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

11. case class ClientConfig(address: InetSocketAddress, requestTimeout: Duration, name: MetricAddress, pendingBufferSize: Int = 100, sentBufferSize: Int = 20, failFast: Boolean = false, connectionAttempts: PollingDuration = ..., idleTimeout: Duration = ...) extends Product with Serializable

    Configuration used to specify a Client's parameters

12. sealed trait ClientConnectionEvent extends ConnectionEvent

13. class ClientOverloadedException extends ServiceClientException

    Thrown when the pending buffer is full

14. class ClientProxy extends Actor with ActorLogging with Stash

    This correctly routes messages to the right worker and handler

15. trait Codec[Output, Input] extends AnyRef

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

16. trait CodecDSL extends AnyRef

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

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

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

19. sealed trait ConnectionEvent extends AnyRef

20. class ConnectionLostException extends ServiceClientException

    Thrown when a request is lost in transit

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

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

23. class DataException extends ServiceClientException

    Thrown when there's some kind of data error

24. sealed trait DecodedResult[+T] extends AnyRef

25. trait DefaultHandler extends CodecDSL

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

27. 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.

28. class DroppedReply extends Error

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

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

30. class LoadBalancingClientException extends Exception

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

32. trait MessageDecoder[T] extends AnyRef

33. trait MessageEncoder[T] extends AnyRef

34. class NotConnectedException extends ServiceClientException

    Throw when a request is attempted while not connected

35. 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.

36. class ReceiveException extends Exception

37. class RequestBufferFullException extends Exception

38. class RequestTimeoutException extends ServiceClientException

    Returned when a request has been pending for too long

39. class SendFailedException extends Exception

40. 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

41. class ServiceClientException extends Exception

42. trait ServiceClientLike[I, O] extends AnyRef

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

    A ClientPool is a simple container of open connections.

44. case class ServiceConfig(name: MetricAddress, requestTimeout: Duration, requestBufferSize: Int = 100, logErrors: Boolean = true) extends Product with Serializable

    Configuration class for a Service Server Connection Handler

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

46. abstract class ServiceServer[I, O] extends Controller[I, O]

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

47. class StaleClientException extends Exception

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

48. trait TagDecorator[I, O] extends AnyRef

49. class UnhandledRequestException extends Exception

50. 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
