public class TurbineNonPersistentSchedulerService
extends TurbineSchedulerService

Service for a cron like scheduler that uses the TurbineResources.properties file instead of the database. The methods that operate on jobs ( get,add,update,remove ) only operate on the queue in memory and changes are not reflected to the properties file which was used to initilize the jobs. An example is given below. The job names are the class names that extend ScheduledJob.

 services.SchedulerService.scheduler.job.scheduledJobName.ID=1
 services.SchedulerService.scheduler.job.scheduledJobName.SECOND=-1
 services.SchedulerService.scheduler.job.scheduledJobName.MINUTE=-1
 services.SchedulerService.scheduler.job.scheduledJobName.HOUR=7
 services.SchedulerService.scheduler.job.scheduledJobName.WEEKDAY=-1
