Detailed Description

A detector object made of other lower level object(s)

This class is intended to describe reconstruction objects coumpound of lower level detector objects. Typically it provides links to tracks and calo clusters such as is needed for particle flow objects.

The class is kept minimal and very generic so it can cover many use cases, including a generic type to describe jet constituents.

◆ assign()

void SG::AuxElement::assign	(	const AuxElement &	other,
		bool	warnUnlocked = false )

inherited

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.

◆ auxdata() [1/4]

template<class T, class ALLOC = AuxAllocator_t<T>>

Fetch an aux data variable, as a non-const reference.

Parameters

name	Name of the aux variable.

This method has to translate from the aux data name to the internal representation each time it is called. Using this method inside of loops is discouraged; instead use the Accessor class.

◆ copyAux()

void SG::AuxElement::copyAux	(	const ConstAuxElement &	other,

Copy aux data from another object.

Parameters

other	The object from which to copy.
warnUnlocked	If true, then warn when we skip unlocked decorations.

If this object has no associated store, this does nothing. If the associated aux data is const, this throws ExcConstAuxData.

All aux data items from other are copied to this object. Any aux data items associated with this object that are not present in other are cleared. (If other has no aux data, then all aux data items for this object are cleared.)

Parameters

container	Container of the element.
index	Index of this element within the container.
other	The object from which to copy.

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.

void xAOD::FlowElement_v1::setSignalType ( signal_t t )

◆ setStore() [1/3]

void SG::AuxElement::setStore ( const DataLink< 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.

Parameters

store Link to the new store.

Definition at line 269 of file AuxElement.cxx.

  if (store)
    data->setStore (store);

◆ 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.

Definition at line 241 of file AuxElement.cxx.

◆ setStore() [3/3]

void SG::AuxElement::setStore ( SG::IAuxStore * 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.

◆ setStore1()

AuxElementStandaloneData * SG::AuxElement::setStore1 ( const SG::IConstAuxStore * store )

privateinherited

Set the store associated with this object.

Parameters

store The new store.

Helper for setStore. Creates the AuxElementStandaloneData object if needed and returns it.

Parameters

store The new store.

Helper for setStore. Creates the @x AuxElementStandaloneData object if needed and returns it.

◆ setVertexType()

void xAOD::FlowElement_v1::setVertexType ( vertex_t t )

◆ signalType()

signal_t xAOD::FlowElement_v1::signalType ( ) const

Access signal type

◆ trackIndices()

bool SG::AuxElement::trackIndices ( ) const

inherited

Return true if index tracking is enabled for this object.

Always returns true. Included here to be consistent with AuxVectorBase when standalone objects may be used as template parameters.

◆ type()

Type::ObjectType xAOD::FlowElement_v1::type ( ) const

overridevirtual

The type of the object as a simple enumeration.

Implements xAOD::IParticle.

◆ usingPrivateStore()

◆ usingStandaloneStore()

◆ 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 335 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.

Definition at line 128 of file IAuxElement.h.

◆ m_privateStoreState

PrivateStoreState SG::IAuxElement::m_privateStoreState

privateinherited

Definition at line 137 of file IAuxElement.h.

◆ 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.
