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.
