> Make WrappingFunction an interface and move to flink-core
> ---------------------------------------------------------
>
> Key: FLINK-5740
> URL: https://issues.apache.org/jira/browse/FLINK-5740
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Aljoscha Krettek
> Priority: Minor
> Labels: auto-deprioritized-major, auto-unassigned
>
> Making it an interface and having an {{AbstractWrappingFunction}} will allow
> implementations to have different classes as base classes. Also, we should
> change {{FunctionUtils}} to work like {{StreamingFunctionUtils}} so that
> wrapping functions don't have to implement the methods of {{RichFunction}}.
> These tests are disabled for now because we cannot properly implement the
> required features:
> - WindowFoldITCase.testFoldWithProcessWindowFunction() (Scala)
> - WindowFunctionITCase.testRichProcessWindowFunction() (Scala)
> - WindowReduceITCase.testReduceWithProcessWindowFunction (Scala)
> Because of the ignored tests I'm updating to "blocker".
