> Clarify JavaDoc of StringUtils.containsAny()
> --------------------------------------------
>
> Key: LANG-1182
> URL: https://issues.apache.org/jira/browse/LANG-1182
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.*
> Affects Versions: 3.4
> Reporter: Larry West
> Assignee: Benedikt Ritter
> Priority: Minor
> Fix For: 3.5
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> (1) The javadoc for StringUtils.containsAny(CharSequence cs, CharSequence... searchCharSequences) confusingly says
> * StringUtils.containsAny("abcd", "ab", "cd") = false
> You can verify this actually returns true by running this:
> if (!StringUtils.containsAny("abcd", "ab", "cd"))
> throw new AssertionError("Third sample from StringUtils 3.4 javadoc");
> (2) The javadoc for containsAny(final CharSequence cs, final CharSequence searchChars) is inadequate, and could easily mislead naive readers to believe this containsAny() looks for a matching sequence (substring) rather than characters in a set:
> * StringUtils.containsAny("zzabyycdxx", "za") = true
> * StringUtils.containsAny("zzabyycdxx", "by") = true
> In other words, both examples would be equally true for StringUtils.contains(). I suggest adding clarifying examples, like:
> * StringUtils.containsAny("zzabyycdxx", "\tx") = true
> * StringUtils.containsAny("zzabyycdxx", "$.#yF") = true
