    • normalize

      public StringBuilder normalize(CharSequence src, StringBuilder dest)
      Description copied from class: Normalizer2
      Writes the normalized form of the source string to the destination string (replacing its contents) and returns the destination string. The source and destination strings must be different objects.
      Specified by:
      normalize in class Normalizer2
      Parameters:
      src - source string
      dest - destination string; its contents is replaced with normalized src
      Returns:
      dest

    • normalize

      public Appendable normalize(CharSequence src, Appendable dest)
      Description copied from class: Normalizer2
      Writes the normalized form of the source string to the destination Appendable and returns the destination Appendable. The source and destination strings must be different objects.

      Any IOException is wrapped into a ICUUncheckedIOException.

      Specified by:
      normalize in class Normalizer2
      Parameters:
      src - source string
      dest - destination Appendable; gets normalized src appended
      Returns:
      dest

    • normalize

      protected abstract void normalize(CharSequence src, Normalizer2Impl.ReorderingBuffer buffer)

    • normalizeSecondAndAppend

      public StringBuilder normalizeSecondAndAppend(StringBuilder first, CharSequence second)
      Description copied from class: Normalizer2
      Appends the normalized form of the second string to the first string (merging them at the boundary) and returns the first string. The result is normalized if the first string was normalized. The first and second strings must be different objects.
      Specified by:
      normalizeSecondAndAppend in class Normalizer2
      Parameters:
      first - string, should be normalized
      second - string, will be normalized
      Returns:
      first

    • append

      public StringBuilder append(StringBuilder first, CharSequence second)
      Description copied from class: Normalizer2
      Appends the second string to the first string (merging them at the boundary) and returns the first string. The result is normalized if both the strings were normalized. The first and second strings must be different objects.
      Specified by:
      append in class Normalizer2
      Parameters:
      first - string, should be normalized
      second - string, should be normalized
      Returns:
      first

    • normalizeSecondAndAppend

      public StringBuilder normalizeSecondAndAppend(StringBuilder first, CharSequence second, boolean doNormalize)

    • normalizeAndAppend

      protected abstract void normalizeAndAppend(CharSequence src, boolean doNormalize, Normalizer2Impl.ReorderingBuffer buffer)

    • getDecomposition

      public String getDecomposition(int c)
      Description copied from class: Normalizer2
      Gets the decomposition mapping of c. Roughly equivalent to normalizing the String form of c on a DECOMPOSE Normalizer2 instance, but much faster, and except that this function returns null if c does not have a decomposition mapping in this instance's data. This function is independent of the mode of the Normalizer2.
      Specified by:
      getDecomposition in class Normalizer2
      Parameters:
      c - code point
      Returns:
      c's decomposition mapping, if any; otherwise null

    • getRawDecomposition

      public String getRawDecomposition(int c)
      Description copied from class: Normalizer2
      Gets the raw decomposition mapping of c.

      This is similar to the getDecomposition() method but returns the raw decomposition mapping as specified in UnicodeData.txt or (for custom data) in the mapping files processed by the gennorm2 tool. By contrast, getDecomposition() returns the processed, recursively-decomposed version of this mapping.

      When used on a standard NFKC Normalizer2 instance, getRawDecomposition() returns the Unicode Decomposition_Mapping (dm) property.

      When used on a standard NFC Normalizer2 instance, it returns the Decomposition_Mapping only if the Decomposition_Type (dt) is Canonical (Can); in this case, the result contains either one or two code points (=1..4 Java chars).

      This function is independent of the mode of the Normalizer2. The default implementation returns null.

      Overrides:
      getRawDecomposition in class Normalizer2
      Parameters:
      c - code point
      Returns:
      c's raw decomposition mapping, if any; otherwise null

    • composePair

      public int composePair(int a, int b)
      Description copied from class: Normalizer2
      Performs pairwise composition of a & b and returns the composite if there is one.

      Returns a composite code point c only if c has a two-way mapping to a+b. In standard Unicode normalization, this means that c has a canonical decomposition to a+b and c does not have the Full_Composition_Exclusion property.

      This function is independent of the mode of the Normalizer2. The default implementation returns a negative value.

      Overrides:
      composePair in class Normalizer2
      Parameters:
      a - A (normalization starter) code point.
      b - Another code point.
      Returns:
      The non-negative composite code point if there is one; otherwise a negative value.

    • getCombiningClass

      public int getCombiningClass(int c)
      Description copied from class: Normalizer2
      Gets the combining class of c. The default implementation returns 0 but all standard implementations return the Unicode Canonical_Combining_Class value.
      Overrides:
      getCombiningClass in class Normalizer2
      Parameters:
      c - code point
      Returns:
      c's combining class

    • isNormalized

      public boolean isNormalized(CharSequence s)
      Description copied from class: Normalizer2
      Tests if the string is normalized. Internally, in cases where the quickCheck() method would return "maybe" (which is only possible for the two COMPOSE modes) this method resolves to "yes" or "no" to provide a definitive result, at the cost of doing more work in those cases.
      Specified by:
      isNormalized in class Normalizer2
      Parameters:
      s - input string
      Returns:
      true if s is normalized

    • quickCheck

      public Normalizer.QuickCheckResult quickCheck(CharSequence s)
      Description copied from class: Normalizer2
      Tests if the string is normalized. For the two COMPOSE modes, the result could be "maybe" in cases that would take a little more work to resolve definitively. Use spanQuickCheckYes() and normalizeSecondAndAppend() for a faster combination of quick check + normalization, to avoid re-checking the "yes" prefix.
      Specified by:
      quickCheck in class Normalizer2
      Parameters:
      s - input string
      Returns:
      the quick check result
