Interface	osid.calendaring.DateTimeIntervalList
Implements	`osid.OsidList`
Used By	`osid.calendaring.RecurringEvent`
	`osid.course.Activity`
	`osid.repository.AssetTemporalSession`
Description	Like all `OsidLists`, `DateTimeIntervalList` provides a means for accessing `DateTimeInterval` elements sequentially either one at a time or many at a time. Examples: while (dtil.hasNext()) { DateTimeInterval interval = dtil.getNextDateTimeInterval(); } or while (dtil.hasNext()) { DateTimeInterval[] intervals = dtil.getNextDateTimeIntervals(dtil.available()); }
Method	getNextDateTimeInterval
Description	Gets the next `DateTimeInterval` in this list.
Return	`osid.calendaring.DateTimeInterval`		the next `DateTimeInterval` in this list. The `hasNext()` method should be used to test that a next `DateTimeInterval` is available before calling this method.
Errors	ILLEGAL_STATE		no more elements available in this list
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getNextDateTimeIntervals
Description	Gets the next set of `DateTimeInterval` elements in this list which must be less than or equal to the number returned from `available()`.
Parameters	`cardinal`	`n`	the number of `DateTimeInterval` elements requested which should be less than or equal to `available()`
Return	`osid.calendaring.DateTimeInterval[]`		an array of `DateimeInterval` elements. The length of the array is less than or equal to the number specified.
Errors	ILLEGAL_STATE		no more elements available in this list
Errors	OPERATION_FAILED		unable to complete request
