Instigator

class Instigator<OldState : ContractState, out NewState : ContractState> : Instigator<OldState, NewState, Class<out UpgradedContract<OldState, NewState>>>

Constructors

<init> Instigator(originalState: StateAndRef<OldState>, newContractClass: Class<out UpgradedContract<OldState, NewState>>)

Inherited Properties

modification val modification: M
originalState val originalState: StateAndRef<S>
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 flow is invoked as a subflow of another, then the tracker will be made a child of the current step in the parent. If it's null, this flow doesn't track progress.

Functions

assembleTx fun assembleTx(): Pair<SignedTransaction, Iterable<CompositeKey>>

Inherited Functions

call open fun call(): StateAndRef<T>

This is where you fill out your business logic. The returned object will usually be ignored, but can be helpful if this flow is meant to be used as a subflow.
