Constructor & Destructor Documentation

BDSROOTSamplerReader()

BDSROOTSamplerReader::BDSROOTSamplerReader	(	const G4String &	distrType,
		const G4String &	fileNameIn,
		BDSBunchEventGenerator *	bunchIn,
		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.

anyParticlesFoundAtAll

G4bool BDSROOTSamplerReader::anyParticlesFoundAtAll

private

We need to keep a note of if we find any particles at all when looping through a file so we can distinguish if the whole file had no particles, or say the last event doesn't before we loop through the file again.
