NonEmptyString

final class NonEmptyString extends AnyVal

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

The purpose of NonEmptyString is to allow you to express in a type that a String 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 NonEmptyStrings ==

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

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

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

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

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

Note that although Nil is a String[Nothing], End is not a NonEmptyString[Nothing], because no empty NonEmptyString 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: String[Nothing] = Nil
nil: String[Nothing] = String()

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

== Working with NonEmptyStrings ==

NonEmptyString 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> String(1).tail
res6: String[Int] = String()

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

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

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

NonEmptyString(1, 2, 3).filter(_ < 10) // Result: String(1, 2, 3)
NonEmptyString(1, 2, 3).filter(_ > 10) // Result: String()

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

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

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

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

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

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

Value parameters:
c

final def zipAll[O](other: Iterable[O], thisElem: Char, otherElem: O): Iterable[(Char, O)]

Returns a NonEmptyString formed from this NonEmptyString 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 NonEmptyString formed from this NonEmptyString 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.

Type parameters:
O

the element type of the other

Value parameters:
other

the Iterable providing the second half of each result pair

otherElem

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

thisElem

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

Returns:

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