Subject [jira] [Commented] (REEF-1404) IMRU task state Maintenance and Preservation in Evaluator for fault tolerant
Date Wed, 21 Sep 2016 00:08:20 GMT

    [ https://issues.apache.org/jira/browse/REEF-1404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15508205#comment-15508205

Julia commented on REEF-1404:
-----------------------------

So are you saying to define the interface as below:
    public interface IStateManager1<T1, T2>
    {
        void AddState(T1 stateObject);

        T2 GetLatestState();
    }

In IMRU case, T1 is TMapInput and T2 is TResult?
