class AliAlignmentTracks: public TObject

 Default constructor

 Constructor in the case
 the user provides an already
 built TChain with ESD trees

 Constructor in the case
 the user provides a single ESD file
 or a directory containing ESD files

 Destructor

 Add a chain with ESD files

 Add a single file or
 a directory to the chain
 with the ESD files

 Analyzes and filters ESD tracks
 Stores the selected track space points
 into the output file

 Analyzes and filters ESD tracks
 Merges inward and outward tracks in one single track
 Stores the selected track space points
 into the output file

 Build index of points tree entries
 Used for access based on the volume IDs

 Initialize the index arrays

 Reset the value of the last filled index
 Do not realocate memory

 Delete the index arrays
 Called by the destructor

 Read alignment object from a file: update the alignobj already present with the one in the file
 To be replaced by a call to CDB

 Initialize the alignment objects array

 Reset the alignment objects array

 Delete the alignment objects array

 Align detector volumes within
 a given layer range
 (could be whole detector).
 Tracks are fitted only within
 the range defined by the user.

 Align detector volumes within
 a given layer.
 Tracks are fitted only within
 the range defined by the user.

 Align single detector volume to
 another volume.
 Tracks are fitted only within
 the second volume.

 Align a set of detector volumes.
 Tracks are fitted only within
 the range defined by the user
 (by layerRangeMin and layerRangeMax)
 or within the set of volidsfit
 Repeat the procedure 'iterations' times

 Load track point arrays with at least
 one space point in a given set of detector
 volumes (array volids).
 Use the already created tree index for
 fast access.

 Unload track point arrays for a given
 detector volume

 Check if the user has already supplied
 a track fitter object.
 If not, create a default one.

 Check if the user has already supplied
 a track residuals minimizer object.
 If not, create a default one.

 The method reads from a file a set of AliAlignObj which are
 then used to apply misalignments directly on the track
 space-points. The method is supposed to be used only for
 fast development and debugging of the alignment algorithms.
 Be careful not to use it in the case of 'real' alignment
 scenario since it will bias the results.
