Interface ReferenceSet<K>

All Superinterfaces:

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

All Known Subinterfaces:

ReferenceSortedSet<K>

All Known Implementing Classes:

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().

Method Details

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.

iterator in interface Collection<K>
