Why do you want to learn design patterns Getting started with software architecture and design is about understanding and mastering design patterns. Design patterns have become a "stan
persistent Class C type () call this abstract method absmethod (C) in the method, so that the persistence class is injected into the methoda () method, and the data in the method can be persisted. Then, you only need to use Class D to inherit Class B and implement the absmethod (c) Method of class B. In this way, you can indirectly pass the C instance to the methoda () method.This blog does not explain the template design pattern, but emphasizes how

The factory method pattern and the abstract factory pattern in the design pattern have been unknowingly used in the programming, but often only practice did not carry out theoretical guidance, so feel that there is a 1:30 path to the monk without the system to learn the feeling of not practical. Now summarizes the abstract factory patterns used in the previous project to enhance understanding of the factory

I will definitely work towards the architect in the future. Writing a blog has many advantages. One of them is that to write a good blog, you must read a lot of information and consider a lot of words. All my blogs are written in advance in the document, then, from
patterns-getting along with patterns 14. Remaining ModesDesign Mode Introduction Mode: each mode describes a problem that occurs repeatedly around us and the core of the solution to the problem. This is the most classic definition of patterns, written by the architect Christopher Alexander. If this is the first time you see this sentence, most people will feel a

The framework mainly records the common design decisions in software applications, and emphasizes design reuse. Therefore, the design model must be used in the framework

pattern is to encapsulate some action that is applied to a data structure element. Once these operations need to be modified, the data structure that accepts the operation can remain unchanged. The visitor pattern is suitable for systems with relatively indeterminate data structures, which frees up the coupling between the structure and the operation of the structure so that the set of operations can evolve relatively freely. The visitor pattern makes it ea

unchanging and changing parts of common problems. The invariant part constitutes the pattern, so the pattern is a "guideline" for empirical extraction, and is validated in one-time practice, with different patterns at different levels, small to language implementations, and large to architecture. At different levels, the model provides different levels of guidance. The role of design
