Constructor & Destructor Documentation

◆ BDSPrimaryGeneratorFileSampler()

BDSPrimaryGeneratorFileSampler::BDSPrimaryGeneratorFileSampler	(	const G4String &	distrType,
		const G4String &	fileNameIn,
		BDSBunchEventGenerator *	bunchIn,
		G4bool	loopFileIn,
		G4bool	removeUnstableWithoutDecayIn = `true`,
		G4bool	warnAboutSkippedParticlesIn = `true`
	)

Constructor takes full distrType string including semicolon and eventgeneratorfile prefix. The filename is assumed to be correctly prefixed if a relative path already. The bunch definition is used for the reference coordinates and offset of the beam point.
