  4. def apply[T](firstElement: T, otherElements: T*): NonEmptyList[T]

    Constructs a new NonEmptyList given at least one element.

    Constructs a new NonEmptyList given at least one element.

    T

    the type of the element contained in the new NonEmptyList

    firstElement

    the first element (with index 0) contained in this NonEmptyList

    otherElements

    a varargs of zero or more other elements (with index 1, 2, 3, ...) contained in this NonEmptyList

  9. def from[T](seq: GenSeq[T]): Option[NonEmptyList[T]]

    Optionally construct a NonEmptyList containing the elements, if any, of a given GenSeq.

    Optionally construct a NonEmptyList containing the elements, if any, of a given GenSeq.

    seq

    the GenSeq with which to construct a NonEmptyList

    returns

    a NonEmptyList containing the elements of the given GenSeq, if non-empty, wrapped in a Some; else None if the GenSeq is empty

  14. implicit def nonEmptyListToList[E](nonEmptyList: NonEmptyList[E]): List[E]

    Implicit conversion from NonEmptyList to List.

    Implicit conversion from NonEmptyList to List.

    One use case for this implicit conversion is to enable GenSeq[NonEmptyList]s to be flattened. Here's an example:

    scala> Vector(NonEmptyList(1, 2, 3), NonEmptyList(3, 4), NonEmptyList(5, 6, 7, 8)).flatten
    res0: scala.collection.immutable.Vector[Int] = Vector(1, 2, 3, 3, 4, 5, 6, 7, 8)
    

    nonEmptyList

    the NonEmptyList to convert to a List

    returns

    a List containing the elements, in order, of this NonEmptyList
