问题描述
是否可以创建一个实现以下接口的对象:
Is it possible create an object that implements the following interface:
interface I {
(): string;
new(): any;
}
我看到可以实现具有调用签名和来自这个问题的一些字段的接口:使用裸函数签名和其他字段实现 TypeScript 接口
I saw that it is possible to implement an interface having a call signature and some fields from this question: Implementing TypeScript interface with bare function signature plus other fields
推荐答案
环顾四周,很明显一个对象可以同时实现具有构造函数签名和调用签名的接口:
After looking around, it is clearly possible for an object to implement the an interface with both a constructor signature and a call signature:
https://github.com/Microsoft/TypeScript/blob/master/lib/lib.d.ts#L142 就是一个例子.
底层函数似乎是相同的,尽管以两种不同的方式调用:
The underlying function seems to be the same, albeit called in two different ways:
new Object(3);
和
Object(3);
这篇关于TypeScript:使用调用签名和构造函数签名实现接口的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
