    • readData

      private final void readData(ByteBuffer bytes) throws IOException
      Throws:
      IOException

    • addPropertyStarts

      public final void addPropertyStarts(UnicodeSet set)

    • getExceptionsOffset

      private static final int getExceptionsOffset(int props)

    • propsHasException

      static final boolean propsHasException(int props)

    • hasSlot

      private static final boolean hasSlot(int flags, int index)

    • slotOffset

      private static final byte slotOffset(int flags, int index)

    • getSlotValueAndOffset

      private final long getSlotValueAndOffset(int excWord, int index, int excOffset)
      Get the value of an optional-value slot where hasSlot(excWord, index).
      Parameters:
      excWord - (in) initial exceptions word
      index - (in) desired slot index
      excOffset - (in) offset into exceptions[] after excWord=exceptions.charAt(excOffset++);
      Returns:
      bits 31..0: slot value 63..32: modified excOffset, moved to the last char of the value, use +1 for beginning of next slot

    • getSlotValue

      private final int getSlotValue(int excWord, int index, int excOffset)

    • tolower

      public final int tolower(int c)

    • toupper

      public final int toupper(int c)

    • totitle

      public final int totitle(int c)

    • addCaseClosure

      public final void addCaseClosure(int c, UnicodeSet set)
      Adds all simple case mappings and the full case folding for c to sa, and also adds special case closure mappings. c itself is not added. For example, the mappings - for s include long s - for sharp s include ss - for k include the Kelvin sign

    • addSimpleCaseClosure

      public final void addSimpleCaseClosure(int c, UnicodeSet set)

    • strcmpMax

      private final int strcmpMax(String s, int unfoldOffset, int max)

    • addStringCaseClosure

      public final boolean addStringCaseClosure(String s, UnicodeSet set)
      Maps the string to single code points and adds the associated case closure mappings. The string is mapped to code points if it is their full case folding string. In other words, this performs a reverse full case folding and then adds the case closure items of the resulting code points. If the string is found and its closure applied, then the string itself is added as well as part of its code points' closure.
      Returns:
      true if the string was found

    • getType

      public final int getType(int c)
      Returns:
      NONE, LOWER, UPPER, TITLE

    • getTypeOrIgnorable

      public final int getTypeOrIgnorable(int c)
      Returns:
      like getType() but also sets IGNORABLE if c is case-ignorable

    • getDotType

      public final int getDotType(int c)
      Returns:
      NO_DOT, SOFT_DOTTED, ABOVE, OTHER_ACCENT

    • isSoftDotted

      public final boolean isSoftDotted(int c)

    • isCaseSensitive

    • toFullLower

      public final int toFullLower(int c, UCaseProps.ContextIterator iter, Appendable out, int caseLocale)
      Get the full lowercase mapping for c.
      Parameters:
      c - Character to be mapped.
      iter - Character iterator, used for context-sensitive mappings. See ContextIterator for details. If iter==null then a context-independent result is returned.
      out - If the mapping result is a string, then it is appended to out.
      caseLocale - Case locale value from ucase_getCaseLocale().
      Returns:
      Output code point or string length, see MAX_STRING_LENGTH.
