Class CanonicalizingHashSet<E>

java.lang.Object

com.hazelcast.aggregation.impl.CanonicalizingHashSet<E>

Type Parameters:

E - the element type.

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable, Iterable<E>, Collection<E>, Set<E>

public final class CanonicalizingHashSet<E>
extends Object
implements Set<E>, IdentifiedDataSerializable

A read-only hash set that canonicalizes its mixed-type numeric elements for lookup operations while still preserving the original element values.

That canonicalization logic is required for the consistency with the mixed-type numeric equality logic used inside query engine.
