ASF GitHub Bot commented on FLINK-1159: --------------------------------------- Github user stefanobaghino commented on the pull request: https://github.com/apache/flink/pull/1704#issuecomment-204334976 Note on the tests of the streaming extensions: I couldn't find a more specific class than `SingleOutputStreamOperator[_]`, thus assertion may not be very meaningful. However, I'd leave them in place to make sure further work on the extension won't break them at compile time. > Case style anonymous functions not supported by Scala API > --------------------------------------------------------- > > Key: FLINK-1159 > URL: https://issues.apache.org/jira/browse/FLINK-1159 > Project: Flink > Issue Type: Bug > Components: Scala API > Reporter: Till Rohrmann > Assignee: Stefano Baghino > > In Scala it is very common to define anonymous functions of the following form > {code} > { > case foo: Bar => foobar(foo) > case _ => throw new RuntimeException() > } > {code} > These case style anonymous functions are not supported yet by the Scala API. > Thus, one has to write redundant code to name the function parameter. > What works is the following pattern, but it is not intuitive for someone > coming from Scala: > {code} > dataset.map{ > _ match{ > case foo:Bar => ... > } > } > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
