Is there a way to tell if a class is an instance of a Kotlin interface without doing a cast? Basically I have a class that I load from an external jar using URLClassLoader.loadClass(). The only way I can figure if it's an instance of the interface is I then create an instance of the class and try to cast it. So basically val testClass = urlClassLoader.loadClass("some-class").newInstance() as? InterfaceClassName If testClass is null then I assume it wasn't an instance of that interface. Any easier way? Thanks!
