  1. implicit def NonEmptySetToSet[E](NonEmptySet: NonEmptySet[E]): Set[E]

    Implicit conversion from NonEmptySet to Set.

    Implicit conversion from NonEmptySet to Set.

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

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

    NonEmptySet

    the NonEmptySet to convert to a Set

    returns

    a Set containing the elements, in order, of this NonEmptySet

  2. def apply[T](firstElement: T, otherElements: T*): NonEmptySet[T]

    Constructs a new NonEmptySet given at least one element.

    Constructs a new NonEmptySet given at least one element.

    T

    the type of the element contained in the new NonEmptySet

    firstElement

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

    otherElements

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

  3. def from[T](set: GenSet[T]): Option[NonEmptySet[T]]

    Optionally construct a NonEmptySet containing the elements, if any, of a given GenSet.

    Optionally construct a NonEmptySet containing the elements, if any, of a given GenSet.

    set

    the GenSet with which to construct a NonEmptySet

    returns

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

  4. def unapplySeq[T](nonEmptySet: NonEmptySet[T]): Option[Seq[T]]

    Variable argument extractor for NonEmptySets.

    Variable argument extractor for NonEmptySets.

    returns

    an Seq containing this NonEmptySets elements, wrapped in a Some
