Detailed Description

This is the ALFA Beam Transport package. It is an interface which uses FPTracker for beamtransportation. Getting from the HepMC eventrecord the particle data at the IP it calculates the particle porition at the first RP.

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.
