public interface PostProcessHandler
Contract for a client application callback that is invoked after execution of a job request executable.
A client application specfies a post-process callback class by setting the POST_PROCESS
system property, via either metadata or at request submission. The callback class may also implement the Cancellable
interface. The class must provide an empty constructor.
The class object is instantiated at the start of request execution. The postProceess
method will be called when the request has transitioned to COMPLETED
state.
The Enterprise Scheduler creates a new instance of the callback class each time a submitted job request is executed. As such, the job implementation should not rely on class static or instance member variables for maintaining state.

state. It must eventually return control to the caller and indicate how subsequent request processing should proceed.
This method is called only once for a given request. For example, it is not called each time a failed request is retried, or when request execution is paused to allow sub-requests to execute.
context
- the execution context associated with this requestparameters
- the request parameters associated with this requestHandlerAction
whose associated status value indicates the status of this callout. The result will be used to determine how request processing will proceed. Any action other than those listed below is not supported and will cause the request to transition to WARNING
state.
PROCEED
to inform Scheduler that request post-processing completed successfully. The request will transition to SUCCEEDED
state or WARNING
state depending on the status of the request prior to invoking the post-processor.WARN
to inform Scheduler that request post-processing resulted in a warning. The request will transition to WARNING
state.DELAY
to inform Scheduler to postpone request processing by the quantum of time specified by the REPROCESS_DELAY
property. The request remains in COMPLETED
state during the delay.SYSTEM_ERROR
to inform the Scheduler that the handler has experienced an error. The request will transition to WARNING
state.BIZ_ERROR
to inform the Scheduler that the handler has experienced a business error. The request will transition to to WARNING
state.State
