Design Patterns-understanding of appearance patterns Appearance mode: provides a consistent interface for a group of interfaces in the subsystem. This mode defines a high-level interface, making the subsystem easier to use. In the data room charging system, the appearance mode is used to remove the coupling between the U layer and the B layer. According to the pr

I. Overview of the pattern The Strategy mode (strategy pattern) is similar in shape to the state mode, but somewhat different in intent. The intention is to make these algorithms interchangeable and provide a way to select the most appropriate algorithm. In my application of OOP design process Evolution (iii) This article applies to the Strategy model, in the book's rent calculation on a variety of situations, each type of

(class or object combination). Effect (Consequences) It describes the effect of pattern application and the problem that the usage pattern should weigh. Although we do not always refer to pattern effects when we describe design decisions, they are important for evaluating the costs and benefits of design selection and understanding usage patterns.

Command mode, which is the mechanism that encapsulates a common operation. If you are familiar with C or PHP, you may have encountered the command, which is equivalent to a callback (callback) in the program. Callbacks typically use a function pointer or data structure such as a string and array implementation in PHP, which is an abstraction over a method invocation that absorbs all the object-oriented benefits: compositing, inheritance, and processing. For example, the

$title; function __construct ($author _in, $title _in) { $this->author = $author _in; $this->title = $title _in; } function Getauthor () { return $this->author; } function GetTitle () { return $this->title; } } Class Bookadapter { Private $book; function __construct (Simplebook $book _in) { $this-

system development progress.There is also some advice: do not focus too much on the "design Patterns" of the program. Sometimes it's easier to write a simple algorithm than to introduce a pattern. In most cases, the code should be easy to understand and even cleaner to read. However, in large projects or frameworks, there is no design pattern to organize the cod

I. Description of the pattern There are a series of objects in my program, like we're going to have a bowl of rice, a cup of coffee (Coffee) ..., to take advantage of them, we have to generate them in the program according to the user's requirements, and then call the new operator one at a, This way the client will know the corresponding class information, the generated code is obviously not flexible. So we can not use the specific classes in the code, but just to show what we need, and then we
