17 * This package provides an interface for a cache together with several implementations.
18 * The main interfaces and classes are:
20 * <li> {@link Cache}: An interface representing an application-level cache with objects in the
21 * cache identified by keys.
23 * <li> {@link CachedObject}: An object representing an object in a cache identified through a
24 * key. Upon expiry the cached object invokes a callback to recompute (and cache) the object
27 * <li> {@link ComputedValue}: An object caching a computed value with a computation interface
28 * determining whether the object is out of date and allowing recomputation of the value.
