public interface IntSet
extends it.unimi.dsi.fastutil.ints.IntCollection, java.util.Set<java.lang.Integer>

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

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

Set

Method Detail

iterator

it.unimi.dsi.fastutil.ints.IntIterator iterator()

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

Specified by:

iterator in interface java.util.Collection<java.lang.Integer>

Specified by:

iterator in interface it.unimi.dsi.fastutil.ints.IntCollection

Specified by:

iterator in interface it.unimi.dsi.fastutil.ints.IntIterable

Specified by:

iterator in interface java.lang.Iterable<java.lang.Integer>

Specified by:

iterator in interface java.util.Set<java.lang.Integer>

Returns:

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

spliterator

default it.unimi.dsi.fastutil.ints.IntSpliterator spliterator()

Returns a type-specific spliterator on the elements of this set.

Set spliterators must report at least Spliterator.DISTINCT.

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 it.unimi.dsi.fastutil.ints.IntCollection

of

static IntSet of()

Returns an immutable empty set.

Returns:

an immutable empty set.

of

static IntSet of(int e)

Returns:

an immutable set containing e.

of

static IntSet of(int e0,
                 int e1)

Returns an immutable set with the elements given.

Parameters:

e0 - the first element.

e1 - the second element.

Returns:

an immutable set containing e0 and e1.

Throws:

java.lang.IllegalArgumentException - if there were duplicate entries.

of

static IntSet of(int e0,
                 int e1,
                 int e2)

Returns an immutable set with the elements given.

Parameters:

e0 - the first element.

e1 - the second element.

e2 - the third element.

Returns:

of

static IntSet of(int... a)

Returns an immutable list with the elements given.

Parameters:

a - the list of elements that will be in the final set.

Returns:

an immutable set containing the elements in a.

Throws:

java.lang.IllegalArgumentException - if there are any duplicate entries.
