我们假设您想编写一个启用语音的饮料选择器程序。
Let us say you want to write a voice-enabled drink selector program.
在本部分中，通过修改业务流程的调用活动，可使您的应用程序更灵活，以便它可以调用选择器，而不是指定的组件。
In this section, you make the application more flexible by modifying the invoke activity of the business process so that it calls the selector, rather than a specific component.
在本部分中，您将把选择器添加到现有应用程序中。
In this section, you add a selector to an existing application.
这包括函数选择器、数据处理程序和数据绑定。
This includes function selectors, data handlers, and data bindings.
您可以在运行时更新或修改选择器及其对应的日期范围的目标，而无需重新部署初始应用程序。
You can update or modify the destinations of a selector and their corresponding date ranges at runtime without redeploying the original application.
现在，您几乎具有了富桌面应用程序中可用的每一样东西：有日期选择器、菜单、树、滑块，窗口等等。
Today, you have nearly everything available in a rich desktop application: You have date pickers, menus, trees, sliders, windows, and more.
jms函数选择器——我们介绍过如何作为服务查看接收JMS消息的应用程序，还记得吗？
JMS Function Selector — Remember that we explained how we view the application receiving the JMS message as a service?
现有应用程序会调用静态服务实现，因此通过引入选择器可以使应用程序变得更灵活。
The existing application invokes a static service implementation, so you will make the application more flexible by introducing a selector.
本文包含这种语音应用程序的部件清单，但您首先想知道的是这个选择器的设计流以及不同的组件如何交互。
This article includes a listing of the parts of such a voice application, but first you will want to know the flow of design of this selector and how the different components interact.
然后COE将确定对应的项目团队以构建和部署不同版本的服务，这些服务版本通过中介、业务规则、选择器和动态业务组装程序进行路由。
Then the COE identifies the corresponding project teams to build and deploy different versions of services routed through mediators, business rules, selectors, and business dynamic assemblers.
随机选择器：在现实生活中，应用程序页面击中通常是随机的。
Random selector: In real life, application page hit is usually random.
如图1所示，选择器在内部保存这些详细信息，直到应用程序在选择器上调用select方法，见清单4。
Figure 1 shows that the selector internally keeps these details until the application calls a select method, as shown in Listing 4 on the selector.
当应用程序注册通道时，选择器在本机pollset结构中注册文件描述符和感兴趣的事件。
The selector then registers file descriptors and interested events into a native pollset structure when the application registers the channel.
为了简化日期录入，基于日期的字段与XMLSchemadate类型关联，处理程序提供日期选择器来输入日期。
To ease the entry of dates, the date-based fields are associated with the XML Schema date type, and the processor provides a date-picker for date entry.
正如前面提到的，当应用程序打开poll选择器时，poll选择器会创建一个本机pollset结构。
As mentioned earlier, a pollset selector creates a native pollset structure when an application opens the selector.
然后，应用程序用register调用向选择器注册通道(文件描述符)和感兴趣的操作。
The application then registers channels (file descriptors) and interested operations to the selector with a register call on the channel.
这意味着，你能在应用程序中使用所有的标准iPhone控件，如选择器(Pickers)、滑动条(Sliders)、按钮等等。
This means that you have all the standard iPhone controls available to your application, including Pickers, Sliders, Buttons, etc.
它提取了一些细节，工作方式更像ProcessServer中的JMS绑定类型，包括它的数据处理程序风格、功能选择器等等。
It abstracts some of the details away and works more like the JMS binding types in Process Server, including their data handler styles, function selectors, and so on.
选择器(selector)与Windows消息循环类似，它从不同客户机捕获各种事件并将它们分派到相应的事件处理程序。
A selector is analogous to a Windows message loop, in which the selector captures the various events from different clients and dispatches them to their respective event handlers.
然后，选择器把通道和感兴趣的操作复制到内核空间，让内核为这个应用程序执行实际的poll。
The selector then copies the channels and interested operations into the kernel space and let the kernel do the actual polling for the application.
它是所有功能于一身的的程序，提供功能全面的屏幕捕捉工具，直观的图像编辑器，颜色选择器，调色板，像素尺，量角器，十字线，甚至白板。
It is an all-in-one program that provides full-featured screen capture tool, intuitive image editor, color picker, color palette, pixel ruler, protractor, crosshair and even whiteboard.
许多应用程序与颜色选择器都，并排或在单独的标签。
Many applications with color pickers have both, side by side or in separate tabs.
需要浏览适当的程序码片段时，您可以使用程序码片段选择器，从分类的程序码片段清单中进行选择。
When you have to browse for an appropriate snippet, you can use the snippet picker, which gives you categorized lists of snippets to choose from.
需要浏览适当的程序码片段时，您可以使用程序码片段选择器，从分类的程序码片段清单中进行选择。
When you have to browse for an appropriate snippet, you can use the snippet picker, which gives you categorized lists of snippets to choose from.
