public interface LazyLongSkippableIterator extends LazyLongIterator
A skippable lazy iterator over longs.

      long skipTo(long lowerBound)
      Skips to a given element.

      Note that this interface is fragile: after END_OF_LIST has been returned, the behavour of further calls to this method will be unpredictable.

      Parameters:
      lowerBound - a lower bound to the returned element.
      Returns:
      if the last returned element is greater than or equal to lowerBound, the last returned element; otherwise, the smallest element greater than or equal to lowerBound that would be returned by this iterator, or END_OF_LIST if no such element exists.
