Method Details

canAddClassInPackageOf

public static boolean canAddClassInPackageOf(Class<?> cls)

Helper method called to check whether it is acceptable to create a new class in package that given class is part of. This is used to prevent certain class of failures, related to access limitations: for example, we can not add classes in sealed packages, or core Java packages (java.*).
