All Implemented Interfaces:

Serializable, Iterable<E>, Collection<E>, Set<E>

public class NullAllowingImmutableSet<E>
extends AbstractSet<E>
implements Serializable

An immutable set that allows null elements.

This implementation is intended for low cardinalities, query operations have linear performance. Insertion order is preserved.

builder

public static <E> NullAllowingImmutableSet.Builder<E> builder()

Returns a builder to create a new instance, with the default expected size (16). The returned builder is not thread-safe.

builder

public static <E> NullAllowingImmutableSet.Builder<E> builder(int expectedSize)

Returns a builder to create a new instance. The returned builder is not thread-safe.

Parameters:

expectedSize - the number of expected elements in the set. This is used to pre-size internal data structures (if the builder ends up having more elements, it resizes automatically).
