Class AlfrescoTransactionSupport

java.lang.Object

org.alfresco.util.transaction.TransactionSupportUtil

org.alfresco.repo.transaction.AlfrescoTransactionSupport

public abstract class AlfrescoTransactionSupport
extends org.alfresco.util.transaction.TransactionSupportUtil

Repo Specific Helper class to manage transaction synchronization. This provides helpers to ensure that the necessary TransactionSynchronization instances are registered on behalf of the application code.

This class remains for backward API compatibility, the majority of transaction support has been moved to TransactionSupportUtil in the Core project.

Method Detail

getTransactionReadState

public static AlfrescoTransactionSupport.TxnReadState getTransactionReadState()

Returns:

Returns the read-write state of the current transaction

Since:

2.1.4

checkTransactionReadState

public static void checkTransactionReadState(boolean requireReadWrite)

Checks the state of the current transaction and throws an exception if a transaction is not present or if the transaction is not read-write, if required.

Parameters:

requireReadWrite - true if the transaction must be read-write

Since:

3.2

isDirty

public static boolean isDirty()

Deprecated. To be replaced by DirtySessionMethodInterceptor

Are there any pending changes which must be synchronized with the store?

Returns:

true => changes are pending

bindDaoService

public static void bindDaoService(TransactionalDao daoService)

Method that registers a NodeDaoService against the transaction. Setting this will ensure that the pre- and post-commit operations perform the necessary cleanups against the NodeDaoService.

This method can be called repeatedly as long as the service being bound implements equals and hashCode.

Parameters:

daoService - TransactionalDao

bindIntegrityChecker

public static void bindIntegrityChecker(IntegrityChecker integrityChecker)

Method that registers an IntegrityChecker against the transaction. Setting this will ensure that the pre- and post-commit operations perform the necessary cleanups against the IntegrityChecker.

This method can be called repeatedly as long as the service being bound implements equals and hashCode.

Parameters:

integrityChecker - IntegrityChecker

bindLucene

public static void bindLucene(LuceneIndexerAndSearcher indexerAndSearcher)

Method that registers a LuceneIndexerAndSearcherFactory against the transaction.

Setting this will ensure that the pre- and post-commit operations perform the necessary cleanups against the LuceneIndexerAndSearcherFactory.

Although bound within a Set, it would still be better for the caller to only bind once per transaction, if possible.

Parameters:

indexerAndSearcher - the Lucene indexer to perform transaction completion tasks on

bindListener

public static void bindListener(TransactionListener listener)

Method maintained for backward compatibility: ACE-2801: Package change for TransactionListener.

See Also:

TransactionSupportUtil, bindListener(org.alfresco.util.transaction.TransactionListener)

bindListener

public static void bindListener(org.alfresco.util.transaction.TransactionListener listener)

Method that registers a Listener against the transaction.

will be better for the caller to only bind once per transaction, if possible.

Parameters:

listener - the transaction listener tasks on

Since:

5.0

flush

public static void flush()

Deprecated. No longer does anything

No-op
