pack-priv Class AccessibleMembersLookup

extends Object
Class Inheritance
Imports
java.lang.reflect.Method, .Modifier, java.util.Arrays, .Collection, .HashMap, .LinkedHashMap, .Map
Utility class for discovering accessible methods and inner classes. Normally, a public member declared on a class is accessible (that is, it can be invoked from anywhere). However, this is not the case if the class itself is not public, or belongs to a restricted-access package. In that case, it is required to lookup a member in a publicly accessible superclass or implemented interface of the class, and use it instead of the member discovered on the class.
