Class MultiplexingCacheInstanceManager

java.lang.Object
  org.hibernate.cache.jbc2.builder.MultiplexingCacheInstanceManager

All Implemented Interfaces:

CacheInstanceManager

Direct Known Subclasses:

JndiMultiplexingCacheInstanceManager

public class MultiplexingCacheInstanceManager
extends Object
implements CacheInstanceManager

Allows building separate Cache instances for each type of region, with the expectation that a single multiplexed JGroups resource (i.e. a multiplexed channel or a shared transport channel) will be shared between the caches.

Constructor Detail

MultiplexingCacheInstanceManager

public MultiplexingCacheInstanceManager()

Create a new MultiplexingCacheInstanceManager.

MultiplexingCacheInstanceManager

public MultiplexingCacheInstanceManager(org.jboss.cache.Cache jbcEntityCache,
                                        org.jboss.cache.Cache jbcCollectionCache,
                                        org.jboss.cache.Cache jbcTsCache,
                                        org.jboss.cache.Cache jbcQueryCache)

Create a new MultiplexingCacheInstanceManager using the provided Caches.

If this constructor is used, the start(Settings, Properties) method will make no attempt to create a cache factory or obtain caches from it. Only the Caches passed as arguments to this constructor will be available.

Parameters:

jbcEntityCache - The entity cache

jbcCollectionCache - the collection cache

jbcTsCache - The timestamps cache

jbcQueryCache - The query cache

           throws CacheException

Lifecycle callback to perform any necessary initialization of the CacheInstanceManager. Called exactly once during the construction of a SessionFactoryImpl.

Specified by:

start in interface CacheInstanceManager
