public class SpdStaticStreamGraph
extends ScheduledStaticStreamGraph

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 to at.dms.kjc.flatgraph.StaticStreamGraph is to allow layout and scheduling information to be associated with a StatisStreamGraph. It is a bit confusing casting something which already appears to be of type StaticStreamGraph to StaticStreamGraph, we should have had different names.
