I have a class using generics like such -
export class MyClass<T>
{
constructor( private myCallback:()=>T)
{
...
}
}
My callback is a lambda fucntion that returns a new object of type T. I'd like to be able to write code inside MyClass as such
let t:T = this.myCallback() ;
however i'm running into build errors. Seems the syntax is broken somewhere but i don't know where. Can anyone help?
The following compiles just fine here :
class MyClass<T> {
constructor(private myCallback: () => T) {}
thing(): T {
const t: T = this.myCallback();
return t;
}
}
let s: string = new MyClass<string>(() => "hello").thing();
