Interface PrivilegedAction<T>
public interface PrivilegedAction<T>
A computation to be performed with privileges enabled. The computation is
performed by invoking AccessController.doPrivileged on the
PrivilegedAction object. This interface is used only for
computations that do not throw checked exceptions; computations that
throw checked exceptions must use PrivilegedExceptionAction
instead.
