object End

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

Here's an example:

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

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

scala> Nil.isInstanceOf[List[_]]
res0: Boolean = true

scala> End.isInstanceOf[NonEmptyList[_]]
res1: Boolean = false

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

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

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

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