Subject [jira] Created: (LANG-622) StringUtils.lastIndexOfAnyBut() function desired
Date Wed, 05 May 2010 13:47:04 GMT
StringUtils.lastIndexOfAnyBut() function desired
------------------------------------------------

                 Key: LANG-622
                 URL: https://issues.apache.org/jira/browse/LANG-622
             Project: Commons Lang
          Issue Type: Improvement
            Reporter: david cogen
            Priority: Minor


class StringUtils needs the function lastIndexOfAnyBut()
This would be like indexOfAnyBut() except searches from the end rather than the beginning.
It would be like lastIndexOfAny() except looks for a character other than those in the string
rather than for those in the string.

This is the only one of the four combinations of "from beginning"/"from end" and "for any"/"for
any but" that is not provided.

Interestingly, the class header doc. mentions "LastIndexOfAnyBut" but the function does not
exist - even as a private, as determined by class introspection.

(This is not a frivolous request. I actually did need this function and ended up having to
code a search loop.)
