SagaManager<AR, A, ARM, AM> class abstract interface

Coordinates saga reactions and action publishing.

A saga manager computes actions from action results, then delegates publishing to an ActionPublisher. Metadata-aware methods preserve metadata across that boundary.

• AR: action result type
• A: action type
• ARM: action-result metadata type
• AM: action metadata type

Implemented types

• SagaContract<AR, A>
• ActionPublisher<A, ARM, AM>

Properties

Methods

computeNewActions(AR actionResult) → Stream<A>

Computes actions for actionResult without publishing them.

handle(AR actionResult) → Stream<A>

Computes and publishes actions for actionResult.

handleAll(Stream<AR> actionResults) → Stream<A>

Computes and publishes actions for all actionResults.

handleAllWithMetadata(Stream<(AR, ARM)> actionResults) → Stream<(A, AM)>

Computes and publishes actions for all metadata-bearing actionResults.

handleWithMetadata(AR actionResult, ARM metadata) → Stream<(A, AM)>

Computes and publishes actions for actionResult with metadata.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

publish(Stream<A> actions) → Stream<A>

Publishes actions.

inherited

publishWithMetadata(Stream<(A, ARM)> actions) → Stream<(A, AM)>

Publishes actions paired with action-result metadata.

inherited
