void addEventProducer (MultiThreadedEventSourceProducer *producer)
 Adds a producer to this event source. This object takes ownership of the producer parameter and will delete it upon destruction. If this event source is enabled, the producer is started right away. Otherwise it will be started when this event source is enabled again. More...

 Constructor. More...
 
void run ()
 In a continuous loop, the source will wait for new events, and post them to the scheduler whenever they occur. All exceptions from underlying methods will be cought and logged at this level. This method is blocking.
