      Base collation data, or null if this data itself is a base.

    • nfcImpl

      public Normalizer2Impl nfcImpl

    • compressibleBytes

      public boolean[] compressibleBytes
      256 flags for which primary-weight lead bytes are compressible.

    • fastLatinTable

      public char[] fastLatinTable
      Fast Latin table for common-Latin-text string comparisons. Data structure see class CollationFastLatin.

    • rootElements

      public long[] rootElements
      Collation elements in the root collator. Used by the CollationRootElements class. The data structure is described there. null in a tailoring.

  • Method Details

    • getCE32

      public int getCE32(int c)

    • isUnsafeBackward

      public boolean isUnsafeBackward(int c, boolean numeric)

    • isCompressibleLeadByte

      public boolean isCompressibleLeadByte(int b)

    • isCompressiblePrimary

    • getLastPrimaryForGroup

      public long getLastPrimaryForGroup(int script)
      Returns the last primary for the script's reordering group.
      Returns:
      the last primary of the group (not an actual root collator primary weight), or 0 if the script is unknown
