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

Constructor & Destructor Documentation

AliEmcalTrackSelection::AliEmcalTrackSelection

(

)

Default consturctor, initialising objects with NULL, sets acception mode to ALL

Definition at line 30 of file AliEmcalTrackSelection.cxx.

AliEmcalTrackSelection::AliEmcalTrackSelection

(

const AliEmcalTrackSelection &

ref

)

Copy constructor, performing a flat copy

Parameters

ref

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
