它的各个类和接口为数据流提供了系统输入和输出。
Its various classes and interfaces provide for system input and output for data streams.
当在高级编辑模式下查看模型时，数据输入和输出是可见的；在基本模式下则只能看到控制流。
Data inputs and outputs are visible when the model is viewed in advanced editing mode; in basic mode only the control flow is visible.
对于这个示例，使用数据流操作符输出端的蓝色箭头定义无条件连接。
For this example, define an unconditional connection using the blue arrow on the output port of the data flow operator.
最后一个参数表示输出流，用于保持或存储所提取的数据。
The last parameter represents the output stream, which holds or stores the extracted data.
这些输入和输出可以是纯控制流链接(类似于上一部分中的模型)，也可以是类似于图5所示的数据流链接。
The inputs and outputs can be pure control-flow links as in the models in the previous section, or can be data flow links as shown in Figure 5.
解析后的数据布局被放到消息流的末端，其后紧接着被写入到名为OUT .QUEUE的输出队列的消息。
This parsed data layout was taken at the end of the flow, immediately before the message was written out to the output queue named OUT.QUEUE.
在考虑 >和 >> 时，认为它们把左边命令的输出数据流移动到右边的目标文件中，这样最容易理解。
When thinking of > and >>, it's easiest to visualize them as the flow of output data moving from the command on the left to the destination file on the right.
确认该数据流操作符的输出包括ID列和原始XML输入列。
Verify that the output of this data flow operator includes the ID column as well as the original XML input column.
然后，与 CanaryHandler 类似，它打开一个radiostream连接以及数据输入和输出流。
Then, similarly to CanaryHandler, it opens a radiostream connection and data input and output streams.
如果一个任务的输出与流中的下一个任务相比具有不同的数据类型或业务项，将使用Modeler中的映射。
A map in Modeler is used when the output of one task has a different data type or business item than the next task in the flow.
InputPortlet：从用户收集信息，并基于控制流显示输出数据。
InputPortlet: Collects input from the customer and displays output data based on the control flow.
在这种情况下，SOAPElement作为SOAP消息的一个中间格式，因此定制绑定不需要关心将原始的XML数据转换为输出流的细节。
In this case, the SOAPElement ACTS as an intermediate form of a SOAP message so that custom binders do not need to pay attention to the details of writing out the raw XML data into the output stream.
下一步，使用流实用工具，通过自定义脚本来调用Hadoop，简化输出的输入数据和位置(请参考清单10)。
Next, using the streaming utility, invoke Hadoop with the custom scripts, specifying the input data and location for output (see Listing 10).
输出消息比TCP/IP流中的原始数据短4 个字节。
The output message is four bytes shorter than the original data in the TCP/IP stream.
由于工作流使用的输入输出数据格式是XML，所以我们需要xml元素名的规格说明。
As the input and output data format that workflow USES is XML, we require a specification of the XML element names.
每个业务流程都处理一些易变数据，这些数据可用于支持流中的决策，或者用作某些流活动的输入或输出参数。
Every business process deals with some amount of variable data, that might be used for decisions within the flow or as input or output parameters of some flow activities.
为了克服这点，我们使用了流：一个流(输入流或输出流)只处理单个项的数据子集。
To overcome this, we picked the concept of streams: a stream (input or output) only deals with a subset of the data of an element.
换句话说，某个早期阶段的输出数据流应该少于输入数据流。
In other words, the output data stream of one of the initial stages should be less than the sum of its inputs.
为了减少复杂的数据流模型中出现的混乱，请显示未连接的数据输入和输出。
To reduce clutter in complex data flow models, show disconnected data inputs and outputs.
比方说，可以编写一个模块读取数据库表并输出SAX事件流。
You can for example write a module that reads a table in a database and outputs a stream of SAX events.
典型的类似流的输出方法，flush和close ，可以分别用来促使编写器将任何缓存的数据写入底层输出和关闭编写器对象。
The typical output stream-like methods, flush and close, force the writer to write any cached data to the underlying output, and close the writer object, respectively.
含有 SNA字符流 (SCS)数据的spool文件包含EBCDIC 编码的文本数据，用于打印机输出。
Spool files with SNA Character Stream (SCS) data contain printer output that is formatted as EBCDIC text data.
IOutStream-输出数据流接口。
如果调试流，可以使用顶部的Resume图标监视数据流中每个步骤的输出。
If you debug the flow, you can monitor the output of each step in the data flow using the Resume icon at the top.
在图1显示的示例流程中，有一个fork和一个join，其中有悬空控制流(白色小箭头)和数据流(灰色小箭头)输入和输出。
Figure 1 shows an example process with dangling control flow (small white arrows) and data flow (small gray arrows) inputs and outputs in a fork and a join.
解码节目数据流，并输出到电视机中。
A. program data flow, and decoding the output to the TV set.
最后一个事件将会发生于每一个控件之上,然后,一直到结束.这时,所有的控件将会输出流并且不能够再被改变.在这个事件中,任何试图访问应答流的方法将都会出现错误.这个事件主要被用来清除善后工作,比如说数据库连接,打开的文件流,事件日志,或者其他的任务等等.
At this point, all controls have been rendered to the output stream and cannot be changed. During this event any attempt to access the response stream will result in an exception being thrown.
