javascript - Add a decorator with parameters to an abstract class that requires data from the instantiated class (typescript)

Question

I am trying to add a decorator to an abstract class but the decorator requires a value given when the class is instantiated. Here is an example:

export abstract class AbstractClass {
    abstract dataNeededFromChild: string;

    abstract implementedOnChildClass(): boolean; // the class instantiated on the child

    @someDecorator(this.dataNeededFromChild) // here is the problem, the decorator needs data from the instantiated class
    _implementedOnChildClassWrapper?(): boolean {
        return implementedOnChildClass()
    }
}

The problem is that no matter what I do the best result have been a method with an empty argument on the decorator. The data from the child is not reaching the decorator on the abstract class.
