Interface User

All Superinterfaces:
Principal
public interface User extends Principal
Represents an authenticated or system-level user identity within the Fluxzero Runtime.

A User provides role-based access information. User instances are propagated through message metadata and can be made available to business logic via getCurrent() or injection into handler methods.

To execute logic with a specific user bound to the current thread context, use apply(Callable) or run(ThrowingRunnable).
