Interface PrivilegedExceptionAction

public interface PrivilegedExceptionAction

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.

See Also:
AccessController, AccessController.doPrivileged(PrivilegedExceptionAction), AccessController.doPrivileged(PrivilegedExceptionAction, AccessControlContext), PrivilegedAction

Method Summary
 Object run()
          Performs the computation.
 

Method Detail

run

public Object run()
           throws Exception
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:
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(PrivilegedExceptionAction), AccessController.doPrivileged(PrivilegedExceptionAction,AccessControlContext)
