Constructor & Destructor Documentation

TimeImpl::TimeImpl	(	int	n,
		G4double	t[],
		G4double	b[],
		G4double	e[] = 0
	)			[inline]

Constructor. n is # points in the arrays, t[] is the list of time values (ns), b[] and e[] are the factors for B field and E field. t[], b[], and e[] are copied so the caller can delete them after calling this routine.
