Interface PrivilegedExceptionAction<T>
- Type Parameters:
T
- the type of the result of running the computation
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
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.- Since:

Method Details
-
run
Performs the computation. This method will be called byAccessController.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 implementsPrivilegedExceptionAction
should document the exceptions that its run method can throw.- See Also:
