Value Members

  1. def apply[T](firstElement: T, otherElements: T*)(implicit classTag: ClassTag[T]): NonEmptyArray[T]

    Constructs a new NonEmptyArray given at least one element.

    Constructs a new NonEmptyArray given at least one element.

    T

    the type of the element contained in the new NonEmptyArray

    firstElement

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

    otherElements

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

  2. def from[T](seq: GenSeq[T])(implicit classTag: ClassTag[T]): Option[NonEmptyArray[T]]

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

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

    seq

    the GenSeq with which to construct a NonEmptyArray

    returns

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

  3. implicit def nonEmptyArrayToArray[E](nonEmptyArray: NonEmptyArray[E]): Array[E]

    Implicit conversion from NonEmptyArray to Array.

    Implicit conversion from NonEmptyArray to Array.

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

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

    nonEmptyArray

    the NonEmptyArray to convert to a Array

    returns

    a Array containing the elements, in order, of this NonEmptyArray

  4. implicit def nonEmptyArrayToIterable[E](nonEmptyArray: NonEmptyArray[E]): Iterable[E]
  5. implicit def nonEmptyArrayToPartialFunction[E](nonEmptyArray: NonEmptyArray[E]): PartialFunction[Int, E]
  6. def unapplySeq[T](nonEmptyArray: NonEmptyArray[T]): Option[Seq[T]]

    Variable argument extractor for NonEmptyArrays.

    Variable argument extractor for NonEmptyArrays.

    returns

    an Seq containing this NonEmptyArrays elements, wrapped in a Some
