Produces a new Every that contains all elements of this Every and also all elements of a given GenSeq.
Produces a new Every that contains all elements of this Every and also all elements of a given GenSeq.
everyX union ys is equivalent to everyX ++ ys.
Another way to express this is that everyX union ys computes the order-presevring multi-set union
of everyX and ys. This union method is hence a counter-part of diff and intersect that
also work on multi-sets.

everyX union everyY is equivalent to everyX ++ everyY.
Another way to express this is that everyX union everyY computes the order-presevring multi-set union
of everyX and everyY. This union method is hence a counter-part of diff and intersect that
also work on multi-sets.

Returns an Every formed from this Every and an iterable collection by combining corresponding
elements in pairs.
Returns an Every formed from this Every 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.
the Iterable providing the second half of each result pair
the element to be used to fill up the result if this Every is shorter than that Iterable.
a new Every containing pairs consisting of corresponding elements of this Every and that. The
length of the returned collection is the maximum of the lengths of this Every and that. If this Every
is shorter than that, thisElem values are used to pad the result. If that is shorter than this
Every, thatElem values are used to pad the result.

An ordered, immutable, non-empty collection of elements.
Class
Everyhas two and only two subtypes:OneandMany. AOnecontains exactly one element. AManycontains two or more elements. Thus no way exists for anEveryto contain zero elements.Constructing
EverysYou can construct an
Everyby passing one or more elements to theEvery.applyfactory method:Alternatively you can pass one element to the
One.applyfactory method, or two or more elements toMany.apply:Working with
EverysEverydoes 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,Everydefines a method corresponding to every suchSeqmethod. Here are some examples:Everydoes not currently define any methods corresponding toSeqmethods that could result in an emptySeq. However, an implicit converison fromEverytocollection.immutable.IndexedSeqis defined in theEverycompanion object that will be applied if you attempt to call one of the missing methods. As a result, you can invokefilteron anEvery, even thoughfiltercould result in an empty sequence—but the result type will becollection.immutable.IndexedSeqinstead ofEvery:You can use
Everys inforexpressions. The result will be anEveryunless you use a filter (anifclause). Because filters are desugared to invocations offilter, the result type will switch to acollection.immutable.IndexedSeqat that point. Here are some examples:scala> import org.scalactic._ import org.scalactic._ scala> for (i <- Every(1, 2, 3)) yield i + 1 res0: org.scalactic.Every[Int] = Many(2, 3, 4) scala> for (i <- Every(1, 2, 3) if i < 10) yield i + 1 res1: scala.collection.immutable.IndexedSeq[Int] = Vector(2, 3, 4) scala> for { | i <- Every(1, 2, 3) | j <- Every('a', 'b', 'c') | } yield (i, j) res3: org.scalactic.Every[(Int, Char)] = Many((1,a), (1,b), (1,c), (2,a), (2,b), (2,c), (3,a), (3,b), (3,c)) scala> for { | i <- Every(1, 2, 3) if i < 10 | j <- Every('a', 'b', 'c') | } yield (i, j) res6: scala.collection.immutable.IndexedSeq[(Int, Char)] = Vector((1,a), (1,b), (1,c), (2,a), (2,b), (2,c), (3,a), (3,b), (3,c))Motivation for
EverysAlthough
Everyis a general-purpose, non-empty ordered collection, it was motivated by the desire to enable easy accumulation of errors inOrs. For examples ofEveryused in that use case, see the Accumulating errors withOrsection in the main documentation forOr.the type of elements contained in this
