mux logic

Web| News Brief introduction The requirements of business applications always change with the changing trend of the business environment. Decisions are rarely immutable, and competitive pressures require flexibility in the design and implementation of business logic to quickly adapt to changing requirements. Typically, changes to the business logic must be done by the developer, and then thoroughly tested,

The business logic layer is the application brain Responsible for handling the core business of the system, Modeling user-defined processes, Responsible for communications between the data access layer and the presentation layer, It cannot be changed because of database changes or terminal changes. The specific implementation of the business logic layer is as follows: BLL-business

the program is mainly about the operation of data, to represent and manipulate the data, we introduce the basic types, classes and interfaces, the following section, we introduce the Java in the representation and operation of a special kind of data mechanism- enumeration. ----------------To be continued, check out the latest articles, please pay attention to the public number "old Horse Programming" (Scan the QR code below), from the introduction to advanced, in layman's words, Lao Ma and you

enumeration types are more concise, secure, and convenient.We've mentioned anomalies before, but we haven't discussed them in depth, let's discuss them in the next section.----------------To be continued, check out the latest articles, please pay attention to the public number "old Horse Programming" (Scan the QR code below), from the introduction to advanced, in layman's words, Lao Ma and you explore the nature of Java programming and computer technology. Write attentively, original articles,

Exception cannot be used for logic processing Exception is error processing, but cannot be used for logic processing. Suppose we encapsulate a msgqueue. This class is responsible for collecting client messages from one receiving thread on the server side, and the other working thread is responsible for extracting messages, and process the message. ClassMSG {...};ClassMsgqueue {Public:VoidPut (MSG)Throw(

, if there is a double shot, they are said to be equal, such as [0,1] and [3,4], denoted by a symbol ~. Obviously, the equipotential is an equivalence relationship.P-Set: The set of problems that can be received by deterministic Turing is called P-setsNP set: A set of problems that can be received by a non-deterministic Turing group called NP setsComputable: Do not understand the concept, do not seeFirst order logic: a reasoning system consisting of a

In the early period of the last century, the mathematics research has changed very much, the logical axiomatic method deeply integrates the mathematics, causes the mathematics deeply rooted, the rapid growth. 11-13 the British mathematician Russell (Bertrand Russell,1872-1970in its three volumes of the classic "Mathematical Principles" in the initial completion of the logic into the mathematics of the attempt. This is a profound event in the history o

Background:Recently, due to the project needs, the Java-based DICOM standard implementation Library, namely Dcm4che, is beginning to be contacted frequently. Unlike previous DCMTK and fo-dicom, the Dcm4che Toolkit is part of the entire Dcm4che project and is used only as a toolkit for parsing dicom formats and Dcm4chee is a Web application hosted in JBoss as. So it adds a lot of business layer logic inside. This time in the practical application encou

From: http://broadcastengineering.com/mag/broadcasting_dolby_pro_logic/ In the same way that digital technology has replaced analog, surround sound is replacing stereo. phenomenal sales of DVD-video players and home theater systems confirm that consumers enjoy sound from all around. savvy broadcasters understand that they must some how squeeze 5.1 channels through their 2-channel audio signal paths. While matrix surround systems suchDolby Pro

Generally, for a class that meets most of our needs, you can create a subclass of the class and only change what we don't expect (the part that needs to be changed ). Just inherit a class, you can reuse the code of this class. What a wonderful thing! However, as with most beautiful things, over-using is often bad. According to the replaceable principle (LSP), Public inheritance has a conceptual practical significance. It represents a is-a relationship. Before using inheritance, be sure to check

In the development of four-nation military games, use flex online game development-four-nation military games (5)-refine the chess development api, we have extracted the first api for chess game development-FlexChessAPI. This api design principle is based on the state machine and event-driven flex mechanism to make the development work simple and easy. Now, we use this api for the first time to develop a Chinese chess game. For a mature developer, I believe that you only need half a day to make

Friends interested in AI may have seen the Rai Yonghao translation of the "Finite state machine era of the end of the 10 reasons", which discussed the state machine many drawbacks. At the same time in the PPT (attached) described the behavior of the many advantages of the tree, here is not to repeat. More to want to summarize their own play for a while after the behavior of some of the tree experience.Personal experience:State machine to implement AI more in line with our naïve expression of tho

Part 3: Design Logic Layer: core developmentAs mentioned earlier, our solution is as follows:Below we discuss the structure of the entire application, separated into different layers according to the logical dependencies of the different components in the application, and the communication between the layers and the layers passes or does not pass the restriction. Hierarchies are architectural styles that address maintenance and scaling issues during t
