In the introduction to the spring IOC container launch, a rough analysis of the launch process of the IOC container was made on the basis of Classpathxmlapplicationcontext, with no detailed description of some of the more complex steps, This article begins with some of the more complex steps that are analyzed. This article analyzes the parsing and loading process of the bean definition of the IOC container based on the Classpathxmlapplicationcontext.

development of function declarations 1 implicit function Declaration implicit function declarationThe main function and the printf function return value type int, if not declared, the compiler default function return value is the INT type C90 standard, this kind of writing enters the process which is gradually discarded (although it was not abolished completely immediately) C99 abolished the implicit function declaration law (remove impli CIT function declaration), omitting the int in front of

Replace macros with inline: 1. Inline functions can be debugged at run time, while macro definitions are not possible;2. The compiler will do security checks or automatic type conversions (with normal functions) on the parameter types of the function, while the macro definition will not;3. The inline function can access the member variables of the class, and the macro definition cannot;4. Declare a member

Macro definition can help us prevent errors and improve code portability and r

1. Rules and usage resolution for macro definitions(1) The parsing rule of a macro definition is that it is replaced by a preprocessor during the preprocessing phase, and the substitution is unchanged.(2) The macro definition substitution is performed recursively until the replaced value itself is no longer a macro.(3) A correct macro definition of the formula it

Differences between variable definition and Declaration (Reprinted) In program design, we always use the definition of variables and the declaration of variables. Sometimes we are not very clear about this concept and know how to use it, but I don't know how it will take for a while. Below I will simply introduce their differences as follows: There are two scenarios for variable declaration:(1) One is to cr

Macro Definition Learning (1) Macro names are generally capitalized(2) The use of macros can improve the universality and readability of the program, reduce inconsistencies, reduce input errors and facilitate modification. Example: array size common macro definitions(3) Preprocessing is the processing before compiling, and one of the tasks of compiling is grammar checking, preprocessing does not do grammar checking.(4) No semicolon at the end of

A macro definition is one of the pre-compilation features, pre-compilation, also known as preprocessing, is the preparatory work for the compilation phase. The instructions that handle the beginning of the #, such as the file code that the copy #include contains, #define宏定义的替换, conditional compilation, and so on.Benefits of using macro definitions: Benefits of using Macro definitions: Improves program versatility and readability, reduces inconsistenci

The difference between a variable's definition and a declarationFirst, the definition of a variable must occur before the variable declaration (extern), the declaration of a variable can have more than one, but the definition of the variable is only one, the declaration of the variable affects the reference and scope of the variable, and the

To understand the definition and execution of JavaScript functions, you need to know these important concepts first, and now you can understand them later!the execution environment of the function (Excution context), the active object (call object), scope (scope), scope chain (scope chain). Next, let's take this function as an example to analyze:Steps:1. Set the scope chainWhen you define function A, the JS interpreter willScope Chain (scope chain)Set

Like to read some Open-source project source, always will find that the great God's code always have some short and efficient macro definition, click to see, find obscure, not to mention learning, sometimes understanding is a difficult, but the macro definition itself is not so difficult, But write a good macro of course still need rich experience and technology, then say a macro

In Java, an array is considered an object When you define an array, there are two definitions: int[] A and int a[]; the second is a C + + array-defined method, with the first definition of Java recommendations. The general principle: any object must be initialized before being called. definition of 11-D arrays Defines a one-dimensional array that contains three elements //Method 1, first the new object, an

css| Project This tutorial mainly explains the definition of the style of common tags Li {list-style-image:url (images/disc.gif);} This style definition for Li is to use a picture for a list item instead of a small dot that is displayed. Of course, you can also display other effects, see the following definition in detail: 　　CSS
