- the type of key.V
- the type of value.public class CacheProxy<K,V> extends AbstractDistributedObject<ICacheService> implements EventJournalReader<EventJournalCacheEvent<K,V>>
This proxy is the implementation of ICache and javax.cache.Cache which is returned by HazelcastServerCacheManager. It represents a cache for server or embedded mode.
Each cache method actually is an operation which is sent to related partition(s) or node(s). Operations are executed on partition's or node's executor pools and the results are delivered to the user.
In order to access a CacheProxy by name, a cacheManager should be used. It's advised to use
ICache
instead.

This is equivalent to:

If the cache is configured for write-through operation mode, the underlying
configured CacheWriter
might be called to store
the value of the key to any kind of external resource.
