## Class OctalUnescaper

- java.lang.Object
- - org.apache.commons.lang3.text.translate.CharSequenceTranslator
  - - org.apache.commons.lang3.text.translate.OctalUnescaper

-     public class OctalUnescaper
      extends CharSequenceTranslator

  Translate escaped octal Strings back to their octal values. For example, "\45" should go back to being the specific value (a %). Note that this currently only supports the viable range of octal for Java; namely 1 to 377. This is because parsing Java is the main use case.

  - ### Method Detail

    - #### 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 reliably ignore StringWriter IOExceptions.
      Specified by:
        `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
