Interpretation of source code based on Annotation configuration Bean Definition
The first part of this series analyzes the source code of the
Annotation-based Bean parsing portal
As shown in Figure 2 above, the last Loop sequence diagram in the lower-right corner is the entry for the parse Bean for the Annotation configuration, so its detailed steps refer to the analysis in Figure 2 above. XML Context N
This article mainly introduces the module definition and module Loading Analysis of seaJs, as well as the dependencies between modules, for more information, see SeaJS, a module loading framework developed by yuber that complies with CommonJS specifications. It can be used to easily load arbitrary JavaScript modules and css module styles. SeaJS is very small and small. It is only 4 kb after compression and
is a language structure. and define is a function. So it's much faster to use the const.
Naming conventions for constants:Constants contain numeric alphabetic characters and underscores, numbers are allowed as constant namesUse uppercase words and underline spacing, for example embed_suppress_embed_exception but don't do this embed_suppressembedexceptionIt is usually prefixed with the package name of the constant or the class title. For example, constants in a bug class should start
Inside the memory.c. A macro definition is encountered, such as the following:#define CODE_SPACE (Addr) ((((addr) +4095) ~4095) Look at the first glance, don't know. Second glance. Still don't know. Tangled up half a day still do not know.Sleep one night, see again this morning, hey, unexpectedly read ...This macro definition is used to infer whether a given addr linear address is in the code snippet of the
Python Binary Tree definition and common traversal algorithm analysis, python Binary Tree
This example describes the definition of a Python binary tree and common Traversal Algorithms. We will share this with you for your reference. The details are as follows:
Speaking of binary tree traversal, the university talks about recursive algorithms. Most people first th
Sscanf definition, usage, and analysis: the sscanf () function parses input from a string based on the specified format. if only two parameters are passed to the function, the data will be returned in the form of an array. Otherwise, if additional parameters are passed, the parsed data will be stored...

This article mainly gives you a detailed analysis of JavaScript function definitions. For more information, see
Function
Key points:
A). functions are first-class citizens (importance) in javascript)B). A function is an object.C). The function defines an independent variable scope.
Definition Method
A) Name function:
Unless defined in another function, the name function is global.
// Global name function
.
Next, let's look at the 3rd lines of the above Code. here we need to describe offsetof, which is defined in include/Linux/stddef. H. Its definition is as follows:
1. 24 # define offsetof (type, member) (size_t) (type *) 0)-> Member)
Similarly, we expand the above offsetof call, that is:
1. (struct demo_struct *) (char *) _ mptr-(size_t) (struct demo_struct *) 0)-> member3 ));
It can be seen that the implementation principle of offsetof is to take

This example describes the definition of a method in the go language. Share to everyone for your reference. The specific analysis is as follows:
In fact, you can define arbitrary methods for any type in the package, not just the struct body.Methods cannot be defined on types or underlying types that come from other packages.
Copy Code code as follows:
Package Main
Import (
"FMT"
"Math"
)
Type
This example describes the method of defining constants in the Go language. Share to everyone for your reference. The specific analysis is as follows:
The definition of a constant is similar to a variable, except that it uses the Const keyword.
Constants can be values of a character, String, Boolean, or numeric type.
Copy Code code as follows:
Package Main
Import "FMT"
Const PI = 3.14
