public interface AsyncCancellable
When a job request is cancelled, Enterprise Scheduler determines if the client class implements the AsyncCancellable
interface, and if so, calls the cancel
method to notify the client class of the request cancellation.
Important: This interface differs from the normal Cancellable
interface in that the cancel
method has a RequestExecutionContext
parameter. This is because the physical Java object on which ESS calls execute
may not be the same object on which ESS calls cancel
due to restarts (i.e. the asynchronous job may have started, the server restarted, and then the job cancelled). The provided context
allows the client to correlate the job to be cancelled with whatever agent is running the actual job.
The client is responsible for stopping that agent and then calling onCancel
using the AsyncHelper
or by directly invoking the AsyncRequestBeanRemote
