Class EventSenderBean

java.lang.Object
  com.espertech.esper.event.EventSenderBean

All Implemented Interfaces:

EventSender

public class EventSenderBean
extends java.lang.Object
implements EventSender

Event sender for POJO Java object events.

Allows sending only event objects of the underlying type matching the event type, or implementing the interface or extending the type. Any other event object generates an error.

Constructor Summary

EventSenderBean(EPRuntimeEventSender runtime, BeanEventType beanEventType, EventAdapterService eventAdapterService, ThreadingService threadingService)
Ctor.

Method Summary

void	route(java.lang.Object theEvent) Route the event object back to the event stream processing runtime for internal dispatching, to avoid the possibility of a stack overflow due to nested calls to sendEvent.
void	sendEvent(java.lang.Object theEvent) Processes the event object.

Constructor Detail

EventSenderBean

public EventSenderBean(EPRuntimeEventSender runtime,
                       BeanEventType beanEventType,
                       EventAdapterService eventAdapterService,
                       ThreadingService threadingService)

Ctor.

Parameters:

runtime - for processing events

beanEventType - the event type

eventAdapterService - factory for event beans and event types

threadingService - for inbound threading

Method Detail

sendEvent

public void sendEvent(java.lang.Object theEvent)

Description copied from interface: EventSender

Processes the event object.

Use the route method for sending events into the runtime from within UpdateListener code. to avoid the possibility of a stack overflow due to nested calls to sendEvent.

Specified by:

sendEvent in interface EventSender

Parameters:

theEvent - to process

route

public void route(java.lang.Object theEvent)
           throws EPException

Description copied from interface: EventSender

Route the event object back to the event stream processing runtime for internal dispatching, to avoid the possibility of a stack overflow due to nested calls to sendEvent. The route event is processed just like it was sent to the runtime, that is any active expressions seeking that event receive it. The routed event has priority over other events sent to the runtime. In a single-threaded application the routed event is processed before the next event is sent to the runtime through the EPRuntime.sendEvent method.

Specified by:

route in interface EventSender

Parameters:

theEvent - to process

Throws:

EPException - is thrown when the processing of the event lead to an error
