Method Detail

getQuantity

public static ComparableQuantity<?> getQuantity(CharSequence csq)

Returns the decimal measure of unknown type corresponding to the specified representation. This method can be used to parse dimensionless quantities.
Quantity proportion = Quantities.getQuantity("0.234").asType(Dimensionless.class);

Note: This method handles only standard unit format (UCUM based). Locale-sensitive measure formatting and parsing are handled by the MeasurementFormat class and its subclasses.

Parameters:

csq - the decimal value and its unit (if any) separated by space(s).

Returns:

QuantityFormat.getInstance(LOCALE_NEUTRAL).parse(csq, new ParsePosition(0))

Returns the scalar measurement. When the Number was BigDecimal or BigInteger will uses DecimalQuantity, when the Number was Double will DoubleQuantity otherwise will NumberQuantity. in the specified unit.

Parameters:

value - the measurement value.

unit - the measurement unit.

Returns:

the corresponding numeric measurement.

Throws:

NullPointerException - when value or unit were null
