Class OrderedSynchronizationHandler

java.lang.Object
  org.jboss.cache.interceptors.OrderedSynchronizationHandler

All Implemented Interfaces:

javax.transaction.Synchronization

public class OrderedSynchronizationHandler
extends java.lang.Object
implements javax.transaction.Synchronization

Maintains a list of Synchronization handlers. Reason is that we have to invoke certain handlers before others. See the description in SyncTxUnitTestCase.testConcurrentPuts(). For example, for synchronous replication, we have to execute the ReplicationInterceptor's afterCompletion() before the TransactionInterceptor's.
