BackgroundThe behavior model mainly controls the behavior between classes. This is very important for decoupling, how to divide the classes of their respective roles, grasp the granularity, control their message flow is very important, these models are sometimes more strange. Take it slowly.Introduction to the ModelLet's look at 6 patterns of behavioral design.1. MEMENTO (memo) 1.1 Intentionscaptures the in

5 practical application of design patterns: Factory method patterns, 5 of design patternsDefinition of factory method modeThe factory method model is widely used. The factory method mode is widely used in Java APIs: java. util. the iterator method of the Collection interface is an example of a well-known factory method

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

on the structure of head first design patterns. It can also be called the study notes of this book, but it is more about the gradual explanation of the original book, we strive to join in more personal thoughts and opinions, hoping that they will eventually resonate with everyone. Several heroes and their predecessors

The basis of reusable object-oriented software-design mode, with its reusable design intention, ingenious logical thinking by the vast number of object-oriented program design is sought after. But many programmers often turn the question of thinking into what patterns they encounter. This kind of confucianism、the think

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

experience reach a certain level, and it also means to summarize a lot of good design experience, however, it may not be the case that "no teacher can do anything", or you can say that, on the basis of level and experience, it is time for the system to learn the "mode, it is helpful to learn the experts' summary and verify your own shortcomings.
