In fact, you might even remember hearing somewhere that asynchronous event handlers are processed via a queue (which is true).
事实上，您可能还了解到异步事件处理程序是通过队列进行处理的(这是正确的)。
This would typically be where we need the flow to wait for an asynchronous event to occur (which takes a fixed period of time).
这将通常是因为我们需要流等待异步事件发生(需要等待一段固定的时间)。
Signals are software interrupts that send information about an occurrence of an asynchronous event to an executing program, or process.
信号就是软件中断，可以向正在执行的程序(进程)发送有关异步事件发生的信息。
The only prerequisite to installing memcached is libevent, the asynchronous event-notification library that memcached depends upon.
libevent 是安装memcached的唯一前提条件。 它是 memcached 所依赖的异步事件通知库。
The basic pattern is to obtain the Continuation from the current request, call suspend(), and wait until your asynchronous event arrives.
其基本模式是：从当前请求获得Continuation，调用suspend()，等待异步事件的到来。
First, there is a small period of time between the update of the dispenser object in the ObjectStore and the execution of the asynchronous event handler.

More precisely, the redisplay occurs after some kind of asynchronous event related to the view, such as a keystroke, a timer completion, or a response to an HTTP request.
严格来说，“重新显示”是在某些与视图有关的异步事件之后发生的，例如，按键、定时器完成或对HTTP 请求的响应。

During the design and implementation of DAEHF, this paper studies and USES such key technologies as design reuse, thread pool, asynchronous event handling, task automation deployment.
本文在设计和实现DAEHF的过程中研究使用了设计复用、线程池、异步事件处理、任务自动部署等关键技术。
The previous discussion Outlines two basic rules invocation styles (synchronous request-response style and asynchronous event-handling style) and distinguishes stateless versus stateful processing.
前面的讨论中给出了两个基本规则调用样式(同步请求-响应样式和异步事件处理样式)并对无状态处理和有状态处理进行了区分。
Asynchronous processing allows more time for each event without tying up the requesting thread.
异步处理允许在每个事件上花更多的时间，而无需占用请求线程。
Event sequencing is a technology that requires processing multiple asynchronous requests.
事件排序是一个需要处理多重异步请求的技术。
For example, within the event handler, calculation can be performed or strings concatenated for data sent along with the asynchronous request.
例如，在事件处理程序中，可以对随异步请求一同传递的数据执行计算或字符串连接操作。
If you must take action relatively quickly after an event occurs or data changes, asynchronous messaging is by far the easier and more efficient way to accomplish this.
如果在事件发生或数据更改之后必须采取相对迅速的行动，那么异步消息传递是完成这一任务更容易和更有效的方法。
Consistent with the event model, the event source is responsible for asynchronous delivery of the event messages on a frequency that it determines.
为了与事件模型一致，事件源负责按照自己确定的频率以异步方式交付事件消息。
With asynchronous log writing, the event generating the audit record does not have to wait until the record is written to disk before returning its status.
在异步写日志的情况下，生成审计记录的事件无需等到审计记录被写到磁盘便可返回它的状态。
Consistent with the event model, the event source is responsible for asynchronous delivery of event messages on a frequency that it determines.
与事件模型一致，事件资源负责以一个它所决定的频率异步传送事件消息。
Subsequent event notification is a typical example of asynchronous interaction.
接下来的事件通知则是一个典型的异步交互示例。
With asynchronous APIs, the application polls for external events and executes relevant actions when an event arrives.
通过使用异步api，应用程序将对外部事件进行轮询并在事件发生后执行相应的操作。
When the asynchronous operation finishes or when the handled event takes place, a method gets called and executed as a reaction to the event.
在异步操作完成或者事件触发的时候，就会调用方法并作为对该事件的反应。
While "standard" process components are invoked as a result of the evaluation of business rules, an asynchronous process component is triggered by the arrival of an event or message.
尽管在评估业务规则时会调用“标准”的流程组件，但异步流程组件由一个事件或消息的到达来触发。
Event source 1 will be configured to use a synchronous emitter to send events through an EJB interface. Event source 2 will use an asynchronous emitter to post events to a JMS queue.
