octet stream

large-capacity files due to the data format conversion, slower, inefficient.The so-called low-level I/O function is input and output in bytes, and the data format is not converted at input and output. This input and output is in binary form. Typically used to transfer a batch of bytes between memory and device. This input and output speed, high efficiency, general large-capacity file transfer with unformatted conversion of I/O. However, it is not easy to use.A file

Streaming* The stream abstracts the external storage of data (usually objects ).* Streaming APIs are abstract-It provides interfaces for reading data from the storage and writing data to the storage, but does not care what the storage is-Defined in s32std. h, and the file stream defined in s32file. h· This header file is associated with Estor. Lib.* Based on two key concepts-

The previous article describes the packaging format of the PES header, this article describes the packet format of the TS package 1.TS Baotou Format The TS Stream, the transport stream, is a further encapsulation of the PES package, the base unit is TS Packet, fixed a packet size of 188 bytes (or 204 bytes, plus 16 bytes of CRC checksum data after 188 bytes), consisting of TS Header and payload, comprisin

Byte Stream and character streamFirst look at a nasty concept:All the data in the program is transmitted or saved in a stream, and the program needs the data to read the data using the input stream, and when the program needs to save some data, it will use the output stream to complete.The input and output in the progr

Print Flow:There are two classes: The Printstream,printwriter class, the two class method is consistent, the difference is that the constructorPrintStream: Construction Method: Receive file type, receive string file name, receive byte output stream (OutputStream)Pringwriter: Construction Method: Receive file type, receive string file name, receive byte output stream (OutputStream), receive character output

The byte stream is very similar to the use of a character stream, but is there any other difference between the two in terms of manipulating the code?In fact, the byte stream in the operation itself does not use the buffer (memory), the file itself is directly manipulated, and the character stream is used in the operat

Java stream files are usually composed of a series of bytes or characters, the sequence of bytes that make up a file is called a byte stream, and the sequence of characters that make up a file is called a character stream. In Java, the direction of the stream can be divided into input and output streams. The input

2017-11-05 20:15:28 Sequenceinputstream SequenceinputStream:SequenceInputStreamRepresents a logical concatenation of other input streams. It starts with an ordered collection of input streams and reads from the first input stream until the end of the file is reached, then reads from the second input stream, and so on, until the end of the file containing the last input

Random access Flow, using mark (Mark) to mark the location of the stream, contains two methods of tell and seek; Tell, which is the return stream Mark's location, contains G and P two versions. g denotes get, refers to the input stream; P means put, the output stream; Seek is a jump to the position indicated by the

Java input/output stream (3): java input/output stream 8. bytes stream Writer/Reader In Java, the character adopts the Unicode standard. A character is a 16-bit character, that is, a character is expressed in two bytes. To this end, JAVA introduces Stream processing characters. 1. Reader abstract class The abstract cl

In the previous section, we mentioned that the main difference between stream and list is the lazy evaluation feature of stream. We also discussed that when dealing with large array datasets, the stream can move the data elements into memory one at a time and can be processed on an elemental basis. This makes me think of our common data-search reads: A large amou

Disclaimer: This post is illustrated with the example of closing the output stream in the socket.To facilitate the explanation, we put dataoutputstream dout = new DataOutputStream (New Bufferedoutputstream (Mysocket.getoutputstream ())); The dout in the socket output stream as the endorsement. Similarly, DIN is the endorsement of the input stream.Actions that can cause dout to be closed are:1, call Dout.clo
