Type Members

1. case class Dependants[P <: Platform[P]](tail: Producer[P, _]) extends Product with Serializable

   Producers are Directed Acyclic Graphs by the fact that they are immutable.

2. case class FlatMappedProducer[P <: Platform[P], T, U](producer: Producer[P, T], fn: (T) ⇒ TraversableOnce[U]) extends Producer[P, U] with Product with Serializable

3. case class IdentityKeyedProducer[P <: Platform[P], K, V](producer: Producer[P, (K, V)]) extends KeyedProducer[P, K, V] with Product with Serializable

4. sealed trait KeyedProducer[P <: Platform[P], K, V] extends Producer[P, (K, V)]

5. case class LeftJoinedProducer[P <: Platform[P], K, V, JoinedV](left: KeyedProducer[P, K, V], joined: P.Service[K, JoinedV]) extends KeyedProducer[P, K, (V, Option[JoinedV])] with Product with Serializable

6. case class MergedProducer[P <: Platform[P], T](left: Producer[P, T], right: Producer[P, T]) extends Producer[P, T] with Product with Serializable

7. case class NamedProducer[P <: Platform[P], T](producer: Producer[P, T], id: String) extends Producer[P, T] with Product with Serializable

8. case class OptionMappedProducer[P <: Platform[P], T, U](producer: Producer[P, T], fn: (T) ⇒ Option[U], manifest: Manifest[U]) extends Producer[P, U] with Product with Serializable

   Represents filters and maps which may be optimized differently Note that "option-mapping" is closed under composition and hence useful to call out

9. class OptionalPlatform2[P1 <: Platform[P1], P2 <: Platform[P2]] extends Platform[OptionalPlatform2[P1, P2]]

   Platform capable of planning and executing at most 2 underlying platforms in parallel.

10. case class OptionalUnzip2[P1 <: Platform[P1], P2 <: Platform[P2]]() extends Product with Serializable

11. class Options extends AnyRef

12. trait Platform[P <: Platform[P]] extends AnyRef

    Base trait for summingbird compilers.

13. class Platform2[P1 <: Platform[P1], P2 <: Platform[P2]] extends Platform[Platform2[P1, P2]]

    Platform capable of planning and executing two underlying platforms in parallel.

14. sealed trait Producer[P <: Platform[P], T] extends AnyRef

    A Producer is a node in our tree, able to generate new items and have operations applied to it.

15. case class Source[P <: Platform[P], T](source: P.Source[T], manifest: Manifest[T]) extends Producer[P, T] with Product with Serializable

16. case class Summer[P <: Platform[P], K, V](producer: KeyedProducer[P, K, V], store: P.Store[K, V], monoid: Monoid[V]) extends KeyedProducer[P, K, V] with Product with Serializable

17. trait TimeExtractor[T] extends (T) ⇒ Long with Serializable

18. case class Unzip2[P1 <: Platform[P1], P2 <: Platform[P2]]() extends Product with Serializable

    I tried to make Unzip2 an object with an apply method that took all three type parameters, but ran into issues:

19. case class WrittenProducer[P <: Platform[P], T](producer: Producer[P, T], sink: P.Sink[T]) extends Producer[P, T] with Product with Serializable
