1. 反射(Reflection)在编程中的概念 反射是编程中的一个概念,它允许程序在运行时检查、修改其结构和行为。具体来说,反射可以访问类的元数据(如类的成员变量、方法、构造函数等),并可以动态地创建对象、调用方法、访问和修改字段等。这种能力使得编程更加灵活和动态。 2. TypeScript中反射的用途和场景 TypeScript,作...
T extends object: Enables precise type control through reflection class methods and properties. Defined by the constructor parameter object. Types references: PropertyType: Represents any single property type, either primitive or complex. PropertyTypes: A mapping of property names to their types. Type...
typescriptreflectioninterface 10 有没有一种方法可以查找接口的属性是否被定义为只读?例如, interface ITest { readonly foo: number; } 现在,对于TypeScript来说是否存在某种反射或技巧来获取这些信息?例如: let info = Reflect.get(ITest, 'foo'); if (info.isReadOnly()) { ... } ...
Hint TypeScript's metadata reflection system has several limitations which make it impossible, for instance, to determine what properties a class consists of or recognize whether a given property is optional or required. Because of these limitations, we must either explicitly use the @Field() decor...
Reflection OOP programmers are accustomed to being able to query the type of any value, even a generic one: // C# static void LogType<T>() { Console.WriteLine(typeof(T).Name); } Because TypeScript’s type system is fully erased, information about e.g. the instantiation of a generic ...

Other component properties and methodsFirst we declare a component:// MyModule.ts const {ccclass, property} = cc._decorator; @ccclass export class MyModule extends cc.Component { @property (cc.String) myName: string = ""; @property (cc.Node) myNode: cc.Node = null; } And import My...
