Examples of DaemonFactory

org.apache.derby.iapi.services.daemon.DaemonFactory
Daemon Factory can create new DaemonService, which runs on seperate background threads. One can use these DaemonService to handle background clean up task by implementing Serviceable and subscribing to a DaemonService. A DaemonService is a background worker thread which does asynchronous I/O and general clean up. It should not be used as a general worker thread for parallel execution. A DaemonService can be subscribe to by many Serviceable objects and a daemon will call that object's performWork from time to time. These performWork method should be well behaved - in other words, it should not take too long or hog too many resources or deadlock with anyone else. And it cannot (should not) error out. The best way to use a daemon is to have an existing DaemonService and subscribe to it. If you can't find an existing one, then make one thusly: DaemonService daemon = DaemonFactory.createNewDaemon(); After you have a daemon, you can subscribe to it by int myClientNumber = daemon.subscribe(serviceableObject); and ask it to run performWork for you ASAP by daemon.serviceNow(myClientNumber); Or, for one time service, you can enqueue a Serviceable Object by daemon.enqueue(serviceableObject, true); - urgent service daemon.enqueue(serviceableObject, false); - non-urgent service @see DaemonService @see Serviceable
