Question

Hi I have class hierarchy like ```abstract class BaseClass lt TypeParam gt abstract class IntermediateClass lt TypeParam gt BaseClass lt TypeParam gt MyAnnotation class MyClass IntermediateClass lt String gt abstract class AnotherIntermediateClass BaseClass lt Int gt MyAnnotation class AnotherMyClass AnotherIntermediateClass``` All classes having ` MyAnnotation` are extending `BaseClass` in one way or another Can t figure out how to get the types parametrizing `BaseClass` for `MyClass` and `AnotherMyClass` can someone help me here please

In other words given that some type extends `BaseClass` I wan t to know what is the exact value of the type parameter in `BaseClass` despite of the class hierarchy

Vladimir Tagakov · Answer

As an other option I can add a method to the base class like ```abstract class BaseClass lt TypeParam gt fun dummy param TypeParam ``` then I can get the KSFunction and using `asMemberOf` with my `MyClass` or `AnotherMyClass` I can compute the parameter s value String and Int respectively The question is is it possible to achieve the same behavior without adding additional function to the `BaseClass` Looks like there is no way to do it in KSP

you should be able to get the value of type parameter from `KSTypeArgument`

Vladimir Tagakov · Answer

No with a code like this ``` myClass superTypes first returns IntermediateClass lt String gt 1 resolve 2 declaration as KSClassDeclaration superTypes first returns BaseClass lt TypeParam gt 3 resolve arguments first returns INVARIANT TypeParam not a INVARIANT String ``` I can get what you are saying at the ` 2 ` but at ` 3 ` the information is already gone Basically I am looking for the API similar to `fun KSClassDeclaration asMemberOfClassHierarchy containing KSType KSType` So I will be able to do something like ```resolver getClassDeclarationByName com BaseClass asMemberOfClassHierarchy myClassKSType arguments should have KSTypeArgument with INVARIANT String ```
