ComponentFactory取得DOM节点

取得DOM节点：
ComponentFactoryResolver.resolveComponentFactory.create.location.nativeElement

class ComponentFactoryResolver {
  static NULL: ComponentFactoryResolver
  resolveComponentFactory<T>(component: Type<T>):ComponentFactory<T>
}

class ComponentFactory<C> {
  get selector(): string
  get componentType(): Type<any>
  get ngContentSelectors(): string[]
  get inputs(): {propName: string, templateName: string}[]
  get outputs(): {propName: string, templateName: string}[]
  create(injector: Injector, projectableNodes?: any[][], rootSelectorOrNode?: string|any, ngModule?: NgModuleRef<any>): ComponentRef<C>
}

class ComponentRef<C> {
  get location(): ElementRef
  get injector(): Injector
  get instance(): C
  get hostView(): ViewRef
  get changeDetectorRef(): ChangeDetectorRef
  get componentType(): Type<any>
  destroy(): void
  onDestroy(callback: Function): void
}

class ElementRef {
  nativeElement: any
}
