Detailed Description

Base task in the EMCAL jet framework (lighter version of AliAnalysisTaskEmcalJet)

Author: Salvatore Aiola salva.nosp@m.tore.nosp@m..aiol.nosp@m.a@ce.nosp@m.rn.ch, Yale University

This class is the base class for Analysis Tasks using the core EMCAL jet framework. User tasks can choose to inherit from it as an alternative to AliAnalysisTaskEmcalJet. This class derives from AliAnalysisTaskEmcalLight and adds some additional features, useful for jet analysis. The key feature is the handling of the jet containers.

Constructor & Destructor Documentation

AliAnalysisTaskEmcalJetLight::AliAnalysisTaskEmcalJetLight ( )

Default constructor (should only be used by ROOT I/O).

Definition at line 39 of file AliAnalysisTaskEmcalJetLight.cxx.

AliAnalysisTaskEmcalJetLight::AliAnalysisTaskEmcalJetLight	(	const char *	name,
		Bool_t	histo = `kFALSE`
	)

Standard constructor. Should be used by the user.

Note: This constructor also handles the general histograms. In case the second parameter is true, then general histograms (see UserCreateOutputObjects and FillHistograms) are created and filled by the task, and a container is provided handling the user histograms.

Parameters

[in]	name	Name of the task
[in]	histo	If true then general histograms are filled by the task

		UInt_t	accType,
		AliParticleContainer *	partCont,

		TString	tag = `"Jet"`
	)

Create new jet container and attach it to the task. This method is usually called in the add task macro.

Parameters

[in]	jetType	One of the AliJetContainer::EJetType_t enumeration values (charged, full, neutral)
[in]	jetAlgo	One of the AliJetContainer::EJetAlgo_t enumeration values (anti-kt, kt, ...)
[in]	recoScheme	One of the AliJetContainer::ERecoScheme_t enumeration values (pt-scheme, ...)
[in]	radius	Resolution parameter (0.2, 0.4, ...)
[in]	accType	One of the AliEmcalJet::JetAcceptanceType enumeration values (TPC, EMCAL, user, ...)
[in]	partCont	Particle container of the objects used to generate the jets
[in]	clusCont	Cluster container of the objects used to generate the jets
[in]	tag	Label to distinguish different jet branches (defaul is 'Jet')

Returns: Pointer to the new jet container

void AliAnalysisTaskEmcalJetLight::AdoptJetContainer ( AliJetContainer * cont )

inline

Definition at line 44 of file AliAnalysisTaskEmcalJetLight.h.

void AliAnalysisTaskEmcalJetLight::ExecOnce ( )

protectedvirtual

Perform steps needed to initialize the analysis. This function relies on the presence of an input event (ESD or AOD event). Consequently it is called internally by UserExec for the first event.

This function connects all containers attached to this task to the corresponding arrays in the input event. Furthermore it initializes the geometry.

Reimplemented from AliAnalysisTaskEmcalLight.

AliJetContainer * AliAnalysisTaskEmcalJetLight::GetJetContainer ( Int_t i = 0 ) const

Get \( i^{th} \) jet container attached to this task

Parameters

[in] i Index of the jet container
