    • Method Detail

      • next

        T next()
        Get the next item in the sequence.
        Specified by:
        next in interface SequenceIterator<T extends Item>
        Returns:
        the next Item. If there are no more nodes, return null.
      • current

        T current()
        Get the current item in the sequence.
        Specified by:
        current in interface SequenceIterator<T extends Item>
        Returns:
        the current item, that is, the item most recently returned by next()
      • position

        int position()
        Get the current position
        Specified by:
        position in interface SequenceIterator<T extends Item>
        Returns:
        the position of the current item (the item most recently returned by next()), starting at 1 for the first node
      • getAnother

        UnfailingIterator<T> getAnother()
        Get another iterator over the same sequence of items, positioned at the start of the sequence. It must be possible to call this method at any time, whether none, some, or all of the items in the original iterator have been read. The method is non-destructive: it does not change the state of the original iterator.
        Specified by:
        getAnother in interface SequenceIterator<T extends Item>
        Returns:
        a new iterator over the same sequence
