Interface equivalent for getClassesImplementing()? #924
Description
I can use getClassesImplementing(interface) to easily retrieve all classes implementing a given interface. However, there is no equivalent for getting all classes and interfaces implementing a given interface; or indeed any good way to traverse an interface's sub-interface tree at all, given that getSubclasses() does not work for interfaces either.
Am I missing something? I would have expected "get all transitive sub-nodes of the class tree" to be a standard feature, but I cannot find anything.
