void |
close()
Mark this cursor as no longer being needed.

nextIndex()
Gets the index of the next element to be returned.
|
protected void |
nodeChanged(AbstractLinkedList.Node<E> node)
Handle event from the list when a node has changed.
|
protected void |
nodeInserted(AbstractLinkedList.Node<E> node)
Handle event from the list when a node has been added.
|
protected void |

There may have been subsequent alterations to the list since you obtained this item, however you can still remove it. You can even remove it if the item is no longer in the main list. However, you can't call this method on the same iterator more than once without calling next() or previous().
