Detailed Description

Algorithm to skim the xAOD truth particle container for tau filter.

This algorithm is used to copy and skim the particles from the xAOD TruthParticles container, keeping just relevant taus from the event.
The design of this class heavily mirrors the DerivationFramework::TruthCollectionMaker.

Parameters

doc	Documentation string for the property.

This is the version for types that derive from SG::VarHandleBase. The property value object is put on the input and output lists as appropriate; then we forward to the base class.

inlineinherited

Declare a new Gaudi property.

Parameters

name	Name of the property.
property	Object holding the property value.
doc	Documentation string for the property.

This is the generic version, for types that do not derive from SG::VarHandleKey. It just forwards to the base class version of declareProperty.

sysStart()

virtual StatusCode AthCommonDataStore< AthCommonMsg< Algorithm > >::sysStart ( )

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.
