public class TimeAccumView extends ViewSupport implements CloneableView, DataWindowView, StoppableView, StopCallback
No batch version of the view exists as the batch version is simply the remove stream of this view, which removes in batches.
The view is continuous, the insert stream consists of arriving events. The remove stream only posts current window contents when no more events arrive for a given timer interval.
