TODO:

declare on the various "Manager" interfaces, all of which use these method signatures. Perhaps rename as "IShutdown".

Nested Class Summary

static interface

IServiceShutdown.Options Options for IServiceShutdown implementations.

Method Summary

boolean	isOpen() Return true iff the service is running.
void	shutdown() The service will no longer accept new requests, but existing requests will be processed (sychronous).
void	shutdownNow() The service will no longer accept new requests and will make a best effort attempt to terminate all existing requests and return ASAP.

Method Detail

isOpen

boolean isOpen()

Return true iff the service is running.

shutdown

void shutdown()

The service will no longer accept new requests, but existing requests will be processed (sychronous). This method should await the termination of pending requests, but no longer than the timeout specified by IServiceShutdown.Options.SHUTDOWN_TIMEOUT. Implementations SHOULD be synchronized. If the service is aleady shutdown, then this method should be a NOP.

shutdownNow

void shutdownNow()

The service will no longer accept new requests and will make a best effort attempt to terminate all existing requests and return ASAP. This method should terminate any asynchronous processing, release all resources and return immediately. Implementations SHOULD be synchronized. If the service is aleady shutdown, then this method should be a NOP.
