ptolemy.domains.sdf.kernel.CachedSDFScheduler

The CachedSDFScheduler extends the SDFScheduler by caching schedules. The cached schedules are labeled by their corresponding rate signatures, with the most recently used at the beginning of the cache queue. If the rate signatures are contained in the cache keys, then the corresponding schedule in the cache is used. Therefore, we do not need to recompute the schedule again.

The size of the cache in the CachedSDFScheduler is usually set by its containing director when constructing this scheduler. If the cache is full, the least recently used schedule (at the end of the cache) is discarded. @see SDFScheduler @author Ye Zhou. Contributor: Brian K.
