Class AggregateSetFactory<V>

public class AggregateSetFactory<V> extends SetFactory<V> implements Serializable

AggregateSetFactory uses a single HashMap as backing store for the many smaller Sets created by this SetFactory. This means that we use much less space and rehash less frequently than if we were using the standard hashSetFactory.
