SequencedSet
interface SequencedSet<E : Any!> : SequencedCollection<E>, MutableSet<E>
java.util.SequencedSet |
A collection that is both a SequencedCollection
and a Set
. As such, it can be thought of either as a Set
that also has a well-defined encounter order, or as a SequencedCollection
that also has unique elements.
This interface has the same requirements on the equals
and hashCode
methods as defined by java.util.Set#equals and java.util.Set#hashCode. Thus, a Set
and a SequencedSet
will compare equals if and only if they have equal elements, irrespective of ordering.
SequencedSet
defines the reversed
method, which provides a reverse-ordered view of this set. The only difference from the SequencedCollection.reversed
method is that the return type of SequencedSet.reversed
is SequencedSet
.
This class is a member of the Java Collections Framework.

reversed
abstract fun reversed(): SequencedSet<E>!
Returns a reverse-ordered view of this collection. The encounter order of elements in the returned view is the inverse of the encounter order of elements in this collection. The reverse ordering affects all order-sensitive operations, including those on the view collections of the returned view. If the collection implementation permits modifications to this view, the modifications "write through" to the underlying collection. Changes to the underlying collection might or might not be visible in this reversed view, depending upon the implementation.
