Stefan Richter commented on FLINK-5740: --------------------------------------- +1 very good idea. > 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}}. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
