Type Members

1. trait SessionOpenTodayStore extends AnyRef

   

   This is needed to determine if the session has opened today or not.

   This is needed to determine if the session has opened today or not. For instance, if it is a long running process, then it knows already, but if you bounce it every nightr and maybe your ctrl-m or autosys was down, or even the host was late starting then how does the process know that it should start with sequence numers at 1?

   This trait is the answer.

    Ideas taken from Quickfix4J at this point, time to wrap it up.

14. case class SfSendFixMessageOutAck(correlationId: String) extends Event with Product with Serializable

    

    A case class used by the Business actor when it sends a message out.

    A case class used by the Business actor when it sends a message out. All part of AKKA io back pressure. Without this you risk not knowing AKKA closed down and messages were lost.

    correlationId

    Allows you to have a unique value which you track as you send a message out and wait for the ack back

15. case class SfSequencePair(ourSeqNum: Int, theirSeqNum: Int) extends Product with Serializable

    

16. trait SfSessOutEventRouter extends AnyRef

    

    The state for this is maintained by SfSocketActor, anything that makes it out of the socket layer (ie message is well formed) and into the SfSessionActor has one of these attached.

    The state for this is maintained by SfSocketActor, anything that makes it out of the socket layer (ie message is well formed) and into the SfSessionActor has one of these attached. It IS immutable so we do not expose state. However, this means there can be race. ie the session layer wants to send a message out but the socket is already closed

17. case class SfSessOutEventRouterImpl(businessComms: BusinessCommsHandler, sfSessionActor: ActorRef, sessionId: SfSessionId, tcpActor: ActorRef, remoteHostDebugStr: String) extends SfSessOutEventRouter with Product with Serializable

    

18. abstract class SfSession extends AnyRef

    

19. class SfSessionActor extends Actor with SfSessionActorOutActions with ActorLogging

    

20. trait SfSessionActorOutActions extends AnyRef

    

    The state machone or system commands may need this subset of operations, which are broken out to each testing.

21. class SfSessionCache extends AnyRef

22. trait SfSessionConfig extends AnyRef

23. sealed trait SfSessionControlEvent extends SfSessionEvent

    

24. sealed trait SfSessionEvent extends AnyRef

    

    Created by Jonathan during November 2016.

    Created by Jonathan during November 2016. Using Early Initialisation and a trait rather than inheritance...just to see how it works

25. case class SfSessionFixMessageEvent(msg: SfMessage) extends SfSessionEvent with Product with Serializable

    

26. case class SfSessionId(beginString: String, senderCompId: String, senderSubId: Option[String] = None, senderLocationId: Option[String] = None, targetCompId: String, targetSubId: Option[String] = None, targetLocationId: Option[String] = None) extends Product with Serializable

    

27. class SfSessionImpl extends SfSession

    

    Created by Jonathan in 2016.

    Created by Jonathan in 2016.

    If you want an easy life, just use the companion object and create the session and a file based message store for the sequence numbers, with a simple session Id. If you want a more complicated life then copy the apply function to your own code and set it up yourself.

    You should set the PersistentStore asap, and, from your implementation, as you read initial values call back into the session to set the values.

28. class SfSessionLookup extends AnyRef

    

    Every socket will have an associated lookup in order to validate the header fields match one of the assocated sessions - an initiator only ever has one per lookup, whereas an acceptor will have many potential clients who can connect

30. trait SfSessionType extends AnyRef
