Type Members

1. trait AggregateTypes[V, U <: HList] extends AnyRef

   

   A type class to extract the column types out of an HList of frameless.TypedAggregate.

   A type class to extract the column types out of an HList of frameless.TypedAggregate.

   Example:

   1. type U = TypedAggregate[T,A] :: TypedAggregate[T,B] :: TypedAggregate[T,C] :: HNil
      type Out = A :: B :: C :: HNil

   Note

   This type class is mostly a workaround to issue with slow implicit derivation for Comapped.

2. class As[T, U] extends AnyRef

   

3. trait ColumnTypes[T, U <: HList] extends AnyRef

   

   A type class to extract the column types out of an HList of frameless.TypedColumn.

   A type class to extract the column types out of an HList of frameless.TypedColumn.

   Example:

   1. type U = TypedColumn[T,A] :: TypedColumn[T,B] :: TypedColumn[T,C] :: HNil
      type Out = A :: B :: C :: HNil

   Note

   This type class is mostly a workaround to issue with slow implicit derivation for Comapped.

4. class GroupedBy1Ops[K1, V] extends AnyRef

   

5. class GroupedBy2Ops[K1, K2, V] extends AnyRef

   

6. class GroupedByManyOps[T, TK <: HList, K <: HList, KT] extends AnyRef

   

7. final case class Pivot[T, GroupedColumns <: HList, PivotType, Values <: HList](ds: TypedDataset[T], groupedBy: GroupedColumns, pivotedBy: TypedColumn[T, PivotType], values: Values) extends Product with Serializable

   

   Represents a typed Pivot operation.

8. final case class PivotNotValues[T, GroupedColumns <: HList, PivotType](ds: TypedDataset[T], groupedBy: GroupedColumns, pivotedBy: TypedColumn[T, PivotType]) extends ProductArgs with Product with Serializable

   

9. trait Repeat[L <: HList, N <: Nat] extends AnyRef

   

   Typeclass supporting repeating L-typed HLists N times.

   Typeclass supporting repeating L-typed HLists N times.

   Repeat[Int :: String :: HNil, Nat._2].Out =:= Int :: String :: Int :: String :: HNil

10. case class SmartProject[T, U](apply: (TypedDataset[T]) ⇒ TypedDataset[U])(implicit evidence$1: TypedEncoder[T], evidence$2: TypedEncoder[U]) extends Product with Serializable
