Type Parameters:

V - the keyType of elements maintained by this Collection

public class Char2ObjectLinkedOpenCustomHashMap<V>
extends Char2ObjectOpenCustomHashMap<V>
implements Char2ObjectOrderedMap<V>

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
