[jira] [Commented] (DERBY-3069) Derby does not resolve functions
bound to methods with varargs.
[ https://issues.apache.org/jira/browse/DERBY-3069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13510743#comment-13510743 ]
Rick Hillegas commented on DERBY-3069:
--------------------------------------
The current rev of the functional spec needs a correction: The spec says that the varargs ... delimiter is only allowed if the parameter style is DERBY. I need to update to say that varargs are also allowed for parameter style DERBY_JDBC_RESULT_SET. Before posting a new spec, I will wait to see if other corrections to the spec arise during implementation.

> Varargs were added in Java 5. It would be nice if Derby let you invoke a function bound to a method with a variable length argument list. The Reference Guide states a small number of restrictions for methods which can be invoked as Derby functions: They must be public, static, and not have arguments which are long datatypes. I see no reason that Derby shouldn't be able to resolve and invoke functions which are bound to methods which don't suffer these limitations but which have variable argument lists.
