An extensible list iterator implementation.

  • Constructor Details

    • EListIterator

      public EListIterator()
      Creates an instance.

    • EListIterator

      public EListIterator(int index)
      Creates an instance advanced to the index.
      Parameters:
      index - the starting index.

  • Method Details

    • hasPrevious

      public boolean hasPrevious()
      Returns whether there are more objects for previous(). Returns whether there are more objects.
      Specified by:
      hasPrevious in interface ListIterator<E1>

    • previous

      public E1 previous()
      Returns the previous object and advances the iterator. This implementation delegates to doPrevious.
      Specified by:
      previous in interface ListIterator<E1>
      Returns:
      the previous object.
      Throws:
      NoSuchElementException - if the iterator is done.

    • doPrevious

      protected E doPrevious()
      Returns the previous object and advances the iterator. This implementation delegates to get.
      Returns:
      the previous object.
      Throws:
      NoSuchElementException - if the iterator is done.

    • nextIndex

      public int nextIndex()
      Returns the index of the object that would be returned by calling next.
      Specified by:
      nextIndex in interface ListIterator<E1>
      Returns:
      the index of the object that would be returned by calling next.

    • previousIndex

      public int previousIndex()
      Returns the index of the object that would be returned by calling previous.
      Specified by:
      previousIndex in interface ListIterator<E1>
      Returns:
      the index of the object that would be returned by calling previous.

    • set

      public void set(E1 object)
      Sets the object at the index of the last call to next or previous. This implementation delegates to set.
      Specified by:
      set in interface ListIterator<E1>
      Parameters:
      object - the object to set.
      Throws:
      IllegalStateException - if next or previous have not yet been called, or remove or add have already been called after the last call to next or previous.

    • doSet

      protected void doSet(E object)
      Sets the object at the index of the last call to next or previous. This implementation delegates to set.
      Parameters:
      object - the object to set.
      Throws:
      IllegalStateException - if next or previous have not yet been called, or remove or add have already been called after the last call to next or previous.

    • add

      public void add(E1 object)
      Adds the object at the next index and advances the iterator past it. This implementation delegates to doAdd(E).
      Specified by:
      add in interface ListIterator<E1>
      Parameters:
      object - the object to add.

    • doAdd

      protected void doAdd(E object)
      Adds the object at the next index and advances the iterator past it. This implementation delegates to add(int, E).
      Parameters:
      object - the object to add.
