如何获取 .kt 文件中所有类的列表

Question

Is it possible to grab a list of classes inside a .kt file? It appears that KDeclarationContainer is the class I am looking for, but I am unsure of how to use it.

EDIT: I am using Kotlin Reflection.

Answer 1

It's not possible to obtain all classes which were declared in a specific .kt source file at runtime via reflection API, in much the same way as it's impossible to get all Java classes in a .java source file with Java reflection API. This information is simply not available at runtime.

What is your use case? I think if you're relying on something like that, your best workaround is to declare your classes inside one top-level class, and call KClass#nestedClasses to get them all at runtime.
