If you miss the article, mayb

In complex association operations, if you want to add optional attributes to the association definition, we can take a fully defined approach. The fully defined format is: protected $_link = Array (' Associative table name 1 ' = = Array (' The table is associated with the property 1 ' = ' = ' = ' = ' = ' = ' = ', ' The table is associated with the property n ' = ') Define ', '), ' Association table name 2 ' = = Array (' The table is associated with a

1. Defining variables can cause construction and destruction overheadWhenever you define a variable of a type: when the control flow reaches the defined point of the variable, you introduce the overhead of calling the constructor, and when you leave the scope of the variable, you introduce the overhead of calling the destructor. There is also a cost to unused variables, so avoid this definition as much as possible.2. The variable definitions in the no

Ask a question:Consider a template:Template There are several ways to define the following. What is right (by compiling)? Template In order not to affect the analysis of inference, I put the answer color into a lighter color, the following is the answer: Template Template Template Template Template Template Question Answer:First, explain the three correct answers.The first form is called the definition of specif

be like this: man. BestFriend. Name. Why can't we let ourselves define the data structure in the most efficient way? This is what we need to talk about in this article, but I am not thinking deeply. So I hope you can come and talk with me. Generally, an application can be divided into at least three layers: interface layer, business layer, and data layer. Our current object definition is basically only considered at the data layer, that is, the objec

when you create a process, you often use the type definition of the process number: pid_t. We all know that this type definition is actually an int type. But how is this definition defined in the header file in C under Linux? Today, the process of finding this definition has been posted:1. First, the following definiti

Precompilation is the first step in the entire compilation process and is the result of the g++-e option output. This step deals with the macros in the source file/header file, which are commonly used in the following categories: file contains: #include macro definition: #define, #undef conditional compilation: #ifdef, #ifndef, #if, #elif, #else, #endif, 1. file contains #include Preprocessing will include the contents of the file to be included, such

Referenced from SQL Server internals“As views, these metadata objects is based on an underlying Transact-SQL (T-SQL) defnition. The most straightforward-of-the-defnition of these views are by using the Object_defnition function. (You can also see the defnition of these system views by using sp_helptext or by selecting from the catalog view Sys.syste M_sql_modules.) The defnition of Sys.tables, you can execute the following:SELECT object_definition (object_id (' sys.tables '));”Method One:Object_

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.
