public interface OrderedIterator<E> extends Iterator<E>
Defines an iterator that operates over an ordered container. Subset of `ListIterator`.

This iterator allows both forward and reverse iteration through the container.

  - ### hasPrevious

    boolean hasPrevious()
    Checks to see if there is a previous element that can be iterated to.
    Returns:
      `true` if the iterator has a previous element

  - ### previous

    E previous()
    Gets the previous element from the container.
    Returns:
      the previous element in the iteration
    Throws:
      `NoSuchElementException` - if the iteration is finished
