PHP policy mode definition and usage example, php policy usage example
This document describes the definition and usage of PHP policy patterns. We will share this with you for your reference. The details are as follows:

The rule mode is the behavior mode of the obje

Looking at "C + + Design new thinking", found in the beginning of a large length of the introduction of the Strategy Model (policy), the strategy model is not a classic design pattern, but in fact, in our day-to-day development is essential. Policy, strategy, policy, the meaning here is that the complex function of the class as far as possible to split into a sin
implemented.There are four ways to create a policy:
Create a retention policy in the site set and apply it to all content types in the site set)
Create a storage policy for a content type defined in the top-level website (root web)
Create a storage policy for the content types applied in the document library and l

The following is a post I saw on the csdn forum, which involves the understanding of synchronization, wait (), notify (), and other concepts, I tried to analyze the wait () and Policy () methods based on some original replies and related concepts in think in Java. Thank you for your advice.
The problem is as follows:
File: // analyze this program and explain it. here we will focus on synchronized, wait (), notify. Thank you!Class threada{Public static
Context ):
1. The concretestrategy algorithm is required.
2. Maintain a strategy instance internally.
3. dynamically sets the specific implementation algorithm of strategy during runtime.
4. Interaction and data transmission with strategy.
Strategy ):
1. A public interface is defined. Different algorithms implement this interface in different ways. The context uses this interface to call different algorithms, which are generally implemented using interfaces or abstract classes.

In this paper, a simple example to illustrate the implementation of the C # Strategy model, shared for everyone to reference. The implementation method is as follows:In general, when there are multiple implementations of an action, you might consider using a policy mode when you need to choose a method to perform the action according to different circumstances.Abstract the action into an interface, such as

As an administrator, it is extremely important to develop a set of basic security configuration policies for all network devices of the Organization. To this end, I share the security policies of routers and switches in a certain organization with you:
Router Security Policy Example:
1. the user account cannot be configured on the vro.
2. The enable password command on the vro must be saved in a secure encr

of them with your own needs to customize the application from *. Template method is a basic concept of the application framework, which is usually hidden behind the (framework) by invoking a set of methods of the base class (some methods you may have already overridden) to drive the application. An important feature of the Template Method is that it is defined in the base class and cannot be changed by (derived classes). Sometimes it is a private method, but in fact it is often declared final.
