Structure mode, a total of seven kinds: Adapter mode, adorner mode, proxy mode, appearance mode, bridging mode, combined mode, enjoy the meta-mode.First, the adapter mode:The adapter pattern transforms the interface of a class into another interface that the client expects, in order to eliminate compatibility issues with classes caused by mismatched interfaces. There are three main categories: The adapter mode of the class, the adapter mode of the object, and the adapter mode of the interface. F

Design Patterns (iii) AbstractFactory patterns-creation Models Abstract Factory mode is the most abstract and general factory mode in all forms. Abstract Factory mode refers to a factory mode used when multiple abstract roles exist. Abstract Factory mode provides an interface to the client to create product objects in multiple product families without specifying

Understanding design patterns-command patternsI have learned part of the design model, but I have never studied the system. I recently bought the big talk design model from Cheng Jie and recently want to learn it systematically. When I saw the command mode, I thought it was not very easy to understand, so I searched so

on request:　　Anyone who has used a servlet knows that, in addition to having a corresponding configuration in Web. xml, it is necessary to inherit an abstract class called httpservlet, and rewrite the Doget and Dopost methods (and, of course, just rewrite the service method).Many of the methods in the request object are used when the internal components interact with each other, such as setcomet, setrequestedsessionid, etc. (not listed here). These methods are not exposed externally, but must b

Adoption of design patterns in ANDROID-behavior patterns 1 responsibility chain model The purpose of the responsibility chain mode is to allow multiple objects to process requests, so as to avoid coupling between request senders and receivers. Connect these objects into a chain and pass the request along the chain until an object processes it. So that multiple objects have the opportunity to process the re

The public behavior in each subclass should be extracted and centralized into a common parent class to avoid code duplication. This is a good example of what Opdyke and Johnson described as "re-factoring to generalize." First identify the differences in the existing code and separate the differen

Abstract Factory is similar to the factory method mode. They all follow the open-closed principle and use the factory interface to create a derived factory and then create th
