Consider the following code, where I’m trying to override and also specify the parameter passed to a generic class method:

   class MyBaseClass {
       getData<T extends MyBaseClass>(classes: {[key: string]: T}){}
    }
    
    
    class FirstChild extends MyBaseClass {
       private data: number[];
    
       constructor(){ data = [//get data]}
    }
    
    // e.g. 1
    class SecondChild extends MyBaseClass {
         private data: number[];

         getData<FirstChild>(classes: {category: FirstChild}){} // error
    }

now, this gives an error and for it to be error free, I’m gonna have to change SecondChild to:

  class SecondChild extends MyBaseClass {
             getData(classes: {[key: string]: FirstChild}){} // error
        }

I’m wondering if something similar to my first example (e.g.1) is possible. What I want is to generalize the base class but, specify the elements that I pass to the child class.

For example, if it were possible I could get specific keys for extended entities while not worrying about them in parent. E.g. 2:

class ThirdChild extends MyBaseClass {
         getData(classes: {category1: FirstChild}, category2: SecondChild){
            const categoryAData = category1.getData(),
            const categoryBData = category2.getData(),

       } 
    }

Is there a way to somehow achieve this?
