Annotation Interface Stateful

@Documented @Target(TYPE) @Retention(RUNTIME) @Inherited public @interface Stateful

Annotation that a Processor, ReportingTask, FlowAnalysisRule, ParameterProvider, or Controller Service can use to indicate that the component makes use of the StateManager. This annotation provides the user with a description of what information is being stored so that the user is able to understand what is shown to them and know what they are clearing should they choose to clear the state. Additionally, the UI will not show any state information to users if this annotation is not present.
