<init> |
Client(stx: SignedTransaction, progressTracker: ProgressTracker = Client.tracker()) A protocol to be used for obtaining a signature from a NotaryService ascertaining the transaction timestamp is correct and none of its inputs have been used in another completed transaction. |
notaryParty |
lateinit var notaryParty: Party |
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. |
topic |
val topic: String The topic to use when communicating with other parties. If more than one topic is required then use sub-protocols. Note that this is temporary until protocol sessions are properly implemented. |
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(): LegallyIdentifiable This is where you fill out your business logic. |
receive |
fun <T : Any> receive(sessionIDForReceive: Long, receiveType: Class<T>): UntrustworthyData<T> fun <T : Any> receive(sessionIDForReceive: Long): UntrustworthyData<T> |
send |
fun send(destination: Party, sessionID: Long, payload: Any): Unit |
sendAndReceive |
fun <T : Any> sendAndReceive(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. |
