4. def applyAndOperator[T](a: Option[T], b: Option[T], f: (T, T) ⇒ T): Option[T]

   

   Apply an and operator on Optional parameters, in case one of them is None the non None parameter is returned

   Apply an and operator on Optional parameters, in case one of them is None the non None parameter is returned

   f

   the operator to be applied

5. def applyOrOperator[T](a: Option[T], b: Option[T], f: (T, T) ⇒ T): Option[T]

   

   Apply an or operator on Optional parameters, the operator is applied only if both parameters are defined

   Apply an or operator on Optional parameters, the operator is applied only if both parameters are defined

   f

   the operator to be applied

6. final def asInstanceOf[T0]: T0

   

   Definition Classes

   Any

7. def catalystExprToWrappedExpr(expr: Expression): MetadataWrappedExpression

   

   Converts a catalyst expression to a wrapped expression (recursively)

   Converts a catalyst expression to a wrapped expression (recursively)

   expr

   the catalyst expression to be converted

   returns

   the resulting wrapped expression

   Note

   It's assumed the boolean-operator prefix of the expression tree (that is, from the root down, stopping on non-boolean-operator nodes) is in NNF Form. this is extremely important, since the variant of GenClause and MergeClause used here fail when the NNF condition is not met (simple example (NOT(NOT(X < 5)).
