Class Overview
A convenience class for loading a system library as a privileged action.
An instance of this class can be used as the argument of
AccessController.doPrivileged
.
The following code attempts to load the system library named
"lib"
as a privileged action:
java.security.AccessController.doPrivileged(new LoadLibraryAction("lib"));

LoadLibraryAction
(String theLib)
