Subject [jira] Commented: (DERBY-3069) Derby does not resolve functions bound to methods with varargs.

Daniel John Debrunner commented on DERBY-3069:
----------------------------------------------

> I do not believe that varargs change the definition of JPDL.
> However, I believe that varargs can add more candidate methods to JCS.
> So I believe it is that delta to JCS which must be described. Again, does that sound
correct to you?

I think this all depends on what you intend to implement (or have implemented). E.g. JPDL
could support a varargs declaration in its <Java parameter declaration list>, not sure
if you intend to do this or not, since it's non standard I can't guess what you are trying
to implement, thus it's hard to review any patch as it's unclear what the intended behave
is, beyond a vague "support varargs" statement.

> 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.
