Interface ReferenceSet<K>

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().

Method Detail

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.

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in interface Set<K>

Returns:

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

remove

boolean remove(Object k)

Removes an element from this set.

Note that the corresponding method of the type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

Specified by:

remove in interface Collection<K>

Specified by:

remove in interface Set<K>
