A non-empty list: an ordered, immutable, non-empty collection of elements with LinearSeq
performance characteristics.
The purpose of NonEmptyVector
is to allow you to express in a type that a Vector
is non-empty, thereby eliminating the need for (and potential exception from) a run-time check for non-emptiness. For a non-empty sequence with IndexedSeq
performance, see Every
.
== Constructing NonEmptyVector
s ==
You can construct a NonEmptyVector
by passing one or more elements to the NonEmptyVector.apply
factory method:
scala> NonEmptyVector(1, 2, 3) res0: org.scalactic.anyvals.NonEmptyVector[Int] = NonEmptyVector(1, 2, 3)
Alternatively you can cons elements onto the End
singleton object, similar to making a Vector
starting with Nil
:
scala> 1 :: 2 :: 3 :: Nil res0: Vector[Int] = Vector(1, 2, 3) scala> 1 :: 2 :: 3 :: End res1: org.scalactic.NonEmptyVector[Int] = NonEmptyVector(1, 2, 3)
Note that although Nil
is a Vector[Nothing]
, End
is not a NonEmptyVector[Nothing]
, because no empty NonEmptyVector
exists. (A non-empty list is a series of connected links; if you have no links, you have no non-empty list.)
scala> val nil: Vector[Nothing] = Nil nil: Vector[Nothing] = Vector() scala> val nada: NonEmptyVector[Nothing] = End <console>:16: error: type mismatch; found : org.scalactic.anyvals.End.type required: org.scalactic.anyvals.NonEmptyVector[Nothing] val nada: NonEmptyVector[Nothing] = End ^
== Working with NonEmptyVector
s ==
NonEmptyVector
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> Vector(1).tail res6: Vector[Int] = Vector()
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, NonEmptyVector
defines a method corresponding to every such Seq
method. Here are some examples:
NonEmptyVector(1, 2, 3).map(_ + 1) // Result: NonEmptyVector(2, 3, 4) NonEmptyVector(1).map(_ + 1) // Result: NonEmptyVector(2) NonEmptyVector(1, 2, 3).containsSlice(NonEmptyVector(2, 3)) // Result: true NonEmptyVector(1, 2, 3).containsSlice(NonEmptyVector(3, 4)) // Result: false NonEmptyVector(-1, -2, 3, 4, 5).minBy(_.abs) // Result: -1
NonEmptyVector
does not currently define any methods corresponding to Seq
methods that could result in an empty Seq
. However, an implicit converison from NonEmptyVector
to Vector
is defined in the NonEmptyVector
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 NonEmptyVector
, even though filter
could result in an empty sequence—but the result type will be Vector
instead of NonEmptyVector
:
NonEmptyVector(1, 2, 3).filter(_ < 10) // Result: Vector(1, 2, 3) NonEmptyVector(1, 2, 3).filter(_ > 10) // Result: Vector()
You can use NonEmptyVector
s in for
expressions. The result will be an NonEmptyVector
unless you use a filter (an if
clause). Because filters are desugared to invocations of filter
, the result type will switch to a Vector
at that point. Here are some examples:
scala> import org.scalactic.anyvals._ import org.scalactic.anyvals._ scala> for (i <- NonEmptyVector(1, 2, 3)) yield i + 1 res0: org.scalactic.anyvals.NonEmptyVector[Int] = NonEmptyVector(2, 3, 4) scala> for (i <- NonEmptyVector(1, 2, 3) if i < 10) yield i + 1 res1: Vector[Int] = Vector(2, 3, 4) scala> for { | i <- NonEmptyVector(1, 2, 3) | j <- NonEmptyVector('a', 'b', 'c') | } yield (i, j) res3: org.scalactic.anyvals.NonEmptyVector[(Int, Char)] = NonEmptyVector((1,a), (1,b), (1,c), (2,a), (2,b), (2,c), (3,a), (3,b), (3,c)) scala> for { | i <- NonEmptyVector(1, 2, 3) if i < 10 | j <- NonEmptyVector('a', 'b', 'c') | } yield (i, j) res6: Vector[(Int, Char)] = Vector((1,a), (1,b), (1,c), (2,a), (2,b), (2,c), (3,a), (3,b), (3,c))
