ObjectiveThe previous article mainly describes the file character input stream filewriter, file character output stream filereader, file byte output stream fileoutputstream, file byte input stream FileInputStream, these are common flow classes. Of course, in addition to these stream classes, Java also provides a lot of flow classes for users, this article looks at other streams.Pipe flowpipeline flow is primarily used to connect two threads of communication .

(transactions)Redis's transaction is simple, and his primary purpose is to ensure that commands in a client-initiated transaction can be executed consecutively, without inserting other client commands.Look at the following example:@Testpublic void test2Trans() { Jedis jedis = new Jedis("localhost"); long start = System.currentTimeMillis(); Transaction tx = jedis.multi(); for (int i = 0; i We call the jedis.watch(…) method to monitor the key, and if the key value changes after the ca

Piping (pipe) Piping is one of the most basic IPC mechanisms by which the pipe function opens up a buffer (called a pipe) in the kernel for communication, so the pipe in the user program looks like an open file via Read (Filedes[0]), or write (filedes[1]);int pipe (int filedes[2]);parameters : The Filedes parameter is passed to the user program in two file descriptor tables. Filedes[0] pointing to the read end of the pipe, filedes[1] pointing to the pipeWrite Endreturn value : Successfully

Abstract: high-resolution radar image display is an important part of Radar Computer simulation. It has high requirements on image fidelity and real-time performance. The use of programmable rendering pipeline technology for radar display system simulation can effectively achieve the layered model of radar images, make full use of the parallel processing capabilities of cptj and GP [J, greatly reducing the computing complexity of CPU. It can generate

the advanced first-out mechanism, that is, the write pipeline process writes to the buffer head and reads the pipeline process to read the pipe tail. The command to establish the pipe is "Mknod filename p".DD allows us to copy data from one device to another device.Compress is a UNIX data compression tool.Before implementing Exp, we can first check the size of the resulting DMP file. The following steps ca

So, decided to summarize learning under arm pipeline. The ARM7 processor uses a Class 3 pipeline to increase the speed of the processor instructi

ASP. NET Core what's in the HTTP pipeline? asp. netcorePreface It's about to end on March 13, 2016. The time is so fast. After writing the Identity series last time, the response was good, so I was planning to write an ASP. NET Core middleware series, but I encountered a lot of things in the middle. The first is NPOI porting. After the transplantation, there are still some bugs to be fixed. Then, one thing is a middleware design and development work o

Introduction to the ASP. NET Web API pipeline modelThe ASP is an independent framework and has its own set of message processing pipelines, whether in the webhost hosting environment or in the Selfhost hosting environment requests and responses are from the message pipeline, this is the way to go, this is a simple introduction of the ASP. The pipeline object mode

Pipelines are similar to the way the file reads and writes, and is an older way of communicating between processes. The use of pipelines requires the creation of a pipeline file, through which the process communicates by reading and writing the file. Pipeline files do not take up disk space. You must have information in the pipeline to read within the pipe. Other

Pipeline CommunicationWhat is a pipe? The pipeline is one-way, first-out, and he connects the output of one process with the input of another. One process (write process) writes data at the end of the pipeline, and another process (read process) reads the data from the head of the pipe.Pipeline CreationPipelines include nameless pipes and two of known pipelines,

There are already several articles for IEnumerable, this article describes how to use IEnumerable to implement ETL. ETL, an abbreviation of English extract-transform-load, is used to describe the process of extracting data from the source (Extract), transpose (Transform), loading (load) to the destination. Typically, the data collected from the original end has many problems, and the business requirements may not match the data format, so the ETL process must be implemented.ETL can be understood

All HTTP requests IHttpHandler are entered, with the IHttpHandler final processing, and IHttpModule through HttpApplication the events in th

Pipeline flow (thread traffic): The main function of pipeline flow is to be able to communicate between two threads, divided into pipeline output stream (PipedOutputStream), Pipeline input stream (PipedInputStream), If you want to do pipeline output, you have to hang the out

An overview:1. A pipe function is a function that returns a rowset (capable of making a nested table nested table or array varray), and we can query it like a physical table orassigns a value to the collection variable. 2, the pipeline function for the parallel operation, in the normal function uses the Dbms_output output information, needs to be returned to the client once the server has finished running the whole function. Suppose you need to be in

IIS 7.0 supports two pipe modes: One is the latest integrated pipeline mode provided by IIS 7.0, and the other is classic pipe mode, which is provided by previous versions of IIS. We can set the pipeline mode through the application pool, which is especially useful for IIS administrators because it allows one server to run only one mode, or two modes to run on a single server at the same time. There is a si
