Package com.hazelcast.jet
Interface JetCacheManager
public interface JetCacheManager
JetCacheManager
is the entry point to access JSR-107 (JCache) caches
via JetInstance
interface. Hazelcast Jet's JetCacheManager
provides access to JCache caches configured cluster-wide,
even when created by different JCache CacheManager
s.
Note that this interface is not related to JCache CacheManager
.
Its purpose is to host ICacheJet
related methods, separately from
JetInstance
, in order to allow frameworks that make
use of reflection and/or dynamic proxies (e.g. Mockito, Spring etc)
to operate on JetInstance
when JCache is not on the classpath.
