the client program should not be forced to rely on methods that they do not need to use. Its English abbreviation is ISP, English full name is interface segregation Principle. in fact, the interface separation principle means: an interface does not need to provide too much behavior, an interface should only provide an external function, should not be all operations are encapsulated in an interface. 6. Dimitri Principles (LOD) The core idea of the Dimitri principle is that one object should kno

A distributed hash (DHT) implementation algorithm, proposed by MIT in 1997, was designed to address hot spot problems in the Internet, with a similar intent to carp. The consistent hash corrects the problem caused by the simple hashing algorithm used by carp, so that distributed hashing (DHT) can be really applied in the peer-to-peer environment. The consistency hash algorithm proposes four definitions for

. For example, if you have adjusted the kernel parameters, you must run it again. /configure to make the new settings take effect. You need to re-run the configure script before using the make command to re-compile the script. There are two methods: first, run the following command: config. status -- recheck; the second is to use the command touch config. status, which updates the timestamp of the file. Note: If you want to add or delete the./configure option, you must re-enter the complete comm

Someone sitting in the middle of the fish pond has already begun to catch a hacker. We still get nothing here, a little depressed. It's almost and it's just getting started. My dad's hook ran a crucian carp, marking that the water wasn't without fish. Then the tragedy began to get connected, first, an uncle's fishing wire fell off

When he saw me, he also saw the white paper behind me: "selling as a dead mother "."What is your name ?" He stood in front of me and looked gentle.I slowly raised my head and looked straight at him: "It looks like duckweed, and there is no surname .""Duckweed? You should not be the one who is on the move. At least you should swim like a fish in the water .""Fish? The little girl has h

Demeter (or the short-cut-level) is also called the least knowledge principle (least knowledge principle or LKP). If the two classes do not communicate with each other directly, then these two classes should not have a direct interaction. If one class needs to call a method of another class, it can be forwarded by a third party. The premise of the dimit rule is that in the structure design of the class, each class should minimize the access permissions of members. The fundamental idea of the di

design depends on details, which is poor because the policy is affected by changes in details. The dependency inversion principle makes the details and policies depend on abstraction. The stability of abstraction determines the stability of the system. Iv. Interface isolation principle (ISP) Interface segregation principle: it is better to use multiple special interfaces than to use a single total interface. In other words, from the perspective of a customer class: the dependence of a class

Black fungus, grown on bamboo trees, looks like human ears, black or brown black. It is also known as black fungus, also known as wood fungus, trek chicken. Black fungus is extremely nutritious,According to historical records, it was the exclusive product of Emperors in the ancient times, containing a lot of carbohydrate, protein, iron, calcium, phosphorus, carotene,Vitamins and other nutrients, each 100 grams containing 375 mg of calcium, equivalent to 7 times of crucian

Just like a child looking at the old man, thinking that there will be endless fish as long as there is a fishing rod, like a staff looking at the boss, thinking that as long as you sit in the office, there will be a financial source.

At first, the shark continuously collided with the invisible glass every day,

object-oriented language. Beauty is a base class, and sister is a child class of beauty. As a "Love ()" method, brother accepts sister as a parameter. Therefore, this "love ()" method generally cannot accept the beauty instance. I will not turn the example of the rectangle square below. You can go to the blog address above to learn about it. 2.

. My umbrella is convenient. it sits there waiting for me. it has wheels on it so that I do not have to carry it around. I don't even have to push it because it can propel itself. sometimes, I will open the top of my umbrella to let in the sun. (Why I am using my umbrella when it is sunny outside is beyond me !) In Seattle, there are hundreds of thousands of these umbrellas in all kinds of colors. Most people call them cars. Implementation Method:1. Use the delegate separation Interface2. Use mu
