? design pattern--Strategy mode1, Definition: Policy mode, also known as the algorithm cluster mode, is defined by different algorithm families, and can be replaced between each other, this mode allows the algorithm to change independently of the

Liu Bei is about to marry his wife in Jiangdong. Zhuge Liang gave Zhao Yun (Best Man) three tips before, saying that they had taken the opportunity to solve the difficult problem. Hey, don't say that it really solved the big problem, in the end,

Policy mode, as a software design mode, indicates that an object has a certain behavior, but in different scenarios, this behavior has different implementation algorithms. For example, everyone needs to "pay personal income tax", but "pay personal

Definition:Define a set of algorithms, encapsulate each algorithm, and make them interchangeable. Type:Behavior mode Class diagram: Policy mode encapsulates algorithms and encapsulates a series of algorithms into corresponding classes. These

I. Strategy ModeThe rule mode is intended for a group of algorithms,Encapsulate each algorithm into an independent class with a common interfaceSo that they can be replaced with each other. The policy mode allows the algorithm to change without

The rule mode is intended for a group Algorithm , Encapsulate each algorithm into an independent class with a common interface, so that they can be replaced with each other. The policy mode allows the algorithm to change without affecting the

Let's first understand the following basic concepts before starting this section. ApplicationProgramDomain The application domain (appdomain) can be considered as a lightweight process. A Windows process can contain multiple AppDomains. The

Preface Rule mode: it definesAlgorithmFamily, respectively encapsulated, so that they can be replaced with each other. This pattern changes the algorithm and does not affect the customers who use the algorithm. Rule mode structure   Strategy:

Rule Mode: It definesAlgorithmFamily, respectively encapsulated, so that they can replace each other. This mode changes the algorithm and does not affect users who use the algorithm! Instance: 1. Create an abstract class strategy. Java

Reprinted from: http://blog.csdn.net/sh_c1991/article/details/45965743Our idea is to use Key's own class type as key. Because Class it is a parameterized type, it ensures that we make the context method type-safe without resorting to an unchecked

Design pattern (Patterns)--the foundation of reusable object-oriented software Design patterns are a set of repeated use, most people know, through the classification of purpose, code design experience Summary. Design patterns are used in order to

First, the intentionDefine a series of algorithms, encapsulate them one by one, and make them interchangeable with each other. The policy pattern allows the algorithm to change independently of the customers who use itThe strategy pattern changes is
