Interface Summary

Interface	Description
IStreamRelativeAccess.IStreamRelativeAccessUpdateObserver	For indicating that the collection has been updated.
RandomAccessByIndex	Random access interface to insert stream and remove stream data based on an index.
RandomAccessByIndexObserver	For indicating that the collection has been updated.
RelativeAccessByEventNIndex	Provides access to prior events given an event from which to count back, and an index to look at.
RelativeAccessByEventNIndexGetter	Provides random-access into window contents by event and index as a combination.

Class Summary

Class	Description
ExpressionBatchView	This view is a moving window extending the into the past until the expression passed to it returns false.
ExpressionBatchViewFactory	Factory for ExpressionBatchView.
ExpressionViewBase	This view is a moving window extending the into the past until the expression passed to it returns false.
ExpressionViewFactoryBase	Base factory for expression-based window and batch view.
ExpressionWindowTimestampEventPair
ExpressionWindowTimestampEventPairIterator
ExpressionWindowView	This view is a moving window extending the into the past until the expression passed to it returns false.
ExpressionWindowViewFactory	Factory for ExpressionWindowView.
ExternallyTimedBatchView	Batch window based on timestamp of arriving events.
ExternallyTimedBatchViewFactory	Factory for ExternallyTimedBatchView.
ExternallyTimedWindowView	View for a moving window extending the specified amount of time into the past, driven entirely by external timing supplied within long-type timestamp values in a field of the event beans that the view receives.
ExternallyTimedWindowViewFactory	Factory for ExternallyTimedWindowView.
FirstLengthWindowView	A length-first view takes the first N arriving events.
FirstLengthWindowViewFactory	Factory for FirstLengthWindowView.
FirstTimeView
FirstTimeViewFactory	Factory for FirstTimeView.
IStreamRandomAccess	For use with length and time window views that must provide random access into data window contents provided for the "previous" expression if used.
IStreamRelativeAccess	Provides relative access to insert stream events for certain window.
KeepAllView	This view is a keep-all data window that simply keeps all events added.
KeepAllViewFactory	Factory for KeepAllView.
LengthBatchView	A data view that aggregates events in a stream and releases them in one batch when a maximum number of events has been collected.
LengthBatchViewFactory	Factory for TimeBatchView.
LengthBatchViewRStream	Same as the LengthBatchView, this view also supports fast-remove from the batch for remove stream events.
LengthWindowView	This view is a moving window extending the specified number of elements into the past.
LengthWindowViewFactory	Factory for LengthWindowView.
LengthWindowViewRStream	This view is a moving window extending the specified number of elements into the past, allowing in addition to remove events efficiently for remove-stream events received by the view.
RandomAccessByIndexGetter	Getter that provides an index at runtime.
RelativeAccessByEventNIndexGetterImpl	Provides random-access into window contents by event and index as a combination.
TimeAccumView	A data window view that holds events in a stream and only removes events from a stream (rstream) if no more events arrive for a given time interval.
TimeAccumViewFactory	Factory for TimeAccumView.
TimeAccumViewRStream	A data window view that holds events in a stream and only removes events from a stream (rstream) if no more events arrive for a given time interval, also handling the remove stream by keeping set-like semantics.
TimeBatchView	A data view that aggregates events in a stream and releases them in one batch at every specified time interval.
TimeBatchViewFactory	Factory for TimeBatchView.
TimeBatchViewFactoryParams	Parameters for batch views that provides common data flow parameter parsing.
TimeBatchViewRStream	Same as the TimeBatchView, this view also supports fast-remove from the batch for remove stream events.
TimeLengthBatchView	A data view that aggregates events in a stream and releases them in one batch if either one of these conditions is reached, whichever comes first: One, a time interval passes.
TimeLengthBatchViewFactory	Factory for TimeLengthBatchView.
TimeWindowView	This view is a moving timeWindow extending the specified amount of milliseconds into the past.
TimeWindowViewFactory	Factory for TimeWindowView.
