◆ setStore() [2/3]

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

inherited

Set the store associated with this object.

Parameters

store The new store.

If store is nonzero, this adds a standalone store to the object. The object must not be in a container and must not have a private store. If store is zero, this removes a standalone store.

◆ 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

Definition at line 137 of file IAuxElement.h.

◆ 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.
