[英]Interface field should have type of the class that implements that interface - typescript
I am wondering if this is achievable in Typescript. 我想知道这在Typescript中是否可以实现。
interface Pine {
child : <The class that implements this interface>
}
class Vine implements Pine {
child : Vine // this is enforced to be Vine, rather than any object that implements Pine.
}
I know from this question that you cannot do it in Java, but what about TS? 从这个问题中我知道您无法用Java做到这一点,但是TS呢? I have looked up tslang doc without fruition.
我查了一下tslang doc却没有结果。
You can use Generics. 您可以使用泛型。 eg :
例如:
interface Base<T> {
child: T;
}
class Derived implements Base<string> {
child: string;
}
class Derived2 implements Base<number> {
child: number;
}
