Detailed Description

Class describing a truth particle in the MC record.

The xAOD truth record mimicks the structure of HepMC. Truth particles and truth vertices form a decay tree. Where each truth particle is connected to a single production and decay vertex. And each vertex is connected to one or more incoming, and one or more outgoing particles.

◆ setHadPrivateData()

Record that this element currently has private data.

◆ setIndex()

void SG::AuxElement::setIndex ( size_t  index,

)
privateinherited

Set the index/container for this element.

Parameters
indexThe index of this object within the container.
containerThe 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
indexThe index of this object within the container.
containerThe 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.

Parameters
valueThe polarization parameter value to set on the object
parameterThe polarization parameter type that we want to set
Returns
true if the operation was successful, or false if it wasn't

◆ 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.
