Package org.jboss.weld.util.collections

Class ImmutableHashSet<T>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractSet<T>

org.jboss.weld.util.collections.ImmutableSet<T>

org.jboss.weld.util.collections.ImmutableHashSet<T>

Type Parameters:

T - the element type

All Implemented Interfaces:

Serializable, Iterable<T>, Collection<T>, Set<T>

public final class ImmutableHashSet<T>
extends ImmutableSet<T>
implements Serializable

Immutable Set implementation. This implementation uses open addressing with linear probing and a table size of the nearest power of two so that load factor is below 0.75. The implementation is inspired by Guava's ImmutableSet implementation.
