 public class GuardedObject extends Object implements Serializable A GuardedObject is an object that is used to protect access to another object.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 getObjectmethod, which invokes thecheckGuardmethod on the Guard object that is guarding access. If access is not allowed, an exception is thrown.- Since:
