One. Observer mode: (1). Observer pattern Definition: defines a one-to-many dependency that allows multiple observers to listen to a Principal object. When the Subject object changes, all the observer objects are notified, allowing them to update themselves automatically. (2). The composition of the Observer pattern:a). Specific topic role: Notifies all registered observers when changes occur within a specific subject role. (typically implemented with a class)b). Abstract theme Role: Save refe

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
