    • label

      public void label(javax.measure.Unit<?> unit, String label)
      Description copied from class: SimpleUnitFormat
      Attaches a system-wide label to the specified unit. For example: SimpleUnitFormat.getInstance().label(DAY.multiply(365), "year"); SimpleUnitFormat.getInstance().label(METER.multiply(0.3048), "ft"); If the specified label is already associated to an unit the previous association is discarded or ignored.
      Specified by:
      label in interface javax.measure.format.UnitFormat
      Specified by:
      label in class SimpleUnitFormat
      Parameters:
      unit - the unit being labeled.
      label - the new label for this unit.

    • alias

      public void alias(javax.measure.Unit<?> unit, String alias)
      Description copied from class: SimpleUnitFormat
      Attaches a system-wide alias to this unit. Multiple aliases may be attached to the same unit. Aliases are used during parsing to recognize different variants of the same unit. For example: SimpleUnitFormat.getInstance().alias(METER.multiply(0.3048), "foot"); SimpleUnitFormat.getInstance().alias(METER.multiply(0.3048), "feet"); SimpleUnitFormat.getInstance().alias(METER, "meter"); SimpleUnitFormat.getInstance().alias(METER, "metre"); If the specified label is already associated to an unit the previous association is discarded or ignored.
      Specified by:
      alias in class SimpleUnitFormat
      Parameters:
      unit - the unit being aliased.
      alias - the alias attached to this unit.

    • isValidIdentifier

      public boolean isValidIdentifier(String name)
      Description copied from class: SimpleUnitFormat
      Indicates if the specified name can be used as unit identifier.
      Specified by:
      isValidIdentifier in class SimpleUnitFormat
      Parameters:
      name - the identifier to be tested.
      Returns:
      true if the name specified can be used as label or alias for this format;false otherwise.
