◆ CheckParameters()

void BDSBunchEShell::CheckParameters ( )

virtual

Check the parameters for the given bunch distribution and exit if they're problematic or unphysical.

Each derived class can override this default method of reference position. If S0 > 0 or derived class changes member bool 'curvilinear' z0 will be treated as S and the global z0 be calculated.

		const G4double	beamlineS = `0`
	)

virtual

Extract and set the relevant options from the beam definition. The distribution type is explicitly required as this function may be used inside a nested bunch distribution. This argument is for the most part ignored, but there's no way to have a default for it. Also, some classes can cover multiple input distributions so need to know which one they're meant to be.
