Detailed Description

Interface for virtual track selection.

Interface for track selection within the EMCAL framework. Enables transparent track selection for ESDs and AODs by implementing a wrapper derived from this class. The following abstract functions need to be implemented by inheriting classes:

GetAcceptedTracks (with TClonesArray and AliVEvent as parameters)
IsTrackAccepted (with AliVTrackCuts)
GenerateTrackCuts

The usage of the virtual track selection is described here: VirtualTrackSelection

Member Enumeration Documentation

enum AliEmcalTrackSelection::ETrackFilterType_t

Pre-defined track filters.

Enumerator
kNoTrackFilter	No filter (all tracks passing)
kCustomTrackFilter	Custom (user-defined) tracks.
kHybridTracks	Hybrid tracks.
kTPCOnlyTracks	TPC-only tracks.

Constructor & Destructor Documentation

AliEmcalTrackSelection::AliEmcalTrackSelection ( )

Default consturctor.

Initialising objects with NULL, sets acception mode to ALL

Definition at line 29 of file AliEmcalTrackSelection.cxx.

AliEmcalTrackSelection::AliEmcalTrackSelection ( const AliEmcalTrackSelection & ref )

Copy constructor.

Performing a flat copy

Parameters

[in] ref

Definition at line 39 of file AliEmcalTrackSelection.cxx.

AliEmcalTrackSelection::~AliEmcalTrackSelection ( )

virtual

Destructor.

Deletes track and track cut arrays. In case the object has ownership over the track cuts itself, it also deletes those

void AliEmcalTrackSelection::AddTrackCuts ( AliVCuts * cuts )

Add new track cuts to the list of cuts.

Takes ownership over the cuts

Parameters

[in] cuts New cuts to add

Add new set of track cuts to the list of cuts.

Takes ownership over the cuts

Parameters

[in] cuts New set of cuts to add

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

pure virtual

Interface for track cut generators.

Track cut definitions might change period-by-period. Generators are methods to initialize the track cuts once the period is known. The method has default implementations for hybrid and global tracks.

As the way of implementation differs between ESDs and AODs the method has to be implemented in the child class.

Attention: In order to be usable for a given dataset, the initialization for the period / dataset needs to be implemented in the child class. Not all datasets are necessarily supported.

Parameters

[in]	type	Pre-defined track cuts type
[in]	period	Period / Dataset name for which to initialize the track cuts

Implemented in AliEmcalTrackSelectionAOD, and AliEmcalTrackSelectionESD.

const TClonesArray* AliEmcalTrackSelection::GetAcceptedTrackBitmaps ( ) const

inline

Get selection bitmaps of all accepted tracks

Returns: Bitmaps of all selected tracks

TObjArray * AliEmcalTrackSelection::GetAcceptedTracks ( const TClonesArray *const tracks )

Select tracks from a TClonesArray of input tracks.

Parameters

[in] tracks TClonesArray of tracks (must not be null)

Returns: TObjArray of selected tracks

Parameters

[in] event AliVEvent, via interface of virtual event (must not be null)

AliVCuts * AliEmcalTrackSelection::GetTrackCuts ( Int_t icut )

Access to track cuts at a given position.

Parameters

[in] icut Cut at position in array

Returns: The cuts (NULL for invalid positions)

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

pure virtual

Interface for track selection code.

This interface has to be implemented by the child classes. Here the selection of the track takes place. The function defines whether the track provided as argument is selected.

Attention: The function has to support both AliESD/AliAODtack on the one side and AliPicoTrack on the other side in order to be compatible with the old EMCAL framework.

Parameters

[in] trk Track to be checked
