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.

Parameters

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.

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.

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.

auxdecor() [2/2]

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

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

clearAux()

void SG::AuxElement::clearAux ( )

privateinherited

Clear all aux data associated with this element.

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

Definition at line 535 of file AuxElement.cxx.

{
  if (!m_container) return;
  if (!m_container->hasStore()) return;
  if (!m_container->hasNonConstStore())

  for (SG::auxid_t auxid : m_container->getWritableAuxIDs()) {
    r.clear (auxid, *container(), index(), 1);
  }
}

clearCache()

void SG::AuxElement::clearCache ( )

inherited

Clear the cached aux data pointers.

You should call this any time something changes in the aux store that could invalidate the vector pointers.

Definition at line 319 of file AuxElement.cxx.

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

clearDecorations()

bool SG::AuxElement::clearDecorations ( ) const

inherited

Clear all decorations.

Erase all decorations from an associated store, restoring the state to when lock was called.

Returns true if there were any decorations that were cleared, false if the store did not contain any decorations.

setConstStore()

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

inherited

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 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.

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.
