public interface Lifecycle

Lifecycle interface for kernel components. Init is called first, followed by start, and then any number of stop-start sequences, and finally stop and shutdown. As a stop-start cycle could be due to change of configuration, please perform anything that depends on config in start(). Implementations can throw any exception. Caller must handle this properly. The primary purpose of init in a component is to set up structure: instantiate dependent objects, register handlers/listeners, etc. Only in start should the component actually do anything with this structure. Stop reverses whatever was done in start, and shutdown finally clears any set-up structure, if necessary.
