observer interface. A specific observer contains a topic interface variable that can be referenced by a specific topic, so that a specific observer can add his/her reference to a specific topic set and make himself/herself an observer, you can also delete a topic from its collection so that it is no longer its observer. In the example of the previous part-time center, the part-time center is a specific topic. It can update various part-time information and notify its members. Of course, it can

The observer pattern of Java and patternsIn the book "Java and Patterns" of Dr. Shanhong, this describes the Observer (Observer) pattern: The Observer pattern is the behavior pattern of the object, also called the Publish-subscribe (publish/subscribe) mode, the Model-view (Model/view) mode, the source-listener (Source/listener) mode, or the slave (dependents) mode.The Observer pattern defines a one-to-many dependency that allows multiple observer objects to listen to a

Project requirements:Source codeAfter some understanding, record it, so that you can easily find ideas in the future.
First, we need to understand the requirements that CAs uses to meet. CAS needs to provide two protocols, cas1.0 and 2.0. This is illustrated at http://www.jasig.org/cas/protocol, but it is not very rational. The CAS client. Net version is very refined. (Http://www.middleware.vt.edu/doku.php?

I. Intention
Defines a one-to-many dependency between objects, and when the state of an object changes, all objects that depend on it are notified and automatically updated.
Second, applicability
The design pattern mentions that observer mode can be used in any of the following situations:
1. When an abstract model has two aspects, one aspect relies on the other. Encapsulate the two in separate objects so that they can be changed and reused independently of each other.
2. When a change to
