public class ObjectOpenHashSet<T>
extends AbstractObjectSet<T>
implements ITrimmable

A Type Specific Custom implementation of the HashSet Instead of using Wrapper Object Arrays for storing keys and values there is dedicated arrays for storing keys. Extra to that there is a couple quality of life functions provided
