All Implemented Interfaces:

public class Int2IntLinkedOpenCustomHashMap
extends Int2IntOpenCustomHashMap
implements Int2IntSortedMap

A Type Specific LinkedHashMap that allows for custom HashControl. That uses arrays to create links between nodes. For cases where Objects/primitive do not allow hashcoding this can be really useful and provide a lot of control. This implementation of SortedMap does not support SubMaps of any kind. It implements the interface due to sortability and first/last access
