(); } An object adapter can fit multiple classes with a suitable fit. You only need to pass different matching classes in the adapter construction method. With flexibility. Advantages of class Adapters: 1, because the adapter class is a subclass of the adapter class, it is possible to replace some adapters in the adaptor class to make the adapter more flexible. Disadvantages of class Adapters:

, can be invoked at any time, do not require the developer to do accurate processing, so overuse of session variables will cause code unreadable and difficult to maintain. Although "You can use the session variable directly at any time you want to use it without having to declare it beforehand, this approach is close to the use of variables in VB." After you use it, you do not have to consider releasing it, as it will automatically release. But, "who" thought there? What is the meaning of a var

(i) Comparison of the advantages and disadvantages of sequential storage structures and chained storage structures, as well as usage scenarios. 1 Advantages and disadvantages ① sequential storage, the storage address of adjacent data elements is also adjacent (logical and physical unification); requires that the addr

You can call the stored procedure by specifying the name of the stored procedure. The

connections (million levels) can correspond to a process5,nginx processing static file is good, consumes less memory . But Apache is undoubtedly still the mainstream, with a lot of rich features. So it needs to be paired. Of course, if you can be sure that Nginx is suitable for your needs, then using Nginx will be a more economical approach.Apache does not support multi-core to download the Chicken rib shortage, recommend using Nginx to do the front end, the back end with Apache.

If you are a programmer, 90% of project leaders will ask you during the interview. "How do you know the advantages and disadvantages of object-oriented programming" Let's first look at what others say. ===================================== Understanding of other people's OOP ==================== ============================Object-Oriented Programming (OOP) is a computer programming architecture. One basic

too flexible in hibernate. When you use EB to implement the persistent layer, you will find that eb is too clumsy, so you have no choice at all, therefore, you don't have to spend any energy designing a solution, balancing the advantages and disadvantages of the solution, and worrying about which solution to choose, because only the only solution is in front of you. You can only do this, no choice. On the

1. Keyword, for example: Background-position: Top right;Advantages: intuitive, high availability, consistent performance in various browsers.Disadvantage: The interval size is missing. three vertical (top, center, bottom) and three horizontal (left, center, right) can only combine up to 9 positions for you. there are no other mixed combinations. and it is difficult to use arithmetic for control like the other two numerical locating methods. 2. pixel

increase the size of your tempdb database.• In general, large objects, such as XML, make the large object heap memory pressure in GC, and you should consider migrating to the. NET 4.5 version of the GC large object heaps defragmentation feature.• You can consider storing XML as Byte [], which can be compressed (XML is not a very economical format).What is the cost of using EF and ADO? DataReader The cost of transforming the SQL query from LINQ to the cost of the object.You will have the same ov

Array: Memory is contiguous storage space, List: memory address can be discontinuous, each node of the list includes the original memory and the next node information (one-way list, two-way list two).Array Advantages: 1, occupy less memory space, 2, the data in the array can be randomly accessed, 3, the data lookup efficiency is high (memory continuous);List of advantages: 1, convenient data deletion, inser

Python indent syntax, advantages and disadvantages, python indent Python syntax is relatively simple-indent Indentation has the following advantages: One of the advantages is to force you to write formatted code, but there is no rule on whether the indentation is a few spaces or tabs. According to the Conventions,

expand the content of the Error object , human flesh see stack information, jump over, but at the moment local variables are long lost ... Special Miss Write / http ASP , you can use Visual Studio to debug the days of the code in your browser. PHP estimates are similar. Weak type is not rigorous, in the case of strict type requirements need to pay attention to abnormal conditions: such as receiving parameters need to be judged int, but all the PHP received can be used as a string, to their o

organizations pay for additional computing resources whenever they need it.If you are running a series of businesses that depend on any type of data structure and network management,Cloud ComputingThere is no doubt about the advantages that can be brought to you. There is nothing to compare with flexibility, customization, and ease of use. In fact, there are many phenomena that make cloud computing seem unstoppable. But what companies really need to

The pros and cons of single-threaded and multi-threaded The advantages of multi-threaded processingSynchronization applications are easier to develop, but are typically less efficient than multithreaded applications because they need to be completed before a new task can be started. If the synchronization task is completed longer than expected, the application may not respond. Multithreading can run multiple processes at the same time. For example, a

composite index, the total length of the columns that make up the composite index cannot exceed 900 bytes, which means that the composite column length cannot be too long; In a composite index, all columns must be from the same table, and composite columns cannot be created across tables In a composite index, the order of the columns is very important, so the order of the columns is carefully arranged, in principle, the most unique column should be defined first, for example, the index on (col1

LOB Advantages:1, ensure the transaction consistency of large objects.2, backup and restore including Big data object, it can be point-in-time recovery.3, all data can use a storage and query environment.LOB Insufficient:1, large objects in the cache accounted for a very large buffer.2. Updating large objects results in a large amount of data fragmentation.3. The database file may become very large.FileStream Adva
