public class GuardedObject extends Object implements SerializableA 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 the
checkGuardmethod on the Guard object that is guarding access. If access is not allowed, an exception is thrown.
GuardedObjectConstructs 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.
