class AliMUONDataInterface: public TObject

 ctor
 @param filename should be the full path to a valid galice.root file

 dtor

 Return digitStore for a given event.
 Return 0x0 if event not found.
 Returned pointer should not be deleted

 \note If a previous store has been retrieved by one of the methods of
 this class, but for a different event number, then those stores will
 be deleted and no longer valid.
 If you require access to the data for the earlier retrieved store,
 but for different events, then you should deep copy / clone the object.

 Return clusterStore for a given event.
 Return 0x0 if event not found.
 Returned pointer should not be deleted

 \note If a previous store has been retrieved by one of the methods of
 this class, but for a different event number, then those stores will
 be deleted and no longer valid.
 If you require access to the data for the earlier retrieved store,
 but for different events, then you should deep copy / clone the object.

 Return the triggerStore for a given event.
 Return 0x0 if event not found.
 Returned pointer should not be deleted
 treeLetter can be R or D to tell from which tree to read the information

 Dump the digits for a given event, sorted if so required

 Dump the recpoints for a given event, sorted if so required

 Dump the given store, in sorted order

 Dump trigger for a given event from a given tree (if event>=0)
 or loop over all events and build a trigger ntuple if event<0
 treeLetter can be R or D to tell from which tree to read the information

 Loop over events to build trigger ntuples

 Load event if different from the current one.
 Returns kFALSE on error and kTRUE if the event was loaded.

 Number of events in the current galice.root file we're attached to

 Connect to a given galice.root file

 Loads all reconstructed data for the given event.

 Returns the number of digits to be found on a given detector element.
 @param detElemId  The detector element ID number to search on.

 Returns the a pointer to the index'th digit on the specified detector element.
 @param detElemId  The detector element ID number to search on.
 @param index  The index number of the digit to fetch in the range [0 .. N-1],
   where N = NumberOfDigits(detElemId)

 Returns the number of digits to be found on a specific chamber and cathode.
 @param chamber  The chamber number in the range [0 .. 13].
 @param cathode  The cathode in the range [0 .. 1], where 0 is the bending and
   1 is the non-bending plane.

 Returns the a pointer to the index'th digit on the specified chamber and cathode.
 @param chamber  The chamber number in the range [0 .. 13].
 @param cathode  The cathode in the range [0 .. 1], where 0 is the bending and
   1 is the non-bending plane.
 @param index  The index number of the digit to fetch in the range [0 .. N-1],
   where N = NumberOfDigits(chamber, cathode)

 Returns the number of reconstructed raw clusters on the specified chamber.
 @param chamber  The chamber number in the range [0 .. 13].

 Returns a pointer to the index'th raw cluster on the specified chamber.
 @param chamber  The chamber number in the range [0 .. 13].
 @param index  The index number of the raw cluster to fetch in the range [0 .. N-1],
   where N = NumberOfRawClusters(chamber)

 Returns the number of reconstructed local trigger objects.

 Returns a pointer to the index'th local trigger object.
 @param index  The index number of the local trigger object to fetch in the range [0 .. N-1],
   where N = NumberOfLocalTriggers()

 Returns the number of regional trigger objects reconstructed.

 Returns a pointer to the index'th regional trigger object.
 @param index  The index number of the regional trigger object to fetch in the range [0 .. N-1],
   where N = NumberOfRegionalTriggers()

 Returns a pointer to the reconstructed global trigger object for the event.

 Deletes all the store objects that have been created and resets the pointers to 0x0.
 The temporary iterator object is automatically reset. See ResetIterator for more details.

 Creates an appropriate iterator object and returns it.
 If the iterator has already been created then that one is returned otherwise
 a new object is created.
 Depending on the value of 'type' the semantics of parameters x and y can change.
 @param type  The type of iterator to create.
 @param x  This is the detector element ID if type == kDigitIteratorByDetectorElement
           If type equals kDigitIteratorByChamberAndCathode or kRawClusterIterator
           then this is the chamber number. In all other cases this parameter is
           ignored.
 @param y  If type == kDigitIteratorByChamberAndCathode then this parameter is the
           cathode number. In all other cases this parameter is
           ignored.

 The temporary iterator object is deleted if it exists and the pointer reset to 0x0.
 The iterator type and temporary data indicating the state of the iterator are
 also reset.

 Counts the number of objects in the iterator and resets it.
 @return The number of objects in 'iter'.

 Fetches the index'th object from the iterator counting the first object
 returned by iterator after it is reset as index == 0. The next object
 has index == 1 and so on where the last object returned by the iterator
 has index == N-1 where N = CountObjects(iter)
 This method will only reset the iterator if index is smaller than
 fCurrentIndex, which is used to track the iteration progress and is
 updated when a new object if returned by this method.
 @param iter  The iterator to fetch an object from.
 @param index The index number of the object to fetch in the range [0 .. N-1]
        where N = CountObjects(iter)

 Returns true if the data interface was able to open the root file correctly.

 Returns the index number of the current event loaded.
 This is the event number as was used in the last calls to DigitStore(Int_t),
 ClusterStore(Int_t), TriggerStore(Int_t) or GetEvent(Int_t).

 Dump the clusters for a given event, sorted if so required
