file_control_value_accesor.ts

import {Directive, forwardRef, Provider} from "angular2/core";
import {NG_VALUE_ACCESSOR, ControlValueAccessor} from "angular2/common";
import {CONST_EXPR} from "angular2/src/facade/lang";

const FILE_VALUE_ACCESSOR = CONST_EXPR(
    new Provider(NG_VALUE_ACCESSOR, {useExisting: forwardRef(() => FileControlValueAccessor), multi: true})
);

/**
 * The accessor for listening to changes that is used by the
 * {@link NgModel}, {@link NgFormControl}, and {@link NgControlName} directives.
 *
 *  ### Example
 *  ```
 *  <input type="file" [(ngModel)]="video">
 *  ```
 */
@Directive(
    {
        selector: 'input[type=file][ngControl],input[type=file][ngFormControl],input[type=file][ngModel]',
        host: {'(change)': 'onChange($event.target.files)', '(blur)': 'onTouched()'},
        bindings: [FILE_VALUE_ACCESSOR]
    }
)
export class FileControlValueAccessor implements ControlValueAccessor {
    onChange = (_: any) => {};
    onTouched = () => {};

    writeValue(value: any): void {
    }

    registerOnChange(fn: () => any): void {
        this.onChange = fn;
    }

    registerOnTouched(fn: () => any): void {
        this.onTouched = fn;
    }
}

How would these import statements be written with the latest version of Angular? (i.e. @angular/core and @angular/common don't work)

Thanks
