Class SpringWorkflowWorker

java.lang.Object
  com.amazonaws.services.simpleworkflow.flow.spring.SpringWorkflowWorker

All Implemented Interfaces:

Suspendable, SuspendableWorker, WorkerBase, WorkerLifecycle, org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.SmartLifecycle

public class SpringWorkflowWorker
extends Object
implements WorkerBase, org.springframework.context.SmartLifecycle

To be used with Spring. Assumes that injected implementation bean has "workflow" scope. Otherwise the same object instance will be reused for multiple decisions which is guaranteed to break replay if any instance fields are used.
