Interface CharSet

All Superinterfaces:

CharCollection, CharIterable, Collection<Character>, Iterable<Character>, Set<Character>

All Known Subinterfaces:

CharSortedSet

All Known Implementing Classes:

AbstractCharSet, AbstractCharSortedSet, CharArraySet, CharAVLTreeSet, CharLinkedOpenCustomHashSet, CharLinkedOpenHashSet, CharOpenCustomHashSet, CharOpenHashSet, CharRBTreeSet, CharSets.EmptySet, CharSets.Singleton, CharSets.SynchronizedSet, CharSets.UnmodifiableSet, CharSortedSets.EmptySet, CharSortedSets.Singleton, CharSortedSets.SynchronizedSortedSet, CharSortedSets.UnmodifiableSortedSet

public interface CharSet
extends CharCollection, Set<Character>

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

CharIterator 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 CharCollection

Specified by:

iterator in interface CharIterable

Specified by:

iterator in interface Collection<Character>

Specified by:

iterator in interface Iterable<Character>

Specified by:

iterator in interface Set<Character>

Returns:

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

See Also:

Iterable.iterator()

remove

boolean remove(char 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 CharCollection

Specified by:

add

@Deprecated
default boolean add(Character o)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

add in interface CharCollection

Specified by:

Specified by:

add in interface Set<Character>

contains

@Deprecated
default boolean contains(Object o)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

contains in interface CharCollection

Specified by:

contains in interface Collection<Character>

Specified by:

contains in interface Set<Character>

rem

@Deprecated
default boolean rem(char 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 CharCollection

See Also:

Collection.remove(Object)

of

@SafeVarargs
static CharSet of(char... a)

Creates a new set using a list of elements.

Parameters:

a - a list of elements that will be used to initialize the new set.
