Member Function Documentation

string Wannier::getFilename	(	FilenameType	fnType,
		string	varName,
		int *	spin = `0`
	)		const

Get filename for varName, based on initFilename, dumpFilename or numericalOrbitalsFilename depending on fnType Optionally include Up/Dn suffix if spin is non-null and calculation is polarized
