 Function<CallOutput,AbstractWorkflow.Effect.TransitionalEffect<Void>> transitionFunc)

Transition to the next step based on the result of the step call.

The Function passed to this method should receive the return type of the step call and return an AbstractWorkflow.Effect.TransitionalEffect describing the next step to transition to.

When defining the Effect, you can update the workflow state and indicate the next step to transition to. This can be another step, or a pause or end of the workflow.

When transition to another step, you can also pass an input parameter to the next step.

Parameters:

transitionInputClass - Input class for transition.

transitionFunc - Function that transform the action result to a AbstractWorkflow.Effect.TransitionalEffect

Returns:

AsyncCallStep
