A non-empty list: an ordered, immutable, non-empty collection of elements with
LinearSeqperformance characteristics.The purpose of
NonEmptyVectoris to allow you to express in a type that aVectoris non-empty, thereby eliminating the need for (and potential exception from) a run-time check for non-emptiness. For a non-empty sequence withIndexedSeqperformance, seeEvery.Constructing
NonEmptyVectorsYou can construct a
NonEmptyVectorby passing one or more elements to theNonEmptyVector.applyfactory method:Alternatively you can cons elements onto the
Endsingleton object, similar to making aVectorstarting withNil:Note that although
Nilis aVector[Nothing],Endis not aNonEmptyVector[Nothing], because no emptyNonEmptyVectorexists. (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
NonEmptyVectorsNonEmptyVectordoes not extend Scala'sSeqorTraversabletraits because these require that implementations may be empty. For example, if you invoketailon aSeqthat contains just one element, you'll get an emptySeq:On the other hand, many useful methods exist on
Seqthat when invoked on a non-emptySeqare guaranteed to not result in an emptySeq. For convenience,NonEmptyVectordefines a method corresponding to every suchSeqmethod. Here are some examples:NonEmptyVectordoes not currently define any methods corresponding toSeqmethods that could result in an emptySeq. However, an implicit converison fromNonEmptyVectortoVectoris defined in theNonEmptyVectorcompanion object that will be applied if you attempt to call one of the missing methods. As a result, you can invokefilteron anNonEmptyVector, even thoughfiltercould result in an empty sequence—but the result type will beVectorinstead ofNonEmptyVector:You can use
NonEmptyVectors inforexpressions. The result will be anNonEmptyVectorunless you use a filter (anifclause). Because filters are desugared to invocations offilter, the result type will switch to aVectorat 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))the type of elements contained in this
