public class MeasureFormat
extends UFormat

A formatter for Measure objects.

IMPORTANT: New users are strongly encouraged to see if NumberFormatter fits their use case. Although not deprecated, this class, MeasureFormat, is provided for backwards compatibility only, and has much more limited capabilities.

To format a Measure object, first create a formatter object using a MeasureFormat factory method. Then use that object's format or formatMeasures methods. Here is sample code:

 MeasureFormat fmtFr = MeasureFormat.getInstance(ULocale.FRENCH, FormatWidth.SHORT);
 Measure measure = new Measure(23, MeasureUnit.CELSIUS);

 // Output: 23 °C
 System.out.println(fmtFr.format(measure));

 Measure measureF = new Measure(70, MeasureUnit.FAHRENHEIT);

 // Output: 70 °F
 System.out.println(fmtFr.format(measureF));

 MeasureFormat fmtFrFull = MeasureFormat.getInstance(ULocale.FRENCH, FormatWidth.WIDE);
 // Output: 70 pieds et 5,3 pouces
 System.out.println(fmtFrFull.formatMeasures(new Measure(70, MeasureUnit.FOOT),
         new Measure(5.3, MeasureUnit.INCH)));

 // Output: 1 pied et 1 pouce
 System.out.println(
         fmtFrFull.formatMeasures(new Measure(1, MeasureUnit.FOOT), new Measure(1, MeasureUnit.INCH)));

 MeasureFormat fmtFrNarrow = MeasureFormat.getInstance(ULocale.FRENCH, FormatWidth.NARROW);
 // Output: 1′ 1″
 System.out.println(fmtFrNarrow.formatMeasures(new Measure(1, MeasureUnit.FOOT),
         new Measure(1, MeasureUnit.INCH)));

 MeasureFormat fmtEn = MeasureFormat.getInstance(ULocale.ENGLISH, FormatWidth.WIDE);

 // Output: 1 inch, 2 feet
 fmtEn.formatMeasures(new Measure(1, MeasureUnit.INCH), new Measure(2, MeasureUnit.FOOT));
 

This class does not do conversions from one unit to another. It simply formats whatever units it is given

This class is immutable and thread-safe so long as its deprecated subclass, TimeUnitFormat, is never used. TimeUnitFormat is not thread-safe, and is mutable. Although this class has existing subclasses, this class does not support new sub-classes.
