Constructor Detail

• Cursor

  protected Cursor​(CursorableLinkedList parent,
                   int index)

  Constructs a new cursor.

  Parameters:

  index - the index to start from

Method Detail

• remove

  public void remove()

  Removes 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:

  remove in interface Iterator

  Specified by:

  remove in interface ListIterator

  Overrides:

  remove in class AbstractLinkedList.LinkedListIterator

  Throws:

  IllegalStateException - if there is no item to remove

• add

  public void add​(Object obj)

  Adds an object to the list. The object added here will be the new 'previous' in the iterator.

  Specified by:

  add in interface ListIterator

  Overrides:

  add in class AbstractLinkedList.LinkedListIterator

  Parameters:

  obj - the object to add

• nextIndex

  public int nextIndex()

  Gets the index of the next element to be returned.

  Specified by:

  nextIndex in interface ListIterator

  Overrides:

  nextIndex in class AbstractLinkedList.LinkedListIterator

  Returns:

  the next index

• nodeChanged

  protected void nodeChanged​(AbstractLinkedList.Node node)

  Handle event from the list when a node has changed.

  Parameters:

  node - the node that changed

• nodeRemoved

  protected void nodeRemoved​(AbstractLinkedList.Node node)

  Handle event from the list when a node has been removed.

  Parameters:

  node - the node that was removed

• nodeInserted

  protected void nodeInserted​(AbstractLinkedList.Node node)

  Handle event from the list when a node has been added.

  Parameters:

  node - the node that was added

• checkModCount

  protected void checkModCount()

  Override superclass modCount check, and replace it with our valid flag.

  Overrides:

  checkModCount in class AbstractLinkedList.LinkedListIterator

• close

  public void close()

  Mark 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.
