Overview
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. So how should we deal with this "Migration change "? How can we make good use of the existing object and meet the interfaces required by the new application environment? This is the Adapter mode des
Structural patterns (structural pattern) describe how a class or object can be combined to form a larger structure. The structure pattern describes two different things: a class and an instance of a class. According to this point, the structure pattern can be divided into the structure pattern of the class and the structure pattern of the object.
Subsequent content will include the following architectural patterns: Adapter mode (

Problem Introduction: for example, if there are A-type and B-type nuts, you can directly use A-type screws produced by A-type nuts on a-type nuts, you can also directly use B-type screws produced according to B-type Nut standards on B-type nuts. However, because a-type nut and B-type nut have different standards, you cannot directly use B-type screws on A-type nut, and vice versa. How can we achieve this goal?
You can solve this problem by using an adapter
Adapter mode design ideas in life will often be applied to, such as when we are charging the phone, it is not possible to directly charge on the 220V power supply directly, but with the mobile phone charger to convert the voltage required to be able to charge the normal, otherwise it can not be completed charging, the charger has played a role in adaptation.1.

Usually causes the ping to fail: The router does not have power. For example, the power adapter is not plugged in, the router switch is not turned on, and so on. The r
There are two things that cannot be logged into the A9 management interface:
Situation A:A9 cannot log on to the admin interface before expanding.
Situation B:A9 cannot log on to the admin interface after expansion.

: A9
unable to log on to admin interface before extension
the interface can only be A9 by connecting the Extender before extending;
Step one: Make sure the computer/phone is connected to the A9 wireles
First, IntroductionFrom today onwards we begin to talk about "structural" design patterns, "structural" design patterns are as follows: Adapter mode, bridge mode, decorative mode, combination mode, appearance mode, enjoy meta-mode, proxy mode. The "created" design pattern solves the problem of object creation, and the "structured" design pattern solves the problem of the combination of classes and objects. Today we start talking about the first design

I. Adapter Mode
The adapter mode converts an interface of a class into another interface that the client expects, so that the two classes that the original interface does not match and cannot work together can work together.

Adapter mode (converter surface mode) is generally used for the interface, does not match the application or the system, and the intermediate Adaptation Layer class or object needs to be introduced. The adapter mode is used to solve the problem of interface inc
compositing instead of inheritance. Some behavioral object pattern descriptions describe how a set of peers can work together to complete a task in which either object cannot be completed alone.The creation pattern consists of: 1, FactoryMethod (factory method mode), 2, abstract Factory (Factory mode), 3, Singleton (singleton mode). 4, builder (builder mode, generator mode). 5, Prototype (prototype mode).The structure mode includes : 6, Bridge (bridging mode), 7,

I want to say the adapter mode, it should be more appropriate to mention the "voltage", "headset", "Charger" and "USB" examples. Just talk about your personal experience, my original mobile phone is NOKIA5730. Later did not know there is no country, but do not recommend you buy this phone, not applicable Kazakhstan.

Adapter mode (Converter surface mode), generally for the interface to be used, does not conform to the application or the use of the system, and the need to introduce the intermediate adaptation layer class or object case. The role of adapter mode is to solve the problem of incompatible interface between the two software entities.First, the definitionAdapter mode (Adapt

In computer programming, the adapter mode (sometimes called packaging style or packaging) adapts a class interface to what the user expects. An adaptation allows a class that cannot work together because the interface is not compatible, by encapsulatin
The adapter pattern transforms the interface of a class into another interface that the client expects, in order to eliminate compatibility issues with classes caused by mismatched interfaces. There are three main categories: The adapter mode of the class, the adapter mode of the object, and the adapter mode of the int
Today, we're going to comb the adapter pattern for Java design mode. Adapter, think of our usual use of the power adapter to know, is to put two incompatible things straightened out, can contact each other. Also in Java, is to let two need to coordinate the class, through the adapter to coordinate the line, that is,
