PatternTypers

trait PatternTypers extends AnyRef

A pattern match such as

x match { case Foo(a, b) => ...}

Might match an instance of any of the following definitions of Foo. Note the analogous treatment between case classes and unapplies.

case class Foo(xs: Int*) case class Foo(a: Int, xs: Int*) case class Foo(a: Int, b: Int) case class Foo(a: Int, b: Int, xs: Int*)

object Foo { def unapplySeq(x: Any): Option[Seq[Int]] } object Foo { def unapplySeq(x: Any): Option[(Int, Seq[Int])] } object Foo { def unapply(x: Any): Option[(Int, Int)] } object Foo { def unapplySeq(x: Any): Option[(Int, Int, Seq[Int])] }
