Class CronExpression

    • Constructor Detail

      • CronExpression

        public CronExpression​(String cronExpression)
        Constructs a new CronExpression based on the specified parameter.
        Parameters:
        cronExpression - String representation of the cron expression the new object should represent

      • CronExpression

        public CronExpression​(CronExpression expression)
        Constructs a new CronExpression as a copy of an existing instance.
        Parameters:
        expression - The existing cron expression to be copied

    • Method Detail

      • isSatisfiedBy

        public boolean isSatisfiedBy​(Date 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 Date getNextValidTimeAfter​(Date 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 Date getNextInvalidTimeAfter​(Date 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 TimeZone getTimeZone()
        Returns the time zone for which this CronExpression will be resolved.
        Returns:
        time zone

      • setTimeZone

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

      • toString

        public String toString()
        Returns the string representation of the CronExpression
        Overrides:
        toString in class Object
        Returns:
        a string representation of the CronExpression

      • isValidExpression

        public static boolean isValidExpression​(String cronExpression)
        Indicates whether the specified cron expression can be parsed into a valid cron expression
        Parameters:
        cronExpression - the expression to evaluate
        Returns:
        a boolean indicating whether the given expression is a valid cron expression
