Stream has four types of streams:readable -readable operation.writable -writable operation.Duplex -readable writable operation.Transform -The operation is written to the data and then the result is read.All Stream objects are instances of Eventemitter. The usual events are: data-triggered when there is a read.End -triggers when there is no more data to read. Error-triggered when a fault occurs during receiv
Byte stream, character stream involves more analogy, more easily confused. Therefore, it is necessary to make a generalization about when to use a byte stream, when to use a character stream, and when to use a stream of the buffer class. To generalize them, you don't need to

There are three popular product elements: waterfall stream, dynamic stream, and medal. What I call this product is vulgar and it is easy to be abused due to its popularity. PM may choose them because they are "fashionable" and "standard" and "used by others", which is terrible. I have been tossing about the dynamic stream and the medal, but I have suffered a litt
. Net stream-use stream for file replication,. net flow
Similar to various file streams and network streams in Java,. net also has various types of streams. The main purpose of a stream is to interact with files or data sources outside the application. The base class is Stream, which is defined in the namespace System
The point to be emphasized here is:The input stream and the output stream, the difference is the out and in, is relative to the program. The input stream gets the data, and the output stream is the output data. Input is the program to get external data, the output is the program to the external transmission of data, th
Detailed description of the cin standard input stream and the cin input stream
A standard input stream is used to input data to a program from an input device (such as a keyboard. in the header file iostream. the cin, cout, and cerr objects are defined in h. cin is the input stream, and others are the output
JavaIO stream (1): basic concepts and basic concepts of javaio stream
I. input and output streams
Input stream: when the program is running, you may need to read the required data from external storage media or other programs and use the input stream.
Output stream: After a

Works [file stream and dictionary stream exercises] For s60 fp2
It's not easy. It took two weeks to complete the process. I encountered a lot of problems and solved them a little bit. However, I understood the file stream and dictionary stream. What I have not solved is:
The storage
The byte array input stream creates a byte array buffer in memory, and the data read from the input stream is saved in the byte array buffer. There are several ways to create a byte array input stream Object.The receive byte array is created as a parameter:New Bytearrayinputstream (byte [] a);Another way to create this is to receive a byte array, and two shaping
Java java.io.*; provides the relevant classes for streaming input and output of data, Io flow is an abstraction of input and output, and Java abstracts data from these different sources and targets into data streams. The benefit of unifying the input and output data as a stream is that the program does not have to be concerned with whether to read the file or the data in the network, but to treat it uniformly as an IO stream.IO
// Remember the data type that is used for output,
// For example, DOS. writeint (100); write, read: DIS. readutf () sometimes has unexpected errors, so you must always remember what data type is used for data type output reading.

Fileinputstream FCM = NUL
Reader,inputstream is used to read the contents of a resource, which can be a file or a networkFirst, there is a TXT file, the contents of the file are as followsFile F = new files ("path"); FileInputStream fis = new FileInputStream (f);//create an input stream, read the contents of F into the program to//SYSTEM.OUT.PRINTLN (Fis.read ()); byte[] B = new byte[1024];//defines an array that holds the read class tolerance int hasread = 0;//used to record
Random Access stream: The Randomaccessfile class does not belong to a stream and is a subclass of the object class.But it incorporates the functions of InputStream and OutputStream. Support for random access to files read and write.Public Randomaccessfile (String name,string mode): The first parameter is the file path, the second parameter is the mode of the action filemode: parameter specifies the access
