definitions, and Spring AOP is the framework responsible for implementing facets that weave the crosscutting logic defined by the facets into the connection points specified in the facets.The focus of AOP is on how to apply the enhancement to the connection point of the target object. This includes two jobs:1. How to locate the connection point by tangency and enhancement.2, how to write the cross-cutting logic code in the enhancement.This series of essays will focus on breaking the above two p

Since the single-point process sequence diagram in the previous article was directly downloaded from the official website, it was in English and may not be understood by some friends, so it was changed to Chinese.
result class, which is a proxy class that incorporates the original class and the pre-increment logic . Depending on the proxy method. The proxy class may be a class with the same interface as the original class, or it may be a subclass of the original class. So we can invoke the proxy class in the same way we call the original class.8. Slice (Aspect)Facets consist of tangency and enhancement (introduction), which contains both the definition of the crosscutting logic and the definition of the

Class
Class is the code segment used to create an object as a design blueprint. It describes the features of an object, the attributes of the object, the tasks of using the object, and the responses of the event!
Object
An object is an instance of a class. It is usually created by calling a constructor of the class!
Method
A method is a function defined in a class. Generally, a method d

platform based on Linux,apache,mysql and PHP, a programming language that is sometimes replaced by Perl or Python. The term comes from Europe, where these programs are often used to assemble sometimes as a standard development environment. The name comes from the first letter of each program. Each program in ownership is compliant with open resource standards: Linux is an open system; Apache is the most common Web server; MySQL is a relational database with Web-based management add-ons; PHP is
Iterator (Iterator) mode, also known as cursor mode. GOF provides a way to access individual elements of a container (container) object without exposing the object's internal details. The iterator pattern is visible from the definition and is for the container. Obviously, access to the container object inevitably involves a traversal algorithm. You can plug the Traversal method into the container object in a single brain, or not provide any traversal algorithms at all, so that the person who use

If you pass an object to you, you can find out what it is capable of, which is a powerful feature. If Python does not support some form of introspection, the Dir and type built-in functions will be difficult to work properl

After the client is reached, if the interface is displayed with this object, then its identity will be converted to VO.O/R Mapper object/relationship Mapp

(object): An object is an instance of a user-defined type (a class type) (a data item). The difference between an object and a variable is that the variable retains state information and the object can have behavior(? )。 Here, an object refers to an instance of a user-defined type, whereas a variable is an instance of a primitive type. In the case where both object and variable are applicable, object is used as an inclusive term that represents "objects and variables."scope (SCOPE): Names can o

Provides interfaces for the business layer. This object is used to access the database. Usually used in conjunction with PO, DAO contains various methods of operation of the database. Combine PO to perform related operations on the database. Sandwiched between business logic and database resources. With VO, provid

When the CI framework was first used, it was intended to write a series of CI-source reading notes, which, unfortunately, had not been acted on. Recently there are few projects, and finally there is some time to write something. Then prepare to record some of the previous notes and experience, on the one hand, the right to make a memo, on the other hand remind yourself: learn from learning and have a way out, forget the past means betrayal! Basic Terminology
We will encounter a lot of relevant terminology in setting up the U disk startup process, and here are some common:
BIOS (Basic input/output System)
The basic input and output system, the full name is Rom-bios, is read-only memory basic input/output system shorthand, it is actually a group of curing to the computer, to provide the lowest level of the most direct hardware control program.
CMOS (complementary Metal oxide semiconductor)
