Provides type conversion for the result type of a workflow activity operation.
为工作流活动操作的结果类型提供类型转换。
Each operation is an activity that might be performed.
每一个操作都是一个可以执行的活动。
This might be acceptable during short periods of heavy activity, but it should not be relied on for the steady-state operation of the server and its applications.
这在短期的大量活动时还可以接受，但要获得服务器及其应用程序的稳定操作状态，则不应依赖于此解决方案。
For example, if an operation can be modeled completely as an activity diagram there should be no reason why that operation implementation could not be generated.
举例来说，如果可以将一个操作完整地建模为活动图，那么就没有理由不能生成该操作的实现了。
You need one receive activity per operation you define in the process's interface.
您在流程接口中定义的每个操作都需要一个接收活动。
In the process editor, you can specify which operation corresponds to which receive activity.
在流程编辑器中，您可以指定哪一个操作对应于哪一个接收活动。
You could have one request perform a simple arithmetic activity and another request perform a resource intensive operation, such as reading or writing to a database.
可能有一个请求执行一个简单的算术活动，另一个请求执行一个资源密集型操作，比如数据库读写。
Because each command cannot determine the number of bytes in its respective operation, the accumulated totals and the activity bar are shown on each line.
因为这两个命令都不能确定要操作的字节数，所以每行上只显示累计的总数据量和活动条。
If something performs a single activity, then it really refers to a service operation.
如果执行单一活动，那么它实际上是指服务操作。
The registration allows a compensation operation to be invoked should the overall business activity fail.
注册使得在碰到整个业务活动失败的情况时能够调用补偿操作。
An invoke activity simply calls an operation on another service.
调用活动仅调用另一个服务的操作。
Each provided operation can have a method behavior that is an activity, interaction, state machine, or opaque behavior (code).
每一项被提供的操作都能够拥有一个方法行为：活动、交互作用、状态机、或者不透明行为(代码)。
This is an expensive operation, but at least it can be automated at the activity level.
这种操作代价会比较高，但至少在活动层可以自动执行。
In this case, if the process encounters a receive activity while it is running, the process stops and waits for the corresponding operation to be called.
在这种情况下，如果流程在运行时遇到接收活动，则流程会停止，并等待相应的操作被调用。
The first operation the process receives wins, just like a plain choice activity, and the process follows its path.
流程接收的第一个操作会首先执行，就像普通的选择活动，并且流程会按照其路径运行。
Summary: as we determined last week, UML activity diagrams document the logic of a single operation or method, a single use case, or the flow of logic of a business process.
简介：正如我们上周已确定的那样，UML活动图记录单个操作或方法的逻辑、单个用例或商业过程的逻辑流程。
In Listing 5, the process provides an in-out operation: the input message of this operation is consumed by the activity, and the output message of this operation is produced via the activity.
在清单5中，该流程提供了一个进出操作：该操作的输入消息被活动所消费，该操作的输出消息是通过活动来产生的。
The implementation of this operation was an activity in the UML service model.
这项操作的实现是UML服务模型中的一个活动。
The process contains a receive activity followed by an invoke activity, and a reply activity that is needed only if the operation offered by the process is a two-way operation.
代理流程包含一个接收活动，后面跟着一个调用活动，以及一个仅当该流程提供的操作是双向操作时才需要的应答活动。
A compensate activity lets you invoke a compensation operation for an activity or a compensation handler for a scope.
补偿活动允许您调用活动的补偿操作或范围的补偿处理程序。
This restriction is different from the conflicting receive restriction, since a request-response operation is said to be active until the corresponding reply activity has been executed.
此限制与接收冲突限制不同，因为请求-响应操作在对应的应答活动执行完成之前都处于活动状态。
This activity, shown in Figure 9, is an owned behavior of the service provider that provides the service operation.
如图9所示，该活动是提供服务操作的服务提供商所拥有的行为。
Volunteer: The Expo Center serves as the operation management center, ceremony &conference center, press center, and forum &activity center during the Expo.
志愿者：世博中心是世博会举办期间的运营指挥中心、庆典会议中心、新闻中心、论坛活动中心。
When a receive activity belongs to a request-response operation, a reply activity returns the output of the operation.
当接收活动属于请求-响应操作时，应答活动会返回操作的输出。
A test case can be an operation or a behavioral model (Interaction, State Machine, or Activity).
测试用例可以是一种操作或一种行为模型(交互图、状态机图或活动图)。
Instead, the parameters of the activity (which must correspond to the parameters of its specification operation) are referenced directly on input and output pins where needed.
相反，活动的参数节点(必须同其规范操作的参数相一致)根据需要被直接引用到输入和输出插口上。
The usage of an operation in a business process is called an activity (see the section entitled "Activities" for more details).
在业务流程中操作的使用被称为活动(欲知详情，请参阅标题为“活动”的一节)。
The second instance of the dialog occurs because an activity needs to be associated with the operation of adding the new servlet class to source control.
这个对话框需要第二次出现，是因为向源代码控制中添加新servlet类的操作需要和一个活动相关联。
Wire the new InvokeOrderValidation activity to the partner link and operation and to the input and output process variables you created above, as shown in Figure 15.
将新的InvokeOrderValidation活动连接到上面创建的合作伙伴链接和操作以及输入和输出流程变量，如图15所示。
Thus far, I've built up a core monitoring infrastructure that can systematically track application performance and measure database activity within a Servlet operation.
迄今为止，我构建了一个核心的监视基础设施，可以系统地跟踪应用程序的性能、测量servlet 操作中的数据库活动。
