WorkflowAction

Conforming types represent an action that advances a workflow. When applied, an action emits the next state and / or output for the workflow.

Methods

apply(toState:)

Applies this action to a given state of the workflow, optionally returning an output event.

• Parameter state: The current state of the workflow. The state is passed as an inout param, allowing actions to modify state during application.

• Returns: An optional output event for the workflow. If an output event is returned, it will be passed up the workflow hierarchy to this workflow’s parent.
