40 *
41 * Helper class that can be employed in the fast simulation models.
42 * It allows to deposit energy at given position (G4FastHit), provided it is
43 * located within the sensitive detector that derives from
44 * G4VFastSimSensitiveDetector base class.
45 * An extended example extended/parameterisations/Par03 demonstrates how to use
46 * G4FastSimHitMaker to create multiple deposits from the fast simulation model.
