Interface Summary

Interface	Description

ConfigurableCacheMap	An extension to the CacheMap interface that supports runtime configuration and monitoring of various caching properties.
ConfigurableCacheMap.Entry	A cache Entry carries information additional to the base Map Entry in order to support eviction and expiry.
ConfigurableCacheMap.EvictionApprover	EvictionApprover is used to approve the eviction of an entry from the underlying ConfigurableCacheMap.

BackingMapBinaryEntry	An implementation of the BinaryEntry interface that is based on specified binary key, binary value and BackingMapManagerContext.

BinaryStoreCacheStore<K,V>	A CacheStore that sits directly on top of a BinaryStore.
BlindCompactSerializationCache	BlindCompactSerializationCache is a CompactSerializationCache extension enforcing CompactSerializationCache to operate under a blind mode.
BundlingNamedCache	Bundling NamedCache implementation.
CacheEvent<K,V>	An extension of the MapEvent which allows to differentiate between client driven (natural) events and cache internal (synthetic) events.
CacheLoaderCacheStore<K,V>	A read-only CacheStore that wraps a CacheLoader.
CacheLoaderCacheStore.Iterable<K,V>	An extension to the CacheLoaderCacheStore that implements the IterableCacheLoader interface.
CacheStoreMap	A backing Map implementation that delegates all operations to a CacheStore.
CacheStoreMap.ReadWriteMap	A Map implementation that delegates straight through to a CacheStore.
CachingMap<K,V>	Map implementation that wraps two maps - a front map (assumed to be "inexpensive" and probably "incomplete") and a back map (assumed to be "complete" and "correct", but more "expensive") - using a read-through/write-through approach.
CompactSerializationCache	CompactSerializationCache is an implementation of ConfigurableCacheMap which is optimized for compact on-heap footprint.
CompactSerializationCache.TouchCountVisitor	TouchCountVisitor is applied to the touch-count map by EvictionPolicy implementations that rely on the touch-count to retrieve and adjust the touch-count.
ContinuousQueryCache<K,V_BACK,V_FRONT>	Create a materialized view of a NamedCache using the Coherence Continuous Query capability.
LocalCache	A LocalCache implementation that supports the JCache API, CacheLoader and CacheStore objects.
MapCacheStore<K,V>	A CacheStore that sits directly on top of a Map.
NearCache<K,V>	A "near cache" is a CachingMap whose front map is a size-limited and/or auto-expiring local cache, and whose back map is a distributed cache.

OldCache.InternalEvictionPolicy	The InternalEvictionPolicy represents a pluggable eviction policy for the non-pluggable built-in (internal) eviction policies supported by this cache implementation.
OldCache.InternalUnitCalculator	The InternalUnitCalculator represents a pluggable UnitCalculator for the non-pluggable built-in (internal) UnitCalculator implementation provided by this cache implementation.
OverflowMap	An Observable Map implementation that wraps two maps - a front map (assumed to be fast but limited in its maximum size) and a back map (assumed to be slower but much less limited in its maximum size).
OverflowMap.ExpirableStatus	The ExpirableStatus adds expiry to the base Status object.
OverflowMap.HistoricCacheEvent	A CacheEvent that carries a recent value (to avoid it being lost during eviction).
OverflowMap.Status	The Status object is used to manage concurrency at the key level for the key-level operations against the Map, to track all the items in the front Map, to manage the state transition for operations occurring against the Map, and to coordinate events across multiple threads.
ReadonlyNamedCache<K,V>	A simple extension of the WrapperNamedCache implementation that shields all content mutating operations such as put(), remove(), lock() etc.
ReadWriteBackingMap	Backing Map implementation that provides a size-limited cache of a persistent store and supports configurable write-behind and refresh- ahead caching.

ReadWriteBackingMap.EvictingBackupMap	A Map implementation used for a backup map that evicts all data that has been successfully written.
ReadWriteBackingMap.ReadLatch	A synchronization construct used to coordinate asynchronous loads by the refresh-ahead thread with cache accesses by other threads.

SimpleOverflowMap.FrontFilterConverter	A combination Filter and Converter used to iterate through the status map in order to iterate through the front keys.
SimpleOverflowMap.HashcodeComparator	A stateless Comparator that compares Object.hashCode() values.
SimpleOverflowMap.Status	The Status object is used to manage concurrency at the key level for the key-level operations against the Map, to track all the items in the front Map, to manage the state transition for operations occurring against the Map, and to coordinate events across multiple threads.
