See theNonEmptyArray companion object
final class NonEmptyArray[T] extends AnyVal

A non-empty array: an ordered, mutable, non-empty collection of elements with IndexedSeq performance characteristics.

The purpose of NonEmptyArray is to allow you to express in a type that an Array is non-empty, thereby eliminating the need for (and potential exception from) a run-time check for non-emptiness. For a non-empty immutable sequence with IndexedSeq performance, see Every.

== Constructing NonEmptyArrays ==

You can construct a NonEmptyArray by passing one or more elements to the NonEmptyArray.apply factory method:

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

== Working with NonEmptyArrays ==

NonEmptyArray does not extend Scala's Seq or Traversable traits because these require that implementations may be empty. For example, if you invoke tail on a Seq that contains just one element, you'll get an empty Seq:

scala> Array(1).tail
res6: Array[Int] = Array()

On the other hand, many useful methods exist on Seq that when invoked on a non-empty Seq are guaranteed to not result in an empty Seq. For convenience, NonEmptyArray defines a method corresponding to every such Seq method. Here are some examples:

NonEmptyArray(1, 2, 3).map(_ + 1)                        // Result: NonEmptyArray(2, 3, 4)
NonEmptyArray(1).map(_ + 1)                              // Result: NonEmptyArray(2)
NonEmptyArray(1, 2, 3).containsSlice(NonEmptyArray(2, 3)) // Result: true
NonEmptyArray(1, 2, 3).containsSlice(NonEmptyArray(3, 4)) // Result: false
NonEmptyArray(-1, -2, 3, 4, 5).minBy(_.abs)              // Result: -1

NonEmptyArray does not currently define any methods corresponding to Seq methods that could result in an empty Seq. However, an implicit converison from NonEmptyArray to Array is defined in the NonEmptyArray companion object that will be applied if you attempt to call one of the missing methods. As a result, you can invoke filter on an NonEmptyArray, even though filter could result in an empty sequence—but the result type will be Array instead of NonEmptyArray:

NonEmptyArray(1, 2, 3).filter(_ < 10) // Result: Array(1, 2, 3)
NonEmptyArray(1, 2, 3).filter(_ > 10) // Result: Array()

You can use NonEmptyArrays in for expressions. The result will be an NonEmptyArray unless you use a filter (an if clause). Because filters are desugared to invocations of filter, the result type will switch to a Array at that point. Here are some examples:

scala> import org.scalactic.anyvals._
import org.scalactic.anyvals._

scala> for (i <- NonEmptyArray(1, 2, 3)) yield i + 1
res0: org.scalactic.anyvals.NonEmptyArray[Int] = NonEmptyArray(2, 3, 4)

scala> for (i <- NonEmptyArray(1, 2, 3) if i < 10) yield i + 1
res1: Array[Int] = Array(2, 3, 4)

scala> for {
    |   i <- NonEmptyArray(1, 2, 3)
    |   j <- NonEmptyArray('a', 'b', 'c')
    | } yield (i, j)
res3: org.scalactic.anyvals.NonEmptyArray[(Int, Char)] =
       NonEmptyArray((1,a), (1,b), (1,c), (2,a), (2,b), (2,c), (3,a), (3,b), (3,c))

scala> for {
    |   i <- NonEmptyArray(1, 2, 3) if i < 10
    |   j <- NonEmptyArray('a', 'b', 'c')
    | } yield (i, j)
res6: Array[(Int, Char)] =
       Array((1,a), (1,b), (1,c), (2,a), (2,b), (2,c), (3,a), (3,b), (3,c))

This method is unavailable unless the elements are members of Tuple2, each ((K, V)) becoming a key-value pair in the map. Duplicate keys will be overwritten by later keys.

Attributes

Returns

a map of type immutable.Map[K, V] containing all key/value pairs of type (K, V) of this NonEmptyArray.

A copy of this NonEmptyArray with one single replaced element.

Value parameters

elem

the replacing element

idx

final def zipAll[O, U >: T](other: Iterable[O], thisElem: U, otherElem: O): NonEmptyArray[(U, O)]

Returns a NonEmptyArray formed from this NonEmptyArray and an iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements will be used to extend the shorter collection to the length of the longer.

Returns a NonEmptyArray formed from this NonEmptyArray and an iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements will be used to extend the shorter collection to the length of the longer.

Value parameters

other

the Iterable providing the second half of each result pair

thatElem

the element to be used to fill up the result if that Iterable is shorter than this NonEmptyArray.

thisElem

the element to be used to fill up the result if this NonEmptyArray is shorter than that Iterable.

Attributes

Returns

a new NonEmptyArray containing pairs consisting of corresponding elements of this NonEmptyArray and that. The length of the returned collection is the maximum of the lengths of this NonEmptyArray and that. If this NonEmptyArray is shorter than that, thisElem values are used to pad the result. If that is shorter than this NonEmptyArray, thatElem values are used to pad the result.
