NioSelector的runLoop方法调用了singleLoop方法,后者调用了handleScheduledTasks方法,而handleScheduledTasks方法则是从taskScheduler.pollTask,然后执行task.run() 小结 TaskScheduler定义了DelayedTask,它实现了Runnable接口,它包含deadline、runnable、cancelled三个属性 TaskScheduler定义了DelayedTask类型的PriorityQueue,其comparat...
例如,核心库中有个类,名为System.Threading.Tasks.ConcurrentExclusiveSchedulerPair,其实例公开了两个TaskScheduler属性,一个叫ExclusiveScheduler,另一个叫ConcurrentScheduler。调度给ConcurrentScheduler的任务可以并发,但是要在构造ConcurrentExclusiveSchedulerPair时就要指定最大并发数(类似于前面演示的MaxConcurrencySynchronization...
慢点,注释很详细,看看这些有好处,TaskScheduler(任务调度器)不懂没关系,请继续往下看,我会介绍的,但请注意,这些标识都只是一些提议而已,在调度一个Task时,可能会、也可能不会采纳这些提议,不过有一条要注意:AttachedToParent标志,它总会得到Task采纳,因为它和TaskScheduler本身无关。 来看下这段代码: 代码语言:javas...

2.定义CancellationTokenSource变量,用于释放。通常就是调用 CancellationToken.ThrowIfCancellationRequested() ,抛出一个 “OperationCanceledException”的异常,使正在执行的Task任务停止。 3.创建Thread数组,用于存储创建出的Thread ///<summary>The threads used by the scheduler to process work.</summar...

Wake up is a complicated operation, because it requires to notify the scheduler so as it would remove the task from its waiting queue and would put it out for execution. The problem is that at the moment of wakeup the task can be anywhere. It can be still in the front queue, already...
