Method Detail

### isSet

    public boolean isSet(UnicodeUnescaper.OPTION opt)

### translate

    public int translate(CharSequence input,
                         int index,
                         Writer out)
                  throws IOException

  Translate a set of codepoints, represented by an int index into a CharSequence, into another set of codepoints. The number of codepoints consumed must be returned, and the only IOExceptions thrown must be from interacting with the Writer so that the top level API may reliable ignore StringWriter IOExceptions.

    `translate` in class `CharSequenceTranslator`
  Parameters:
    `input` - CharSequence that is being translated
    `index` - int representing the current point of translation
    `out` - Writer to translate the text to
  Returns:
    int count of codepoints consumed
  Throws:
    `IOException` - if and only if the Writer produces an IOException
