3. Socket network communication design and implementation------Class adapterIn addition to the object adapter mode, the adapter pattern also has a form, that is, the class adapter mode, The biggest difference between the class adapter pattern and the object adapter pattern is that the adapter and the adaptor have different relationships between the adapters and the adapter in the object adapter pattern, whereas the adapter and the

(); } An object adapter can fit multiple classes with a suitable fit. You only need to pass different matching classes in the adapter construction method. With flexibility. Advantages of class Adapters: 1, because the adapter class is a subclass of the adapter class, it is possible to replace some adapters in the adaptor class to make the adapter more flexible. Disadvantages of class Adapters: 1, for Java, C # and other languages that do

requirements are inconsistent. Decouple the target class and the adapter class and reuse the existing adaptor class by introducing an adaptor class without modifying the original code. An object adapter can fit multiple different adapter classes to the same target, that is, the same adapter can fit the adaptor class and its subclasses to the target interface. Di

After the URL rewrite, the problem that is often encountered is that the postback destination address in the page is not the address that the client requested, but the address after the URL rewrite. For example, rewrite in one of the previous articles: When the user requests "/USER/JEFFZ", the code appearing on the page is The intent of this line of code is so obvious that it modifies the form's action to window.location (the path in the browser's address bar) so that when the page is p

Dirtailingadaptor Takes a directory path and an adaptor name as Mandatoryparameters; Repeatedly scans that directory and all subdirectories, and Startsthe indicated adaptor running on each file. Since the Dirtailingadaptor doesnot, itself, emit data, the datatype parameter is applied to the newly-spawnedadaptors. Note If you try the this in

After Windows 7 is installed, When you enable the AHCI function of the SATA hard disk in the BIOS, the system will fail to start. The system will recover to normal only after you change to the IDE (ATA) mode. If Windows is installed in IDE mode, you need to reinstall the system to change the hard disk to AHCI mode in BIOS. This allows many users to reload data.I. Introduction to AHCI AHCI (Serial ATA Advanc

nowadays, disk interfaces are mainly divided into two types: IDE (integrated drive electronics) and SCSI (small computer system interface ). They each have some differentiation or evolution, so the technical terms on disk interfaces are more and more complicated. Of course, the disk interface also has other technologies, such as optical fiber technology and familiar USB. The following describes the IDE technology. IDE is developed as a simple and cheap interface for PC. It places the hardware co

I. Category of disks Disks can be divided into ATA (IDE), SATA, SCSI, SAS, and FC disks by interface type. According to the disk chip composition, it is divided into SSD and HDD. Because the mechanical hard disk is still the mainstream configuration, we call SAS, FC and SATA both refer to the mechanical hard disk. The following is a brief introduction to Baidu Encyclopedia: ATA,The full name is AdvancedTech

transmission is very efficient, but due to physical reasons on the line, the transmission frequency cannot be too high, so the actual transmission speed is not proportional to the degree of parallelism, or even worse. (2) The serial interface refers to the serial transmission interface, which is also 0 ~ 9 10 digits. If one transmission line is used, it must be transmitted for 10 times and the Hong Kong virtual host can be used.Theoretically, the serial transmission efficiency is not high, but

1 ). Figure 1. Storage stack explored in this article Storage Architecture Attaching storage to the platform is the key to the overall Storage Architecture. The three common architectures cover the vast majority of models: ○ Direct-attached storage (DAS) ○ Storage area network (SAN) ○ Network-attached storage (NAS) Of course, Linux supports all three models and develops through changes that occur along with these models. Figure 2 illustrates these models, focusing on file systems and st

Efficiency source 7200.10 HDD read-only, ATA error handlingToday a 7200.10 data recovery, model number: ST380215A; The firmware version number is:The 3.AAC;SN number is: 9qz1hp9l. After the drive is connected to the terminal, the status displayed is "Busy". The information displayed under the instruction is: The processing of this situation, must be read-only error before the end of the hard disk detection, back to the T-level mode, can do

data. Near-end is the new storage area in recent years, its products are mainly serial ATA (Serial ATA, abbreviation is SATA), apply to the bulk storage of non-critical data, the purpose is to replace the data backup that used to use tape previously. The biggest advantage of Fibre Channel storage devices is the speed of transmission, but his price is very high, maintenance is relatively troublesome, and S

Nowadays, Sata hard disks are becoming more and more popular. The latest purchased or assembled computers are basically installed with a new generation of SATA hard disks. Because most of the initial BIOS settings are "Ide mode", Windows XP and Vista systems are installed, there is no "ahci mode" for running to maximize performance ". Is your system running in the "ahci mode "? How do I enable "ahci mode "? It is easy to figure out whether to "run in ahci mode": first, the motherboard BIOS is se

If the module is normal, but more bad, you can start from level 02 automatic calibration (self-test). Risk: ATA module will be lost, (K8k9k10 will also lose the app module) after running, to write back the original disk ATA firmware and app module. If the bad way is not much, you can start the calibration from Age26 or Age30, Age31, and not destroy the ATA Run

I. Overview　Concept　　　　In fact, to give a life example, adapter mode can be analogous to adapters, such as Typec and USB adaptor, the original can only be connected to Typec interface, expand to be able to connect to ordinary USB; Here the adaptor on the one hand need to check on the Typec, on the one hand need as a USB jack.If you want to cite a Java example, take a look at the JDBC Chapter!
