    • Field Detail

      • parent

        private final TreeList<E> parent
        The parent list

      • nextIndex

        private int nextIndex
        The index of the next node to be returned.

      • currentIndex

        private int currentIndex
        The index of the last node that was returned.

      • expectedModCount

        private int expectedModCount
