net.esper.view.window.TimeAccumViewRStream
public final 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. See TimeAccumView
for the same behavior without
remove stream handling.
