AliEmcalAODFilterBitCuts implements the track filter bit selection of AOD tracks within the framework of virtual cuts. This means that in filters it can be used as any virtual cut class. Like this no special treatment is for AOD filter bit selection.

The cut is applied in the function

AliEmcalAODFilterBitCuts::IsSelected(TObject *o);

which needs to be called in any filter with the AOD track as argument.

The filter allows two selection modes:

• Any: at least one of the bits needs to be found
• All: all bits need to be found.

Member Enumeration Documentation

enum AliEmcalAODFilterBitCuts::SelectionMode_t

Enumerator
kSelAny	Any (either of the bits set)
kSelAll	All (all bits must be found in the AOD track)

Member Function Documentation

void AliEmcalAODFilterBitCuts::AddFilterBitNumber ( ULong_t  bitnumber )

inline

Request filter bit at a given bit number (not bit representation).

Parameters

[in]

bitnumber

Number of the bit to be set (integer number)

Definition at line 60 of file AliEmcalAODFilterBitCuts.h.

Bool_t AliEmcalAODFilterBitCuts::IsSelected ( TObject *  o )

virtual

Select AOD tracks according which contain any of the bits. The way of the selection is determined by the selection mode (default: any):

• Any: At least one bit needs to be found
• All: All bits must be found

Parameters

[in]

o

Object to be checked: Must be an AliAODTrack

Returns

True if object is selected. Always false in case object is not an AliAODTrack

Definition at line 29 of file AliEmcalAODFilterBitCuts.cxx.

void AliEmcalAODFilterBitCuts::SetFilterBits ( ULong_t  filterbits )

inline

Set the filter bits to be checked. Function using the bit representation, not the number of then bit.

Parameters

[in]

filterbits

Filter bits requested

Definition at line 67 of file AliEmcalAODFilterBitCuts.h.
