 * <B>Assertion Description: </B> Most JDO implementations allow instances to be cached in a
 * second-level cache, and allow direct management of the cache by knowledgeable applications. The
 * second-level cache is typically a single VM cache and is used for persistent instances associated
 * with a single PersistenceManagerFactory. For the purpose of standardizing this behavior, the
 * DataStoreCache interface is used.
