  • Field Details

    • cursor

      protected int cursor
      The current position of the iterator.

    • lastCursor

      protected int lastCursor
      The previous position of the iterator.

    • expectedModCount

      protected int expectedModCount
      The modification count of the containing list.

  • Constructor Details

    • EIterator

      protected EIterator()

  • Method Details

    • hasNext

      public boolean hasNext()
      Returns whether there are more objects.
      Specified by:
      hasNext in interface Iterator<E1>
      Returns:
      whether there are more objects.

    • next

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

    • doNext

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

    • remove

      public void remove()
      Removes the last object returned by next() from the list, it's an optional operation. This implementation can also function in a list iterator to act upon on the object returned by calling previous.
      Specified by:
      remove in interface Iterator<E1>
      Throws:
      IllegalStateException - if next has not yet been called, or remove has already been called after the last call to next.

    • checkModCount

      protected void checkModCount()
      Checks that the modification count is as expected.
      Throws:
      ConcurrentModificationException - if the modification count is not as expected.
