I will give you a detailed analysis of the Illustrator software and share with you the tutorials on creating decorative posters quickly.Tutorial sharing:All right, the above information is the detailed tutorial for quickly making decorative posters for the users of Illustrator's software, users now see that the production method is very clear here, so you can follow the small series of tutorials to crea
This is the second time I've made a project on the Nectar model. This time it is based on the latest version of the mannose model to do design patterns to explore the implementation.
Before you begin, say a few words:
JavaScript is running on top of the browser, and design patterns are commonly used in large projects, which combine to produce a center, two basic points.
The so-called One center: stable operation, performance first.
Browser to run the program, want to bigger projects, the fir
Decorative design pattern: Provides enhanced functionality based on existing featuresThe origin of the decorative design pattern:Reader----TextReader----MediareaderTo provide buffered read functionality for subclassesReader----TextReader----Bufferedtextreader----Mediareader-----BufferedmediareaderReader----TextReader----Bufferedtextreader----Mediareader-----Bufferedmediareader----Otherreader-----Bufferedoth

In the classical object-oriented programming, it is often necessary to encapsulate or hide a state of an object in the object, only through the object's amplitude and access to these states, exposing only some important state variables can read and write directly.We can simulate implementing a private instance field by decorating the variable (or parameter) within a constructor, and invoking the constructor creates an instance.function Range ( from, to) { //do not save the battle as an object
functions are woven without knowing it.
2: Use the decoration mode to make effects similar to AOPThe following example shows how to use the decoration mode to add some common functions, such as permission control, logging, and transparent functions back to the business function module to achieve similar effects of AOP.(1) first define the business interfaceThis interface is equivalent to the component in decorative mode. Note that the interface is u

The decorator mode, also called the adorner mode. As the name implies, is to wrap a layer of objects, packaging. Let it become the object of your liking. This pattern is often used in our development, and it is a technique to deal with problems, that is, to not let the program be inflexible or to extend the program.
(i) When to use it ""
1. You need to give the class an extension, or attach a responsibility to the class.
2. Dynamically add a feature to the class that can be revoked dynamicall
In the object-oriented (OOP) design pattern, the decorator is called the adornment mode. The Deco pattern of OOP needs to be implemented through inheritance and composition, while Python supports decorator directly from the syntax level, in addition to the decorator of OOP. Python's decorator can be implemented using functions or classes.Decorator can enhance the function of functions, although the definition is a bit complex, but it is very flexible and convenient to use.Write a decorator that

More flexible than static inheritance2. Avoid having too many features in a class at the top level of the hierarchy3. The adorner is not the same as the object it decorates, and cannot be relied upon for object representation4. Many small objects are producedReference
