ConditionedActivityGroup Sample

Artigo
09/01/2009

The sample demonstrates a travel booking application. The ConditionedActivityGroup (CAG) has two code activities: a Car activity and an Airline activity. In the SimpleCAGWorkflow constructor, a "travelNeedType" ArrayList object is populated with the types of travel bookings that are required. By commenting out one or both of the travelNeeds.Add statements, you modify the CAG behavior accordingly. Both the Car and Airline activities have their WhenConditionProperty condition populated with a CodeCondition. The Car activity executes only if the travelNeeds collection has a TravelNeeds.Car entry, and the Airline activity executes only if the travelNeeds collection has a TravelNeeds.Airline entry.

The execution of each activity removes the corresponding entry from the collection. The default UntilCondition condition specifies that the CAG should exit when no children are executing or are ready for execution (based on their WhenConditionProperty conditions). In this sample, this means that the CAG exits when the travelNeeds collection is empty.
