  • Method Details

    • parseForIdentifier

      public static MeasureUnitImpl parseForIdentifier(String identifier)
      Construct a MeasureUnit from a CLDR Unit Identifier, defined in UTS 35. Validates and canonicalizes the identifier.
      Returns:
      MeasureUnitImpl object or null if the identifier is empty.
      Throws:
      IllegalArgumentException - in case of invalid identifier.

    • getPrefixFromTrieIndex

      private static MeasureUnit.MeasurePrefix getPrefixFromTrieIndex(int trieIndex)

    • getTrieIndexForPrefix

      private static int getTrieIndexForPrefix(MeasureUnit.MeasurePrefix prefix)

    • parse

      private MeasureUnitImpl parse()

    • nextSingleUnit

      private SingleUnitImpl nextSingleUnit()
      Returns the next "single unit" via result.

      If a "-per-" was parsed, the result will have appropriate negative dimensionality.

      Throws:
      IllegalArgumentException - if we parse both compound units and "-and-", since mixed compound units are not yet supported - TODO(CLDR-13701).

    • hasNext

      private boolean hasNext()
