Adapter mode is a very common pattern in software development, and the function of this mode is to enable two incompatible interfaces to work together. Most of the time we are using this pattern consciously or unconsciously. Because two interfaces are not compatible, the task of the adapter is to adapt the data or objects so that the calling interface can use the results produced by the other interface. The
SpringMVC adapter pattern code example, springmvc Adapter The adapter mode is used here. Due to different Controller types and multiple implementation methods, the calling method is not definite. If you need to call the Controller method directly, you need to write the following form in the Code: if(mappedHandler.getHandler() instanceof MultiActionController){
in the development of Android, we often use the ListView, GridView, each time the code needs to write their corresponding adapter, write a lot of feeling very irritable, because the basic programming ideas are the same, but each time to repeat to write, So can we abstract them into a generic template, so that you do not have to repeat the same code every time, the direct re-use, this is not better, we will introduce an open source project Base-
Adapter mode is a structural design pattern Design Intent: Transform the interface of one class into another interface that the customer wants. The adapter mode makes it possible for those classes that would otherwise not work together because of incompatible interfaces to work together. The pattern, like the name of the adapter, is to enable the old interface

The principle of this pattern is very simple, please see the example below. 1. Class Diagram 2. Java Implementation CodePackage cn.edu.ynu.sei.defaultAdapter; /** * Interface a* This interface has 5 methods, F1~f5 * * @author 88250 * @version 1.0.0, 2007-8-31 */ public interface Interfacea { public void F1 (); public void F2 (); public void F3 (); public void F4 (); public void F5 (); } Package cn.edu.ynu.sei.defaultAdapter; /** * Default Ad
Vs 2008 When the interfaces provided by an existing component (Class Library) are inconsistent with those requested by the current customer system, use the adapter mode to convert the interfaces of existing components to those requested by the customer system. 1. Mode UML diagram2. Application Currently, we have a set of existing text logging components that provide a set of clientCodeThe requested interface.However, the client code requests a
Serverfirst these two classes have been hit into the jar bag, can not be modified ah ... "Your leader is a little awkward.What This is not the pit father, do I have to change the interface? "You are already in tears.""This is not necessary, in this case you can use the adapter mode, this mode is to solve the problem of incompatibility between the interface appears." ”In fact, the use of the adapter mode is
The following conditions need to be met: 1, compared to the new adapter connection computer interface, must be the same interface with the Huara adapter. 2, look at the adapter's label in the "Output/output" Item after the number, the legend shows 20v-4.5a,20v for this adapter output voltage, the new adapter must be

Explain:Transforms the interface of one class into another interface that the customer wants. Those classes that would otherwise not work together because of incompatible interfaces can work together.Solve the problem:What is needed is, but cannot be used, and cannot be modified in a short time. That is, make a function suitable for different environments.In the development, the system data, behavior are matched, but the interface does not match, you can consider the adapter.It is desirable to r

What is the role of adapter? In fact, it is a bridge between the view interface and the data. We can be seen as an understanding of interface data binding, and the data it manipulates are generally more complex data, such as arrays, lists, databases, collections, etc.The commonly used adapters are:(1) arrayadapter; array as the data source, filled with arrayadapter(2) Simpleadapter; list as a data source, populated with Simpleadapter(3) Simplecursorad
Adapter Mode: Converts the interface of a class into another interface that the customer expects. Adapters allow classes that are incompatible with the original interface to work together.Direct.
