class ProductClassShape[E <: Product, C <: Product] extends MappedScalaProductShape[FlatShapeLevel, Product, C, E, C]

A generic Product class shape that can be used to lift a class of plain Scala types to a class of lifted types. This allows the type to be used as a record type (like tuples and HLists) in the Lifted Embedding.

This can help with mapping tables >22 columns to classes, especially when using code generation. This can be used for Scala 2.11 case classes >22 fields.

Example:

def columnShape[T](implicit s: Shape[FlatShapeLevel, Column[T], T, Column[T]]) = s
class C(val a: Int, val b: Option[String]) extends Product{
  def canEqual(that: Any): Boolean = that.isInstanceOf[C]
  def productArity: Int = 2
  def productElement(n: Int): Any = Seq(a, b)(n)
}
class LiftedC(val a: Column[Int], val b: Column[Option[String]]) extends Product{
  def canEqual(that: Any): Boolean = that.isInstanceOf[LiftedC]
  def productArity: Int = 2
  def productElement(n: Int): Any = Seq(a, b)(n)
}
implicit object cShape extends ProductClassShape(
  Seq(columnShape[Int], columnShape[Option[String]]),
  seq => new LiftedC(seq(0).asInstanceOf[Column[Int]], seq(1).asInstanceOf[Column[Option[String]]]),
  seq => new C(seq(0).asInstanceOf[Int], seq(1).asInstanceOf[Option[String]])
)
