The following are the rules for NGWS runtime when declaring, using, and managing type models in Vos.

The idea behind Vos is to build a framework that does not sacrifice performance when executing code, allowing for cross language integration and type safety.

the shipment is the product of the production department, since the manager can sell the product to the customer in the name of the plant, which is not the factory at all.Characteristics of the __new__ () method: The __new__ () method is called when the class prepares to instantiate itself. The __new__ () method is always a static method of the class, even if the static method adorner is not added. The instantiation of a class and how it is constructed are usually the same way:

Table can be used as a unique identifier to identify UserData, where metatable to determine if the correct UserData parameters are passed in.InheritanceInheritance in the COCOS2DX:function class (classname, ...) Local CLS = {__cname = classname} Local supers = {...} For _, Super in Ipairs (supers) do local supertype = Type (Super) assert (supertype = = "nil" or supertype = = "T Able "or supertype = =" function ", String.Format (" Class ()-Create c

process special applications.Simulate the instanceof OperatorAfter getting the class information, the next step is to solve some basic problems about the class object. For example, the class. isinstance method can be used to simulate the instanceof OPERATOR:Class {}Public class instance1 {Public static void main (string ARGs []) {Try {Class CLS = Class. forname ("");Boolean b1 = Cls. isinstance (New INTEGE

, virtual methods, and object lifetime. No matter which language we use, the class behavior is completely consistent, because CTS is used to define the class behavior. CTS defines five types: Class type Interface Type Structure Type Enumeration type Delegate type The preceding five types contain a large number of type members, namely the collection {constructor, destructor, static constructor, nested type, operator, method, attribute, indexer, field, and read-only field, constant, one of

, there is a file named "extern. lua ", which has the following code: --Create an class.function class(classname, super) local superType = type(super) local cls if superType ~= "function" and superType ~= "table" then superType = nil super = nil end if superType == "function" or (super and super.__ctype == 1) then -- inherited from native C++ Object cls = {}

A metadatabase is a template of a class. It performs behavior at the class level.The following uses metadata to implement the singleton design mode (design mode 9 adopts another method ): [Python] From warnings import *[Python]Class SingletonMeta (type ):_ Instance = None_ Mutex = threading. Lock ()Def _ init _ (cls, name, bases, dic ):Super (SingletonMeta, cls). _ init _ (name, bases, dic)

Beginner. NET will certainly have a series of questions, such as (the following for their own questions):1) what is. NET Framework, what does it contain?2) What is an assembly and how does it run in the CLR (Common language runtime)?3) C # and VB.net belong to the. NET platform, the fundamental connection and difference between them, and why the assemblies between them can call each other (if creating a new type of orientation. NET language, to follow what)?To understand the above questions, you

fact, the Python module is a natural singleton mode, because when the module is first imported, the. pyc file is generated, and when the second import, the. pyc file is loaded directly, and the module code is not executed again. So we just need to define the relevant functions and data in a module, we can get a singleton object.# Mysingle.pyclass Mysingle:def foo (self):PassSinleton = Mysingle ()Save the above code in the file mysingle.py, and then use:From Mysingle import SinletonSingleton.foo

provide this instance to the whole system on its own.In Python, we can implement a singleton pattern in a variety of ways: Using modules Use__new__ Using adorners (decorator) Using meta-classes (Metaclass) Using modulesIn fact, thePython module is a natural singleton pattern .Because the module generates a file the first time it is imported, the .pyc file is loaded directly when the second import, .pyc and the module code is not executed again. Therefore, we just need

So, we just need to define the relevant functions and data in a module, we can get a singleton object.# mysingleton.py class My_singleton (object): def foo (self): = My_singleton ()Use: from Mysingleton Import My_singleton my_singleton.foo ()Second, use__new__Th

The __new__ () function can only be used for modern classes that inherit from object.First look at the definition of the __new__ () method in the object class:classobject:@staticmethod# known case of __new__def__new__(cls,*more):# known special case of object.__new__""" T.__new__(S, ...) -> a new object with type S, a subtype of T """passObject defines the __new__ () method as a static method and requires at least one parameter
