Annotation Type StartTask

@Target(value=METHOD)
@Retention(value=RUNTIME)
@Documented
public @interface StartTask

Marks a method as causing jBPM task to be started. The jBPM ContextInstance is associated with the BUSINESS_PROCESS scope and the TaskInstance is associated with a new conversation.

Note that both BeginTask and StartTask have effect before invocation of the intercepted method in that they are both about setting up appropriate ContextInstance for the current BusinessProcessContext; StartTask however, also has effect after method invocation as that is the time it actually marks the task as started.

See Also:

TaskInstance.start()
