An ordered, immutable, non-empty collection of elements.
Class
Every
has two and only two subtypes:One
andMany
. AOne
contains exactly one element. AMany
contains two or more elements. Thus no way exists for anEvery
to contain zero elements.Constructing
Every
sYou can construct an
Every
by passing one or more elements to theEvery.apply
factory method:Alternatively you can pass one element to the
One.apply
factory method, or two or more elements toMany.apply
:Working with
Every
sEvery
does not extend Scala'sSeq
orTraversable
traits because these require that implementations may be empty. For example, if you invoketail
on aSeq
that contains just one element, you'll get an emptySeq
:On the other hand, many useful methods exist on
Seq
that when invoked on a non-emptySeq
are guaranteed to not result in an emptySeq
. For convenience,Every
defines a method corresponding to every suchSeq
method. Here are some examples:Every
does not currently define any methods corresponding toSeq
methods that could result in an emptySeq
. However, an implicit converison fromEvery
tocollection.immutable.IndexedSeq
is defined in theEvery
companion object that will be applied if you attempt to call one of the missing methods. As a result, you can invokefilter
on anEvery
, even thoughfilter
could result in an empty sequence—but the result type will becollection.immutable.IndexedSeq
instead ofEvery
:You can use
Every
s infor
expressions. The result will be anEvery
unless you use a filter (anif
clause). Because filters are desugared to invocations offilter
, the result type will switch to acollection.immutable.IndexedSeq
at that point. Here are some examples:Motivation for
Every
sAlthough
Every
is a general-purpose, non-empty ordered collection, it was motivated by the desire to enable easy accumulation of errors inOr
