I have a class: BaseResourceModel on my Angular application

export abstract class BaseResourceModel{
    id?: any;
    description?: string;
    name?: string;
}

And several other classes inheriting from it like this:

import { BaseResourceModel } from '@core/models/_base/base-resource.model';

export class CityModel extends BaseResourceModel{

    constructor(ufId?: number){
        super();
    }

    static factory(obj: any): CityModel{
        return Object.assign(new CityModel(), obj);
    }
}

I would like to know if there's a way or a proper way to put the static factory method on the BaseResourceModel, but specifying for each heir the type of assignment, like this:

export abstract class BaseResourceModel{
    id?: any;
    description?: string;
    name?: string;

    static factory(obj, class){
        //ex.: class parameter will get here like CityModel
        return Object.assign(new class(), obj);
    }

}
