      Throws:
      X

    • hasNext

      public final boolean hasNext() throws X

      Returns:
      true if the iteration has more elements.
      Throws:
      X

    • next

      public final E next() throws X
      Deprecated.

      Returns:
      the next element in the iteration.
      Throws:
      X

    • lookAhead

      private E lookAhead() throws X
      Deprecated.
      Fetches the next element if it hasn't been fetched yet and stores it in nextElement.
      Returns:
      The next element, or null if there are no more results.
      Throws:
      X - If there is an issue getting the next element or closing the iteration.

      public final void close() throws X
      Deprecated.
      Description copied from interface: CloseableIteration
      Closes this iteration, freeing any resources that it is holding. If the iteration has already been closed then invoking this method has no effect.
