  extended by org.alfresco.repo.transaction.DummyTransactionService
All Implemented Interfaces:
TransactionService

public class DummyTransactionService
extends java.lang.Object
implements TransactionService

Simple implementation of the transaction service that serve up entirely useless user transactions. It is useful within the context of some tests.

Constructor Detail

DummyTransactionService

public DummyTransactionService()
Method Detail

getAllowWrite

public boolean getAllowWrite()
Description copied from interface: TransactionService
Determine if the repository has been put into read only mode. This is independent of the current user.

Specified by:
getAllowWrite in interface TransactionService
Returns:
true if the repository is allowed to perform write operations

isReadOnly

public boolean isReadOnly()
Description copied from interface: TransactionService
Determine if ALL user transactions will be read-only. The 'System' user is always allowed to write.

Specified by:
isReadOnly in interface TransactionService
Returns:
Returns true if all transactions are read-only AND the current user is not the 'System' user.

getUserTransaction

public javax.transaction.UserTransaction getUserTransaction()
Description copied from interface: TransactionService
Gets a user transaction that supports transaction propagation. This is like the EJB REQUIRED transaction attribute.

Specified by:
getUserTransaction in interface TransactionService
Returns:
the user transaction

getUserTransaction

public javax.transaction.UserTransaction getUserTransaction(boolean readOnly)
Description copied from interface: TransactionService
Gets a user transaction that supports transaction propagation. This is like the EJB REQUIRED transaction attribute.

Specified by:
getUserTransaction in interface TransactionService
Parameters:
readOnly - Set true for a READONLY transaction instance, false otherwise. Note that it is not always possible to force a write transaction if the system is in read-only mode.
Returns:
the user transaction

getUserTransaction

public javax.transaction.UserTransaction getUserTransaction(boolean readOnly,
                                                            boolean ignoreSystemReadOnly)
Description copied from interface: TransactionService
Gets a user transaction that supports transaction propagation. This is like the EJB REQUIRED transaction attribute.

Specified by:
getUserTransaction in interface TransactionService
Parameters:
readOnly - Set true for a READONLY transaction instance, false otherwise.
ignoreSystemReadOnly - true to force the read-only flag to be respected regardless of the system read-only mode.
Returns:
the user transaction

getNonPropagatingUserTransaction

public javax.transaction.UserTransaction getNonPropagatingUserTransaction()
Description copied from interface: TransactionService
Gets a user transaction that ensures a new transaction is created. Any enclosing transaction is not propagated. This is like the EJB REQUIRES_NEW transaction attribute - when the transaction is started, the current transaction will be suspended and a new one started.

Specified by:
getNonPropagatingUserTransaction in interface TransactionService
Returns:
Returns a non-propagating user transaction

getNonPropagatingUserTransaction

public javax.transaction.UserTransaction getNonPropagatingUserTransaction(boolean readOnly)
Description copied from interface: TransactionService
Gets a user transaction that ensures a new transaction is created. Any enclosing transaction is not propagated. This is like the EJB REQUIRES_NEW transaction attribute - when the transaction is started, the current transaction will be suspended and a new one started.

Specified by:
getNonPropagatingUserTransaction in interface TransactionService
Parameters:
readOnly - Set true for a READONLY transaction instance, false otherwise. Note that it is not always possible to force a write transaction if the system is in read-only mode.
Returns:
Returns a non-propagating user transaction

getNonPropagatingUserTransaction

public javax.transaction.UserTransaction getNonPropagatingUserTransaction(boolean readOnly,
                                                                          boolean ignoreSystemReadOnly)
Description copied from interface: TransactionService
Gets a user transaction that ensures a new transaction is created. Any enclosing transaction is not propagated. This is like the EJB REQUIRES_NEW transaction attribute - when the transaction is started, the current transaction will be suspended and a new one started.

Specified by:
getNonPropagatingUserTransaction in interface TransactionService
Parameters:
readOnly - Set true for a READONLY transaction instance, false otherwise.
ignoreSystemReadOnly - true to force the read-only flag to be respected regardless of the system read-only mode.
Returns:
Returns a non-propagating user transaction

getRetryingTransactionHelper

public RetryingTransactionHelper getRetryingTransactionHelper()
Description copied from interface: TransactionService
Get the standard instance of the helper object that supports transaction retrying.

Specified by:
getRetryingTransactionHelper in interface TransactionService
Returns:
Returns a helper object that executes units of work transactionally. The helper can be reused or altered as required.
