Interface HostingSupervisor

All Superinterfaces:
ManagedInvocation
All Known Implementing Classes:
ApplicationManagerHost
public interface HostingSupervisor extends ManagedInvocation
Physical hosting boundary. Implementations must inspect actual runtime state after uncertain completion; controller state alone never proves a replacement. ApplicationManagerHost is the built-in runtime implementation. Supervisors do not grant coordination authority themselves.
