registered, back Group is notify) 2, there is a better understanding, when one thing is done, you can do other things. such as: With Money can buy food, wear, drink. (One-to-many). When you spend money in the bank will be, SMS notify you, email notify you, notify you, you can also cancel SMS notification. What are the points of note when using Observer mode? If there is a cyclic dependency between the observers, the observed will trigger a cyclic call between them, causing the system to crash.

functions, because different observers have different ways, so declare them as pure virtual functions, implemented in derived classes.3. The observer is implemented with the list template in Std, so a destructor is required to release it.Viewer Interface Description:1. Because all observers have an update status, declare it as an interface.The 2.Update () function has different behavior for different concrete objects, so it is implemented in derived classes and declared as pure virtual function

hang a QQ on the computer, and then hang one on the phone, when we receive a friend message, our mobile phone and QQ on the computer will also receive the same message notification, which is actually the typical use of the observer pattern, at this time the message is an observer of the notification event, And the mobile phone and the computer side is an observer object, of course, the situation here is slightly more complex, need to match the message sender and receiver of the object, decide w

For each Winsock service, the following information is displayed: Display name, enable/disable state, DLL type (32-bit or 64-bit), and creation/modification time. Winsockservicesview also allows you to easily disable/enable a Winsock service provider.Picture preview::http://dickmoore.cn/Down/winsockservicesview.zipWinsockservicesview (Sock Service

The observer pattern in 23 kinds of software design patterns is also a kind of design pattern used in software development. In Apple development, the Apple Cocoa Framework has implemented this design pattern for us, that is, notification and KVO (Key-value observing), this post will first explain the common methods of notification and KVO and use examples, and then explain the observer pattern and the implementation of the Observer pattern, Finally, a self-fulfilling cocoa framework kvo.Article

So that the database of a application is changed.This mechanism is similar
