Example 1 with BEFORE_NEXT

use of org.mule.runtime.api.notification.PolicyNotification.BEFORE_NEXT in project mule by mulesoft.

the class PolicyNextActionMessageProcessor method apply.

@Override
public Publisher<CoreEvent> apply(Publisher<CoreEvent> publisher) {
    return from(publisher).doOnNext(coreEvent -> logExecuteNextEvent("Before execute-next", coreEvent.getContext(), coreEvent.getMessage(), this.muleContext.getConfiguration().getId())).flatMap(event -> {
        Processor nextOperation = policyStateHandler.retrieveNextOperation(event.getContext().getCorrelationId());
        if (nextOperation == null) {
            return error(new MuleRuntimeException(createStaticMessage("There's no next operation configured for event context id " + event.getContext().getCorrelationId())));
        }
        popBeforeNextFlowFlowStackElement().accept(event);
        notificationHelper.notification(BEFORE_NEXT).accept(event);
        return from(processWithChildContext(event, nextOperation, ofNullable(getLocation()))).doOnSuccessOrError(notificationHelper.successOrErrorNotification(AFTER_NEXT).andThen((ev, t) -> pushAfterNextFlowStackElement().accept(event))).onErrorResume(MessagingException.class, t -> {

            policyStateHandler.getLatestState(policyStateId).ifPresent(latestStateEvent -> t.setProcessedEvent(policyEventConverter.createEvent((PrivilegedEvent) t.getEvent(), (PrivilegedEvent) latestStateEvent)));
            // Given we've used child context to ensure AFTER_NEXT notifications are fired at exactly the right time we need
            // to propagate the error to parent context manually.
            ((BaseEventContext) event.getContext()).error(resolveMessagingException(t.getFailingComponent(), muleContext).apply(t));
            return empty();
