Class GuardedObject
java.lang.Object
java.security.GuardedObject
- All Implemented Interfaces:
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 getObject
method, which invokes the
checkGuard
method on the Guard object that is
guarding access. If access is not allowed,
an exception is thrown.
