public CompletableFuture<DashboardConfiguration> handleRequest(@Nonnull HandlerRequest<EmptyRequestBody,EmptyMessageParameters> request, @Nonnull RestfulGateway gateway)
AbstractRestHandler
CompletableFuture
containing a the response.
Implementations may decide whether to throw RestHandlerException
s or fail the returned
CompletableFuture
with a RestHandlerException
.
Failing the future with another exception type or throwing unchecked exceptions is regarded as an
implementation error as it does not allow us to provide a meaningful HTTP status code. In this case a
HttpResponseStatus.INTERNAL_SERVER_ERROR
will be returned.
