    Description copied from interface: Selector
    
    Is true if Selector.isCountable() is false or if this selector is in random order (for most cases). Is never true when this selector is in shuffled order (which is less scalable but more exact).
    
    Returns:
    
    true if the Iterator.hasNext() of the Iterator created by Iterable.iterator() never returns false (except when it's empty).
