Interface Summary

Interface	Description
Cache<K,V>	A cache interface.
Cache.Loader<KK,VV>	Loader to get the value for the key into the cache.
Cache.RemovalListener<KK,VV>	Listener for removals from the cache.
Cache.Statistics	Interface for providing cache statistics, if enabled.
Cache.Weigher<KK,VV>	Weigher for determining the weight of an entry.
CacheBuilder<K,V,B extends CacheBuilder<K,V,B>>	A builder for a Cache
CacheBuilderWithWeight<K,V,B extends CacheBuilderWithWeight<K,V,B>>	A builder for a Cache
CachingObjectStorage	A wrapper around ObjectStorage that caches the contents returned by ObjectStorage.getObject(GetObjectRequest) on disk.
CachingObjectStorage.RowLockProvider
CachingObjectStorage.UncacheablePredicate	Interface for deciding if a request cannot be cached.
ConsistencyPolicy	This interface controls how conflicting items are evicted.

Class Summary

Class	Description
Cache.RemovalNotification<KK,VV>	Notification of a removal from the cache.
CachingObjectStorage.CachedInputStream	Input stream using a cached file.
CachingObjectStorage.Configuration	Configuration.
CachingObjectStorage.Configuration.ConfigurationBuilder	Builder for a caching configuration.
CachingObjectStorage.DefaultRowLockProvider
CachingObjectStorage.DefaultUncacheablePredicate	By default, this implementation does not cache requests with if-none-match set.
CachingObjectStorage.DeletionRunnable
CachingObjectStorage.GetObjectRequestCacheKey	We unfortunately need a wrapper around GetObjectRequest, because we don't want everything to be considered for equals and hashCode.
CachingObjectStorage.GetObjectResponseCacheValue
CachingObjectStorage.Handler	Implemented as proxy/invocation handler, so we don't have to add more and more methods that just client to the inner ObjectStorage instance.
CachingObjectStorage.PathHolder	It seems like the JDK is doing some kind of caching or re-use of Path instances, preventing PhantomReferences from working properly.
CachingObjectStorage.PathPhantomReference	This phantom reference is used to delete evicted cached files once they are not accessible anymore by the Java application (because there are no more references held to it).
CachingObjectStorage.RemovalListener
CachingObjectStorage.RowLock
NoOpConsistencyPolicy	This consistency policy does not do any evictions.
StrongConsistencyPolicy	This consistency policy evicts cache entries that have an etag that differs from the current etag.

Exception Summary

Exception	Description
Cache.UncheckedExecutionException	Exception was thrown while getting the cache value.
