Package org.jivesoftware.util.cache

Interface Summary

Interface	Description
Cache<K extends Serializable,V extends Serializable>	General purpose cache.
Cacheable	Interface that defines the necessary behavior for objects added to a Cache.
CacheFactoryStrategy	Implementation of CacheFactory that relies on the specific clustering solution.
ClusterTask<V>	An interface to mix in Externalizable and Runnable, which are both required for sending invokable tasks across a cluster.
ExternalizableUtilStrategy	Interface that allows to provide different ways for implementing serialization of objects.

Class Summary

Class	Description
CacheFactory	Creates Cache objects.
CacheSizes	Utility class for determining the sizes in bytes of commonly used objects.
CacheUtil	Utility methods for working with caches.
CacheWrapper<K extends Serializable,V extends Serializable>	Acts as a proxy for a Cache implementation.
CaffeineCache<K extends Serializable,V extends Serializable>	Wraps an instance of Ben Manes' Caffeine cache in a class that inherits from Cache.
ComponentCacheWrapper<K extends Serializable,V extends Serializable>	This specialized wrapper is used for the Components cache, which should not be purged.
ConsistencyChecks	This class defines methods that verify that the state of a cache and its various supporting data structures (in which some data duplication is expected) is consistent.
ConsistencyMonitor	Caches, especially clustered caches, have various supporting data structures that allow them to work properly in certain conditions.
ConsistencyMonitor.Task
DefaultCache<K extends Serializable,V extends Serializable>	Default, non-distributed implementation of the Cache interface.
DefaultExternalizableUtil	Default serialization strategy.
DefaultLocalCacheStrategy	CacheFactoryStrategy for use in Openfire.
ExternalizableUtil	Utility methods to assist in working with the Externalizable interfaces.
ReverseLookupComputingCacheEntryListener<K,V>	Cache entry listener implementation that maintains a reverse lookup map for the cache that is being observed, which is used to identify what cluster nodes are the logical owner of a particular cache entry.
ReverseLookupUpdatingCacheEntryListener<K,V>	Cache entry listener implementation that maintains a reverse lookup map for the cache that is being observed, which is used to identify what cluster node is the logical owner of a particular cache entry.
SerializingCache<K extends Serializable,V extends Serializable>	A Cache implementation that stores data in serialized form.

Enum Summary

Enum	Description
Cache.CapacityUnit	Defines the unit used to calculate the capacity of the cache.

Exception Summary

Exception	Description
CannotCalculateSizeException	Flags an exception when we cannot determine size of the object to be cached.
