Package com.google.common.cache

@CheckReturnValue @NullMarked package com.google.common.cache

Discouraged (in favor of Caffeine) caching utilities.

The core interface used to represent caches is Cache. In-memory caches can be configured and created using CacheBuilder, with cache entries being loaded by CacheLoader. Statistics about cache performance are exposed using CacheStats.

See the Guava User Guide article on caches.

This package is a part of the open-source Guava library.

Class	Description
AbstractCache<K,V>	This class provides a skeletal implementation of the Cache interface to minimize the effort required to implement this interface.
AbstractCache.SimpleStatsCounter	A thread-safe AbstractCache.StatsCounter implementation for use by Cache implementors.
AbstractCache.StatsCounter	Accumulates statistics during the operation of a Cache for presentation by Cache.stats().
AbstractLoadingCache<K,V>	This class provides a skeletal implementation of the Cache interface to minimize the effort required to implement this interface.
Cache<K,V>	A semi-persistent mapping from keys to values.
CacheBuilder<K,V>	A builder of LoadingCache and Cache instances.
CacheBuilderSpec	A specification of a CacheBuilder configuration.
CacheLoader<K,V>	Computes or retrieves values, based on a key, for use in populating a LoadingCache.
CacheLoader.InvalidCacheLoadException	Thrown to indicate that an invalid response was returned from a call to CacheLoader.
CacheLoader.UnsupportedLoadingOperationException	Exception thrown by loadAll() to indicate that it is not supported.
CacheStats	Statistics about the performance of a Cache.
ForwardingCache<K,V>	A cache which forwards all its method calls to another cache.
ForwardingCache.SimpleForwardingCache<K,V>	A simplified version of ForwardingCache where subclasses can pass in an already constructed Cache as the delegate.
ForwardingLoadingCache<K,V>	A cache which forwards all its method calls to another cache.
ForwardingLoadingCache.SimpleForwardingLoadingCache<K,V>	A simplified version of ForwardingLoadingCache where subclasses can pass in an already constructed LoadingCache as the delegate.
LoadingCache<K,V>	A semi-persistent mapping from keys to values.
RemovalCause	The reason why a cached entry was removed.
RemovalListener<K,V>	An object that can receive a notification when an entry is removed from a cache.
RemovalListeners	A collection of common removal listeners.
RemovalNotification<K,V>	A notification of the removal of a single entry.
Weigher<K,V>	Calculates the weights of cache entries.
