Classes in com.espertech.esper.view.std that implement Viewable

Modifier and Type	Class and Description
class	AddPropertyValueOptionalView This view simply adds a property to the events posted to it.
class	FirstElementView View retaining the very first event.
class	FirstUniqueByPropertyView This view retains the first event for each multi-key of distinct property values.
class	GroupByViewImpl The group view splits the data in a stream to multiple subviews, based on a key index.
class	GroupByViewReclaimAged
class	LastElementView This view is a very simple view presenting the last event posted by the parent view to any subviews.
class	MergeView The merge view works together with a group view that splits the data in a stream to multiple subviews, based on a key index.
class	SizeView This view is a very simple view presenting the number of elements in a stream or view.
class	UniqueByPropertyView This view includes only the most recent among events having the same value for the specified field or fields.

Uses of Viewable in com.espertech.esper.view.window

Classes in com.espertech.esper.view.window that implement Viewable

Modifier and Type	Class and Description
class	ExpressionBatchView This view is a moving window extending the into the past until the expression passed to it returns false.
class	ExpressionViewBase This view is a moving window extending the into the past until the expression passed to it returns false.
class	ExpressionWindowView This view is a moving window extending the into the past until the expression passed to it returns false.
class	ExternallyTimedBatchView Batch window based on timestamp of arriving events.
class	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.
class	FirstLengthWindowView A length-first view takes the first N arriving events.
class	FirstTimeView
class	KeepAllView This view is a keep-all data window that simply keeps all events added.
class	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.
class	LengthBatchViewRStream Same as the LengthBatchView, this view also supports fast-remove from the batch for remove stream events.
class	LengthWindowView This view is a moving window extending the specified number of elements into the past.
class	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.
class	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.
class	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.
class	TimeBatchView A data view that aggregates events in a stream and releases them in one batch at every specified time interval.
class	TimeBatchViewRStream Same as the TimeBatchView, this view also supports fast-remove from the batch for remove stream events.
class	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.
class	TimeWindowView This view is a moving timeWindow extending the specified amount of milliseconds into the past.
