Class CursorableLinkedList.Cursor<E>

    • 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<E>
        Specified by:
        remove in interface ListIterator<E>
        IllegalStateException - if there is no item to remove
      • add

        public void add​(E 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<E>
        obj - the object to add
      • nextIndex

        public int nextIndex()
        Gets the index of the next element to be returned.

        the next index
      • 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.
