接口上的Typescript typeof？ [英] Typescript typeof on an interface?

问题描述

我最近在打字稿中发现了typeof关键字，几乎可以节省一天的时间。我想将dojo ContentPane描述为接口：

I've recently discovered the typeof keyword in typescript and it almost saves the day. I want to describe a dojo ContentPane as an interface:

declare module dijit {

    module layout {

        interface ContentPane extends dijit._Widget, dijit._Container {
        }
    }
}

declare module "dijit/layout/ContentPane"
{
    var ContentPane: typeof dijit.layout.ContentPane;
    export = ContentPane;
}

但是很遗憾，我无法在接口上执行typeof。我必须改为将ContentPane描述为一个类，但由于打字稿无法实现多重继承（通过扩展），我必须这样做吗？

But unfortunately I cannot do a typeof on an interface. I must instead describe ContentPane as a class but since typescript doesn't implement multiple inheritence (via extends) I must do this?

declare module dijit {

    module layout
    {

        class ContentPane extends dijit._Widget
        implements dijit._Container
        {
            // how to avoid duplicating the _Container here?
            addChild(widget: _WidgetBase, insertIndex?: number): void;
            getIndexOfChild(child: _WidgetBase): number;
            hasChildren(): boolean;
            removeChild(widget: _WidgetBase): void;
            removeChild(widget: number): void;
        }
    }
}

declare module "dijit/layout/ContentPane"
{
    var ContentPane: typeof dijit.layout.ContentPane;
    export = ContentPane;
}

有没有一种替代方案，不需要我重复dijit的签名。 _容器？是否有关于为什么typeof SomeInterface无法正常工作的解释？

Is there an alternative which does not require me to duplicate the signature of dijit._Container? Is there an explanation as to why typeof SomeInterface does not work?

推荐答案

尚无法做到这一点（0.9.5 ）。请参见工作项。

It is not yet possible to do this (0.9.5). See workitem.
