asio interface

Must the subclass of the interface implement all the methods of the interface?Must the subclass of the interface implement all the methods in the interface? Answer: No. The reasons are as follows:If the subclass is a non-abstract class , then all methods in the interface mus

SAS (Serial Attached SCSI) is a new generation of SCSI technology, which is the same as the popular Serial ATA (SATA) hard drive. It uses Serial technology to achieve higher transmission speeds, and improve the internal space by shortening the connection line. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improv

ISP (interface segregation principle), interface isolation principleThe requirements are as follows:① The dependence of one class on another class should be established on the minimum interface.② It is better to use multiple special interfaces than to use a single total interface.③ Unrelated interfaces cannot be merged

Several customers use the same subset of the class interface, or the interfaces of the two classes are the same.Extracts the same subset into an independent interface. Motivation: There are several ways of mutual use between classes. "Using a class" usually means that all the responsibility zones of the class are used. In another case, a group of customers only use a specific subset of the class responsib

OpenCV is an open source image processing library, and the most classic version of 1.0 provides interfaces that are C-language. Later, the opencv2.x version retains the C language interface, but provides a C + + interface, where the C interface is only for backwards compatibility, while the C + + interface is the trend

Summary Clientsshoshould not be forced to depend upon interfaces that they do not use.Users cannot be forced to rely on interfaces they do not use. In other words, it is better to use multiple dedicated interfaces than to use a single total interface.It contains two meanings:-Interface design principle: the interface design should follow the minimum interface pri

Interface (Interface) is a collection of abstract methods , and interfaces are usually declared with interface. A class inherits the abstract method of an interface by inheriting the interface.interfaces are not classes , and the way they are written is similar to classes, but they are different concepts.
