So i have a function that takes a generic and a parameter. This generic is not an instance, but a typename. I need to call a static method of the class corrensponding to the typename.

public <T extends Base> void Process(Callback functionInterface)
{
  functionInterface.call(T.GetStaticParams());
}

I know that all possible T classes have a static method GetStaticParams(), but the Java compiler does not know how to find the function specified.

I have tried having GetStaticParams() in Base and all Children classes, but then only the method in the Base class gets called.

You need to also pass `Class` and invoke the static method via reflection. – EpicPandaForce Dec 03 '19 at 17:33

I don't think this is possible due to type erasure. – alci Dec 03 '19 at 17:33
What's the problem you're solving with this? Seems roundabout – Rogue Dec 03 '19 at 17:35
