Type Members

1. class AsyncHandlerGenerator[I, O] extends AnyRef

   So we need to take a type-parameterized request object, package it into a monomorphic case class to send to the worker, and have the handler that receives that object able to pattern match out the parameterized object, all without using reflection.

2. trait AsyncServiceClient[I, O] extends AnyRef

3. class BasicServiceDelegator[C <: CodecDSL] extends DSLDelegator[C]

4. class BasicServiceHandler[C <: CodecDSL] extends ServiceServer[service.BasicServiceHandler.C.Input, service.BasicServiceHandler.C.Output] with DSLHandler[C]

5. sealed trait Callback[+O] extends AnyRef

   A Callback is a Monad for doing in-thread non-blocking operations.

6. case class CallbackExec(cb: () ⇒ Unit, in: Option[FiniteDuration] = scala.None) extends Product with Serializable

7. trait CallbackExecution extends Actor with ActorLogging

8. class CallbackExecutionException extends Exception

   This exception is only thrown when there's a uncaught exception in the execution block of a Callback.

9. case class CallbackExecutor(context: ExecutionContext, executor: ActorRef) extends Product with Serializable

   A CallbackExecutor is an actor that mixes in the [CallbackExecution] trait to complete the execution of a [Callback] that has been converted from a Future.

10. class CallbackPromise[T] extends AnyRef

    A CallbackPromise creates a callback which can be eventually filled in with a value.

11. trait ClientCodecProvider[C <: CodecDSL] extends AnyRef

12. case class ClientConfig(address: InetSocketAddress, requestTimeout: Duration, name: MetricAddress, pendingBufferSize: Int = 100, sentBufferSize: Int = 100, failFast: Boolean = false, connectionAttempts: PollingDuration = ..., idleTimeout: Duration = ...) extends Product with Serializable

    Configuration used to specify a Client's parameters

13. sealed trait ClientConnectionEvent extends ConnectionEvent

14. class ClientOverloadedException extends ServiceClientException

    Thrown when the pending buffer is full

15. class ClientProxy extends Actor with ActorLogging with Stash

    This correctly routes messages to the right worker and handler

16. trait Codec[Output, Input] extends AnyRef

    A Codec is a stateful object for converting requests/responses to/from DataBuffers.

17. trait CodecDSL extends AnyRef

18. trait CodecProvider[C <: CodecDSL] extends AnyRef

    Provide a Codec as well as some convenience functions for usage within in a Service.

19. trait ConnectionContext[C <: CodecDSL] extends AnyRef

    This contains methods to interact with an individual connection.

20. sealed trait ConnectionEvent extends AnyRef

21. class ConnectionLostException extends ServiceClientException

    Thrown when a request is lost in transit

22. case class ConstantCallback[O](value: Try[O]) extends Callback[O] with Product with Serializable

23. abstract class DSLDelegator[C <: CodecDSL] extends Delegator with ServiceContext[C]

24. trait DSLHandler[C <: CodecDSL] extends ServiceServer[service.DSLHandler.C.Input, service.DSLHandler.C.Output] with ConnectionContext[C]

25. class DataException extends ServiceClientException

    Thrown when there's some kind of data error

26. sealed trait DecodedResult[+T] extends AnyRef

27. trait DefaultHandler extends CodecDSL

28. class DefaultTagDecorator[I, O] extends TagDecorator[I, O]

29. class Delayer extends Actor with ActorLogging

    This little actor is needed because apparently actors that are running in a pinned dispatcher AND are sending messages to themselves (like workers) cannot use the scheduler.

30. class DroppedReply extends Error

31. class FatalServiceServerException extends ServiceServerException

32. class LoadBalancingClient[I, O] extends ServiceClientLike[I, O] with WorkerItem

    The LoadBalancingClient will evenly distribute requests across a set of clients.

33. class LoadBalancingClientException extends Exception

34. case class MappedCallback[I, O](trigger: ((Try[I]) ⇒ Unit) ⇒ Unit, handler: (Try[I]) ⇒ Try[O]) extends Callback[O] with Product with Serializable

35. trait MessageDecoder[T] extends AnyRef

36. trait MessageEncoder[T] extends AnyRef

37. class NotConnectedException extends ServiceClientException

    Throw when a request is attempted while not connected

38. class PermutationGenerator[T] extends Iterator[List[T]]

    The PermutationGenerator creates permutations such that consecutive calls are guaranteed to cycle though all items as the first element.

39. class PromiseException extends Exception

40. class ReceiveException extends Exception

41. class RequestBufferFullException extends ServiceServerException

42. trait RequestFormatter[I] extends AnyRef

43. class RequestTimeoutException extends ServiceClientException

    Returned when a request has been pending for too long

44. class SendFailedException extends Exception

45. class ServiceClient[I, O] extends Controller[O, I] with ClientConnectionHandler with ServiceClientLike[I, O] with ManualUnbindHandler

    A ServiceClient is a non-blocking, synchronous interface that handles sending atomic commands on a connection and parsing their replies

46. class ServiceClientException extends Exception

47. trait ServiceClientLike[I, O] extends AnyRef

48. class ServiceClientPool[I, O, T <: ServiceClient[I, O]] extends AnyRef

    A ClientPool is a simple container of open connections.

49. case class ServiceConfig[I, O](name: MetricAddress, requestTimeout: Duration, requestBufferSize: Int = 100, logErrors: Boolean = true, requestLogFormat: Option[RequestFormatter[I]] = scala.None, requestMetrics: Boolean = true) extends Product with Serializable

    Configuration class for a Service Server Connection Handler

50. trait ServiceContext[C <: CodecDSL] extends AnyRef

51. abstract class ServiceServer[I, O] extends Controller[I, O] with ServerConnectionHandler

    The ServiceServer provides an interface and basic functionality to create a server that processes requests and returns responses over a codec.

52. class ServiceServerException extends Exception

53. class StaleClientException extends Exception

    This is thrown when a Client is manually disconnected, and subsequent attempt is made to reconnect.

54. trait TagDecorator[I, O] extends AnyRef

55. class UnhandledRequestException extends Exception

56. case class UnmappedCallback[I](trigger: ((Try[I]) ⇒ Unit) ⇒ Unit) extends Callback[I] with Product with Serializable

    UnmappedCallback is essentially an optimization that avoids needing to create a MappedCallback with an identity function
