Disruptor.NET示例

Question

我正在尝试学习如何使用Disruptor.NET消息框架,我找不到任何实际的例子.有很多文章都有关于它是如何工作的图片,但我找不到任何实际的内容,并向您展示如何实现这些方法.什么是一个例子？

Answer 1

感到沮丧的是,我无法为Disruptor-net找到一个可行的"Hello World",在我找到一个工作之前,我蹒跚学步 - 见下文.希望它是相当不言自明的.这些Console.WriteLine行很方便用于查看事物的运行方式 - 例如,RingBuffer在启动时创建每个条目实例(这是有意义的).

希望这有助于任何寻求.NET上的Disruptor帮助的人.

namespace DisruptorTest
{
    public sealed class ValueEntry
    {
        public long Value { get; set; }

        public ValueEntry()
        {
            Console.WriteLine("New ValueEntry created");
        }
    }

    public class ValueAdditionHandler : IEventHandler<ValueEntry>
    {
        public void OnNext(ValueEntry data, long sequence, bool endOfBatch)
        {
            Console.WriteLine("Event handled: Value = {0} (processed event {1}", data.Value, sequence);
        }
    }

    class Program
    {
        private static readonly Random _random = new Random();
        private static readonly int _ringSize = 16;  // Must be multiple of 2

        static void Main(string[] args)
        {
            var disruptor = new Disruptor.Dsl.Disruptor<ValueEntry>(() => new ValueEntry(), _ringSize, TaskScheduler.Default);

            disruptor.HandleEventsWith(new ValueAdditionHandler());

            var ringBuffer = disruptor.Start();

            while (true)
            {
                long sequenceNo = ringBuffer.Next();

                ValueEntry entry = ringBuffer[sequenceNo];

                entry.Value = _random.Next();

                ringBuffer.Publish(sequenceNo);

                Console.WriteLine("Published entry {0}, value {1}", sequenceNo, entry.Value);

                Thread.Sleep(250);
            }
        }
    }
