Interface LifeCycleHook

public interface LifeCycleHook

Provides a method in which users can hook into the startup and shutdown lifecycle of Gremlin Server. Creating an instance of this interface in a Gremlin Server initialization script enables the ability to get a callback when the server starts and stops. The hook is guaranteed to execute once at in both cases.
