人走茶凉 提交于 2021-01-23 12:33:14
问题 I'm making a wrapper to queue type, but each time I add element, I want to sort everything inside. Mostly it will be Integer . I'm not too familiar with Collections framework, is there any simple solution ? public class Round<Type> { private Queue<Type> qe; public Round(){ this.qe = new LinkedList<Type>(); } public void push(Type p){ this.qe.offer(p); //Collections.sort(this.qe); Here I want to sort this } public Type pop(){ return this.qe.poll(); } } 回答1: Are you sure that is what you want?

问题 I'm working on the logging aspect of a Laravel application, amd was planning to send the data to an SQS for retrieval at a later time. However, I would like to dispatch the job from my production server to the AWS Queue, but then have a Queue working on a separate Logging server which listens to the Queue. I understand how to setup the Queue worker to listen to the Queue, however, Laravel's Jobs are self handling. So when the worker on the Logging server retrieves the message from SQS, it

问题 As read on cplusplus.com, std::queue is implemented as follows: queues are implemented as containers adaptors, which are classes that use an encapsulated object of a specific container class as its underlying container, providing a specific set of member functions to access its elements. Elements are pushed into the "back" of the specific container and popped from its "front". The underlying container may be one of the standard container class template or some other specifically designed

问题 The program permits pushing Mapping Ints to Double and identifying the exit time from the queue. The program is not showing any error but It is not printing anything. What am I missing ? import cats.effect.{ExitCode, IO, IOApp, Timer} import fs2._ import fs2.concurrent.Queue import scala.concurrent.duration._ import scala.util.Random class Tst(q1: Queue[IO, (Double, IO[Long])])(implicit timer: Timer[IO]) { val streamData = Stream.emit(1) val scheduledStream = Stream.fixedDelay[IO](10.seconds)

Nack and reject on RabbitMQ

问题 I want to handle unsuccessful messages the consumer gets from the queue and re-queue them. Imagine I have a situation like this: P => | foo | bar | baz | => C Where foo, bar and baz are messages. If consumer reads baz but something goes wrong i can either use the basic.reject or the basic.nack ( https://www.rabbitmq.com/nack.html ). Using one of these two commands, I will pass the argument to requeue the message. The problem is the message is requeued in the same position it was before, so
