. If this is equal
to AbstractLinkedList.header
then there are no more values to return.
protected int nextIndex

next()
or previous()
. Set to null
if next()
or previous()
haven't been called, or if the node has been removed
with remove()
or a new node added with add(Object)
.
Should be accessed through getLastNodeReturned()
to enforce
this behaviour.
