[jira] Commented: (LANG-470) Add containsAll methods to ArrayUtils

["Henri Yandell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12798543#action_12798543 ] 

Henri Yandell commented on LANG-470:
------------------------------------

The reason (along with LANG-238) is that reimplementing all of the Set /Collection interface as Array methods is not the best use of ArrayUtils.

Having a way to get to the Set API might be desirable - options would seem to be:

* An asSet method that returns a HashSet using the above (with null protection).
* An asSet method that returns an ArraySet (might be value in this).
* Additionally a null protected asList could be added to handle your NPE comment and would be reused if the HashSet option is chosen.
