Detailed Description

Class performing the selection of triggered events.

This class generates a trigger decision for an event for the given EMCAL trigger class. The decision can come either from trigger patches or trigger strings. For the trigger decision from patches also an energy threshold can be applied. The trigger decision is done in the function Create, which builds the decision for both patches and trigger string. The event selection, done using the function IsTriggerd, can come from the patches, from the string, or from both at the same time. Note that different selection modes need to run in data and Monte-Carlo since in Monte- Carlo trigger strings do not exists, and in data the trigger is already applied at hardware level.

Member Function Documentation

bool EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::CheckConsistency ( ) const

Check whether the trigger decision from the trigger strings and the trigger patches are the same

Returns: result of the comparison

Definition at line 79 of file AliEMCalTriggerAnaTriggerDecision.cxx.

Referenced by SetDebugMode().

void EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::ConfigureTriggerDecision ( const AliEMCalTriggerAnaTriggerDecisionConfig & conf )

inline

Set the configuration used for the trigger selection.

Parameters

conf	Configuration used for the trigger selection

void EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::Create ( const AliEMCalTriggerEventData *const data )

Steer creation of the trigger decision. Delegates the creation of the trigger decision from trigger strings to the function MakeDecisionFromString and of the decision from patches to the function MakeDecisionFromPatches.

Parameters

data	all event information

const AliEMCalTriggerAnaTriggerDecisionConfig* EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::GetConfiguration ( ) const

inline

Get the trigger decision configuration

Returns: the trigger decision configuration

Double_t EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::GetPatchEnergy	(	EPatchEnergyType_t	energytype,
		const AliEMCALTriggerPatchInfo *const	patch
	)		const

protected

Retrieve patch energy from the reconstruced patch according to the energy definition specified.

Parameters

energytype	Energy type
patch	The reconstructed patch

Returns: The patch energy

Bool_t EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::IsTriggered	(	ETATriggerType	trigger,
		ETriggerMethod_t	method = `kTriggerString`
	)		const

inline

Apply event selection using a given trigger class. Three methods are avialable:

Using the trigger string (kTriggerString)
Using the reconstructed patches, online or offline (kTriggerPatches)
Using patches and trigger string (kTriggerMixed): In this case both conditions need to be fulfilled

Parameters

trigger	Type of the trigger requested in order to select the event
method	Method (see above) used for the event selection

Returns: True if event is selected as triggered event, false otherwise

void EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::MakeDecisionFromPatches ( const TClonesArray & listOfPatches )

protected

Create trigger decision from trigger patches. In case swap thresholds is requested, the low threshold triggers are replaced by the high threshold triggers and vice versa

Parameters

listOfPatches the TClonesArray of the trigger patches, created by the trigger patch maker

void EMCalTriggerPtAnalysis::AliEMCalTriggerAnaTriggerDecision::MakeDecisionFromString ( const TString & triggerstring )

protected

Create trigger decision from trigger string. For each trigger class we only check if the name of the trigger class appears in the trigger string.

Parameters

triggerstring the trigger string stored in the reconstructed event.
