Examples of org.osgi.service.event.EventAdmin.postEvent()

org.osgi.service.event.EventAdmin.postEvent()
Initiate asynchronous, ordered delivery of an event. This method returns to the caller before delivery of the event is completed. Events are delivered in the order that they are received by this method. @param event The event to send to all listeners which subscribe to thetopic of the event. @throws SecurityException If the caller does not have{@code TopicPermission[topic,PUBLISH]} for the topic specified inthe event.

                }


                // we need async delivery, otherwise we might create a deadlock
                // as this method runs inside a synchronized block and the finishedJob
                // method as well!
                localEA.postEvent(jobEvent);
                // do not unlock if sending was successful
                unlock = false;
            } else {
                this.logger.error("Job event can't be sent as no event admin is available.");
