final class NESet[T] extends AnyVal

A non-empty Set: an ordered, immutable, non-empty collection of elements with LinearSeq performance characteristics.

The purpose of NESet is to allow you to express in a type that a Set 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 Vector.

Constructing NESets

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

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

Alternatively you can cons elements onto the End singleton object, similar to making a Set starting with Nil:

scala> 1 :: 2 :: 3 :: Nil
res0: Set[Int] = Set(1, 2, 3)

scala> 1 :: 2 :: 3 :: End
res1: org.scalactic.NESet[Int] = NESet(1, 2, 3)

Note that although Nil is a Set[Nothing], End is not a NESet[Nothing], because no empty NESet exists. (A non-empty Set is a series of connected links; if you have no links, you have no non-empty Set.)

scala> val nil: Set[Nothing] = Nil
nil: Set[Nothing] = Set()

scala> val nada: NESet[Nothing] = End
<console>:16: error: type mismatch;
found   : org.scalactic.anyvals.End.type
required: org.scalactic.anyvals.NESet[Nothing]
       val nada: NESet[Nothing] = End
                                         ^

Working with NESets

NESet 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> Set(1).tail
res6: Set[Int] = Set()

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, NESet defines a method corresponding to every such Seq method. Here are some examples:

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

NESet does not currently define any methods corresponding to Seq methods that could result in an empty Seq. However, an implicit converison from NESet to Set is defined in the NESet 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 NESet, even though filter could result in an empty sequence—but the result type will be Set instead of NESet:

NESet(1, 2, 3).filter(_ < 10) // Result: Set(1, 2, 3)
NESet(1, 2, 3).filter(_ > 10) // Result: Set()

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

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

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

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

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

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