public CronTrigger(java.lang.String expression)
CronTrigger from the pattern provided in the default time zone.expression - a space-separated list of time fields, following cron
expression conventionspublic CronTrigger(java.lang.String expression,
java.util.TimeZone timeZone)
CronTrigger from the pattern provided in the given time zone.expression - a space-separated list of time fields, following cron
expression conventionstimeZone - a time zone in which the trigger times will be generatedpublic java.lang.String getExpression()
public java.util.Date nextExecutionTime(TriggerContext triggerContext)
Next execution times are calculated based on the completion time of the previous execution; therefore, overlapping executions won't occur.
nextExecutionTime in interface TriggertriggerContext - context object encapsulating last execution times
and last completion timenull if the trigger won't fire anymorepublic boolean equals(java.lang.Object other)
