StateOrchestratingComputation<C, S, E> mixin

Computes state and recursively handles saga-produced commands.

It uses a Decider and a Saga to handle commands based on the current state and produce a new state. The saga reacts to newly emitted events and recursively sends follow-up commands within the same transaction boundary.

• C: command type
• S: state type
• E: event type

Implemented types

• StateComputation<C, S, E>
• SagaContract<E, C>
