class	PreAggrWindowWithNaturalMonthIterator
class	SingleTimeWindowIterator	Used for aggregation with only one time window.

Methods in org.apache.iotdb.db.mpp.aggregation.timerangeiterator that return ITimeRangeIterator

Modifier and Type	Method	Description
static ITimeRangeIterator	TimeRangeIteratorFactory.getTimeRangeIterator(long startTime, long endTime, long interval, long slidingStep, boolean isAscending, boolean isIntervalByMonth, boolean isSlidingStepByMonth, boolean leftCRightO, boolean outputPartialTimeWindow)	The method returns different implements of ITimeRangeIterator depending on the parameters.

Uses of ITimeRangeIterator in org.apache.iotdb.db.mpp.execution.operator

Methods in org.apache.iotdb.db.mpp.execution.operator that return ITimeRangeIterator

Modifier and Type	Method	Description
static ITimeRangeIterator	AggregationUtil.initTimeRangeIterator(GroupByTimeParameter groupByTimeParameter, boolean ascending, boolean outputPartialTimeWindow)	If groupByTimeParameter is null, which means it's an aggregation query without down sampling.
