have an attribute: A,b,c,d,e,f. Suppose that the relationship has a function dependent on f={ab->c, Bc->ad, d->e,cf->b}, to determine whether Ab->d,d->a is contained in these function dependencies.Solution: The former translates to the closure of attribute set AB: {A,b,c,d,e},d is a subset of its closures, so the former is contained in these function dependencies. The latter asks for the closure of attribute set D: {D,e},a is not a subset of its closures, so the latter does not contain it.

First, Ngui default multi-resolution adaptation principleThe Ngui itself is based on the principle of "highly adaptable" for UI adaptation at multiple resolutions, and its default height is set by Uiroot.manualheight. With the use of uianchor, a certain degree of multi-resolution adaptation can be achieved.Where the UI page is edited under Unity Editor in accordance with the height set by uiroot.manualheight. This way, when the UI page is displayed on the target device, Ngui adjusts the scale of

What is AOP?AOP (aspect-oriented programming, aspect-oriented programming) can be said to complement and improve OOP (object-oriented programing, object-oriented programming). OOP introduces concepts such as encapsulation, inheritance, and polymorphism to create an object hierarchy that simulates a collection of public behavior. When we need to introduce public behavior to scattered objects, oop seems power

Question: What is AOP?A: The basic concept of AOP: aspect-oriented programming, the abbreviation for aspect-oriented programming, Aspect is a new modular mechanism. To describe the crosscutting concerns (crosscutting concern) scattered in objects, classes, or methods, the separation of crosscutting concerns from concerns is the core of

AOP (Aspect-Oriented Programming) can be said to be a supplement and improvement of OOP (object-oriented programing, object-oriented programming. Oop introduces concepts such as encapsulation, inheritance, and Polymorphism to establish an object hierarchy to simulate a set of public behaviors. When we need to introduce public behavior to scattered objects, oop seems powerless. That is to say, oop allows you to define the relationship from top to botto

Implementation principle of Spring AOP (ii) use Spring AOP Like AspectJ, Spring AOP also needs to enhance the target class, that is, to generate a new AOP proxy class. Unlike AspectJ, Spring AOP does not need to use any special The command is used to compile the Java source code. It dynamically generates a "proxy class" in the memory at runtime to generate the AOP proxy. Spring allows the use of AspectJ Annotation for defining (Aspect), Pointcut, and

As with AspectJ, spring AOP also needs to enhance the target class, which is to generate a new AOP proxy class; unlike AspectJ, Spring AOP No need to use any specialcommand to compile the Java source code, which takes the runtime to generate an AOP proxy in a way that dynamically and temporarily generates "proxy classes" in memory.Spring allows the use of AspectJ Annotation for defining facets (Aspect), pointcuts (Pointcut), and enhanced Processing (A

AOP is the continuation of OOP and is the abbreviation for Aspect oriented programming, meaning aspect-oriented programming. A technology that can dynamically and uniformly add functionality to a program without modifying source code is possible through precompilation and run-time dynamic proxies.
