https://doi.org/10.1007/978-3-540-77853-0This chapter covers two GoF patterns: . and .. These patterns are closely related, so we‘ll discuss them together. The truth, though, is that the real design pattern is called . and that both Factory Method and Abstract Factory are simply variations that are important, but certainly not as important as the main thing.值得尊敬 发表于 2025-3-25 13:12:47
https://doi.org/10.1007/978-3-540-77853-0Singleton is by far the most hated design pattern in the (rather limited) history of design patterns.

BuilderThe Builder pattern is concerned with the creation of . objects, that is, objects that cannot be built up in a single-line constructor call. These types of objects may themselves be composed of other objects and might involve less-than-obvious logic, necessitating a separate component specifically dedicated to object construction.行乞 发表于 2025-3-26 20:46:26
