[jira] [Created] (LANG-1177) Improve indexOf performance when called multiple times

Sebb created LANG-1177:
--------------------------

             Summary: Improve indexOf performance when called multiple times
                 Key: LANG-1177
                 URL: https://issues.apache.org/jira/browse/LANG-1177
             Project: Commons Lang
          Issue Type: Improvement
            Reporter: Sebb


The indexOf methods search for a single entry in an array.
This works fine when only the first matching entry is needed, however it is not so efficient when all matches are needed because of the setup overheads.

It might be useful to introduce an indexesOf method that returns a BitSet containing all the matches.
This can then be used in the removeAllOccurrences methods.
