Algorithm to skim the xAOD truth particle container for xAOD electron 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
-
name | Name of the property. |
hndl | Object holding the property value. |
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.

◆ declareProperty() [2/6]
Declare a new Gaudi property.
- Parameters
-
name | Name of the property. |
hndl | Object holding the property value. |
doc | Documentation string for the property. |
This is the version for types that derive from SG::VarHandleKey
. The property value object is put on the input and output lists as appropriate; then we forward to the base class.

◆ declareProperty() [3/6]
◆ declareProperty() [4/6]
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
.
Definition at line 333 of file AthCommonDataStore.h.
338 return PBASE::declareProperty(
name, property,
doc);
◆ declareProperty() [5/6]
Declare a new Gaudi property.
- Parameters
-
name | Name of the property. |
property | Object holding the property value. |
doc | Documentation string for the property. |
This dispatches to either the generic declareProperty
or the one for VarHandle/Key/KeyArray.
