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.
Constructs a GuardedObject using the specified object and guard. If the Guard object is null, then no restrictions will be placed on who can access the object.
object- the object to be guarded.
guard- the Guard object that guards access to the object.
