public RedirectEventProducer(String newEventName,
                             long delay)

Set the event to redirect to using the given time for scheduling.

Parameters:

newEventName - the new event name that inbound events will be tranformed to

Method Detail

getNextEvents

public List<Event> getNextEvents(Event event)

Description copied from interface: EventProducer

Construct a list of events to follow according the some scenario of business logic.

Implementations use the contextual data available to determine the next course of action. However, the no-op (empty list return) should be determined as quickly and cheaply as possible.

NB: Implementations must ensure that an adequate termination condition exists and return an empty list. If not, an infinite loop of events can ensue.

Parameters:

event - the event that triggered this choice

Returns:

a list of events to publish (never null) or an empty list if the scenario cannot continue
