8. case class GreaterOrEq(left: Value, right: Value) extends Expression with Product with Serializable

   

9. trait LeftTypedColumn[O, E, T] extends TypedCol

   

   Left typed column.

   Left typed column. Contains info about column name and extractor When joining F[L] and F[R], to unsure type safety several types are required. First of all we need to know the original type L to extract value from F container. Second, if L is a tuple of (A, b), we can de-compose extractor into 2 extractors - for A and for B respectively Third, we need to know the column type itself to prevent joining by incompatible types

   O

   original type of left operand in join

   E

   decomposed type, is used when unapplying original extractor

   T

   column type

10. case class Less(left: Value, right: Value) extends Expression with Product with Serializable

    

11. case class LessOrEq(left: Value, right: Value) extends Expression with Product with Serializable

    

12. trait RightTypedColumn[O, E, T] extends TypedCol

    

    Right typed column.

    Right typed column. Contains info about column name and extractor When joining F[L] and F[R], to unsure type safety several types are required. First of all we need to know the original type R to extract value from F container. Second, if R is a tuple of (A, b), we can de-compose extractor into 2 extractors - for A and for B respectively Third, we need to know the column type itself to prevent joining by incompatible types

    O

    original type of right operand in join

    E

    decomposed type, is used when unapplying original extractor
