public class DataCache<V>
extends LazyValueCache<Ref,V>

cache for storing resource data. A data cache runs in two modes:

• memory resident mode: The data is always in the memory. no backing persistence is utilized.
• weak mode with persistence backing: the data is cached in the memory using weak or soft references. A backing persistent store provides the values if the cached data is garbage collected
