Interface PrivilegedAction<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 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:

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