<R> StreamStage<WindowResult<R>> |
StageWithWindow.aggregate(AggregateOperation1<? super T,?,? extends R> aggrOp)
Attaches a stage that performs the given aggregate operation over all
the items that belong to a given window.
|
default <T1,R0,R1> StreamStage<WindowResult<Tuple2<R0,R1>>> |
StageWithWindow.aggregate2(AggregateOperation1<? super T,?,? extends R0> aggrOp0,
StreamStage<T1> stage1,
AggregateOperation1<? super T1,?,? extends R1> aggrOp1)
Attaches a stage that performs the given co-aggregate operations over
the items from this stage and
stage1 you supply. |
<T1,R> StreamStage<WindowResult<R>> |
StageWithWindow.aggregate2(StreamStage<T1> stage1,
AggregateOperation2<? super T,? super T1,?,? extends R> aggrOp)
Attaches a stage that performs the given aggregate operation over all
the items that belong to the same window.
|
default <T1,T2,R0,R1,R2> |
StageWithWindow.aggregate3(AggregateOperation1<? super T,?,? extends R0> aggrOp0,
StreamStage<T1> stage1,
AggregateOperation1<? super T1,?,? extends R1> aggrOp1,
StreamStage<T2> stage2,
AggregateOperation1<? super T2,?,? extends R2> aggrOp2)
Attaches a stage that performs the given aggregate operation over all
the items that belong to the same window.
|
<T1,T2,R> StreamStage<WindowResult<R>> |
StageWithWindow.aggregate3(StreamStage<T1> stage1,
StreamStage<T2> stage2,
AggregateOperation3<? super T,? super T1,? super T2,?,? extends R> aggrOp)
Attaches a stage that performs the given aggregate operation over the
items it receives from this stage as well as
stage1 and stage2 you supply. |
StreamStage<WindowResult<ItemsByTag>> |
WindowAggregateBuilder.build()
Creates and returns a pipeline stage that performs a windowed
co-aggregation of the stages registered with this builder object.
|
<A,R> StreamStage<WindowResult<R>> |
WindowAggregateBuilder1.build(AggregateOperation<A,R> aggrOp)
Creates and returns a pipeline stage that performs a windowed
co-aggregation of the pipeline stages registered with this builder
object.
|
default StreamStage<WindowResult<T>> |
StageWithWindow.distinct()
Attaches a stage that passes through just the items that are distinct
within their window (no two items emitted for a window are equal).
