public abstract class AbstractCronJob
extends Object
implements CronJob

A straight-forward abstract implementation of CronJob. If you exend it, you only need to implement run(), and the 'cronEntry' protected member var is available.

Method Summary

CronEntry	getEntry()
protected void	init() You can init by overriding this (no need to call super.init) This is called by init(CronEntry)
void	init(CronEntry cronEntry) If the CronJobs needs some initializing before the first run, then that can be put in this.
abstract void	run() Implement this.
void	stop() Empty implementation (probably that's what you want)

Method Detail

init

public final void init(CronEntry cronEntry)

If the CronJobs needs some initializing before the first run, then that can be put in this. Stores the CronEntry in protected member cronEntry. So extensions should override init() instead (in which they can use the cronEntry member).

Specified by:

init in interface CronJob

init

protected void init()

You can init by overriding this (no need to call super.init) This is called by init(CronEntry)

stop

public void stop()

Empty implementation (probably that's what you want)

Specified by:

stop in interface CronJob

getEntry

public final CronEntry getEntry()

Specified by:

getEntry in interface CronJob

run

public abstract void run()

Implement this.
