abstract class Primary : ProtocolLogic<SignedTransaction>
Abstracted bilateral deal protocol participant that initiates communication/handshake.
Theres a good chance we can push at least some of this logic down into core protocol logic and helper methods etc.

Primary(progressTracker: ProgressTracker = Primary.tracker()) Abstracted bilateral deal protocol participant that initiates communication/handshake. |

abstract val notaryNode: NodeInfo |
otherParty |
abstract val otherParty: Party |
payload |
abstract val payload: Any |
progressTracker |
open 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. |
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 |
open fun call(): SignedTransaction This is where you fill out your business logic. |
computeOurSignature |
open fun computeOurSignature(partialTX: SignedTransaction): WithKey |
getCounterpartyMarker |
open fun getCounterpartyMarker(party: Party): Class<*> Return the marker Class which party has used to register the counterparty protocol that is to execute on the other side. The default implementation returns the class object of this ProtocolLogic, but any Class instance will do as long as the other side registers with it. |
getPartialTransaction |
fun getPartialTransaction(): UntrustworthyData<SignedTransaction> |
verifyPartialTransaction |
fun verifyPartialTransaction(untrustedPartialTX: UntrustworthyData<SignedTransaction>): SignedTransaction |
receive |
fun <T : Any> receive(otherParty: Party): UntrustworthyData<T> fun <T : Any> receive(otherParty: Party, receiveType: Class<T>): UntrustworthyData<T> |
send |
fun send(otherParty: Party, payload: Any): Unit |
sendAndReceive |
fun <T : Any> sendAndReceive(otherParty: Party, payload: Any): UntrustworthyData<T> fun <T : Any> sendAndReceive(otherParty: Party, payload: Any, receiveType: Class<T>): UntrustworthyData<T> |
subProtocol |
fun <R> subProtocol(subLogic: ProtocolLogic<R>, : Boolean = false): R Invokes the given subprotocol by simply passing through this ProtocolLogics reference to the ProtocolStateMachine and then calling the call method. |
track |
fun track(): <ERROR CLASS><String, <ERROR CLASS><String>>? |
tracker |
fun tracker(): ProgressTracker |
Floater |
class Floater : Primary One side of the fixing protocol for an interest rate swap, but could easily be generalised furher. |
Instigator |
class Instigator : Primary One side of the protocol for inserting a pre-agreed deal. |
