public class ScheduledStaticStreamGraph
extends StaticStreamGraph

A StaticStreamGraph represents a subgraph of the application's StreamGraph where communication within the SSG is over static rate channels. The input/output (if either exists) of an SSG is dynamic, but the sources and sinks have their input/output rates zeroed, repectively. This extension allows scheduling of a StaticStreamGraph
