Detailed Description

The ExtrapolatorComparisonTest Algorithm runs a number of n test extrapolations from randomly distributed Track Parameters to reference surfcas within.

• a) the Inner Detector if DetFlags.ID_On()
• b) the Calorimeter if DetFlags.Calo_On()
• c) the Muon System if DetFlags.Muon_On()

It uses and compares the output obtaining using the ATLAS Extrapolator and the ACTS Extrapolation

inputHandles()

virtual std::vector< Gaudi::DataHandle * > AthCommonDataStore< AthCommonMsg< Gaudi::Algorithm > >::inputHandles ( ) const

isClonable()

virtual bool AthCommonAlgorithm< Gaudi::Algorithm >::isClonable ( ) const

inlineoverridevirtualinherited

Specify if the algorithm is clonable.

Only relevant for non-reentrant algorithms. Actual number of clones needs to be set via the "Cardinality" property.
