    • UCOL_RUNTIME_VERSION

      public static final VersionInfo UCOL_RUNTIME_VERSION
      Collation runtime version (sort key generator, string comparisons). If the version is different, sort keys for the same string could be different. This value may change in subsequent releases of ICU.

    • UCOL_BUILDER_VERSION

      public static final VersionInfo UCOL_BUILDER_VERSION
      Collation builder code version. When this is different, the same tailoring might result in assigning different collation elements to code points. This value may change in subsequent releases of ICU.

      @Deprecated public static final VersionInfo UCOL_TAILORINGS_VERSION
      Deprecated.
      ICU 54

    • UNICODE_VERSION

      private static final VersionInfo UNICODE_VERSION
      Unicode data version used by the current release. Defined here privately for printing by the main() method in this class. Should be the same as UCharacter.getUnicodeVersion() which gets the version number from a data file. We do not want VersionInfo to have an import dependency on UCharacter.

    • m_version_

      private int m_version_
      Version number stored as a byte for each of the major, minor, milli and micro numbers in the 32 bit int. Most significant for the major and the least significant contains the micro numbers.
