  • Method Details

    • isUngroupable

      static boolean isUngroupable(ColumnSource<?> source)

      Parameters:
      source - the source to check
      Returns:
      true if the column source is an UngroupableColumnSource and it is ungroupable

    • isUngroupable

      boolean isUngroupable()
      Does this particular ColumnSource support ungrouping?
      Returns:
