Quartz.Net触发事件 [英] Quartz.Net trigger event

问题描述

我有自己的 ITrigger .基本上，如下所示:

I have my own ITrigger. Basically, it looks like the below:

public interface ITrigger : IDisposable
{
    /// <summary>
    /// Occurs when an input has been trigger.
    /// </summary>
    event InputTriggedEventHandler InputTrigged;
    /// <summary>
    /// Starts the trigger.
    /// </summary>
    /// <param name="trigger">The data about the trigger to start.</param>
    void Init(Trigger trigger);
}

此接口的一种实现是 FileCreatedTrigger ，当创建文件时会触发该事件.

One implementation of this interface is a FileCreatedTrigger which fires the event when a file is created.

我想要另一个实现，可以将 Trigger 设置为以特定间隔触发(非常类似于Windows Task Scheduler).因此，我查看了 Quartz.Net ，这正是我想要的.

I want another implementation where I can set the Trigger to fire at a certain interval (much like the Windows Task Scheduler). So, I looked at the Quartz.Net and it's pretty much what I want.

问题是如何从 IJob 触发InputTrigged事件??这是Quartz所使用的.IJob仅实现execute，而execute不能调用父级(在本例中为 ITrigger ，因为它不知道这是哪个实例.

The question is How do I get the InputTrigged event to fire from an IJob? which is what Quartz uses. The IJob only implements execute which cannot call the parent (which is in this case the ITrigger as it does not know which instance this is.

希望我能说清楚.我希望能够在使用 Quartz.Net 时保留我的界面 ITrigger ，它具有另一种如何触发的实现.

Hope I made myself clear. I want to be able to keep my interface ITrigger while using Quartz.Net which has another implementation of how to trigger.

推荐答案

我最终要做的是使用guid作为键来保持对ScheduleTriggers的静态引用.然后将guid传递到jobdetail，该jobdetail使用它来查找ScheduleTrigger并引发事件.不漂亮，但能完成工作:

What I ended up doing was keeping a static reference to the ScheduleTriggers with guid as key. The guid is then passed to the jobdetail which uses it to find the ScheduleTrigger and raises the event. Not pretty, but does the job:

public class ScheduleTrigger : BaseTrigger
    {
        Guid name = Guid.NewGuid();
        static Dictionary<Guid, ScheduleTrigger> triggers = new Dictionary<Guid, ScheduleTrigger>();
        public static Dictionary<Guid, ScheduleTrigger> Triggers
        {
            get
            {
                return triggers;
            }
        }
        public void Init(Trigger triggerParam)
        {
           ....
           JobDetail jobDetail = new JobDetail(name.ToString(), Type.GetType(schedTrig.JobType.JobClassName));
           Triggers.Add(name, this);
        }
        public void Dispose()
        {
            if (Triggers.ContainsKey(name))
            {
                triggers.Remove(name);
            }
            base.Dispose();
        }

        internal void RaiseEvent()
        {
            base.OnInputTrigged(string.Empty);
        }
   }

发起活动非常简单

   EventRaiserJob : IJob
   {
       public void Execute(JobExecutionContext context)
       {
           Guid name = new Guid(context.JobDetail.Name);
           ScheduleTrigger.Triggers[name].RaiseEvent();
       }
   }
