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

Design patterns are a set of reusable, most known, categorized purposes, code design experience Summary. Design patterns are used in order to reuse code, make code easier for others to understand, and ensure code reliability.The origins of

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

From the beginning to the end, I read the design mode and wrote the blog of the design mode for nearly half a year. How can I say this? It's very bitter and tiring. Now I feel like my mind is full of paste. Java has given me a profound and profound feeling.

Recently, I was reading gof's design patterns. Before that, I saw John vlissides's design patterns in meditation. In the "Meditation" p42 footer note, the author mentioned "In C ++, such a definition is difficult to implement through any mandatory method [schmidt96a]. For example, if you use a simple # define statemen

be dependent? What is the difference between reference and dependency?This is a good question! In some cases, a class retains the reference of another class, but this class does not call the method of another class, but exposes the reference of another class for external calls.For example, if Class1 has a certain attribute Class2, you can access this attribute to obtain the instance of Class2:Class1 = new Class1 ();Class2 = class1.Class2;Although Class1 references Class2, it does not call the C

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 easy to add new operations, which is to
