Method Detail

eventProduced

Iterable<WindowEvent> eventProduced(EventPhaseContext context,
                                    WindowEvent producedEvent,
                                    WindowEvent sourceEvent)

Context call back when an event is produced. The session argument gives to the context the capability to queue events in response of the produced event or to interrupt the phase by returning a null value. It has also access to the full history of distributed events in order to provide advanced implementation of event cycle detection.

The method can translate produced event to event to consume by returning an serie of events. When the context wants to interrupt the phase it should return the null value instead of an iterable.

During the invocation of this method, any error thrown will be propagated to the portlet controller invoker.

Parameters:

context - the session

producedEvent - the produced event

sourceEvent - the source event

Returns:

a sequence of event to consume

eventConsumed

void eventConsumed(EventPhaseContext context,
                   WindowEvent consumedEvent,
                   org.gatein.pc.api.invocation.response.PortletInvocationResponse consumerResponse)

Context call back when an event is consumed by a portlet. The session argument only provides querying capabilities and it is not possible to queue event or interrupt the session.

During the invocation of this method, any runtime exception thrown will be ignored by the controller.

During the invocation of this method, any error thrown will be propagated to the portlet controller invoker.

Parameters:

context - the session

consumedEvent - the consumed event

consumerResponse - the consumer response

eventFailed

void eventFailed(EventPhaseContext context,
                 WindowEvent failedEvent,
                 Throwable throwable)

Context call back when an event failed to be delivered because the invoker threw an exception. The session argument only provides querying capabilities and it is not possible to queue event or interrupt the session.

During the invocation of this method, any runtime exception thrown will be ignored by the controller.

During the invocation of this method, any error thrown will be propagated to the portlet controller invoker.

Parameters:

context - the session

failedEvent - the failed event

throwable - the throwable

eventDiscarded

void eventDiscarded(EventPhaseContext context,
                    WindowEvent discardedEvent,
                    int cause)

Context call back when an event is discarded by the controller for a specific reason. The session argument only provides querying capabilities and it is not possible to queue event or interrupt the session.

The cause value is an integer among the constants

• CONSUMED_EVENT_FLOODED
• EVENT_CONSUMER_INFO_NOT_AVAILABLE
• EVENT_CONSUMER_NOT_AVAILABLE
• EVENT_PRODUCER_INFO_NOT_AVAILABLE
• EVENT_PRODUCER_NOT_AVAILABLE
• PORTLET_DOES_NOT_CONSUME_EVENT
• PRODUCED_EVENT_FLOODED

During the invocation of this method, any runtime exception thrown will be ignored by the controller.

During the invocation of this method, any error thrown will be propagated to the portlet controller invoker.

Parameters:

context - the session

discardedEvent - the discarded event

cause - the cause
