Problems in the real world There is a socket, this socket is three mouth, but we have only two tentacles of the plug, a stupid method is to directly force the two tentacles bent, inserted into (this kind of thing I have done), there is another way is to find a conversion head.Look at the following figure is probably clear, it is obvious that the existing system is difficult to match with vendors, how to do it? Well, the adapter is handy.
Some examples of life In our daily life, for the adapter, can be said to be everywhere. For example, we usually use the notebook computer, may be the operating voltage of the laptop is 20V, but our general household electricity is 220V, this time when the computer is charged with a power adapter to the 220V of the computer to convert to 20V voltage. This power adapter
Adapter mode what is adapter Mode The adapter mode is a structural mode that allows two unmatched interfaces to work together. The adapter mode allows two unmatched classes to work collaboratively by converting one interface type to another interface type that the client expects. The
In Series 1, the RM and MPEG classes inherit the videomedia abstract class, while the videomedia class implements the imedia interface, which only provides the play () method. Ice soda is intended to provide RM, MPEG with different attributes and methods than audiomedia. For example, for Video Media, there should be a method to adjust the screen size, such as resize (). This method is not available for the imedia interface. So how does one provide the resize () method not available in the imed
experience reach a certain level, and it also means to summarize a lot of good design experience, however, it may not be the case that "no teacher can do anything", or you can say that, on the basis of level and experience, it is time for the system to learn the "mode, it is helpful to learn the experts' summary and verify your own shortcomings. This series of design patterns learning notes is actually a Learning Record for the book "Java and patterns. Adap
Design Mode note 07-adapter mode and appearance Mode1 IntroductionIn this chapter, we will carry out a task, to the extent that it is impossible to put a square into a circular hole. That sounds impossible? With the design model, it is possible. Do you still remember the decorator mode? We pack the objects and give them new responsibilities. Now, some objects are packaged for different purposes: to make their interfaces look different from what they a
One, Windows 7 hidden Features--Virtual WiFi WiFi technology has changed the use of many computer users, but over the years, in addition to the speed of the increase in coverage and increase the security, wireless technology has not been much development. Since 2002, however, Microsoft Research has been working on a virtualized WiFi adapter that receives almost all wireless signals through a single hardware. Now, this virtual WiFi technology has been
written in front of the words: See the title so long may be a little crazy, yes, I just learned this article when there are some do not understand, what is the layout of the pump? Edit each template then what is a custom adapter? Below we begin to learn the content of this article Preferred previous picture to achieve effect: Logical parsing: First of all, the above diagram is the final implementation of the effect, a bit like our contacts cont
Adapter mode An intention Transforms the interface of one class into another interface that the customer wants. The adapter mode makes it possible for those classes that would otherwise be incompatible with the interface to work together. Two motives A generic class designed for reuse, there are always special situations that make it not possible to use or complete the appropriate extensibility functions. S
Java design mode Series (vi) adapter mode The adapter mode transforms the interface of one class into another interface that the client expects, so that two classes that would otherwise not work together because of an interface mismatch can work together. Structure of the adapter mode: class's Adapter
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 solveThat is, the adapter mode makes it possible for those classes that cannot work together because the interface is incompatible.Here are two very vivid examp

Adapter data changes the implementation principle and case of the existing View, adapterview First, let's talk about the inheritance relationship of the specific class of the Adapter, as shown in Adapte serves as a bridge between AdapterView and View. The Adapter loads View (such as the data to be displayed in ListView and girdView ). The data to be displayed i
Analysis from the Bluetooth Technology: 1. Distance: many sellers on the market announced support for 20 m, 30 m, 50 m, etc. In fact, this is the distance from Bluetooth support for sellers.Is there two standard classes? 1 and class? 2, class? 1 supports a standard distance of 100 m and class2 supports a distance of 10 m. In fact, the distance is notIn the case of obstacles, class? 2 can support up to 10-20 meters, class? 1 can support 80-90 meters, while some sellers advertise 30 m, 50 m, and o
Android source code: ListView adapter ModeMode definition The adapter mode converts an interface of a class into another interface that the client expects, so that the two classes that cannot work together due to interface mismatch can work together.Use Cases Using Power interfaces as an example, the power supply of laptops generally accepts 5 V voltage, but the voltage of wires in our daily life is general
2006.1.5 Li Jianzhong The concept of adaptation (conversion) is everywhere. Adaptation, that is, the original incompatible interfaces are converted into compatible interfaces without changing the original implementation. Motivation) In software systems, due to changes in the application environment, we often need to put "some existing objects" in the new environment for application, however, the interfaces required by the new environment are not met by these existing objects. How can we cope
Adapter Pattern)Before the formal start, let's first think about a few questions: if the existing new project can use a lot of legacy code in the old project, are you planning to finish the new project from the beginning or understand the module functions and interfaces of the old project? If you have learned about the legacy code and find that several important functional module interfaces are different (because they may come from multiple old projec

Concept:The adapter mode, also known as the adapter mode, is one of the stereotype patterns that can change the interface form of an existing class (or external Class) through the adapter mode.For example: We use the computer, the home power is 220V, and our computer is 18V, then if we directly connect the power to the computer, will certainly lead to computer bu
