Method Detail

eventProduced

public void eventProduced(EventPhaseContext context,
                          PortletWindowEvent producedEvent,
                          PortletWindowEvent sourceEvent)

Description copied from interface: EventControllerContext

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 session. It has also access to the full history of distributed events in order to provide advanced implementation of event cycle detection.

During the invocation of this method, any runtime exception thrown will signal a failure and the produced event will be discarded although the event distribution will continue.

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

Specified by:

eventProduced in interface EventControllerContext

Parameters:

context - the session

producedEvent - the produced event

sourceEvent - the source event

eventConsumed

public void eventConsumed(EventPhaseContext context,
                          PortletWindowEvent consumedEvent,
                          PortletInvocationResponse consumerResponse)

Description copied from interface: EventControllerContext

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.

Specified by:

eventConsumed in interface EventControllerContext

Parameters:

context - the session

consumedEvent - the consumed event

consumerResponse - the consumer response

eventFailed

public void eventFailed(EventPhaseContext context,
                        PortletWindowEvent consumedEvent,
                        java.lang.Throwable throwable)

Description copied from interface: EventControllerContext

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.

Specified by:

eventFailed in interface EventControllerContext

Parameters:

context - the session

consumedEvent - the failed event

throwable - the throwable

eventDiscarded

public void eventDiscarded(EventPhaseContext context,
                           PortletWindowEvent discardedEvent,
                           int cause)

Description copied from interface: EventControllerContext

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

• EventControllerContext.CONSUMED_EVENT_FLOODED
• EventControllerContext.EVENT_CONSUMER_INFO_NOT_AVAILABLE
• EventControllerContext.EVENT_CONSUMER_NOT_AVAILABLE
• EventControllerContext.EVENT_PRODUCER_INFO_NOT_AVAILABLE
• EventControllerContext.EVENT_PRODUCER_NOT_AVAILABLE
• EventControllerContext.PORTLET_DOES_NOT_CONSUME_EVENT
• EventControllerContext.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.

Specified by:

eventDiscarded in interface EventControllerContext

Parameters:

context - the session

discardedEvent - the discarded event

cause - the cause
