The importance of the design pattern is unnecessary. Various design patterns are widely used in actual projects. I. Simple factory mode and factory Mode I know a little about UML. When I look at this class diagram, I know what the factory model is for. To put it bluntly, it is to provide an abstract base class interface, so that you do not need to remember

Java Design Pattern template method pattern, java Design Pattern TemplateTemplate Method Mode Defines the skeleton of an algorithm in an operation, and delays some steps to the subclass. The template method allows the subclass to redefine certain steps of an algorithm withou

Java design pattern: appearance pattern; java Design Pattern appearance I. Introduction The appearance mode (Facade) hides the details and complexity of internal subsystems and provides the client with the same Calling Interface, making the complex system easy to access and

Design Pattern-strategy pattern, design pattern-strategy Rule ModeDefines a series of algorithms, encapsulates each algorithm, and enables them to replace each other. The rule mode allows algorithms to change independently of customers who use it. Abstract policy role: a p

Php design pattern observer pattern, design pattern observer The core of the observer mode is to separate the customer element (observer) from a central class (subject. When the subject knows that an event occurs, the observer must be notified. At the same time, we do not wa

Php design pattern-Observer pattern, php design pattern observer In web applications, some small-scale data and business changes usually require changes to other related business data. In this case, the observer mode is suitable. The Observer mode is usually implemented by u
