      class ReflectiveKey {
  static numberOfKeys: number
  static get(token: Object): ReflectiveKey
  constructor(token: Object, id: number)
  displayName: string
  token: Object
  id: number
}
    

说明

Keys have:

  • a system-wide unique id.
  • a token.

Key is used internally by ReflectiveInjectorbecause its system-wide unique id allows the injector to store created objects in a more efficient way.

Key should not be created directly. ReflectiveInjectorcreates keys automatically when resolving providers.
