Interface EventDistributionService

public interface EventDistributionService

This public interface provides methods to change the activation status of processing events. Changes to the activation status are valid for the current session only and will not be persisted. In addition, there are methods to check if wires are registered for a given publishing event. The service is functionally available if the request property Constants.FEATURE_EVENT_DISTRIBUTION_SERVICE is set in the PortletRequest The EventDistributionService interface is implemented by a PortletService. A portlet can gain access to the service implementation via JNDI lookup as outlined in the following:


boolean edServiceAvailable = false;
EventDistributionService edService = null;

try {
Context ctx = new InitialContext();
PortletServiceHome serviceHome = (PortletServiceHome) ctx.lookup("portletservice/com.ibm.portal.eventing.service.EventDistributionService");
edService = (EventDistributionService)serviceHome.getPortletService(com.ibm.portal.eventing.service.EventDistributionService.class);
edServiceAvailable = true;
}
catch(Throwable t) {
}

                     throws EventDistributionServiceException

This method returns true if the calling portlet´s given publishing event is currently wired. The knowledge of whether a publishing event is wired may be used by the owning portlet to display additional visual elements such as links which trigger an invocation of this event.

Parameters:

request - the current PortletRequest object

response - the current PortletResponse object

publishingEventName -

Returns:

true if the publishing event of the calling portlet window´s portlet definition is wired to other communication targets

Throws:

EventDistributionServiceException
