How to design a universal callback mechanism ManyProgramA general callback mechanism is required. This callback mechanism does not need to care about their class types. For example, in an event-driven system that calls GUI component member functions, the actual type information is not known before the call. In this case, you can create a general callback template to streamli

of screen space." "I think this is the product manager imposed on the user's needs, because in the process of using the research, rarely heard users feedback is" I think this place empty, good waste. It is good to think about maximizing the use of space, but if you sacrifice the user's operating habits for your home products, then there is no moral integrity. As an interactive designer, from the product developer's point of view, the class is to be divided, but the difference is too big to be

modified the class it belongs to.Strategy: Define a series of algorithms, encapsulate them one by one, and make them interchangeable with each other. This mode allows the algorithm to be changed independently of the customer using it.Templatemethod: Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. Templatemethod allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Visitor: Represents an oper

has a general understanding. I think it is not an exaggeration to use the "authoritative guide for C ++ Beginners" label. To learn a new thing, the most important thing is to be able to master the basic concepts of orthodox correctness at the entry stage, and not to bend around during the learning process.Path. (Think about the diligent and well-performing folk scientists, I think their main disadvantage is that they have not been trained by formal disciplines and learned what is wrong at the

. The domain model is actually a common language for communication between domain experts and analysts and developers. The essence of domain-driven design is "to digest a large amount of knowledge, and finally generate a model that reflects deep-level domain knowledge and focuses on key concepts ". the core idea of this book is to use a model as the basis for implementation,

"Design Mode" (GOF): Not recommended for beginners to see. These four are PhD levels, they are the first to propose design patterns, high theoretical level, although a thin one, but the text is relatively obscure, but also lack of easy to understand examples. When you get to a certain level, if you are interested, you can look at it."Head First design mode": Good

Finally, I have read Mr. Zhang Yi's book "Essentials and patterns of software design", and I am deeply impressed by his understanding and explanation of software design, I have a new understanding of the software design process and the use of the model. Therefore, I think of this b
