public class DoubleLinkedOpenHashSet
extends DoubleOpenHashSet
implements DoubleOrderedSet

A Type Specific LinkedHashMap implementation that uses specific arrays to create links between nodes to remove the wrapping of elements to greatly reduce memory usage. In Addition adding some helper methods to move around elements. This implementation of SortedSet does not support SubSet of any kind. It implements the interface due to sortability and first/last access
