react 器模式在wikipedia中进行了解释。 ，这有点太抽象了。您能更具体地描述这种模式吗？理想情况下，使用代码片段或高级类图来描述 react 器模式的一些应用。

您可能想查看描述它的原始论文 http://www.dre.vanderbilt.edu/~schmidt/PDF/reactor-siemens.pdf

The Reactor design pattern handles service requests that are delivered concurrently to an application by one or more clients. Each service in an application may consist of serveral methods and is represented by a separate event handler that is responsible for dispatching service-specific requests. Dispatching of event handlers is performed by an initiation dispatcher, which manages the registered event handlers. Demultiplexing of service requests is performed by a synchronous event demultiplexer.
