From 4bdad3c21a1461bed6e91ef69dd767fa5211f60d Mon Sep 17 00:00:00 2001 From: Martin Odersky Date: Tue, 14 Feb 2017 09:45:44 +0100 Subject: Change return type of `apply`. In an enum case like case C() extends P1 with ... with Pn ... apply now returns `P1 & ... & Pn`, where before it was just P1. Also, add to Option test. --- tests/run/enum-Option.scala | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'tests') diff --git a/tests/run/enum-Option.scala b/tests/run/enum-Option.scala index 74e449daf..b9efadf0d 100644 --- a/tests/run/enum-Option.scala +++ b/tests/run/enum-Option.scala @@ -2,6 +2,7 @@ enum class Option[+T] extends Serializable { def isDefined: Boolean } object Option { + def apply[T](x: T): Option[T] = if (x == null) None else Some(x) case Some(x: T) { def isDefined = true } @@ -11,6 +12,8 @@ object Option { } object Test { - def main(args: Array[String]) = + def main(args: Array[String]) = { assert(Some(None).isDefined) + Option(22) match { case Option.Some(x) => assert(x == 22) } + } } -- cgit v1.2.3
