org.jboss.cache.interceptors
Class OrderedSynchronizationHandler

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

All Implemented Interfaces:: Synchronization (src)

public class OrderedSynchronizationHandler
extends java.lang.Object
implements Synchronization (src)

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.

Method Summary
`void`	`afterCompletion(int status)` This method is invoked after the transaction has committed or rolled back.
`void`	`beforeCompletion()` This method is invoked before the start of the commit process.
`static OrderedSynchronizationHandler (src)`	`getInstance(Transaction (src) tx)` Creates a new instance of OrderedSynchronizationHandler, or fetches an existing instance.
`void`	`registerAtHead(Synchronization (src) handler)`
`void`	`registerAtTail(Synchronization (src) handler)`
`java.lang.String`	`toString()`

Method Detail

getInstance

public static OrderedSynchronizationHandler (src)  getInstance(Transaction (src)  tx)
                                                 throws SystemException (src) ,

Creates a new instance of OrderedSynchronizationHandler, or fetches an existing instance. Key is the local transaction (tx). This instance registers with the TransactionManager automatically

Parameters:: tx -
Returns:
Throws:: SystemException (src); RollbackException (src)

registerAtHead

public void registerAtHead(Synchronization (src)  handler)

registerAtTail

public void registerAtTail(Synchronization (src)  handler)

beforeCompletion

public void beforeCompletion()

Description copied from interface: Synchronization (src)
