java.lang.Objectinfo.sswap.api.servlet.RRGCache
public class RRGCache
Manages cached RRGs and information about them (including information about RRGs that have not yet been computed, but they already have a token (identifier) so that the clients can query/poll for them). The underlying cache implementation is currently provided by EHCache
