◆ 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>>

XAOD_AUXDATA_DEPRECATED Accessor<T, ALLOC>::reference_type SG::AuxElement::auxdata ( const std::string & name )

inherited

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.

◆ auxdata() [2/4]

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

XAOD_AUXDATA_DEPRECATED Accessor<T, ALLOC>::const_reference_type SG::AuxElement::auxdata ( const std::string & name ) const

inherited

Fetch an aux data variable, as a 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 or ConstAccessor classes.

◆ auxdata() [3/4]

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

XAOD_AUXDATA_DEPRECATED Accessor<T, ALLOC>::reference_type SG::AuxElement::auxdata	(	const std::string &	name,
		const std::string &	clsname
	)

inherited

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

Parameters

name	Name of the aux variable.
clsname	The name of the associated class. May be blank.

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.

◆ auxdata() [4/4]

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

XAOD_AUXDATA_DEPRECATED Accessor<T, ALLOC>::const_reference_type SG::AuxElement::auxdata	(	const std::string &	name,
		const std::string &	clsname
	)		const

inherited

Fetch an aux data variable, as a const reference.

Parameters

name	Name of the aux variable.
clsname	The name of the associated class. May be blank.

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 or ConstAccessor classes.

◆ auxdataConst() [1/2]

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

XAOD_AUXDATA_DEPRECATED Accessor<T, ALLOC>::const_reference_type SG::AuxElement::auxdataConst ( const std::string & name ) const

inherited

Fetch an aux data variable, as a 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 ConstAccessor class.

	)		const

inherited

Fetch an aux data variable, as a const reference.

Parameters

name	Name of the aux variable.
clsname	The name of the associated class. May be blank.

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 ConstAccessor class.

inherited

Fetch an aux decoration, 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.

If the container is locked, this will allow fetching only variables that do not yet exist (in which case they will be marked as decorations) or variables already marked as decorations.

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.

Definition at line 335 of file AuxElement.h.

◆ m_index

The index of this element within its container.

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

◆ 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.
