public class AccessControllerAdapter

extends Object

implements AccessController

This class provides a concrete implementation of an AccessController that provides access to all objects. No access control check is performed. It is assumed that no access control is needed, a sub-class will override one or more of the methods, or another process will be responsible for access control.
