    - #### getWorkspaceName

          String getWorkspaceName()

      Get the name of the workspace in which exists all nodes in this batch.
      Returns:
        the workspace name; never null

    - #### rowCount

          long rowCount()

      Get the number of rows in the batch, if that information is available.
      Returns:
        the number of rows; may be equal to -1 if the number of rows is not known without significant overhead

    - #### isEmpty

          boolean isEmpty()

      Determine whether this batch is empty.
      Returns:
        the true if there are no results, or false if there is at least some

    - #### hasNext

          boolean hasNext()

      Determine if there are more rows in this batch.
      Returns:
        true if there are more rows, or false otherwise

    - #### nextRow

          void nextRow()

      Move to the next row in this batch.
      Throws:
        `NoSuchElementException` - if there is no current row
