camel design patterns

The following 23 design patterns are mentioned in the design pattern book:Abstractfactory: Provides an interface to create a series of related or interdependent objects without specifying their specific classes.Adapter: Transforms the interface of a class into another interface that the customer wants. The adapter mode makes it possible for those classes that wou

Six principles of design patterns (6) -- six principles of open and closed Design Patterns Definition: The objects (classes, modules, functions, etc.) in the software should be open to extensions, but the modifications should be closed. Personal Understanding: In general, the open/closed principle refers to various com

the parent class, the post-condition (that is, the return value of the method) of the method is stricter than that of the parent class; Dependency inversion principle: Invert dependency to dependency Interface Upper-layer modules should not depend on lower-layer modules. They all depend on an abstraction; Parent classes cannot depend on child classes. They all depend on abstract classes; Abstraction cannot depend on or depend on abstraction; Interface isolation principle: The dependence of a

Statement in advance: I am referring to Chen and Wang Bin's "grinding design mode" for the study of design models. I am reading this book carefully and think it is quite good. Then, I sorted out some knowledge points in the book. Although they were not original in the true sense, I also sorted out some other knowledge points, so I dared to write originality on my blog. I hope the author of this book will no

Before understanding the differences, let's look at how the design patterns work and make better use of one of the two (MVC design and MVP. The (MVC design and MVP) model has been used for several years. A key problem to be solved is the main focus of object-oriented, separated user interfaces and business layers. Ther

So far, I have finished learning several design patterns of the created model. Let's take a look at them. It takes a short time. It is better to create a model that is relatively simple and will not be so smooth in the future. since there is no real practice in the project, so far, I think I have not mastered it, just a little understanding of the design model.

Design patterns can be divided into three types depending on the type of use:1. creation mode : Factory (Factory mode), Singleton (single State), Builder ((builder mode), Prototype (prototype mode), factory method mode.2. structure mode : Flyweight (Shared mode), Bridge (bridge mode), Decorator ((decorative mode), Composite ((combo mode), Adapter (adapter mode), Proxy (proxy mode), facade (appearance mode).

type T, and the return value of the same method (overloaded or overridden) of the subclass is S, then the Richter substitution principle requires s to be less than or equal to T. 3. Dependency inversion principle (DIP): The high-level module should not rely on the bottom low-layer module, both should rely on its abstraction; Abstraction should not depend on details; Detail should be dependent on abstraction.
