public interface ReferenceCollection<K> extends Collection<K>, ObjectIterable<K>
A type-specific
Collection
; provides some additional methods that use
polymorphism to avoid (un)boxing.
Additionally, this class defines strengthens (again) iterator()

iterator
ObjectIterator<K> iterator()Returns a type-specific iterator on the elements of this collection.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 extendsCollection
