["Vladimir Sitnikov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPTIQ-314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14046734#comment-14046734 ] 

Vladimir Sitnikov commented on OPTIQ-314:
-----------------------------------------

Are you sure it is not available now?

[public static ScalarFunction ScalarFunctionImpl.create(Method method)|https://github.com/julianhyde/optiq/blob/master/core/src/main/java/net/hydromatic/optiq/impl/ScalarFunctionImpl.java#L68] should do the trick.

> We already allow UDFs based on classes, provided that that classes have just one method. This change would allow UDFs based on classes with several methods.
> E.g. should be able to use 'String String.replace(String s, String s2)' as a SQL UDF 'REPLACE(String, String, String) RETURNS String'.
