Its function is mainly to compare operations, string matching, to determine whether the specified content exists, Loop through the collection for request forwarding and redirection, the following specify the purpose of the la

Implementation Background The series has been on the ground for so long that no business code has been written. In fact, I think so, because the business code of different game items is very large, business logic only you can not imagine, no planning greatly unexpected. If you want to be a more aggressive framework, the less business code is arguably the better. But think twice, still try to construct some game public business, also be the example co

Label:When we first get started with SQL, we filter to a row with a column value of NULL, typically in the following way: SELECT * from Table as T WHERE t.col=null www.2cto.com and in fact this kind of writing does not have the desired result. The workaround we found online at this time is to use: T.col is NULL. Although this method can get data, but I and some of the peers do not know why the t.col=null can not get a Col null row of this result.Recently I want to strengthen the knowledge of SQL

ObjectiveThe main realization of the second-kill business layer, the second-kill business logic mainly includes exposing the seconds to kill the interface address, the realization of the second-kill business logic. At the same time, three business classes were declared: Exposer, Seckillexecution, Seckillresult. Exposer is primarily used to implement an MD5 encryption when exposing an interface, preventing u

Artificial intelligence (AI) often has such a problem, that is what I want to do? What am I supposed to do? What do I need? So what is called intelligence here is the judgment given to an AI object, and the corresponding response it receives from judgment. Like, you go to the store to buy things, enough money to sell you, not enough to sell you, here will trigger two results, if you want to buy, then the clerk may have a corresponding measure. In fact, the clerk here is equivalent to what we cal

the general control room, the command center, where you can manipulate and manage the contents of a TV or box file. Open the following interface, u disk and local storage information at a glance, praise one! To open an external store for example, you can see that the file information is displayed very clearly. When you open the movie folder, select the movie and display the format and size below The rename operation is very simple. Open the video file after displaying th

logical AND, bitwise AND and the can be used as the logical AND operator, representing the logical and ( and ) , the result of the entire operation is true when the result of an expression on either side of the operator is true, otherwise, theresult is false,as long as there is a side of false. also features a short-circuit , that is, if the first expression is false, the second expression is no longer evaluated, for example, for an if (str! = null !str.equals (")) expression, when a when str

In 2013 sophomore summer, I learned after the compilation of C + +, ready to compile with the compilation of C + + to understand its language operation of the underlying mysteries, so ready to write a series of articles, but due to the time relationship, only wrote three articles. Now look at these articles, although some places are not mature, but the overall is quite deep, sorting here to facilitate later updates. An in-depth analysis of the references from the bottom and

Always feel that the model layer is only used to manipulate data, a lot of business processing in the controller, there is a claim that business logic is more suitable for the model layer, do not know which processing better! Look at the tp5.0, as if the business logic in the model, and then read some stickers, many say business logic in the model better. Links:

Logic (rationale), derived from classical Greek λόγος (logos), originally meant "words" or "words", but also extended meaning "thinking" or "reasoning". Logic is often considered to be a study of the evaluation criteria of argumentation, although the precise definition of logic is controversial among philosophers. The subject is also based, and the task of the

sqlexception thrown by test, the catch is used here, and for appexception, it is added to the throws statement of its own method, which means that the current method is not processed, or it is handled by the upper layer.Checked contrast unchecked ExceptionAbove, you can see the difference between runtimeexception (unchecked exception) and checked exception, checked exception must appear in the throws statement, the caller must handle, The Java compiler enforces this, and runtimeexception does n

Software-defined storage logic-Efficientandagilestoragemanagementinsoftwaredefinedenvironments Note: writing this may be a translation, or an understanding of this paper [1], or just my opinion. Compared with IOFlow, this paper pays more attention to the Software Defined storage framework (I think it is to use the existing framework to create a new framework and then use the existing Protocol ), instead of focusing on communication protocols like IOFl

Most people like to use adjectives to describe things, and rational people like to use logic to infer cause and effect. Some people can break through all kinds of things and the backwards and forwards, directly to the essence, through simple logic, quickly draw conclusions, this is a rare ability. Although most of the time, such people use more than 3 inferences, the lo
