Implementation of track selection in case the analysis runs on AODs For the moment it uses the AliESDtrackCuts and converts AOD tracks to ESD tracks, which might change in the future when an AOD track selection framework becomes available.

Constructor & Destructor Documentation

AliEmcalTrackSelectionAOD::AliEmcalTrackSelectionAOD ( )

Main constructor.

Initializes fields with 0 (or NULL). For ROOT I/O, not intended to be used by the users.

Definition at line 30 of file AliEmcalTrackSelectionAOD.cxx.

AliEmcalTrackSelectionAOD::AliEmcalTrackSelectionAOD ( ETrackFilterType_t  type,
const char *  period = "" 
)

Constructor for periods.

Initializing track cuts depending on the requested type of filtering

Parameters
[in]typeTrack filtering type
[in]periodPeriod string (e.g. LHC11h)

Definition at line 51 of file AliEmcalTrackSelectionAOD.cxx.

AliEmcalTrackSelectionAOD::AliEmcalTrackSelectionAOD ( AliVCuts *  cuts,
UInt_t  filterbits 
)

Main Constructor.

Initalizing also track cuts and filter bits. In case the initial cuts is a nullpointer, only filter bits are used for the track selection. This constructor is intended to be used by the users.

Parameters
[in]cutsInital track cut object (of type AliESDtrackCuts, can be a nullpointer)
[in]filterbitsFilter bits required

Definition at line 40 of file AliEmcalTrackSelectionAOD.cxx.

virtual AliEmcalTrackSelectionAOD::~AliEmcalTrackSelectionAOD ( )
inlinevirtual

Destructor.

Definition at line 59 of file AliEmcalTrackSelectionAOD.h.

Member Function Documentation

void AliEmcalTrackSelectionAOD::AddFilterBit ( UInt_t  filterbits)
inline

Add a new filter bit to the track selection.

Multiple filter bits can be set at the same time (via the bitwise or operator |).

Parameters
filterbitsFilter bits used to select tracks

void AliEmcalTrackSelectionAOD::GenerateTrackCuts ( ETrackFilterType_t  type,
const char *  period = "" 
)
virtual

Automatically generates track cuts depending on the requested type of filtering.

Parameters
[in]typeTrack filtering type

Implements AliEmcalTrackSelection.

Bool_t AliEmcalTrackSelectionAOD::GetHybridFilterBits ( Char_t  bits[],
TString  period 
)
static

Returns the hybrid filter bits according to a hard-coded look-up table.

Parameters
[in]bitsc-array of 2 elements where the bits are returned
[in]perioddata taking period
Returns
true if successful, false otherwise

Definition at line 149 of file AliEmcalTrackSelectionAOD.cxx.

Referenced by GenerateTrackCuts().

bool AliEmcalTrackSelectionAOD::IsTrackAccepted ( AliVTrack *const  trk)
virtual

Performing track selection.

Function checks whether track is accepted under the given track selection cuts. The function can handle AliAODTrack and AliPicoTrack, while for AliPico track an AliAODTrack is expected to be the underlying structure. If it is not possible to access an AOD track from the input track, the object will not be selected. Otherwise first the status bits are checked (if requested), and if further track cuts (of type AliESDtrackCuts) are provided, the track is converted to an ESD track for further checks.

Parameters
[in]trkTrack to check
Returns
true if selected, false otherwise

Implements AliEmcalTrackSelection.

Definition at line 88 of file AliEmcalTrackSelectionAOD.cxx.
