package sun.security.action;

A convenience class for retrieving the boolean value of a system property
as a privileged action.
An instance of this class can be used as the argument of
AccessController.doPrivileged.
The following code retrieves the boolean value of the system
property named "prop" as a privileged action:
boolean b = java.security.AccessController.doPrivileged
             (new GetBooleanAction("prop")).booleanValue();
