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.
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.
