- - ### Uses of SlidingWindowPolicy in com.hazelcast.jet.core

    Methods in com.hazelcast.jet.core that return SlidingWindowPolicy
    Modifier and Type | Method and Description
    --- | ---
    `static SlidingWindowPolicy` | SlidingWindowPolicy.`slidingWinPolicy(long windowSize, long slideBy)` Returns the definition of a sliding window of length `windowSize` that slides by `slideBy`.
    `SlidingWindowPolicy` | SlidingWindowPolicy.`toTumblingByFrame()` Converts this definition to one defining a tumbling window of the same length as this definition's frame.
    `static SlidingWindowPolicy` | SlidingWindowPolicy.`tumblingWinPolicy(long windowSize)` Returns the definition of a tumbling window of length `windowSize`.
    `SlidingWindowPolicy` | SlidingWindowPolicy.`withOffset(long offset)` Returns a new window definition where all the frames are shifted by the given offset.

  - ### Uses of SlidingWindowPolicy in com.hazelcast.jet.core.processor

    Methods in com.hazelcast.jet.core.processor with parameters of type SlidingWindowPolicy
    Modifier and Type | Method and Description
    --- | ---
    `static <K,A> SupplierEx<Processor>` | Processors.`accumulateByFrameP(List<FunctionEx<?,? extends K>> keyFns, List<ToLongFunctionEx<?>> timestampFns, TimestampKind timestampKind, SlidingWindowPolicy winPolicy, AggregateOperation<A,?> aggrOp)` Returns a supplier of processors for the first-stage vertex in a two-stage sliding window aggregation setup (see the `class Javadoc` for an explanation of aggregation stages).
    `static <K,A,R,OUT> SupplierEx<Processor>` | Processors.`aggregateToSlidingWindowP(List<FunctionEx<?,? extends K>> keyFns, List<ToLongFunctionEx<?>> timestampFns, TimestampKind timestampKind, SlidingWindowPolicy winPolicy, long earlyResultsPeriod, AggregateOperation<A,? extends R> aggrOp, KeyedWindowResultFunction<? super K,? super R,? extends OUT> mapToOutputFn)` Returns a supplier of processors for a vertex that aggregates events into a sliding window in a single stage (see the `class Javadoc` for an explanation of aggregation stages).
    `static <K,A,R,OUT> SupplierEx<Processor>` | Processors.`combineToSlidingWindowP(SlidingWindowPolicy winPolicy, AggregateOperation<A,? extends R> aggrOp, KeyedWindowResultFunction<? super K,? super R,? extends OUT> mapToOutputFn)` Returns a supplier of processors for the second-stage vertex in a two-stage sliding window aggregation setup (see the `class Javadoc` for an explanation of aggregation stages).
