    - #### isCountable

          public boolean isCountable()

      Description copied from interface: `Selector`
      If false, then `Selector.isNeverEnding()` is true.
      Returns:
        true if all the `ValueRange`s are countable (for example a double value range between 1.2 and 1.4 is not countable)
