Class BitSetIntSet

java.lang.Object

java.util.AbstractCollection<E>

org.apache.ignite.internal.util.GridSerializableCollection<Integer>

org.apache.ignite.internal.util.collection.BitSetIntSet

All Implemented Interfaces:

Serializable, Iterable<Integer>, Collection<Integer>, Set<Integer>, IntSet

public class BitSetIntSet
extends GridSerializableCollection<Integer>
implements IntSet

Set of Integers implementation based on BitSet. Implementation doesn't support negative values and null, cause we can't distinct null from 0 bit in BitSet.
