getReferenceCacheNode

public LinkedNode getReferenceCacheNode()

setReferenceCacheNode

public void setReferenceCacheNode(LinkedNode referenceNode)

getReferenceCache

public ExposedNodeLinkedList getReferenceCache()

updateAccess

public void updateAccess()

Notifies that cache key that it has been accessed. Allows the LRU sub-cache to be maintained, the cache node must be moved to the front of the list.
