解析器向一个事件处理程序发送事件，比如元素的开始和结束，而事件处理程序则处理该信息。
The parser sends events, such as the start or end of an element, to an event handler, which processes the information.
事件处理程序如清单20所示。
reviewStartRequest事件处理程序的输入变量。
如果没有事件处理程序处理这个单击事件，它就会沿着同样的路线再返回到根元素，这时根元素默认的单击处理程序将忽略该事件。
If no event handlers processed the click, the event will travel back up the same path until it comes back to the root element, where the default click handler will ignore it.
此规定的结果是，如果某个事件处理程序实现了一个请求-响应操作，则在任何时间点，只能有一个此类事件处理程序的实例处于活动状态。
The effect of this is that if an event handler implements a request-response operation, then only one instance of such an event handler may be active at any point in time.
为了保证流程执行所有事件处理程序，此接收活动将等待最后一个事件处理程序实例发送完成通知。
To guarantee that the process executes all event handlers, this receive activity waits until the last active event handler instance sends a notification of completion.
首先，我们必须修改对所有事件处理程序的完成情况进行的检查，以反映只要有三个事件处理程序完成就足够了。
First we have to modify the check for completion of all event handlers to reflect that it is sufficient if three event handlers have finished.
简单地说，过滤器是将接收到的事件传送给另一个事件处理程序的SAX事件处理程序。
Simply put, a filter is a SAX event handler that passes the events it receives to another event handler.
将为事件处理程序的每个实例提供该事件处理程序内定义的所有进程数据和控制行为的私有副本。
A private copy of all process data and control behavior defined within an event handler is provided to each instance of an event handler.
这样，主范围内的循环和事件处理程序中的逻辑就可以控制事件处理程序的最终数目。
By doing so, the loop in the main scope and logic in the event handler controls the final number of event handler instances.
我们将在下面了解到，为了获得事件处理程序实例的已确定范围的局部变量，可以将活动的范围定义为事件处理程序的直接子项。
We'll see below that it is useful to define a scope as a direct child of an event handler in order to have scoped variables that are local to the event handler instance.
本文描述如何设计使用事件处理程序来实现取消操作的流程。
This article described how to design processes to implement the cancellation function with the event handler.
通常，应用程序可以通过多个连接端口用事件处理程序创建事件侦听程序，但是这在网络资源和维护方面花费较大。
Generally, an application can create event listeners with event handlers through multiple connection ports, but this is costly in terms of network resources and maintenance.
您将构造一个具有简单控件和事件处理程序的简式窗口，这些简单控件和事件处理程序使输入姓名和年龄，然后调用服务成为可能。
You will construct a simple form window with some simple controls and event handlers that make it possible to enter a name and age, and then invoke the service.
此调用活动将调用事件处理程序。
事件处理程序是在与其关联的范围启动时启用的。
Event handlers are enabled when the scope they are associated with starts.
安装任何一种事件处理程序都是需要技巧的，因为正在修改的元素很可能已经在其内安装了事件处理程序。
Installing event handlers of any kind can be tricky, because there's always the chance that the elements you are modifying already have event handlers installed in them.
虽然事件处理程序只处理某种单一事件，拖动处理程序却可以处理整个拖放过程。
Although an event handler handles a single event of some kind, a drag handler handles the entire drag-and-drop process.
范围可以提供错误处理程序、事件处理程序、补偿处理程序、局部变量、本地伙伴连接和本地相关集。
A scope can provide fault handlers, event handlers, a compensation handler, local variables, local partner links, and local correlation sets.
清单4显示了如何用SBLIMCIM客户机库绑定事件处理程序与事件过滤器。
Listing 4 shows how to bind an event handler to an event filter with the SBLIM CIM client library.
事件处理程序是对应特定事件的一段可执行代码或者标记。
An event handler is a piece of executable code or markup that responds to a particular event.
在事件驱动环境中，视图通过事件处理程序调用代码。
In event-driven environments, the view invokes code through event handlers.

Listing 3 shows the code snippet getting the event handler by a process instance ID.
组件的事件处理程序通常都是在调用程序阶段执行的。
The event handler for components normally executes in the invoke application phase.
