Detailed Description

Stop of EventHandling

The CloseEventSource Activity stops the EventHandling of all specified Event-Sources.

Closed event sources will no more queue any events. Once closed, an event source can not be reopened. Using a closed event source e.g. in a WaitForEvent action is an error and will cause an otx:InvalidReferenceException (through the EventSourceValue term).
In case that CloseEventSource is applied to an event source which is already closed, the action will perform nothing (NOP).

Note

CAUTION — In Parallel execution, situations may occur where an event source gets closed by a CloseEventSource action while being used in a WaitForEvent action (in another parallel lane). If the WaitForEvent action has no other event sources registered, this will cause a deadlock situation. OTX authors need to avoid such situations by careful test sequence design and the usage of the MutexGroup node.

Syntax

EventHandling.CloseEventSource({EventSourceVariable[ ] source});

Examples

// Local Declarations
Integer Variable1 = 0;
EventHandling.Event Event1;
EventHandling.EventSource EventSource1;
 
// Flow
EventSource1 = EventHandling.MonitorChangeEventSource(Variable1);
Variable1 = Variable1 + 1;
EventHandling.WaitForEvent({EventSource1}, Event1);
EventHandling.CloseEventSource({EventSource1});
