How to measure software design quality 1The first standardMeet the functional requirements of the softwareThe design that meets the requirements of software functionality is not necessarily a good design.Good design.Readability: Software design

What is proxy mode? Composition: Abstract Role: A business method that declares a real role through an interface or abstract class. Proxy role: the implementation of abstract role, is the real role of the agent, through the real role of the business

This series of interface-oriented programming is divided into three parts: Interface-oriented programming (1)-ideological basis (released)In this article, I will give a rough introduction to interfaces and interface-oriented programming, focusing

In object-oriented design, how to deal with changes in design requirements through small changes is a matter of great concern to designers. To this end, many oo pioneers have proposed many object-oriented design principles to guide the design and

. NetProvides interfaces, which are different fromClassOrStruct. In some cases, the interface seems to be the same as the abstract class, so some people think that. NetThe abstract class can be completely replaced by interfaces. In fact, interfaces

. NET provides interfaces, which are different from class or struct type definitions. In some cases, the interface seems to be the same as the abstract class, so some people think that the. NET interface can be used to replace the abstract class

This article introduces the application examples of the application of the automatic loading class object serialization polymorphism in the object oriented in PHP, and the students who need to know can look at it. Auto Load ClassMany developers

Statement: This series of blog reference "Big Talk design mode", author Geoscience. The policy pattern defines a series of algorithms, encapsulates each algorithm, and allows them to be replaced with each other. The policy pattern makes the

1. policy mode concept policy mode each algorithm is encapsulated into an independent class with a common interface for a group of algorithms. This mode allows algorithm changes to be independent of customers who use algorithms. So as to make the

PHP design mode--strategy mode Statement: This series of blog reference "Big Talk design mode", author Geoscience. The policy pattern defines a series of algorithms, encapsulates each algorithm, and allows them to be replaced with each other. The

This article introduces the bridge (Bridge) Concepts, usage, and usage of the PatternBridging ModeFor development. Bridge Mode Concept The bridge mode is one of the constructor design patterns. Based on the minimum design principle of classes,

ArticleDirectory Source code The rule mode is the behavior mode of the object. Intended for a groupAlgorithm, Encapsulate each algorithm into an independent class with a common interface, so that they can be replaced with each other.

Schema Definition:The objects are organized in a tree structure to achieve a "partial-overall" hierarchy, which makes the client consistent with the use of individual (leaf) objects and composite objects.Design Purpose:Let the client no longer

One, single Responsibility Principe is the SRP.Benefits of a single responsibility principle:1, the complexity of the class is reduced, the realization of what responsibilities are clearly defined;2, readability increases, complexity reduces, that

1. OverviewTransforms the interface of one class into another interface that the customer wants. The adapter mode makes it possible to work together those classes that would otherwise not work together because of incompatible interfaces.2. Issues to

When to use an interface or abstract class:1, if you want to create a model, this model will be used by some closely related objects to use the abstract class. Interfaces are used if you want to create features that will be used by unrelated objects.

23 design modes (16) java visitor mode and 23 design modes 23 design patterns Article 16th: java visitor Mode Definition: encapsulate some operations that act on each element in a data structure. It can define new operations that act on these

Multi-person developmentin Java, you can separate the classes in a large project, categorize them into files, and compile them together, so that the program code will be easier to maintain. Multi-person development problem: If multiple developers

Eclipse debugging skills (Summary), eclipsedebug As a developer, it is necessary to master debugging skills in the development environment. During java programming, we often encounter various inexplicable problems. In order to detect the problem of

Design Pattern-prototype pattern (06), design pattern prototypeDefinition Prototype Pattern is a simple design mode. The prototype is Specify the kind of objects to create using a prototypical instance, and create new objects by copying this
