public class Object2IntLinkedOpenHashMap<T>
extends Object2IntOpenHashMap<T>
implements Object2IntOrderedMap<T>

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 SortedMap does not support SubMaps of any kind. It implements the interface due to sortability and first/last access
