此流接受一个目录中的文件作为输入，并将其写入另一个目录。
The flow takes a file as input from one directory, and writes it to another directory.
无论使用哪个输入文件来驱动流，输出文件的内容都是完全相同的。
The content of the output files will be identical to whichever input file is used to drive the flow.
有一点不是很重要但却很有帮助，初始打开每个应用程序时，都具有三个文件描述符，从0到2，分别表示标准输入、输出和错误流。
As a bit of helpful trivia, each application is initially opened with three file descriptors, 0 through 2, for the standard input, output, and error streams, respectively.
登录以后，创建一个目录并复制用于消息流的输入文件。
After logging on, a directory was created and an input file for a message flow was copied.
输入文件轮询和消息流可伸缩性。
要运行任一个流，请将相关输入文件的副本放在由FileInput节点读取的目录中（缺省为C:\FileExamples\FILEIN）。
To run either flow, place a copy of the relevant input file in the directory being read by the FileInput node (by default this is C:\FileExamples\FILEIN).
提供了多记录检测策略（WholeFile、FixedLength、Delimited、ParsedRecordSequence），这些策略确定消息流应该如何处理输入文件的内容。
Multiple Record Detection policies (Whole File ,Fixed Length, Delimited, Parsed Record Sequence) are supplied which determine how the input file's content should be handled by a message flow.
下面的示例显示了由名为ParsedRecordSequence _ MRMTDS . msgflow的消息流中的FileInput节点解析的输入文件的内容。
The following example shows the content of an input file which is parsed by the FileInput node in the message flow named ParsedRecordSequence_MRMTDS.msgflow.
包含File节点（无论是输入节点还是输出节点）的消息流与文件系统本身之间的交互不是事务性的。
The interactions between a message flow containing a File node (either input node or output node) and the file system itself are not transactional.
此文件用作消息流Delimited.msgflow的输入。
This file is used as input to the message flow Delimited .msgflow.
安全性配置文件中定义的安全性功能是在消息流的输入和输出/请求节点上执行的。
The security functions defined in a security profile are performed on input and output/request nodes of a message flow.
当列表中的所有文件都已完成处理时，流将返回输入目录去查找自从上次扫描以来已到达的新文件。
When all files from the list have been processed, the flow returns to the input directory to seek new files which have arrived since the previous scan.
一旦某个流实例完成其输入文件的处理，该实例立即返回线程池，并开始处理列表中的下一个输入文件。
As soon as a flow instance finishes processing its input file, it returns to the thread pool and begins work on the next input file from the list.
还需要配置消息流，指定如何从输入节点中提取身份、哪个安全性配置文件需要与输入和输出/请求节点相关联。
The message flows also need to be configured on how the identity can be extracted from input nodes, and which security profile needs to be associated with input and output/request nodes.
检查消息流是否像输入文件放在了代理的本地文件系统中一样执行。
Check that the message flow performs as if the input file had been placed in the broker's local file system.
首先，在输入方面，它将完整的XML文件读入内存，所以如果文件非常大或者需要处理XML数据流，就不能使用这个模块。
First, on input it reads the entire XML file into memory, so if the file is too big, or if you're dealing with a stream of XML data, you can't use the module.
流启动时的初始输入目录扫描将填充与输入模式匹配并等待由消息流处理的输入文件列表。
An initial scan of the input directory when the flow is started populates a list of input files that match the input pattern and are waiting to be processed by the message flow.
FileInput节点还允许指定在消息流成功完成对输入文件的处理时，应该对原始输入文件执行的操作。
The FileInput node also lets you specify what action should be carried out on the original input file when a message flow has successfully completed processing it.
对于streamfile(流文件)，输入到SUSEppc内核的完整路径。
For the stream file, enter the full path to the SUSE PPC kernel.
确保从FTP服务器删除输入文件(如下面的命令窗口所示)，并创建消息流的FileOut put节点中配置的输出文件。
Make sure that the input file is removed from the FTP server (as shown in the command window below) and that the output file is created as configured in the message flow's FileOutput node.
FileInput节点允许流开发人员指定在消息流未能成功处理输入文件时应该采取的操作。
The FileInput node allows flow developers to specify what actions should be carried out when a message flow fails to successfully process an input file.
此文件用作消息流 WholeFile.msgflow的输入。
This file is used as input to the message flowWholeFile.msgflow.
在上面这个例子中，cat命令从它自身的标准输入处，接受了从脚本文件中传递过来的输入字符流。
In the case of the script above, the cat command was given a stream of input from our script to its standard input.
与C语言文件的输入输出相比，流运算具有很多优点。
Comparing with file of C language, it has a lot of advantages.
这个函数通常用于打开一个指定的文件使用预先定义的流：标准输入，标准输出，标准错误。
This function is typically used to open a specified file as one of the predefined streams: standard input, standard output, or standard error.
这个函数通常用于打开一个指定的文件使用预先定义的流：标准输入，标准输出，标准错误。
This function is typically used to open a specified file as one of the predefined streams: standard input, standard output, or standard error.
