Subject [jira] [Commented] (FLINK-2023) TypeExtractor does not work for (some) Scala Classes
Date Sat, 16 May 2015 22:51:59 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2023?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14546970#comment-14546970

Alexander Alexandrov commented on FLINK-2023:

Long story short - you cannot use the Java API directly from Scala (i.e., with Scala types)
and rely on correct type inference form the TypeExtractor.

> [~vanaepi] discovered some problems while working on the Scala Gelly API where, for example,
a Scala MapFunction can not be correctly analyzed by the type extractor. For example, generic
types will not be correctly detected.
