ReferenceSet (fastutil 8.4.4)

All Superinterfaces:

Collection<K>, Iterable<K>, ObjectIterable<K>, ReferenceCollection<K>, Set<K>

All Known Subinterfaces:

ReferenceSortedSet<K>

All Known Implementing Classes:

AbstractReferenceSet, AbstractReferenceSortedSet, ReferenceArraySet, ReferenceLinkedOpenHashSet, ReferenceOpenHashBigSet, ReferenceOpenHashSet, ReferenceSets.EmptySet, ReferenceSets.Singleton, ReferenceSets.SynchronizedSet, ReferenceSets.UnmodifiableSet, ReferenceSortedSets.EmptySet, ReferenceSortedSets.Singleton, ReferenceSortedSets.SynchronizedSortedSet, ReferenceSortedSets.UnmodifiableSortedSet
```
public interface ReferenceSet<K>
extends ReferenceCollection<K>, Set<K>
```
A type-specific Set; provides some additional methods that use polymorphism to avoid (un)boxing.
Additionally, this interface strengthens (again) iterator().

```
ObjectIterator<K> iterator()
```
    Returns a type-specific iterator on the elements of this set.
    Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Set.

@SafeVarargs
static <K> ReferenceSet<K> of(K... a)
```
    Creates a new set using a list of elements.
    
    Parameters:
    
    a - a list of elements that will be used to initialize the new set.
