Detailed Description

Implement virtual track selection for AOD analysis.

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

EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::AliEMCalPtTaskTrackSelectionAOD ( )

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

Definition at line 34 of file AliEMCalPtTaskTrackSelectionAOD.cxx.

EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::AliEMCalPtTaskTrackSelectionAOD	(	AliESDtrackCuts *	cuts,
		UInt_t	filterbits
	)

Main Constructor, initalising 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

cuts	Inital track cut object (of type AliESDtrackCuts, can be a nullpointer)
filterbits	Filter bits required

Definition at line 49 of file AliEMCalPtTaskTrackSelectionAOD.cxx.

EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::AliEMCalPtTaskTrackSelectionAOD ( const AliEMCalPtTaskTrackSelectionAOD & ref )

Copy constructor, performs a deep copy of the underlying track cuts (if reference object has those).

Parameters

ref	AOD track selection as basis for the copy

Definition at line 62 of file AliEMCalPtTaskTrackSelectionAOD.cxx.

EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::~AliEMCalPtTaskTrackSelectionAOD ( )

virtual

Destructor, removes the track cuts and the TObjArray of output tracks (if created)

Definition at line 92 of file AliEMCalPtTaskTrackSelectionAOD.cxx.

Member Function Documentation

void EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::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

filterbits

Definition at line 61 of file AliEMCalPtTaskTrackSelectionAOD.h.

TObjArray * EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::GetAcceptedTracks ( const TClonesArray *const tracks )

virtual

Select tracks from a list (TClonesArray) of tracks. The actual selection process is delegated to the function IsTrack selected. This function collects all the tracks which are accepted and puts them into a TObjArray. Note that this class keeps ownership over the resulting TObjArray.

Parameters

tracks TClonesArray of input tracks, under which we select the appropriate ones

Returns: TObjArray of selected tracks

Implements EMCalTriggerPtAnalysis::AliEMCalPtTaskVTrackSelection.

Definition at line 106 of file AliEMCalPtTaskTrackSelectionAOD.cxx.

TObjArray * EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::GetAcceptedTracks ( const AliVEvent *const event )

virtual

Select tracks from an input event. The actual selection process is delegated to the function IsTrack selected. This function collects all the tracks which are accepted and puts them into a TObjArray. Note that this class keeps ownership over the resulting TObjArray.

Parameters

event Input event under which we select the appropriate tracks

Returns: TObjArray of selected tracks

Implements EMCalTriggerPtAnalysis::AliEMCalPtTaskVTrackSelection.

Definition at line 126 of file AliEMCalPtTaskTrackSelectionAOD.cxx.

virtual TObject* EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::GetTrackCuts ( )

inlinevirtual

Get the track cuts.

Returns: The track cuts (NULL if not defined).

Implements EMCalTriggerPtAnalysis::AliEMCalPtTaskVTrackSelection.

Definition at line 53 of file AliEMCalPtTaskTrackSelectionAOD.h.

bool EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::IsTrackAccepted ( AliVTrack *const trk )

virtual

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

trk	Track to check

Returns: true if selected, false otherwise

AliEMCalPtTaskTrackSelectionAOD & EMCalTriggerPtAnalysis::AliEMCalPtTaskTrackSelectionAOD::operator= ( const AliEMCalPtTaskTrackSelectionAOD & ref )

Asignment operator, creates a deep copy of the track cuts(if set)
