- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface PrivilegedAction<T>
A computation to be performed with privileges enabled. The computation is
performed by invoking
AccessController.doPrivileged
on the
PrivilegedAction
object. This interface is used only for
computations that do not throw checked exceptions; computations that
throw checked exceptions must use PrivilegedExceptionAction
instead.- Since:

run
T 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
PrivilegedAction
should document what (if anything) this value represents. - See Also:
