Broadcast

class Broadcast : ProtocolLogic<Unit>


Types

NOTIFYING object NOTIFYING : Step

Constructors

<init> Broadcast(date: LocalDate, progressTracker: ProgressTracker = Broadcast.tracker())

Properties

date val date: LocalDate
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. 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.

Functions

call fun call(): Unit

This is where you fill out your business logic.
