Constructor Details- 
CursorConstructs a new cursor.- Parameters:
- parent- the parent list
- index- the index to start from
 
 
- 
- 
Method Details- 
addAdds an object to the list. The object added here will be the new 'previous' in the iterator.- Specified by:
- addin interface- ListIterator<E>
- Overrides:
- addin class- AbstractLinkedList.LinkedListIterator<E>
- Parameters:
- obj- the object to add
 
- 
checkModCountOverride superclass modCount check, and replace it with our valid flag.- Overrides:
- checkModCountin class- AbstractLinkedList.LinkedListIterator<E>
 
- 
closeMark this cursor as no longer being needed. Any resources associated with this cursor are immediately released. In previous versions of this class, it was mandatory to close all cursor objects to avoid memory leaks. It is no longer necessary to call this close method; an instance of this class can now be treated exactly like a normal iterator.
- 
nextIndexGets the index of the next element to be returned.- Specified by:
- nextIndexin interface- ListIterator<E>
- Overrides:
- nextIndexin class- AbstractLinkedList.LinkedListIterator<E>
- Returns:
- the next index
 
- 
nodeChangedHandle event from the list when a node has changed.- Parameters:
- node- the node that changed
 
- 
nodeInsertedHandle event from the list when a node has been added.- Parameters:
- node- the node that was added
 
- 
nodeRemovedHandle event from the list when a node has been removed.- Parameters:
- node- the node that was removed
 
- 
removeRemoves the item last returned by this iterator.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(). - Specified by:
- removein interface- Iterator<E>
- Specified by:
- removein interface- ListIterator<E>
- Overrides:
- removein class- AbstractLinkedList.LinkedListIterator<E>
- Throws:
- IllegalStateException- if there is no item to remove
