Member Function Documentation

static bool code::W2Unit::convert	(	const std::string &	from,
		const std::string &	to,
		double	fromValue,
		double &	setmeToValue
	)			[static]

Convert a value from one unit to another.

Like value(), but returns a success flag to let callers know whether or not the conversion was successful.

static bool code::W2Unit::getConverter	(	const std::string &	from,
		const std::string &	to,
		UnitConverter &	setme
	)			[static]

Get a UnitConverter that converts from one unit to another.

static bool code::W2Unit::isCompatibleUnit	(	const std::string &	from,
		const std::string &	to
	)			[static]

static bool code::W2Unit::isValidUnit

(

const std::string &

unit

)

[static]

std::string code::W2Unit::unit

(

)

const [inline]

Return this W2Unit's units.

double code::W2Unit::value

(

)

const [inline]

Return this W2Unit's value in its native units.

bool code::W2Unit::value	(	const std::string &	units,
		double &	setme
	)			const [inline]

Convert the current W2Unit's value into other units.

Like value(string), but returns a success flag to let callers know whether or not the conversion was successful.

double code::W2Unit::value

(

const std::string &

units

)

const [inline]

Return this W2Unit's value in "units" units.

static double code::W2Unit::value	(	const std::string &	from,
		const std::string &	to,
		double	fromValue
	)			[static]

Convert a value from one unit to another.

See also:

convert()

static double code::W2Unit::value	(	const UnitConverter &	uc,
		double	d
	)			[inline, static]

Convert a value using a UnitConverter.
