Detailed Description

An event:EventSourceTerm that collects events from a list of event sources.

CompositeEventSource is an event:EventSourceTerm that collects events from a list of event sources. When used in an event:WaitForEvent action it will return the first event generated by any of its sources.

CompositeEventSource allows a dynamically-created list of sources to be used with event:WaitForEvent. Events returned from this source will contain the event:EventSource that originally generated the event, and not the CompositeEventSource itself.

Important: If the list of sources is changed while executing event:WaitForEvent then the behaviour is undefined.

Syntax

CompositeEventSource EventHandling.CompositeEventSource(ListTerm eventSources);

Examples

// Local Declarations
EventHandling.EventSource EventSource1;
List<EventHandling.EventSource> List1;
Integer Variable1;
EventHandling.Event Event1;
Boolean Boolean1;
 
// Flow
List1 = ListCreate(EventHandling.EventSource, { EventHandling.MonitorChangeEventSource(Variable1), EventHandling.TimerExpiredEventSource(10000)});
EventSource1 = EventHandling.CompositeEventSource(List1);

    lane
    {
        EventHandling.WaitForEvent({EventSource1}, Event1);
        Boolean1 = EventHandling.IsMonitorChangeEvent(Event1);
    }
    lane
    {
        EventHandling.Sleep(3000);
        Variable1 = 100;
    }
}
