Class GetBooleanAction

java.lang.Object
com.sun.jini.action.GetBooleanAction
All Implemented Interfaces:
PrivilegedAction
public class GetBooleanAction extends Object implements PrivilegedAction
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 or Security.doPrivileged.

The following code retrieves the boolean value of the system property named "prop" as a privileged action: 

boolean b = ((Boolean) Security.doPrivileged(
                new GetBooleanAction("prop"))).booleanValue();

If the protection domain of the immediate caller of doPrivileged or the protection domain of this class does not imply the permissions necessary for the operation, the behavior is as if the system property is not defined.
