    Description copied from interface: NullPredicate
    
    If this predicate represents a simple a == null or a != null predicate on the mapped value, then this method may choose to return a special value so that the predicate may be short-circuited. The method may always return NullPredicateType.OTHER, in which case no such optimization can be done.
