prototype design pattern

Design Pattern (11) Decorator pattern-Structural PatternDecorator Mode In program development, developers sometimes use inheritance to extend the functions of objects. The user's requirements are changeable, which leads to wide-range changes to the Code when inheritance is used, in fact, the extended object function is much better than inheritance by using a comb

and operations are objects, which of course includes the creation of objects, so we can encapsulate the creation of objects as a specialized class, and since the products are produced from the factory, we call this class the factory class. The design pattern used to create objects is also known as Factory mode.second, simple Factory mode2.1 Introductionconsidering a simple calculator application that requi

The first two days to write a design pattern master, today to talk about our most commonly used in engineering code design Patterns-single-case design mode, the pattern in the construction code on the incidence of almost 99.99999%, but although very common, but the use of go

In the field of software design, each design pattern is systematically named, interpreted, and evaluated as an important and reusable design in an object-oriented system. In this way, as long as we understand these design patterns, we can fully or to a large extent absorb th

interfaces and do not involve other functional interfaces. Therefore, they are a type of behavior mode. The main feature of the behavior mode is to process the communication mode between objects. It is usually to introduce the intermediary object to decouple the communication parties. In this case, the context is actually decoupled from the actual algorithm provider. Therefore, compared with the policy mode, the bridge mode requires more content and more complex structures. The main significanc

Define: define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.I. Strategy Mode The purpose of the rule mode is to encapsulate each algorithm into an independent class with a common interface for mutual replacement. The policy mode allows the algorithm to change without affecting the client. Suppose we want to design a shopping cart CAT System for e-co

Definition:Strategy Pattern defines a series of algorithms, encapsulates them one by one, and enables them to replace each other. This mode allows algorithms to change independently of customers who use it. Type: object behavior mode. Overview: Policy mode is a typical object behavior mode. It separates a series of different algorithms for processing objects and encapsulates them into classes. The emergence of policies mainly aims to solve the logic j
