Access to auxiliary data
Functions to retrieve attributes added to jet objects. They concern any attributes (float, vector<float>, 4-momentum,...) except IParticles (for the later see associatedParticles() function below). Access is done by an enum identifier or by string. They internally translate calls using double or vector<double> (ex: getAttribute<double>() ) in calls using float. This guarantees values are saved as float (less disk space) This avoids potential confusions related to retrieving a number as a float or as a double.

Access to the jet constituents. Constiuents are stored internally as IParticle. getConstituents() returns a special object : JetConstituentVector.

The JetConstituentVector behaves almost exactly as a simple vector<const IParticle*> AND guarantees that the 4-vectors it contains correpond to the 4-vector used at jet finding time.

Detailed Description

Class describing a jet.

Jet is a generic class used to represent any "types" of hadronic jet within the Atlas Software. The various "types" of jets include for example jets build from calorimeter cluster or from reconstructed tracks or from truth particle, etc... The Jet class provides 4 main features :

list of constituents. This list is build by the jet finding algorithm and is the physical definition of the jet object. Methods are provided to set and access constituents as IParticle objects.
4-momentum. Accessed through the inherited IParticle interface. A Jet 4-mom is not necessarily the sum of its constituents 4-mom (for ex. if a calibration has been applied).
Signal States : Jets can hold several other 4-momentum representing various calibration states (primarily used for calo jets). See also P4SignalState
Attributes : depending on its "type" several other attributes can be added to a jet.
- numbers, vector of numbers : access through the get/setAttribute functions
- other IParticles : dedicated functions are provided get/setAssociatedParticles (because of internal I/O details)

Assignment.

Parameters

other	The object from which we're assigning.
warnUnlocked	If true, then warn when we skip unlocked decorations.

We don't copy container/index, as assignment doesn't change where this object is. However, if we have aux data, then we copy aux data if we're copying from an object that also has it; otherwise, if we're copying from an object with no aux data, then we clear ours.

◆ setAssociatedObjects() [1/2]

template<typename T>

void xAOD::Jet_v1::setAssociatedObjects	(	AssoParticlesID	type,
		const std::vector< const T * > &	vec )

◆ setAssociatedObjects() [2/2]

template<typename T>

void xAOD::Jet_v1::setConstituentsSignalState ( JetConstitScale t )

Set the state at which constituents were when this jet was found. This function is called by jet builders.

Definition at line 141 of file Jet_v1.cxx.

◆ setConstStore()

void SG::AuxElement::setConstStore ( const SG::IConstAuxStore * store )

inherited

Synonym for setStore with IConstAuxStore.

Parameters

store The new store.

◆ setHadPrivateData()

void SG::IAuxElement::setHadPrivateData ( )

privateinherited

Record that this element used to have private data.

◆ setHavePrivateData()

void SG::IAuxElement::setHavePrivateData ( )

privateinherited

Record that this element currently has private data.

◆ setIndex()

void SG::AuxElement::setIndex	(	size_t	index,
		SG::AuxVectorData *	container )

privateinherited

Set the index/container for this element.

Parameters

index	The index of this object within the container.
container	The container holding this object. May be null if this object is being removed from a container.

Usually this simply sets the index and container members of this object. However, in the case where this object has an associated private store, then we need to deal with releasing the store if the object is being added to a container, or making a new store if the object is being removed from a container.

◆ setIndexPrivate()

bool SG::AuxElement::setIndexPrivate	(	size_t	index,
		SG::AuxVectorData *	container )

privateinherited

Set the index/container for this element.

Parameters

index	The index of this object within the container.
container	The container holding this object. May be null if this object is being removed from a container.

This is called from setIndex when we have a private store to deal with.

◆ m_container

const SG::AuxVectorData* SG::ConstAuxElement::m_container

The container of which this object is an element.

◆ m_fastJetLink

FastJetLinkBase* xAOD::Jet_v1::m_fastJetLink

Pointer to the fastjet object this jet is build from.

WARNING : this pointer is meant to be used in reco flow only. It is transient only, provided only to ease calculation of some jet quantities, and will be invalid for jets read from files.

Definition at line 346 of file Jet_v1.h.

◆ m_index

◆ supportsThinning

bool SG::AuxElement::supportsThinning = true

staticconstexprinherited

Mark that this type supports thinning operations.

See AthContainers/supportsThinning.h and AthenaPoolCnvSvc/T_AthenaPoolCnv.h. Helps guide which pool converter template will be used. If false, the default pool converter will be used rather than the aux store-specific one. Ordinary xAOD type should not touch this, but may be overridden in a derived class to handle certain special cases.
