Methods

Optional onTargetBeforeInstance

onTargetBeforeInstance(classReflect: ClassReflect): Promise<void>

- Defined in src/lib/AbstractClassDecorator.ts:22
当被此装饰器装饰的类实例化前触发此方法为异步方法必须返回Promise 要在这个阶段给子ClassReflect添加好依赖关系，否则子ClassReflect无法得到依赖注入，使用 classReflect.provider.set() 来完成提供。

要获取到父ClassReflect提供的依赖，可以使用classReflect.parent来获取，不过先要检测 ClassReflect 是否存在 parent

Parameters
- classReflect: ClassReflect
Returns Promise<void>

Optional onTargetInstanced

onTargetInstanced<T>(classReflect: ClassReflect, instanceReflect: InstanceReflect<T>): void | Promise<void>

- Defined in src/lib/AbstractClassDecorator.ts:29
当被此装饰器装饰的类实例化后触发

Type parameters
- T: object
Parameters
- classReflect: ClassReflect
  
  当前类的类映射对象
- instanceReflect: InstanceReflect<T>
  
  类实例化后的实例反射对象
Returns void | Promise<void>

Static create

create<P, T>(IDecorator: ClassDecoratorConstructor<P> & T): DecoratorFactory<P, ClassDecorator, T>

- Defined in src/lib/AbstractClassDecorator.ts:31
Type parameters
- P: any[]
- T: ClassDecoratorConstructor<P>
Parameters
- IDecorator: ClassDecoratorConstructor<P> & T
Returns DecoratorFactory<P, ClassDecorator, T>

Static defineMetadata

defineMetadata<T, M>(target: T, metadata: M): void

- Defined in src/lib/AbstractClassDecorator.ts:55
定义类装饰器元数据

Type parameters
- T: Object
- M: AbstractClassDecorator
Parameters
- target: T
- metadata: M
Returns void

Static getMetadata

getMetadata<T>(target: T): ClassSet<AbstractClassDecorator> | undefined

- Defined in src/lib/AbstractClassDecorator.ts:67
获取类装饰器元数据

Type parameters
- T: Object
Parameters
- target: T
Returns ClassSet<AbstractClassDecorator> | undefined
