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])] }

    Deprecated

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
