Interface | Description |
---|---|
AbstractCache.StatsCounter |
Accumulates statistics during the operation of a
Cache for presentation by Cache.stats() . |
Cache<K,V> |
A semi-persistent mapping from keys to values.
|
LoadingCache<K,V> |
A semi-persistent mapping from keys to values.
|
RemovalListener<K,V> |
An object that can receive a notification when an entry is removed from a cache.
|
Weigher<K,V> |
Calculates the weights of cache entries.
|
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. |
AbstractLoadingCache<K,V> |
This class provides a skeletal implementation of the
Cache interface to minimize the
effort required to implement this interface. |
CacheBuilder<K,V> |
A builder of
LoadingCache and Cache instances having any combination of the
following features:
automatic loading of entries into the cache
least-recently-used eviction when a maximum size is exceeded
time-based expiration of entries, measured since last access or last write
keys automatically wrapped in weak references
values automatically wrapped in weak or
soft references
notification of evicted (or otherwise removed) entries
accumulation of cache access statistics
|
CacheBuilderSpec |
A specification of a
CacheBuilder configuration. |
CacheLoader<K,V> |
Computes or retrieves values, based on a key, for use in populating a
LoadingCache . |
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. |
RemovalListeners |
A collection of common removal listeners.
|
RemovalNotification<K,V> |
A notification of the removal of a single entry.
|
Enum | Description |
---|---|
RemovalCause |
The reason why a cached entry was removed.
|
Exception | Description |
---|---|
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. |
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
.
