[jira] [Created] (FLINK-3002) Add an EitherType to the Java API

Stephan Ewen created FLINK-3002:
-----------------------------------

             Summary: Add an EitherType to the Java API
                 Key: FLINK-3002
                 URL: https://issues.apache.org/jira/browse/FLINK-3002
             Project: Flink
          Issue Type: New Feature
          Components: Java API
    Affects Versions: 0.10
            Reporter: Stephan Ewen
             Fix For: 1.0


Either types are recurring patterns and should be serialized efficiently, so it makes sense to add them to the core Java API.

Since Java does not have such a type as of Java 8, we would need to add our own version.

The Scala API handles the Scala Either Type already efficiently. I would not use the Scala Either Type in the Java API, since we are trying to get the {{flink-java}} project "Scala free" for people that don't use Scala and o not want to worry about Scala version matches and mismatches.
