Guava: Google Core Libraries for Java 33.1.0-jre · 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.

Interface Summary

Modifier and Type	Interface and Description
public interface	Cache< the type of the cache's keys, which are not permitted to be null K, the type of the cache's values, which are not permitted to be null V> A semi-persistent mapping from keys to values.
public interface	LoadingCache< the type of the cache's keys, which are not permitted to be null K, the type of the cache's values, which are not permitted to be null V> A semi-persistent mapping from keys to values.
pack-priv interface	LongAddable Abstract interface for objects that can concurrently add longs.
pack-priv interface	ReferenceEntry<K, V> An entry in a reference map.
public interface	RemovalListener< the most general type of keys this listener can listen for; for example `Object` if any key is acceptable K, the most general type of values this listener can listen for; for example `Object` if any key is acceptable V> An object that can receive a notification when an entry is removed from a cache.
public interface	Weigher<K, V> Calculates the weights of cache entries.

Annotation Summary

Modifier and Type	Annotation and Description
pack-priv @interface	ElementTypesAreNonnullByDefault Marks all "top-level" types as non-null in a way that is recognized by Kotlin.
pack-priv @interface	ParametricNullness Annotates a "top-level" type-variable usage that takes its nullness from the type argument supplied by the user of the class.

Class Summary

Modifier and Type	Class and Description
public abstract class	AbstractCache<K, V> This class provides a skeletal implementation of the `Cache` interface to minimize the effort required to implement this interface.
public abstract class	AbstractLoadingCache<K, V> This class provides a skeletal implementation of the `Cache` interface to minimize the effort required to implement this interface.
public class	CacheBuilder< the most general key type this builder will be able to create caches for. This is normally `Object` unless it is constrained by using a method like `#removalListener`. Cache keys may not be null. K, the most general value type this builder will be able to create caches for. This is normally `Object` unless it is constrained by using a method like `#removalListener`. Cache values may not be null. V> A builder of `LoadingCache` and `Cache` instances.
public class	CacheBuilderSpec A specification of a `CacheBuilder` configuration.
public abstract class	CacheLoader<K, V> Computes or retrieves values, based on a key, for use in populating a `LoadingCache`.
public class	CacheStats Statistics about the performance of a `Cache`.
public abstract class	ForwardingCache<K, V> A cache which forwards all its method calls to another cache.
public abstract class	ForwardingLoadingCache<K, V> A cache which forwards all its method calls to another cache.
pack-priv class	LocalCache<K, V> The concurrent hash map implementation built by `CacheBuilder`.
pack-priv class	LongAddables Source of `LongAddable` objects that deals with GWT, Unsafe, and all that.
pack-priv class	LongAdder One or more variables that together maintain an initially zero `long` sum.
public class	RemovalListeners A collection of common removal listeners.
public class	RemovalNotification<K, V> A notification of the removal of a single entry.
pack-priv abstract class	Striped64 A package-local class holding common representation and mechanics for classes supporting dynamic striping on 64bit values.
