class FixingRoleDecider : ProtocolLogic<Unit>
This protocol looks at the deal and decides whether to be the Fixer or Floater role in agreeing a fixing.
It is kicked off as an activity on both participant nodes by the scheduler when its time for a fixing. If the Fixer role is chosen, then that will be initiated by the FixingSessionInitiation message sent from the other party and handled by the FixingSessionInitiationHandler.
TODO: Replace FixingSessionInitiation and FixingSessionInitiationHandler with generic session initiation logic once it exists.

class LOADING : Step |
<init> |
FixingRoleDecider(ref: StateRef, timeout: Duration, progressTracker: ProgressTracker = tracker(ref.toString())) This protocol looks at the deal and decides whether to be the Fixer or Floater role in agreeing a fixing. |
progressTracker |
val progressTracker: ProgressTracker Override this to provide a ProgressTracker. If one is provided and stepped, the framework will do something helpful with the progress reports. If this protocol is invoked as a sub-protocol of another, then the tracker will be made a child of the current step in the parent. If its null, this protocol doesnt track progress. |
ref |
val ref: StateRef |
timeout |
val timeout: Duration |
logger |
val logger: <ERROR CLASS> This is where you should log things to. |
psm |
lateinit var psm: ProtocolStateMachine<*> Reference to the Fiber instance that is the top level controller for the entire flow. |
serviceHub |
val serviceHub: ServiceHub Provides access to big, heavy classes that may be reconstructed from time to time, e.g. across restarts. It is only available once the protocol has started, which means it cannnot be accessed in the constructor. Either access this lazily or from inside call. |
call |
fun call(): Unit This is where you fill out your business logic. |
receive |
fun <T : Any> receive(topic: String, sessionIDForReceive: Long, clazz: Class<T>): UntrustworthyData<T> fun <T : Any> receive(topic: String, sessionIDForReceive: Long): UntrustworthyData<T> |
send |
fun send(topic: String, destination: Party, sessionID: Long, payload: Any): Unit |
sendAndReceive |
fun <T : Any> sendAndReceive(topic: String, destination: Party, sessionIDForSend: Long, sessionIDForReceive: Long, payload: Any): UntrustworthyData<T> |
subProtocol |
fun <R> subProtocol(subLogic: ProtocolLogic<R>): R Invokes the given subprotocol by simply passing through this ProtocolLogics reference to the ProtocolStateMachine and then calling the call method. |
tracker |
fun tracker(ref: String): ProgressTracker |
