39 // 20-Jul-2011 M.Kelsey -- null-pointer checks in DumpState()
40 // 24-Sep-2011 M.Kelsey -- Use envvar G4HADRONIC_RANDOM_FILE to save random
41 // engine state before each model call
42 // 18-Oct-2011 M.Kelsey -- Handle final-state cases in conservation checks.
43 // 14-Mar-2012 G.Folger -- enhance checks for conservation of energy, etc.
44 // 28-Jul-2012 M.Maire -- add function GetTargetDefinition()
45 // 14-Sep-2012 Inherit from RestDiscrete, use subtype code (now in ctor) to
46 // configure base-class
47 // 28-Sep-2012 Restore inheritance from G4VDiscreteProcess, remove enable-flag
48 // changing, remove warning message from original ctor.
