PrivilegedAction

public interface PrivilegedAction

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.
