Modifier and Type	Method and Description
Stream	Stream.aggregate(Aggregator agg, Fields functionFields)
Stream	Stream.aggregate(Fields inputFields, Aggregator agg, Fields functionFields)
Stream	Stream.partitionAggregate(Aggregator agg, Fields functionFields)
Stream	Stream.partitionAggregate(Fields inputFields, Aggregator agg, Fields functionFields)
Stream	Stream.slidingWindow(BaseWindowedBolt.Duration windowDuration, BaseWindowedBolt.Duration slidingInterval, WindowsStoreFactory windowStoreFactory, Fields inputFields, Aggregator aggregator, Fields functionFields) Returns a stream of tuples which are aggregated results of a window which slides at duration of slidingInterval and completes a window at windowDuration
Stream	Stream.slidingWindow(int windowCount, int slideCount, WindowsStoreFactory windowStoreFactory, Fields inputFields, Aggregator aggregator, Fields functionFields) Returns a stream of tuples which are aggregated results of a sliding window with every windowCount of tuples and slides the window after slideCount.
Stream	Stream.tumblingWindow(BaseWindowedBolt.Duration windowDuration, WindowsStoreFactory windowStoreFactory, Fields inputFields, Aggregator aggregator, Fields functionFields) Returns a stream of tuples which are aggregated results of a window that tumbles at duration of windowDuration
Stream	Stream.tumblingWindow(int windowCount, WindowsStoreFactory windowStoreFactory, Fields inputFields, Aggregator aggregator, Fields functionFields) Returns a stream of tuples which are aggregated results of a tumbling window with every windowCount of tuples.
Stream	Stream.window(WindowConfig windowConfig, Fields inputFields, Aggregator aggregator, Fields functionFields) Returns a stream of aggregated results based on the given window configuration which uses inmemory windowing tuple store.
Stream	Stream.window(WindowConfig windowConfig, WindowsStoreFactory windowStoreFactory, Fields inputFields, Aggregator aggregator, Fields functionFields) Returns stream of aggregated results based on the given window configuration.
