`protected AbstractLinkedList.Node`	`getLastNodeReturned()`	Gets the last node returned.
`boolean`	`hasNext()`
`boolean`	`hasPrevious()`	Checks to see if there is a previous element that can be iterated to.
`Object`	`next()`

- Field Detail
  - parent
```
protected final AbstractLinkedList parent
```
    The parent list
  - next
```
protected AbstractLinkedList.Node next
```
    The node that will be returned by next(). If this is equal to AbstractLinkedList.header then there are no more values to return.
  - nextIndex
```
protected int nextIndex
```
    The index of next.
  - current
```
protected AbstractLinkedList.Node current
```
    The last node that was returned by 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.
  - expectedModCount
```
protected int expectedModCount
```
    The modification count that the list is expected to have. If the list doesn't have this count, then a ConcurrentModificationException may be thrown by the operations.

protected LinkedListIterator(AbstractLinkedList parent,
                             int fromIndex)
                      throws IndexOutOfBoundsException
```
    Create a ListIterator for a list.
    
    Parameters:
    
    parent - the parent list
    
    fromIndex - the index to start at
    
    Throws:
    
    IndexOutOfBoundsException
- Method Detail
  - checkModCount
```
protected void checkModCount()
```
    Checks the modification count of the list is the value that this object expects.
    
    Throws:
    
    ConcurrentModificationException - If the list's modification count isn't the value that was expected.
  - getLastNodeReturned
```
protected AbstractLinkedList.Node getLastNodeReturned()
                                               throws IllegalStateException
```
    Gets the last node returned.
    
    Throws:
    
    IllegalStateException - 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).

    hasPrevious in interface ListIterator
    
    Specified by:
    
    hasPrevious in interface OrderedIterator
