After Contronoller is activated, asp.net mvc gets the name of the target action based on the current request context, and then parses the corresponding method and executes it. In the execution of the whole action method, the analysis of model metadata is a very important link. asp.net MVC model actually view model, which represents the final binding to the view o

Today I learned the big talk design model. The first chapter of the book describes the simple factory model, which is described in C, so after learning, I wrote the content in the book in the form of C ++ to deepen my learning impression. First, what is the "simple factory model" should be: Use a separate class to create an instance. Big talk design

WPF core object model-class diagram and parsing, wpf Object Model DispatcherObject is a base class. by inheriting this class, you can obtain the Dispatcher object that accesses the UI thread that creates the object. Through the Dispatcher object, you can merge the code segment into the UI thread for execution. DependencyObject is the core base class used to implement the dependency attribute mechanism. D

Analysis of JVM Memory Model and javajvm Model Based on Java Technology 1. JVM Memory Model The JVM specification divides the VM memory into heap, stack, method zone, local method stack, and program counter. The heap and method areas are the areas shared by threads. Local method stacks, stack memory, and program counters are exclusive to threads. 2. Stack Stack

IO multi-channel model -- select, IO model -- select1. Trigger of IO multiplexing Model First, we will introduce the concept of "Trigger" in an I/O multi-channel model: 1 # There are two modes of horizontal triggering and edge triggering in linux I/O multiplexing: 2 #3 # horizontal triggering: if the file descriptor is

MVC modelThe MVC model contains all the application logic (business logic, validation logic, data access logic), in addition to pure view and controller logic. With MVC, models can save and manipulate application data.Models folderThe Models folder contains classes that represent the application model.Take login verification as an example to create a AccountModels.cs file for the application security model.accountmodels contains logonmodel,Changepassw

Adding multiple inheritance to the C + + object Model As you can tell from single inheritance, only the virtual function table of the base class is expanded in the derived class. If it is multi-inheritance, then how to expand it?1) Each base class has its own virtual table. 2) the member functions of a subclass are placed in the table of the first base class. 3) in a memory layout, its parent class layout is ordered in order of declaration. 4

Correlation models are mainly used in multi-table operations, such asUser table, User_role table, role tableUser_role field: Uid,rid, which acts as an intermediate table, is responsible for saving the 1-to-many, many-to-many relationships between user and role.The correlation model is used when querying the user's data and all role data owned by the user through the UID.The result of the role becomes a new array, inserted into the result array of the

A DOM introductionD (document): A Web page document that can be understood to be loaded for the entire web;O (object): Can be understood as something like a Window object, you can call properties and methods, here is the document object;M (model): a tree structure that can be understood as a Web document;1. NodeWhen loading an HTML page, the Web browser generates a tree structure that represents the internal structure of the page;DOM constructs this n

The previous chapter describes EOM ( Enterprise Business Model ) It is of great significance in economics, enterprise operation, and enterprise informatization. Starting from today EOM From theoretical analysis EOM And the Analysis of Enterprise Informatization reality. We will follow EOM To analyze the current information situation of Chinese enterprises, so that everyone can gradually understand EOM The relationship with enter

Java Memory Model-final, java model-final Compared with the locks and volatile described earlier, the read and write operations on the final domain are more like common variable access. For final domains, the compiler and processor must follow two reordering rules: Below, we will illustrate these two rules through some exemplary code: Public class FinalExample {int I; // common variable final int j; // fina

Design Model-factory ModelStart with reality Remember what I mentioned earlierSimple factory Mode?It still needs to be used in the client (main ).AnimalFactory.getAnimale(0)To select the animal type, when the new animal type is addedAnimalFactoryTo modify the code, which is equivalentBackgroundModify.Now we need to solve the problem by removing the switch statement in the Factory and any judgment logic, and simply using inheritance or polymorphism on
