I wonder if there was a way to add a parent class to another class i cannot control via reflection, I have some generated code I cannot change

[diesieben07]

Reflection can't change the code, it can only introspect it.

👍

Why do you need to add a parent class? To have a function? A field? Just go with extension functions

[coder82]

that's really complita to explain

[coder82]

but in my case i just solved the complexity by avoiding it

[coder82]

so i don't have to worry about it anymore

I’m curious.
a) What did you want to achieve by giving a library class a new parent
b) What did you do instead
🙂

[coder82]

i am using the openapi generator, generating code out of the API yaml and which calls the over HTTP

[coder82]

i generated 2 language clients, kotlin and java

[coder82]

these classes are generated as they are, and you can't change how they are generated without changeing the mustache templating or customizing the generator entirely

[coder82]

so you have 2 classes with same methods but they are not deriving from any other class

[coder82]

so adding an Interface at runing would have allowed me to use a strategy pattern and test them easily

[coder82]

because then I can implement 1 test method, and pass both the classes into into it if they implemented the same interface, problem is they don't, and I cannot add it at runtime... (this is what I wanted to do)

[coder82]

if you are curious I can show you the whole code and you see I have to test them separately with two test methods which look very similar yet i cannot use 1 and pass a different class, here it is:

PetApi both kotlin and java, implement the same API methods which I would need to call

[coder82]

for example in this case I call getPetById

[coder82]

that is some code which load tests the API which has to respond with 429 or some related message everytime it get's overloaded

[coder82]

so I bombard it with a bunch of requests

[coder82]

it's a kind of catch 22 situation, I wanted to simplify it so that I don't have to write twice the code all the time I want to test a call, no luck...

[coder82]

an alternative is to change the generator to add an interface on these 2 classes so that I can pass both with strategy pattern but it's way more complex to do that.

[coder82]

ah sorry

[coder82]

well I finished now
