```
public class HistoricalHashSet<E>
extends AbstractHistoricalCollection<E,java.util.LinkedHashSet<E>>
implements HistoricalSet<E>
```
LinkedHashSet-valued historical state. The current hash set is always maintained, and past states of the hash set are obtained by applying the events between now and the requested time in reverse.

The Iterator returned by this class does not support the remove() method. Any returned subset is unmodifiable.
