Class Summary

BufferView	A view that acts as an adapter between views and update listeners.
IntersectAsymetricView	A view that represents an intersection of multiple data windows.
IntersectBatchView	A view that represents an intersection of multiple data windows.
IntersectView	A view that represents an intersection of multiple data windows.
IntersectViewFactory	Factory for union-views.
LastPostObserverView	A view that retains the last update.
PatternRemoveDispatchView	View to handle pattern discarding for a single stream (no join).
PriorEventBufferMulti	Buffers view-posted insert stream (new data) and remove stream (old data) events for use with determining prior results in these streams, for multiple different prior events.
PriorEventBufferSingle	Buffers view-posted insert stream (new data) and remove stream (old data) events for use with serving prior results in these streams, for a single prior event.
PriorEventBufferUnbound	Buffer class for insert stream events only for use with unbound streams that inserts data only, to serve up one or more prior events in the insert stream based on an index.
PriorEventView	View that provides access to prior events posted by the parent view for use by 'prior' expression nodes.
PriorEventViewFactory	Factory for making PriorEventView instances.
PriorEventViewRelAccess
RouteResultView	View for processing split-stream syntax.
RouteResultViewHandlerAll	Handler for split-stream evaluating the all where-clauses and their matching select-clauses.
RouteResultViewHandlerFirst	Handler for split-stream evaluating the first where-clause matching select-clause.
SingleStreamDispatchView	View to dispatch for a single stream (no join).
UnionAsymetricView	A view that represents a union of multiple data windows wherein at least one is asymetric: it does not present a insert stream for each insert stream event received.
UnionView	A view that represents a union of multiple data windows.
UnionViewFactory	Factory for union-views.
