Class PrivilegedActionException

java.lang.Object
 extended by java.lang.Throwable
 extended by java.lang.Exception
 extended by java.security.PrivilegedActionException

All Implemented Interfaces:: Serializable

public class PrivilegedActionException
extends Exception
extends Exception

This exception is thrown by doPrivileged(PrivilegedExceptionAction) and doPrivileged(PrivilegedExceptionAction, AccessControlContext context) to indicate that the action being performed threw a checked exception. The exception thrown by the action can be obtained by calling the getException method. In effect, an PrivilegedActionException is a "wrapper" for an exception thrown by a privileged action.

As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "exception thrown by the privileged computation" that is provided at construction time and accessed via the getException() method is now known as the cause, and may be accessed via the Throwable.getCause() method, as well as the aforementioned "legacy method."

Method Detail

public Exception getException()

Returns the exception thrown by the privileged computation that resulted in this PrivilegedActionException.

Returns:: the exception thrown by the privileged computation that resulted in this PrivilegedActionException.

getCause

public Throwable getCause()

Returns the the cause of this exception (the exception thrown by the privileged computation that resulted in this PrivilegedActionException).

Overrides:: getCause in class Throwable

Returns:: the cause of this exception.
Since:: 1.4

toString

public String toString()

Description copied from class: Throwable

Returns a short description of this throwable. If this Throwable object was created with a non-null detail message string, then the result is the concatenation of three strings:

The name of the actual class of this object
": " (a colon and a space)
The result of the Throwable.getMessage() method for this object

If this Throwable object was created with a null detail message string, then the name of the actual class of this object is returned.

Overrides:: toString in class Throwable

Returns:: a string representation of this throwable.
