This article mainly introduces the simple factory mode in PHP design mode programming. It provides an example of fruit sales and calculator design, for more information, see the simple Factory mode, which is also called the Static Factory Method mode. The simple factory mode is determined by a factory object to create a product instance. 1. several forms of fact

See a blog post on smashing, take an example to illustrate the correct expression in the interactive design, real expression and creative expression.Instance Source: http://www.smashingmagazine.com/... xamples-and-trends/ The page expresses meaning clearly, without ambiguity and confusion. This is also the reciprocal design of the minimum requirements.The follow

When to use(Singleton mode): When creating objects such as thread pools, caches, and so on, we can use a singleton pattern to avoid wasting resources. But if you want to store global data such as product prices, the singleton pattern becomes a reverse pattern, and you should consider replacing it with other methods. Note: The singleton has become a reverse pattern here, and we can avoid it with the following techniques: 1. Injection of dependency; 2. Use the factory

icon, gives two most common example, first is "returns to the top" Small button, this button seems simple, but very useful, if your content page content more, across a large range, I believe that the use of this button to replace the wheel will make your content page for visitors more friendly, which we can from some large sites, micro-blog, Baidu Encyclopedia can see this small button, The following figure shows the Sohu back to the top of the small

When writing a program, we often run into scenarios where we plug a bunch of algorithms into the same piece of code and then use IF-ELSE or switch-case conditional statements to determine which algorithm to use. These algorithms may be a bunch of similar class functions or methods to solve related problems. For example, a routine that validates the input data itself can be any data type (such as NSString, cgfloat, etc.), and each data type requires a

Whether your project is using swing technology or not, I would say that swing is a well-designed Java package that is filled with the wisdom of the master. If you learn Java and you can't write a button, it's just as if you're learning Visual Basic and you don't use a button, which is absolutely unforgivable. Swing technology has been used in foreign countries, because of the free Java, easy to learn and the full trust of Java technology, a lot of companies early on the application of everything

I will upload my new book "self-writing processor" (not published yet). Today is the eighth article. I try to write this article every Thursday. 2.7 Circuit Design Example In this section, we will design a simplified processor command acquisition circuit, through which we can use the example to understand the use of T

process development is often different from the timer used in industrial control or algorithm. The timer used in industrial control or algorithm must be accurate, however, the timer of a business flow may require work days, efficiency, and other functions. It can reflect business time and cycle changes, so that business processes can run, manage, control, and count based on specific time coordinates. I will define it as a time engine. The time engine consists of two parts: Timeline, including

layout demand carries on two times composition, actually also is two times the composition synthesis application. Sometimes you have to use the cutting method, Sometimes you use the Add method. No matter what the method, finally can show a very good effect that is two times the successful use of composition.

The singleton mode, which can be said to be the simplest of the 23 design patterns of GOF.This mode is relatively independent compared to several other modes, it is only responsible for the control of their own number of instantiations of a single (rather than consider the user to produce what kind of instance), very interesting, is a feeling very clean mode, I like this mode.In many parts of Android, a singleton model is used, this article takes the

Example of a form design that uploads multiple files in PHP, Multiple file uploads and individual file uploads are handled the same way, with only a few input forms of type "file" in the client, and a different "name" attribute value specified. For example, in the following code, you can have the user select three local files to pass to the server together, and
