      • CronExpression

        public CronExpression​( cronExpression)
        Constructs a new CronExpression based on the specified parameter.

      • CronExpression

        public CronExpression​(CronExpression expression)
        Constructs a new CronExpression as a copy of an existing instance.
        Parameters:

    • Method Detail

      • isSatisfiedBy

        public boolean isSatisfiedBy​( date)
        Indicates whether the given date satisfies the cron expression. Note that milliseconds are ignored, so two Dates falling on different milliseconds of the same second will always have the same result here.
        Parameters:
        date - the date to evaluate
        Returns:
        a boolean indicating whether the given date satisfies the cron expression

      • getNextValidTimeAfter

        public  getNextValidTimeAfter​( date)
        Returns the next date/time after the given date/time which satisfies the cron expression.
        Parameters:
        date - the date/time at which to begin the search for the next valid date/time
        Returns:
        the next valid date/time

      • getNextInvalidTimeAfter

        public  getNextInvalidTimeAfter​( date)
        Returns the next date/time after the given date/time which does not satisfy the expression
        Parameters:
        date - the date/time at which to begin the search for the next invalid date/time
        Returns:
        the next valid date/time

      • getTimeZone

        public  getTimeZone()
        Returns the time zone for which this CronExpression will be resolved.
        Returns:
        time zone

      • setTimeZone

        public void setTimeZone​( timeZone)
        Sets the time zone for which this CronExpression will be resolved.
        Parameters:
