class Attribute[T] extends AnyRef

Attribute interface to collect and check statistics. Included support of different combinations of collected parameters: count, min/max, and set of values through bit vector. Here are some common flags: 7 - enable all parameters, 1 - enable count, 6 - enable min/max and set. In order to create attribute comparison function is required similar the lt function used in sortWith method. Name must unique to the attribute.

    Check if value is in min-max range, if mode is enabled, otherwise None

    Check if value is in set, if mode is enabled, otherwise None

  9. def containsNull(): Boolean

    Whether or not attribute has null values.

    Whether or not attribute has null values. It checks initial state of min, max and set, and tracks values being added, thus overall nullability is cumulative effect of states.
