NET design Pattern Part II Structural model (14): Thematic summary of structural patterns

--Explore the design pattern seriesTERRYLEE,2006 year MayAbstract: The structural pattern, as the name implies, discusses the structure of classes and objects, which use inheritance to combine interfaces or implementations (class-structured patterns), or to implement new functions (object-structured patterns) by combining some objects. These structural patterns,

"Onlookers" design pattern (30)--Summary of structural design patterns (adapters, agents, decorations, appearances, bridges, combinations, and benefits)

data to be stored, a certain setting before the data into our database, I was the solution is to put the local ID is set to string type, Then through id_**, the id_ identity bit identifies which id the value belongs to and the meaning it represents. In order to achieve this, I used the adapter mode, the data passed by the other side of the package, through the adapter to the encapsulated object into the object we can store locally."Onlookers" design

pretty good:-oYour clothes are so beautiful:-o Advantages and disadvantages of the Bridge Mode: Advantages: The bridge mode provides more flexible functions than the inheritance relationship. It can use abstraction and separation to reduce coupling. When there is a new abstraction or implementation method, you only need to inherit an abstraction and inherit an implementation. Disadvantages: If you want to reabstract another type, you need to modify the abstraction. Introduc

Structural design in the interface design

The elements that construct the visual level of the interface have the obvious degree of color, the size of picture and text, and the most basic and content organization structure. Structural design refers to the process of grouping the content of the interface, designing the information and data in the interface, and making the structure of the presentation. Good structure

In the getservice function of the Servicefetcher object, first from the list of cache arrays maintained by the context, find if the index of the Servicefetcher object already

format used. The toolkit is common instead of applicable to a specific development, therefore, modifications are also made using the Toolkit in specific development. 2. If you want to change the interface form of the Toolkit, you also need to know the source code of the toolkit. 3. Changes to the toolkit may require a lot of work and may cause errors. Therefore, the interface form of the toolkit is usually not modified directly, but the incompatibility between these interfaces is converted into

Design Pattern Summary: Structural model (bottom)

In general, design patterns fall into three broad categories:Create Five types of models: Factory method mode, abstract Factory mode, singleton mode, builder mode, prototype mode.structure mode , a total of seven kinds: Adapter mode, adorner mode, proxy mode, appearance mode, bridging mode, combined mode, enjoy the meta-mode.There are 11 types of Behavioral patterns : Strategy mode, template method mode, observer mode, iteration sub-mode, responsibili

The structural design method of software engineering

The structural analysis method is developed on the basis of modularization, top-down progressive refinement and structural programming, which can be divided into two categories: one is based on the data flow of system system, and the other is designed according to the data structure of the system.5 Principles of software design:1 Divide and Conquer: the large and

design mode (vi) bridge mode bridges (structural type)1. Overview In a software system, some types, because of their own logic, have two or more dimensions that change, so how do you deal with this "multidimensional change"? How can you use object-oriented technology to make this type easily change in multiple directions without introducing additional complexity? Example 1: Imagine that if you

Design Pattern structural pattern

In the previous blog, I wrote about the Creation Mode (factory family ). Here we will introduce the structural mode. It mainly describes the meaning, advantages and disadvantages, application scenarios, and structure of each mode to understand the structural mode. The structural mode includes seven modes: adapter mode, appearance mode, proxy mode, Bridge Mode, sh
