All Implemented Interfaces:

Step

public class OutputStep
extends Object
implements Step

Step that invokes output handler with committed events and replay flag during replay. A tracking poller is used to store the index of the last event passed to the handler. A second poller is used to also pass replayed events to the output handler. Using a CommittedEventPoller as tracking poller guarantees that only committed events are passed to the handler.
