[jira] [Resolved] (GROOVY-8223) Multiple Return Values
@CompileStatic Tuple#<> working
[ https://issues.apache.org/jira/browse/GROOVY-8223?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eric Milles resolved GROOVY-8223.
---------------------------------
Fix Version/s: 2.5.x
2.4.x
Resolution: Fixed
Tested with this code:
{code:groovy}
@groovy.transform.CompileStatic
static Tuple2<String,Integer> dostuff() {
new Tuple2<>("answer",42)
}
def (String mystr, Integer myint) = dostuff()
println mystr
println myint
{code}
Prints "answer\n42\n".

> @COmpileStatic seems to bomb with 2.4 if I have:
> 1) a static util function such as:
> class blah {
> static Tuple2<String,Integer> dostuff() { new Tuple2<>("string",55) }
> }
> 2) invoke via:
> def (String mystr, Integer myint) = dostuff()
> With @CompileStatic, that all bombs.
> Alternatively, tried using getAt overrides, also did not work, but that would lack typing infor necessary for @CompileStatic. But the Tuple2 should have the necessary type info...
> I would think this could be done... I might try to do it, but I'd like to file the issue
