Description

Interface Summary

Cache<KeyType extends Serializable,ValueType extends Serializable>	The Cache interface represents a cache intended for application-level caching.
CachedObject.Computation<Key extends Serializable,Value extends Serializable>	Callback invoked to compute an object if it was not found in the cache.
ComputedValue.Computation<T>	Computation

Class Summary

CachedObject<KeyType extends Serializable,ValueType extends Serializable>	Represents a cached object identified by the key it has in a certain Cache.
ComputedValue<T>	Utility class to deal with recomputation of a certain value.
EhCache<KeyType extends Serializable,ValueType extends Serializable>	Cache implemented on top of EhCache.
ForeverCache<KeyType extends Serializable,ValueType extends Serializable>	A very simple cache based on a HashMap, It never expires any entries, and has no bounds on its size.
ZeroCache<KeyType extends Serializable,ValueType extends Serializable>	A cache that does not cache.

Package org.wamblee.cache Description

This package provides an interface for a cache together with several implementations. The main interfaces and classes are:

• Cache: An interface representing an application-level cache with objects in the cache identified by keys.
• CachedObject: An object representing an object in a cache identified through a key. Upon expiry the cached object invokes a callback to recompute (and cache) the object again.
• ComputedValue: An object caching a computed value with a computation interface determining whether the object is out of date and allowing recomputation of the value.
