Type Members

1. sealed trait Bson extends AnyRef

   

   A type-safe ADT for Mongo's native data format.

   A type-safe ADT for Mongo's native data format. Note that this representation is not suitable for efficiently storing large quantities of data.

2. type BsonCursor = AsyncBatchCursor[BsonDocument]

   

3. sealed trait BsonField extends AnyRef

   

4. sealed abstract class BsonType extends AnyRef

   

5. final case class Collection(databaseName: String, collectionName: String) extends Product with Serializable

   

6. final case class Grouped(value: ListMap[Name, Accumulator]) extends Product with Serializable

   

7. sealed trait IdHandling extends AnyRef

   

8. sealed abstract class InputFinder extends AnyRef

   

9. type JavaScriptLog[A] = WriterT[scalaz.Id.Id, JavaScriptPrg, A]

   

10. type JavaScriptLogT[F[_], A] = WriterT[F, JavaScriptPrg, A]

    

11. type JavaScriptPrg = Vector[Stmt]

    

12. final case class MapReduce(map: Expr, reduce: Expr, selection: Option[Selector] = None, inputSort: Option[NonEmptyList[(BsonField, SortDir)]] = None, limit: Option[Long] = None, finalizer: Option[Expr] = None, scope: Scope = ListMap(), jsMode: Option[Boolean] = None, verbose: Option[Boolean] = None) extends Product with Serializable

    

    Configuration parameters for MapReduce operations

    Configuration parameters for MapReduce operations

    map

    The mapping function

    reduce

    The reducing function

    selection

    Query selector to apply to input documents

    inputSort

    Criteria to use to sort the input documents.

    limit

    Limit the number of input documents to map

    finalizer

    JavaScript function applied to the output after the reduce function.

    scope

    Global variables made available to the map, reduce and finalizer functions.

    jsMode

    Whether to avoid converting intermediate values to BSON, leaving them as JavaScript objects instead. Setting this to true has implications on the size of the input, see the MongoDB mapReduce documentation for details.

    verbose

    Whether to include additional information, such as timing, in the results.

    Annotations

14. type MongoDbIOLog[A] = WriterT[MongoDbIO, JavaScriptPrg, A]

    

15. type MongoErrT[F[_], A] = EitherT[F, PhysicalError, A]

21. type WorkflowExecErrT[F[_], A] = EitherT[F, WorkflowExecutionError, A]

    

22. sealed trait WorkflowExecutionError extends AnyRef

    

    Error conditions possible during Workflow execution.

23. sealed trait WorkflowF[+A] extends AnyRef

    

    A Workflow is a graph of atomic operations, with WorkflowOps for the vertices.

    A Workflow is a graph of atomic operations, with WorkflowOps for the vertices. We crush them down into a WorkflowTask. This crush gives us a location to optimize our workflow decisions. EG, A sequence of simple ops may be combined into a single pipeline request, but if one of those operations contains JS, we have to execute that outside of a pipeline, possibly reordering the other operations to avoid having two pipelines with a JS operation in the middle.

    We also implement the optimizations at http://docs.mongodb.org/manual/core/aggregation-pipeline-optimization/ so that we can build others potentially on top of them (including reordering non-pipelines around pipelines, etc.).
