public class GuardedObject extends Object implements Serializable
A GuardedObject encapsulates a target object and a Guard object,
such that access to the target object is possible
only if the Guard object allows it.
Once an object is encapsulated by a GuardedObject,
access to that object is controlled by the
method, which invokes the
checkGuard method on the Guard object that is
guarding access. If access is not allowed,
an exception is thrown.
