I tried with this but it doesn't work. Foo is just a test of what works. Bar is the real try, it should receive any newable type but subclasses of Object isn't valid for that purpose.
class A {
}
class B {
public Foo(newable: typeof A):void {
}
public Bar(newable: typeof Object):void {
}
}
var b = new B();
b.Foo(A);
b.Bar(A); // <- error here
You can use { new(...args: any[]): any; } to allow any object with a constructor with any arguments.
class A {
}
class B {
public Foo(newable: typeof A):void {
}
public Bar(newable: { new(...args: any[]): any; }):void {
}
}
var b = new B();
b.Foo(A);
b.Bar(A); // no error
b.Bar({}); // error
