ASF GitHub Bot commented on FLINK-2806: --------------------------------------- GitHub user ggevay opened a pull request: https://github.com/apache/flink/pull/1212 [FLINK-2806] [scala-api] Add a TypeInformation[Nothing]. I added a TypeInfo[Nothing] class, and added a line to workaround the compiler bug. I also added a test for this, which tests at compile time: if the "implicit val scalaNothingTypeInfo" is not there, then it does not compile.

Two problems prevent me from getting it: > 1. TypeInformationGen.mkTypeInfo doesn't return a real > TypeInformation[Nothing]. (It actually returns a casted null in that case.) > 2. The line > implicit def createTypeInformation[T]: TypeInformation[T] = macro > TypeUtils.createTypeInfo[T] > does not fire in some situations when it should, when T = Nothing. (I guess > this is a compiler bug.) > I will open a PR shortly. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
