示例1: create

  normalizedName?: string;
  create(props?: { [prop: string]: any }): T;
}

export interface Owner {
  lookup<T>(fullName: string, options?: LookupOptions): T;
  lookup(fullName: string, options?: LookupOptions): any;
  factoryFor<T, C>(fullName: string, options?: LookupOptions): Factory<T, C> | undefined;
  factoryFor(fullName: string, options?: LookupOptions): Factory<any, any> | undefined;
  buildChildEngineInstance<T>(name: string): T;
  hasRegistration(name: string, options?: LookupOptions): boolean;
}

import { symbol } from 'ember-utils';

export const OWNER = symbol('OWNER');

/**
  Framework objects in an Ember application (components, services, routes, etc.)
  are created via a factory and dependency injection system. Each of these
  objects is the responsibility of an "owner", which handled its
  instantiation and manages its lifetime.

  `getOwner` fetches the owner object responsible for an instance. This can
  be used to lookup or resolve other class instances, or register new factories
  into the owner.

  For example, this component dynamically looks up a service based on the
  `audioType` passed as an attribute:

  ```app/components/play-audio.js
