abstract class Shape[Level <: ShapeLevel, -Mixed_, Unpacked_, Packed_] extends AnyRef

A type class that encodes the unpacking Mixed => Unpacked of a Query[Mixed] to its result element type Unpacked and the packing to a fully packed type Packed, i.e. a type where everything which is not a transparent container is wrapped in a Column[_].

Example:

  • Mixed: (Column[Int], Column[(Int, String)], (Int, Option[Double]))
  • Unpacked: (Int, (Int, String), (Int, Option[Double]))
  • Packed: (Column[Int], Column[(Int, String)], (Column[Int], Column[Option[Double]]))
  • Linearized: (Int, Int, String, Int, Option[Double])

  3. type Unpacked = Unpacked_

Abstract Value Members

  1. abstract def buildParams(extract: (Any) => Unpacked): Packed

    Build a packed representation containing QueryParameters that can extract data from the unpacked representation later.

    Build a packed representation containing QueryParameters that can extract data from the unpacked representation later. This method is not available for shapes where Mixed and Unpacked are different types.

  2. abstract def encodeRef(value: Mixed, path: Node): Any

    Encode a reference into a value of this Shape.

    Encode a reference into a value of this Shape. This method may not be available for shapes where Mixed and Packed are different types.

  3. abstract def pack(value: Mixed): Packed

    Convert a value of this Shape's (mixed) type to the fully packed type

  4. abstract def packedShape: Shape[Level, Packed, Unpacked, Packed]

    Return the fully packed Shape

  5. abstract def toNode(value: Mixed): Node

    Return an AST Node representing a mixed value.

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.
