In additionally, we can do this with the code that looks less verbose as if we made the same thing with native Thread objects. Three main interfaces are hidden behind the concept of executors (are placed inside java.util.concurrent package: Executor basic interface that supports only the ...

java并发编程--Executor框架 摘要: Eexecutor作为灵活且强大的异步执行框架,其支持多种不同类型的任务执行策略,提供了一种标准的方法将任务的提交过程和执行过程解耦开发,基于生产者-消费者模式,其提交任务的线程相当于生产者,执行任务的线程相当于消费者,并用Runnable来表示任务,Executor的实现还提供了对生命周期的支持...

Because there are many EventExecutors in the Group, as for which EventExecutor to return, it is still implemented by the specific implementation class. In EventExecutor, it overrides this method: @Override EventExecutor next(); The next method here returns the EventExecutor itself. ...
