public interface CompletionCallback
A completion callback is invoked when the whole request processing is over, i.e. once a response for the request has been processed and sent back to the client or in when an unmapped exception or error is being propagated to the container.
|Modifier and Type||Method and Description|
A completion callback notification method that will be invoked when the request processing is finished, after a response is processed and is sent back to the client or when an unmapped throwable has been propagated to the hosting I/O container.
void onComplete(Throwable throwable)
An unmapped throwable is propagated to the hosting I/O container in case no
exception mapper has been found for
a throwable indicating a request processing failure.
In this case a non-
null unmapped throwable instance is passed to the method.
Note that the throwable instance represents the actual unmapped exception thrown
during the request processing, before it has been wrapped into an I/O container-specific
exception that was used to propagate the throwable to the hosting I/O container.
null, if the request processing has completed with a response that has been sent to the client. In case the request processing resulted in an unmapped exception or error that has been propagated to the hosting I/O container, this parameter contains the unmapped exception instance.
