Task Message Boundary Events - Task processor class [VF 21.4 AgSDK]
A task processor that wants to use message boundary events must implement the ITaskProcessorWithEvents<> instead of the normal ITaskProcessor<> interface. This interface additionally determines which message boundary events can be triggered by the task processor (see section IEventPublisher<>).
Use the pre-defined NoEvents enumeration to indicate that you do not want to send either interrupting or non-interrupting events.
All other considerations (naming convention, logging, etc.) of section Task processor class for general tasks still apply.
Catching exceptions in task processor |
Note that in order to actually interrupt task processing in case of an interrupting message boundary event, the Process(…) method of the task processor must not catch the generic C# Exception class, or, if it does, must have a dedicated catch handler for the InterruptingTaskEventException and re-throw this exception. |
