Calendar (Quartz Enterprise Job Scheduler 2.5.1 API)

All Superinterfaces:

java.lang.Cloneable, java.io.Serializable

All Known Implementing Classes:

AnnualCalendar, BaseCalendar, CronCalendar, DailyCalendar, HolidayCalendar, MonthlyCalendar, WeeklyCalendar
```
public interface Calendar
extends java.io.Serializable, java.lang.Cloneable
```
An interface to be implemented by objects that define spaces of time during which an associated Trigger may (not) fire. Calendars do not define actual fire times, but rather are used to limit a Trigger from firing on its normal schedule if necessary. Most Calendars include all times by default and allow the user to specify times to exclude.
As such, it is often useful to think of Calendars as being used to exclude a block of time - as opposed to include a block of time. (i.e. the schedule "fire every five minutes except on Sundays" could be implemented with a SimpleTrigger and a WeeklyCalendar which excludes Sundays)

Implementations MUST take care of being properly Cloneable and Serializable.

Modifier and Type	Method	Description
`java.lang.Object`	`clone()`
`Calendar`	`getBaseCalendar()`	Get the base calendar.
`java.lang.String`	`getDescription()`	Return the description given to the `Calendar` instance by its creator (if any).
`long`	`getNextIncludedTime(long timeStamp)`	Determine the next time (in milliseconds) that is 'included' by the Calendar after the given time.
`boolean`	`isTimeIncluded(long timeStamp)`	Determine whether the given time (in milliseconds) is 'included' by the Calendar.
`void`	`setBaseCalendar(Calendar baseCalendar)`	Set a new base calendar or remove the existing one.
`void`	`setDescription(java.lang.String description)`	Set a description for the `Calendar` instance - may be useful for remembering/displaying the purpose of the calendar, though the description has no meaning to Quartz.
