-----------------------------------
Labels: stale-assigned (was: )
> Further relax the UDF constraints for Java classes
> --------------------------------------------------
>
> Key: FLINK-15600
> URL: https://issues.apache.org/jira/browse/FLINK-15600
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Reporter: Timo Walther
> Assignee: Timo Walther
> Priority: Major
> Labels: stale-assigned
>
> FLINK-12283 already relaxed the UDF constraints for classes which is a big
> usability improvement for Scala users. However, Java users are still facing
> issues when using anonymous inner classes.
> We should allow the following:
> {code}
> tEnv.registerFunction("testi", new ScalarFunction() {
> public String eval(Integer i) {
> return String.valueOf(i);
> }
> });
> {code}
