Detailed Description

The ExtrapolatorTest 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 is the TestAlgorithm for 'the' Extrapolator instance provided to client algorithms.

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.

Declare a new Gaudi property.

Parameters

Override sysInitialize.

Override sysInitialize from the base class.

Loop through all output handles, and if they're WriteCondHandles, automatically register them and this Algorithm with the CondSvc
