Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description

- Method Detail
  - serverReady
```
void serverReady()
```
    Called after the server startup processing is done and all services are ready
  - startShutdown
```
void startShutdown()
```
    Called at the start of shutdown. Must not block. This method is called for all registered EventCallback objects before finalShutdown() is called. Implementations may initiate, but not wait for, shutdown of the services they manage.
  - finalShutdown
```
void finalShutdown()
```
    Called after all startShutdown() calls have been processed. Implementations should terminate internal services immediately at this point. Waiting for termination should be kept to a minimum, unless critical for stability.
