[jira] [Created] (FLINK-5740) Make WrappingFunction an interface and move to flink-core

Aljoscha Krettek created FLINK-5740:
---------------------------------------

             Summary: 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: Core
            Reporter: Aljoscha Krettek
            Assignee: Aljoscha Krettek


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}}.
