Interface IntSet

All Superinterfaces:

Collection<Integer>, IntCollection, IntIterable, Iterable<Integer>, Set<Integer>

All Known Subinterfaces:

IntSortedSet

All Known Implementing Classes:

AbstractIntSet, AbstractIntSortedSet, IntArraySet, IntAVLTreeSet, IntLinkedOpenCustomHashSet, IntLinkedOpenHashSet, IntOpenCustomHashSet, IntOpenHashBigSet, IntOpenHashSet, IntRBTreeSet, IntSets.EmptySet, IntSets.Singleton, IntSets.SynchronizedSet, IntSets.UnmodifiableSet, IntSortedSets.EmptySet, IntSortedSets.Singleton, IntSortedSets.SynchronizedSortedSet, IntSortedSets.UnmodifiableSortedSet

public interface IntSet
extends IntCollection, Set<Integer>

A type-specific Set; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this interface strengthens (again) iterator().

Set

Method Details

iterator

IntIterator 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<Integer>

Specified by:

iterator in interface IntCollection

Specified by:

iterator in interface IntIterable

Specified by:

iterator in interface Iterable<Integer>

Specified by:

iterator in interface Set<Integer>

Returns:

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

See Also:

Iterable.iterator()

remove

boolean remove(int k)

Removes an element from this set.

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

See Also:

Collection.remove(Object)

remove

@Deprecated default boolean remove(Object o)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

remove in interface Collection<Integer>

Specified by:

remove in interface Set<Integer>

add

@Deprecated default boolean add(Integer o)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

add in interface Collection<Integer>

contains

@Deprecated default boolean contains(Object o)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

contains in interface Collection<Integer>

Specified by:

contains in interface IntCollection

Specified by:

contains in interface Set<Integer>

rem

@Deprecated default boolean rem(int k)

Deprecated.

Please use remove() instead.

Removes an element from this set.

This method is inherited from the type-specific collection this type-specific set is based on, but it should not used as this interface reinstates remove() as removal method.

Specified by:

rem in interface IntCollection
