Method Detail

getPrefix

public static String getPrefix(URI uri,
               ClassLoader classLoader)

Gets the prefix of cache name without Hazelcast's CacheManager specific prefix HazelcastCacheManager.CACHE_MANAGER_PREFIX.

Parameters:

uri - an implementation specific URI for the Hazelcast's CacheManager (null means use Hazelcast's CachingProvider.getDefaultURI())

classLoader - the ClassLoader to use for the Hazelcast's CacheManager (null means use Hazelcast's CachingProvider.getDefaultClassLoader())

Returns:

the prefix of cache name without Hazelcast's CacheManager specific prefix HazelcastCacheManager.CACHE_MANAGER_PREFIX

getPrefixedCacheName

public static String getPrefixedCacheName(String name,
                          URI uri,
                          ClassLoader classLoader)

Gets the cache name with prefix but without Hazelcast's CacheManager specific prefix HazelcastCacheManager.CACHE_MANAGER_PREFIX.

Parameters:

name - the simple name of the cache without any prefix

uri - an implementation specific URI for the Hazelcast's CacheManager (null means use Hazelcast's CachingProvider.getDefaultURI())

classLoader - the ClassLoader to use for the Hazelcast's CacheManager (null means use Hazelcast's CachingProvider.getDefaultClassLoader())

Returns:

the cache name with prefix but without Hazelcast's CacheManager specific prefix HazelcastCacheManager.CACHE_MANAGER_PREFIX.

getDistributedObjectName

public static String getDistributedObjectName(String cacheName)

Convenience method to obtain the name of Hazelcast distributed object corresponding to the cache identified by the given cacheName, assuming null URI and ClassLoader prefixes. This is equivalent to invoking getDistributedObjectName(String, URI, ClassLoader) with null passed as URI and ClassLoader arguments.

Parameters:

cacheName - the simple name of the cache without any prefix

Returns:

the name of the ICache distributed object corresponding to given cacheName, assuming null URI & class loader prefixes.

getDistributedObjectName(String, URI, ClassLoader)

getDistributedObjectName

public static String getDistributedObjectName(String cacheName,
                              URI uri,
                              ClassLoader classLoader)

Convenience method to obtain the name of Hazelcast distributed object corresponding to the cache identified by the given arguments. The distributed object name returned by this method can be used to obtain the cache as a Hazelcast ICache as shown in this example:

      HazelcastInstance hz = Hazelcast.newHazelcastInstance();

      // Obtain Cache via JSR-107 API
      CachingProvider hazelcastCachingProvider = Caching.getCachingProvider(
                  "com.hazelcast.cache.HazelcastCachingProvider",
                  HazelcastCachingProvider.class.getClassLoader());
      CacheManager cacheManager = hazelcastCachingProvider.getCacheManager();
      Cache testCache = cacheManager.createCache("test", new MutableConfiguration<String, String>());

      // URI and ClassLoader are null, since we created this cache with the default CacheManager,
      // otherwise we should pass the owning CacheManager's URI & ClassLoader as arguments.
      String distributedObjectName = CacheUtil.asDistributedObjectName("test", null, null);

      // Obtain a reference to the backing ICache via HazelcastInstance.getDistributedObject.
      // You may invoke this on any member of the cluster.
      ICache<String, String> distributedObjectCache = (ICache) hz.getDistributedObject(
                  ICacheService.SERVICE_NAME,
                  distributedObjectName);
 

Parameters:

cacheName - the simple name of the cache without any prefix

uri - an implementation specific URI for the Hazelcast's CacheManager (null means use Hazelcast's CachingProvider.getDefaultURI())

classLoader - the ClassLoader to use for the Hazelcast's CacheManager (null means use Hazelcast's CachingProvider.getDefaultClassLoader())

Returns:

the name of the ICache distributed object corresponding to given arguments.
