Subject [jira] [Commented] (FLINK-2023) TypeExtractor does not work for (some) Scala Classes
Date Mon, 18 May 2015 09:37:59 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2023?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14547776#comment-14547776

PJ Van Aeken commented on FLINK-2023:
-------------------------------------

Indeed you are right. In the Java API, keyType and valueType are used to construct returnType,
but since I am already constructing it, they serve no purpose. In any case, I will log a ticket
to add these overloaded methods into the Java Gelly API. Thanks!

> [~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.
