/**
 * Convenience subclass of Quartz' CronTrigger class that eases
 * bean-style usage.
 *
 * 

CronTrigger itself is already a JavaBean but lacks sensible * defaults. This class uses the Spring bean name as job name, the * Quartz default group ("DEFAULT") as job group, the current time * as start time, and the default timezone if not specified. * *

This class will also register the trigger with the job name * and group of a given JobDetail. This allows SchedulerFactoryBean * to automatically register a trigger for the respective JobDetail, * instead of registering the JobDetail separately. * * @author Juergen Hoeller * @since 18.02.2004 * @see #setName * @see #setGroup * @see #setStartTime * @see #setJobName * @see #setJobGroup * @see #setJobDetail * @see SchedulerFactoryBean#setTriggers * @see SchedulerFactoryBean#setJobDetails */ public class CronTriggerBean extends CronTrigger implements JobDetailAwareTrigger, BeanNameAware, InitializingBean { private static final Constants constants = new Constants(CronTrigger.class); private JobDetail jobDetail; private String beanName; /** * Set the misfire instruction via the name of the corresponding * constant in the SimpleTrigger class.
