Jark Wu commented on FLINK-7410:
--------------------------------
How about using the `toString()` method to return the custom display name? This
will avoid to introduce additional default method.
> Add getName method to UserDefinedFunction

> Key: FLINK-7410
> URL: https://issues.apache.org/jira/browse/FLINK-7410
> Project: Flink
> Issue Type: Improvement
> Components: Table API & SQL
> Affects Versions: 1.4.0
> Reporter: Hequn Cheng
> Assignee: Hequn Cheng
>
> *Motivation*
> Operator names setted in table-api are used by visualization and logging, it
> is import to make these names simple and readable. Currently,
> UserDefinedFunction’s name contains class CanonicalName and md5 value making
> the name too long and unfriendly to users.
> As shown in the following example,
> {quote}
> select: (a, b, c,
> org$apache$flink$table$expressions$utils$RichFunc1$281f7e61ec5d8da894f5783e2e17a4f5(a)
> AS _c3,
> org$apache$flink$table$expressions$utils$RichFunc2$fb99077e565685ebc5f48b27edc14d98(c)
> AS _c4)
> {quote}
> *Changes:*
>
> Provide getName method for UserDefinedFunction. The method will return class
> name by default. Users can also override the method to return whatever he
> wants.
> What do you think [~fhueske] ?
