  • abstract class AbstractTypedColumn[T, U] extends UntypedExpression[T]

    Generic representation of a typed column.

    Generic representation of a typed column. A typed column can either be a TypedAggregate or a frameless.TypedColumn.

    T

    phantom type representing the dataset on which this columns is selected. When T = A with B the selection is on either A or B.

    U

    type of column

trait Mapper[X] extends AnyRef

A helper class to make to simplify working with Optional fields.

val x: TypedColumn[Option[Int]] = _
x.opt.map(_*2) // This only compiles if the type of x is Option[X] (in this example X is of type Int)
Note

Known issue: map() will NOT work when the applied function is a udf(). It will compile and then throw a runtime error.
