For Java, most of the abstract factory patterns you can see are as follows:There are a bunch of factory methods in it, and each factory method returns some type of object.
For example, the factory can produce mouse and keyboard. So the abstract factory implementation class (a specific subclass of it) objects can produce the mouse and keyboard, but Factory A may produce the Logitech keyboard and mouse, factory B is from Microsoft.
In this way, A and B

The sound is not pre-recorded, but determined based on your control. Real-time interactive sound requirements for input devices are stronger than those for sound recording devices (for example, movies.1.

Dolby is a British R. m. dr. Dolby's Chinese interpreter, who has established the Dolby laboratory in the United States, has successively invented many technologies such as the Dolby noise reduction system and the Dolby surround sound system, which have a huge impact on movie and home audio. The commonly used Dolby technologies in the family mainly include Dolby noise reduction systems and Dolby surround so
In d3d10/11, there is the d3d10_query/d3d11_query interface. Through the query interface, we can query Some GPU statuses, such as timestamp) [This is often used for performance analysis], or to block query information.

way to declare AOP - * 1. Use @aspect annotations to declare a class as a slice (if you annotate a bean object with a @component ("") annotation, you must turn on the annotation scan in the spring configuration file + * Otherwise declare a Bean object in the Spring configuration file) - * 2. Add the appropriate comment before the slice needs to implement the corresponding method, that is, the notification type. + * 3. There is a surround notificati
the Cglib proxy. Implement the proxy for the class, not the interface. If the business object does not implement an interface, the Cglib proxy is used by default. But interface-oriented programming is a good habit, try not to target specific classes of programming. Therefore, a business object should typically implement one or more interfaces. 7, target object: An object that contains a connection point, also known as a proxy object. 8, pre-notification (before advice): A notification that

Joinpoint (Connection point): The so-called connection point refers to the points that are intercepted. In spring, these points refer to methods because spring only supports connection points of method types.
Pointcut (pointcut): The so-called pointcut is the definition of which joinpoint we want to intercept.

mainly used for proxy interfaces. You can also use the CGLIB proxy. The proxy of the implementation class, not the interface. If the business object does not implement interfaces, CGLIB proxy is used by default. But interface-oriented programming is a good habit. do not apply to specific classes as much as possible. Therefore, a business object must implement one or more interfaces.
