package java.security;


 A computation to be performed with privileges enabled, that throws one or
 more checked exceptions.  The computation is performed by invoking
 AccessController.doPrivileged on the
 PrivilegedExceptionAction object.  This interface is
 used only for computations that throw checked exceptions;
 computations that do not throw
 checked exceptions should use PrivilegedAction instead.

public interface PrivilegedExceptionAction<T> {
    
 Performs the computation.  This method will be called by
 AccessController.doPrivileged after enabling privileges.

 
 Returns:a class-dependent value that may represent the results of the
         computation.  Each class that implements
         PrivilegedExceptionAction should document what
         (if anything) this value represents. Throws:java.lang.Exception an exceptional condition has occurred.  Each class
         that implements PrivilegedExceptionAction should
         document the exceptions that its run method can throw. See also:AccessController.doPrivileged(java.security.PrivilegedExceptionAction)AccessController.doPrivileged(java.security.PrivilegedExceptionAction,java.security.AccessControlContext)
