Detailed Description

Class holding file-level metadata about an xAOD file.

Each xAOD file is expected to hold exactly one object of this type to describe much of the simple metadata about the file. So, metadata that might change event-by-event in the file is not stored in such objects.

Member Function Documentation

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.

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.

container	Container of the element.
index	Index of this element within the container.

If the associated aux data is const, this throws ExcConstAuxData.

    r.clear (auxid, container, index, 1);
  }
}

clearCache()

{
  if (container())
    container()->clearCache();
}

clearDecorations()

bool SG::AuxElement::clearDecorations ( ) const

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

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.

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

The index of this element within its container.

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

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.
