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 CacheManagers.

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.

Since:

3.0

Method Detail

getCache

<K,V> ICache<K,V> getCache(String name)

Returns the cache instance with the specified, optionally prefixed, cache name:

      <prefixed_cache_name> = [<uri_prefix>/][<cl_prefix>/]<simple_cache_name>
 

where <simple_cache_name> is the cache name without any prefix.

It's possible to use the cache as a data source or sink in a Jet Pipeline, using Sources#cache(String) or Sinks#cache(String) and the change stream of the cache can be read using Sources#cacheJournal(String, JournalInitialPosition).

Parameters:

name - the prefixed name of the cache

Returns:

the cache instance with the specified prefixed name

Throws:

CacheNotExistsException - if there is no configured or created cache with the specified prefixed name

IllegalStateException - if a valid JCache library does not exist in the classpath (1.0.0-PFD or 0.x versions are not valid)
