Class DefaultTransactionStatus

java.lang.Object
  org.springframework.transaction.support.AbstractTransactionStatus
      org.springframework.transaction.support.DefaultTransactionStatus

All Implemented Interfaces:

SavepointManager, TransactionStatus

public class DefaultTransactionStatus
extends AbstractTransactionStatus

Default implementation of the TransactionStatus interface, used by AbstractPlatformTransactionManager. Based on the concept of an underlying "transaction object".

Holds all status information that AbstractPlatformTransactionManager needs internally, including a generic transaction object determined by the concrete transaction manager implementation.

Supports delegating savepoint-related methods to a transaction object that implements the SavepointManager interface.

NOTE: This is not intended to be used for other PlatformTransactionManager implementations, in particular not for mock transaction managers. Use SimpleTransactionStatus or a mock for the plain TransactionStatus interface instead.

Constructor Summary

DefaultTransactionStatus(Object transaction, boolean newTransaction, boolean newSynchronization, boolean readOnly, boolean debug, Object suspendedResources)
Create a new DefaultTransactionStatus instance.

Method Summary

protected SavepointManager	getSavepointManager() This implementation exposes the SavepointManager interface of the underlying transaction object, if any.
Object	getSuspendedResources() Return the holder for resources that have been suspended for this transaction, if any.
Object	getTransaction() Return the underlying transaction object.
boolean	hasTransaction() Return whether there is an actual transaction active.
boolean	isDebug() Return whether the progress of this transaction is debugged.
boolean	isGlobalRollbackOnly() Determine the rollback-only flag via checking both the transaction object, provided that the latter implements the SmartTransactionObject interface.
boolean	isNewSynchronization() Return if a new transaction synchronization has been opened for this transaction.
boolean	isNewTransaction() Return whether the present transaction is new (else participating in an existing transaction, or potentially not running in an actual transaction in the first place).
boolean	isReadOnly() Return if this transaction is defined as read-only transaction.
boolean	isTransactionSavepointManager() Return whether the underlying transaction implements the SavepointManager interface.

Constructor Detail

DefaultTransactionStatus

public DefaultTransactionStatus(Object transaction,
                                boolean newTransaction,
                                boolean newSynchronization,
                                boolean readOnly,
                                boolean debug,
                                Object suspendedResources)

Create a new DefaultTransactionStatus instance.

Parameters:

transaction - underlying transaction object that can hold state for the internal transaction implementation

newTransaction - if the transaction is new, else participating in an existing transaction

newSynchronization - if a new transaction synchronization has been opened for the given transaction

readOnly - whether the transaction is read-only

debug - should debug logging be enabled for the handling of this transaction? Caching it in here can prevent repeated calls to ask the logging system whether debug logging should be enabled.

suspendedResources - a holder for resources that have been suspended for this transaction, if any

Method Detail

getTransaction

public Object getTransaction()

Return the underlying transaction object.

hasTransaction

public boolean hasTransaction()

Return whether there is an actual transaction active.

isNewTransaction

public boolean isNewTransaction()

Description copied from interface: TransactionStatus

Return whether the present transaction is new (else participating in an existing transaction, or potentially not running in an actual transaction in the first place).

isNewSynchronization

public boolean isNewSynchronization()

Return if a new transaction synchronization has been opened for this transaction.

isReadOnly

public boolean isReadOnly()

Return if this transaction is defined as read-only transaction.

isDebug

public boolean isDebug()

Return whether the progress of this transaction is debugged. This is used by AbstractPlatformTransactionManager as an optimization, to prevent repeated calls to logger.isDebug(). Not really intended for client code.

getSuspendedResources

public Object getSuspendedResources()

Return the holder for resources that have been suspended for this transaction, if any.

isGlobalRollbackOnly

public boolean isGlobalRollbackOnly()

Determine the rollback-only flag via checking both the transaction object, provided that the latter implements the SmartTransactionObject interface.

Will return "true" if the transaction itself has been marked rollback-only by the transaction coordinator, for example in case of a timeout.

Overrides:

isGlobalRollbackOnly in class AbstractTransactionStatus

See Also:

SmartTransactionObject.isRollbackOnly()

getSavepointManager

protected SavepointManager getSavepointManager()

This implementation exposes the SavepointManager interface of the underlying transaction object, if any.

Overrides:

getSavepointManager in class AbstractTransactionStatus

isTransactionSavepointManager

public boolean isTransactionSavepointManager()

Return whether the underlying transaction implements the SavepointManager interface.

getTransaction(), SavepointManager
