-byte the objects contained in the CDB entry in two different files,
 whose name is passed as input
 Return value:
   kTRUE - in case the content of the OCDB object (persistent part) is exactly the same
   kFALSE - otherwise

 Init the list of short-lived objects
 currently disabled

 returns the name (string) of the data type

 To lock/unlock user must provide the key. A new key is provided after
 each successful lock. User should always backup the returned key and
 use it on next access.
