trait Emptiness[-T] extends AnyRef

Supertrait for typeclasses that enable be empty matcher syntax.

An Emptiness[T] provides access to the "emptiness" of type T in such a way that be empty matcher syntax can be used with type T. A T can be any type that in some way can be empty. ScalaTest provides implicit implementations for several types. You can enable the be empty matcher syntax on your own type U by defining an Emptiness[U] for the type and making it available implicitly.

ScalaTest provides implicit Emptiness instances for scala.collection.GenTraversable, java.util.Collection, java.util.Map, String, Array, and scala.Option in the Emptiness companion object.
