- 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.
@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
runT run()Performs the computation. This method will be called by
AccessController.doPrivilegedafter enabling privileges.
- a class-dependent value that may represent the results of the
computation. Each class that implements
PrivilegedActionshould document what (if anything) this value represents.
