Constructor Detail

AbstractEventSelectorProcessor

public AbstractEventSelectorProcessor(EventSelector eventSelector,
                                      SessionService sessionService)

Method Detail

setMaxSessionTime

public void setMaxSessionTime(long maxSessionTime)

setPersistResponse

public void setPersistResponse(boolean persistResponse)

Parameters:

persistResponse - true to persist the entire response including the data or false just to persist the response message

processEventImpl

protected abstract EventProcessorResponse processEventImpl(Event event)
                                                    throws Exception

Throws:

Exception

toJSON

protected String toJSON(Object obj)

getPersistableResponse

protected Object getPersistableResponse(EventProcessorResponse response)

getSessionData

protected com.mongodb.DBObject getSessionData(String sessionId)

Returns:

the data associated with the session or null if there was none

processEvent

public EventResult processEvent(Event event)
                         throws Exception

Description copied from class: AbstractEventProcessor

Process an event.

NOTE: All errors are treated as terminal i.e. there will be no follow-up events published. The event and result services are provided to allow event processing to be aware of previous and future work. If the service is used to modify queues, the results could be unexpected e.g. clearing the queue will not always mean that no more events will be processed.

Timing: Where required, implementations can manually control the times recorded for event processing.

Specified by:

processEvent in class AbstractEventProcessor

Parameters:

event - the event (along with associated data)

Returns:

the result of the process (includes errors and next events)

Throws:

Exception
