The difference between a class adapter and an object adapter

The main difference between the two is that one adapter is the same type of application.

The other type is specifically targeted such adapters, and the two are the correspondence of the same device.

The main difference between the two is that the two of them are voice actors, and the corresponding audio and video objects are different.

But there should be some differences between losing money and object configuration, so steaming and drying can dry the gold water, so I think this school is still very good for two minutes.

Regardless of the theory, the adapter mode is used: Let's say you have a power supply with a voltage of 220V, but you have two or more appliances.

The difference is the difference in the material between the two of them, the way of use may be different, and then the difference in the material may be different.

There is actually no difference between the two, but if I had to choose, I think the first one might be a little better.

That's the ovulation orientation culture mechanism, so that their gender experts can be a little casual to do the proportional performance.

The adapter is at the part of the sensor switch, and the registration will remind you at the same time, and you need to stop it urgently.

Adapter this you also go to check whether this is a matchmaker some of the situation, learn more.

How many objects and what is the scope of application? You can arrange it according to its instructions.

The difference between a similar orchestrator and an object adapter is not too big, but it belongs to the same substance.

The difference is that if you are an airplane, their object is actually different.

The difference between a collocation and an object adapter is that they are for different products.

In these two aspects, their functionality is different, and the effect of use is different, so in this regard, we must distinguish clearly, only in this way can we achieve a good effect.

The adapter mode is another two different modes: the class adapter and the object adapter.

What's the difference?

1. The object rejuvenation adapter is connected with the adaptive through delegation, that is, it holds the adaptive object, which is a dynamic way; The class adapter is connected to the bridge trapped adaptee through integration, that is to say, the class adapter inherits the adaptee and implements the target method, which is a static way.

2. Since the object adapter is connected with the adapter in a dynamic way, it can adapt to different adaptation sources and their subclasses.

3. The class adapter can redefine the implementation behavior, while the object adapter is more difficult to redefine the adaptive behavior, but it is more convenient to add the behavior.

Try to use the implementation of object adapters as much as possible, using synthetic aggregation more and inheritance less.

Multi-protocol** Supported protocol adapters include: SNMP, TL1, RMI, Corba, HTTP, and HTML adapters.

In the actual development process, we often encounter such a thing, we develop a base class based on the initial requirements, and only learn about the detailed requirements or the requirements have changed during the development process. The interfaces in the development work have already been defined and coded on a large scale. At this time, if you change the definition of the interface, it will cause a lot of repetitive modification work in the encoding, and then there may be semantic errors or logical errors caused by incomplete modifications.

Semantic errors can be found during the compilation phase, and if a logical error occurs, the consequences can be severe, even enough to cause the system to crash. This is where the design approach of adapter mode comes in.

The power adapter, also known as the external power supply, is a small portable electronic equipment and electronic appliances power supply voltage conversion equipment, its role is to convert the 220 volt high voltage at home into these electronic products can work about 5 volts to 20 volts of stable low voltage, so that they can work normally. It is also a small portable electric orange imitation equipment and electronic and electrical power supply conversion equipment, which is generally composed of a shell, a power supply transformer and a rectifier circuit, which can be divided into AC output type and DC output type according to its output type; According to the connection method, it can be divided into wall type and desktop type. Let's take a look at the detailed classification and advantages and disadvantages of power adapters.

There are two main types of power adapters, linear power supply and switching power supply. Linear power supply is to transform the AC power through the transformer, rectifier circuit rectification filter to obtain unstable DC voltage, power adapter to achieve high-precision DC voltage, must be adjusted through the voltage feedback circuit output voltage. Pros:

This power supply technology is mature, the circuit is simple, and there is no interference and noise that switching power supplies have. Disadvantages: The voltage feedback circuit is the best working state of Soxiang, the power consumption of the adjustment tube is large, the conversion efficiency is low, and the weight of the equipment is large due to the use of inductive transformers.

The development space of switching power adapter is becoming more and more extensive, and the development of high frequency makes it smaller and thinner, and the noise is getting smaller and smaller, and the anti-interference performance is greatly enhanced. The devices used in switching power adapters are mainly diodes, transformers, and so on. Miniature low-power switching power adapter.

This type of power supply is slowly entering the life of the public, and eventually it will replace the application of transformers in our daily life. For example, digital display watches and smart watches, of course, mobile phone chargers, etc., Xiaosui These wide applications are very beneficial to people's lives. Especially now that the country is promoting the construction of smart grids, it will naturally have higher requirements for electric energy meters, and I believe that it will eventually replace the related applications of transformers in these electric energy meters.

Reverse series switching power adapter: The biggest difference between this Yebu switching power adapter and the general series switching power adapter is that the power supply it outputs is negative voltage, while the output of the general series switch is just the opposite. At the same time, it is thought that the energy storage inductor set by it can only output the relevant current to the load when switching the shorts, so in the same environment, the current of the reverse series switching power adapter is twice as small as that of the ordinary switching power adapter.

Switching power supply is a kind of power supply that uses modern electronic technology to control the time ratio of switch on and off, and maintains a stable output voltage. Cons:

The interference to the power supply circuit is large, and the difficulty of maintenance is greater than that of the spine when the fault occurs.

The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances, which is generally composed of a shell, a power transformer and a rectifier circuit, and can be divided into AC output type and DC output type according to its output type; According to the connection method, it can be divided into wall type and desktop type. It is widely used in the first child and mother machine, game console, language mountain reply reader, walkman, notebook computer, cellular and other equipment. There is a nameplate on the power adapter, which indicates the power, input and output voltage and current and other indicators, pay special attention to the range of input voltage, this is the so-called "travel power adapter", if you go to the country where the market is only 100V, this feature is very useful, some parallel laptop socks are only sold in the place of origin, there is no such design, and even only a single input voltage of 100V, which will burn out when plugged in under the 220V mains voltage in China.

Summary. The purpose of creating an adapter object is to adapt two incompatible interfaces so that they can work with each other. With adapters, we can convert one interface to another without changing the existing **, so that they can communicate and interact normally.

The adapter object acts as a middleman, transforming two interfaces that would otherwise be mismatched so that they can work together seamlessly. In this way, we can reuse existing ones without having to modify them, improving reusability and maintainability. The adapter pattern is often used in software development, especially when modules developed by different teams need to be integrated.
