Interface ShutdownController

All Known Implementing Classes:

ExecutorShutdownController, ShutdownController.Wrapper

public interface ShutdownController

The shutdown controller allows registering hooks run on the three shutdown phases:

• prepare: stop accepting new work (e.g. stop accepting HTTP requests).
• perform: shut things down, save state if applicable etc.
• finalize: shutdown the core components like the work thread pool or a database connections.

The shutdown controller also supports running shutdown-preventing actions. Any shutdown request will have to wait until all shutdown preventing actions are done. As soon as a shutdown is on the horizon (initiated or announced), no more shutdown preventing actions will be possible.
