TheSeparation of Concerns(SoC) principle suggests breaking a system into smaller parts depending on its concerns. A “concern” in that meaning implies a distinctive feature of a system. 关注点分离 (SoC) 原则建议根据系统
SOLID stands for: In this article, you will be introduced to each principle individually to understand how SOLID can help make you a better developer. Single-Responsibility Principle Single-responsibility Principle (SRP) states: A class should have one and only one reason ...
The Solid::Output is a Solid::Result, meaning it has all the features of the Solid::Result. The main difference is that it only accepts keyword arguments as a value, which applies to the and_then: The called methods must receive keyword arguments, and the dependency injection will be perf...
Besides the parameters selection, an efficient implementation of the MLP classifier via fast array programming increases the defect classification performance. The feature vector x is transformed into an N× M (number of features × number of training examples) matrix, which, as a result, allows th...
N|Solid 5.x is delivered bundled with either aNode.js v18.x Hydrogen LTSorNode.js v20.x Iron LTSruntime. All N|Solid features are additive, meaning any application that runs on Node.js will also work with N|Solid. To verify the version of Node.js you have bundled in N|Solid, usen...
A general polyhedron may be multiply connected, meaning that it is topologically equivalent to a solid torus or some other higher genus solid; it may also have cavities, meaning that its boundary may have more than one connected component. We do assume, however, that at every point on the ...
In this article, we’ve taken a deep dive into the SOLID principles of object-oriented design. We started with a quick bit of SOLID history and the reasons these principles exist. Letter by letter, we’ve broken down the meaning of each principle with a quick code example that violates it...
This assumes that the module has been given a well-defined, stable description (the interface in the sense of information hiding) There have been debates about the meaning of this simple definition and its implication on the usage of Object-Oriented Programming (OOP) in the real world. ...
As I’ve already mentioned, BDD is a much wider concept which is especially handy for writing functional/acceptance tests with requirements defined upfront, (often) in a non technical form. An alternative test division syntax (with very similar meaning for the sections) is arrange-act-assert of...
Today, almost all new laptops and desktop computers use SSDs for non-volatile data storage (meaning data stored persistently that doesn’t disappear when a device is turned off, like RAM). SSDs offer extremely fast data storage and retrieval, and they’re smaller and lighter than HDDs, givin...
