4. Adapter Mode SummaryIn the object adapter mode, the adapter is associated with the adaptation, and in class adapter mode, the adapter is an inheritance relationship to the appropriate person. whether an object adapter or a clas
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
1. Introduction to Adapter ModeIn our daily life, we will often come into contact with the adapter mode, such as our charger, different phone interface types may not be the same, this time as long as a switch interface , you can solve our problem. This switch interface is our adapter.DefinedThe adapter mode transforms the interface of one class into another inter
Introduction Yesterday, when charging the new MP3 player, it was found that the MP3 player only provides a USB interface charging method, and its charger cannot directly charge the USB interface, smart manufacturers installed a USB Interface Converter on the charger to solve the problem. This USB interface adapter is the adapter that we will talk about today. In software development, encoding techniques sim
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
Adapter mode (Adapter):1. Concept: Convert the interface in one class into another interface that the customer wants, so that those classes that cannot work together because of incompatible interfaces can work together.2. Role in the pattern1 target interface: the interface that the customer expects. The target can be a specific or abstract class, or it can be an interface.2 classes that need to be adapted:
3. Socket network communication design and implementation------Class adapterIn addition to the object adapter mode, the adapter pattern also has a form, that is, the class adapter mode, The biggest difference between the class adapter pattern and the object adapter pattern
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

Overview In order to meet the needs of actual projects, due to changes in the application environment, some existing objects need to be put into the new development environment, at this time, the new environment and the interface of this object cannot be directly connected, that is, they cannot know each other and exchange information. To meet this "change", how can we leverage the good implementation of existing objects, at the same time, the interface can meet the requirements of the new envir
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
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
Overview: In the process of software development, we often need to reuse some of the "existing objects" we have previously developed, but these "existing objects" cannot meet our new application environment. How can we reuse these objects well to meet our application environment? This is what the adapter is trying to solve. Intent:Converts an interface of a class to another interface that the customer wants. The
A communicator contains one or more object adapters. an Object Adapter sits at the boundary between the ice run time and the server application code and has a Number of responsibilities: • It maps ice objects to servants for incoming requests and dispatches the requests to the application code in each servant (that is, an Object Adapter implements an up-call interface that connects the ice run time and

DescriptionIn order to solve the problem of incompatible interfaces the introduction of an interface compatibility mechanism, is the adapter mode, which provides an adapter class to convert the interface provided by a third party to the client's desired interface. Examples of life: mobile phone charger to convert 220v power supply to the appropriate voltage to the phone to charge. This charger is the right

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
