com.espertech.esper.view.internal.BufferView
A view that acts as an adapter between views and update listeners. The view can be added to a parent view. When the parent view publishes data, the view will forward the data to the UpdateListener implementation that has been supplied. If no UpdateListener has been supplied, then the view will cache the last data published by the parent view.
