All Implemented Interfaces:

Schedulable, com.ibm.itim.util.xml.objectstream.Importable, java.io.Serializable

public class RecurringTimeSchedule
extends java.lang.Object
implements Schedulable, com.ibm.itim.util.xml.objectstream.Importable

RecurringTimeSchedule is a class used to represent a recurring time that can be used for scheduling when implementing the Schedulable interface. This class has the flexibility to define the time based on hours, minutes, month, day of the week, day of the month, quarterly, and semi-annually. The following values are the example values for the different typs of schedules(all the remaining values of the schedule should be set to 0)

• Hourly : hour = -1.
• Daily at 6.30 AM : minute = 30, hour = 6, dayOfMonth = -1.
• Every Monday (Weekly) at 6.30 AM : minute = 30, hour = 6, dayOfWeek = 2.
• 10^th day of every month(Monthly) at 6.30 AM : minute = 30, hour = 6, month = -1, dayOfMonth = 10.
• Annually April 1 at 6.30 AM : minute = 30, hour = 6, month = 4, dayOfMonth = 1.
• Daily during March(specific month) at 6.30 AM : minute = 30, hour = 6, month = 3, dayOfWeek = -1.
• 10^th day of each quarter(Quarterly) at 6.30 AM : minute = 30, hour = 6, dayOfQuarter = 10.
• 10^th day of half year(Semi-Annually) at 6.30 AM : minute = 30, hour = 6, dayOfSemiAnnually = 10.

RecurringTimeSchedule

public RecurringTimeSchedule(int minute,
                             int hour,
                             int dayOfMonth,

Constructs the RecurringTimeSchedule with the given schedule parameters.

Parameters:

minute - minute of the schedule. Allowed values are 0-59.

hour - hour of the schedule. Allowed values are 0-23.

dayOfMonth - day of month of the schedule (-1 if every day). This attribute is exclusive with dayOfWeek.

Allowed values are 1-28, if the schedule is set to monthly otherwise the allowed value varies according to the month value.

month - month of the alarm (-1 if every month). Allowed values are 1-12 (1 = January, 2 = February, ...).

dayOfWeek - day of week of the alarm (-1 if every day). This attribute is exclusive with dayOfMonth. Allowed values are 1-7 (1 = Sunday, 2 = Monday, ...). java.util.Calendar constants can be used.

RecurringTimeSchedule

public RecurringTimeSchedule(int minute,
                             int hour,
                             int dayOfMonth,

                             int dayOfQuarter,
                             int dayOfSemiAnnual)

Constructs the RecurringTimeSchedule with the given schedule parameters. This also takes the parameter for day of quarter and day of semi-annual. If the dayOfSemiAnnual value is set to the schedule, then it ignores the dayOfQuarter value.

Parameters:

minute - minute of the schedule. Allowed values are 0-59.

hour - hour of the schedule. Allowed values are 0-23.

dayOfMonth - day of month of the schedule (-1 if every day). This attribute is exclusive with dayOfWeek.

dayOfQuarter - (0 for disabled by quarterly, otherwise 1-90) dayOfQuarter is exclusive with dayOfMonth, dayOfWeek and dayOfSemiAnnual, therefore value of dayOfMonth, dayOfWeek and dayOfSemiAnnual is set to ignore.

dayOfSemiAnnual - (0 for disabled by semi-annually, otherwise 1-180) dayOfSemiAnnual is exclusive with dayOfMonth, dayOfWeek and dayOfQuarter therefore value of dayOfMonth, dayOfWeek and dayOfQuarter is set to ignore.
