Returns

identification number of the algorithm used to reconstruct the track (see xAOD::AFPTrackRecoAlgID )

Parameters

newIAlgID

identification number of the algorithm used to reconstruct the track

setChi2()

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.

Member Data Documentation

m_container

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

privateinherited

The container of which this object is an element.

Should be null if this object is not within a container, except that it may also point at a private store.

Definition at line 324 of file AuxElement.h.

m_index

size_t SG::IAuxElement::m_index

privateinherited

The index of this element within its container.

Should be 0 if this object is not within a container.

PrivateStoreState SG::IAuxElement::m_privateStoreState

privateinherited

supportsThinning

constexpr 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.
