[jira] [Commented] (IGNITE-1501) Add compare-and-set operation which returns currnet value in case of failure.

    [ https://issues.apache.org/jira/browse/IGNITE-1501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14802951#comment-14802951 ] 

Vladimir Ozerov commented on IGNITE-1501:
-----------------------------------------

At the very least, this includes IgniteAtomicLong and IgniteAtomicReferences classes. 
May be we can also add it to IgniteAtomicStamped, but what to return in this case? IgniteBiTuple?

> Currently our distributed atomics can only return boolean flag in case of failed CAS. We need to extend this and add another method returning previous value.
