      public static final String ICU_BASE_NAME
      The base name of ICU data to be used with ClassLoader.getResourceAsStream(), ICUResourceBundle.getBundleInstance() etc.
      See Also:

    • ICU_COLLATION_BASE_NAME

      public static final String ICU_COLLATION_BASE_NAME
      The base name of collation data to be used with getBundleInstance API

      public static final String ICU_BRKITR_NAME
      The base name of rbbi data to be used with getData API
      See Also:

    • ICU_BRKITR_BASE_NAME

      public static final String ICU_BRKITR_BASE_NAME
      The base name of rbbi data to be used with getBundleInstance API
      See Also:

    • ICU_RBNF_BASE_NAME

      public static final String ICU_RBNF_BASE_NAME
      The base name of rbnf data to be used with getBundleInstance API

    • ICU_TRANSLIT_BASE_NAME

      public static final String ICU_TRANSLIT_BASE_NAME
      The base name of transliterator data to be used with getBundleInstance API
      See Also:

    • ICU_LANG_BASE_NAME

      public static final String ICU_LANG_BASE_NAME
      See Also:

    • ICU_CURR_BASE_NAME

      public static final String ICU_CURR_BASE_NAME
      See Also:

    • ICU_REGION_BASE_NAME

      public static final String ICU_REGION_BASE_NAME
      See Also:

    • ICU_ZONE_BASE_NAME

      public static final String ICU_ZONE_BASE_NAME
      See Also:

    • ICU_UNIT_BASE_NAME

      public static final String ICU_UNIT_BASE_NAME
      See Also:

    • logBinaryDataFromInputStream

      private static final boolean logBinaryDataFromInputStream
      For testing (otherwise false): When reading an InputStream from a Class or ClassLoader (that is, not from a file), log when the stream contains ICU binary data. This cannot be ICUConfig'ured because ICUConfig calls ICUData.getStream() to read the properties file, so we would get a circular dependency in the class initialization.
