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().

Method Detail

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 extends Collection.

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface ObjectIterable<K>

Returns:

a type-specific iterator on the elements of this collection.
