  6. def constructIsNotNullConstraints(constraints: Set[Expression], output: Seq[Attribute]): Set[Expression]

    Infers a set of isNotNull constraints from null intolerant expressions as well as non-nullable attributes.

    Infers a set of isNotNull constraints from null intolerant expressions as well as non-nullable attributes. For e.g., if an expression is of the form (a > 5), this returns a constraint of the form isNotNull(a)

  12. def inferAdditionalConstraints(constraints: Set[Expression]): Set[Expression]

    Infers an additional set of constraints from a given set of equality constraints.

    Infers an additional set of constraints from a given set of equality constraints. For e.g., if an operator has constraints of the form (a = 5, a = b), this returns an additional constraint of the form b = 5.
