Record Class CaffeineCacheMapper<K,R,V>

java.lang.Object
java.lang.Record
org.infinispan.container.impl.CaffeineCacheMapper<K,R,V>
Type Parameters:
K - The original cache key type
R - The mapped type
V - The value type of the Caffeine cache which is unchanged
Record Components:
delegate - The actual Caffeine cache to map the key to and from
keyMapper - the way to map the key to a different type
keyUnmapper - the way to unmap the different type to the cache key type
All Implemented Interfaces:
com.github.benmanes.caffeine.cache.Cache<R,V>
public record CaffeineCacheMapper<K,R,V>(com.github.benmanes.caffeine.cache.Cache<K,V> delegate, InjectiveFunction<? super K, ? extends R> keyMapper, InjectiveFunction<? super R, ? extends K> keyUnmapper) extends Record implements com.github.benmanes.caffeine.cache.Cache<R,V>
Mapper class that can be used with caffeine based caches to map a key to a different key as necessary. Note this class does not implement mapping for all optional classes provided from caffeine and is thus why it is in an impl package of core and not in the commons module like KeyMapperMap which does.
