cronAction

public abstract void cronAction()

This is the CORE METHOD of this class. You should invoke whatever logic you want your CronTask to perform from this method. This method should

1. check the shutdown variable before invoking any processing logic.
2. call resetErrorCount() if processing proceeds w/out error.
3. call incErrorCount() if a serious error occurs during the processing logic.

Getter for the shutdown variable.

Specified by:

isShutdown in interface CronTask

getName

public java.lang.String getName()

Should return the name of this CronTask. Note: you should limit yourself to returning "file name friendly" characters, e.g. no '!', '.' or spaces, etc. because the sring returned is used to create a file name by the store() method.

setCronTaskHistoryMsg
