Constructors

<init> Client(wtx: WireTransaction, 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

Properties

notaryNode lateinit var notaryNode: NodeInfo
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.

Inherited Properties

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

Functions

call fun call(): LegallyIdentifiable

This is where you fill out your business logic.
