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])
- Annotations
- @implicitNotFound("No matching Shape found.\nSlick does not know how to map the given types.\nPossible causes: T in Table[T] does not match your * projection,\n you use an unsupported type in a Query (e.g. scala List),\n or you forgot to import a driver api into scope.\n Required level: ${Level}\n Source type: ${Mixed_}\n Unpacked type: ${Unpacked_}\n Packed type: ${Packed_}\n")

Abstract Value Members
- 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.
- 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.
- abstract def pack(value: Mixed): Packed
Convert a value of this Shape's (mixed) type to the fully packed type
- abstract def packedShape: Shape[Level, Packed, Unpacked, Packed]
Return the fully packed Shape
- abstract def toNode(value: Mixed): Node
Return an AST Node representing a mixed value.
