org.scalactic

End

object End

Object that can be used as an endpoint for Chain construction expressions that use the cons (::) operator.

Here's an example:

scala> 1 :: 2 :: 3 :: End
res0: org.scalactic.Chain[Int] = Chain(1, 2, 3)

Note that unlike Nil, which is an instance of List[Nothing], End is not an instance of Chain[Nothing], because there is no empty Chain:

scala> Nil.isInstanceOf[List[_]]
res0: Boolean = true
scala> End.isInstanceOf[Chain[_]]
res1: Boolean = false

  4. def ::[T](element: T): Chain[T]

    A :: operator that serves to start a Chain construction expression.

    A :: operator that serves to start a Chain construction expression.

    The result of calling this method will always be a Chain of length 1. Here's an example:

    scala> 1 :: End
res0: org.scalactic.Chain[Int] = Chain(1)
