All Implemented Interfaces:
Flushable, Ordered, TransactionSynchronization
Direct Known Subclasses:
SpringFlushSynchronization, SpringFlushSynchronization, SpringLobCreatorSynchronization
```
public abstract class TransactionSynchronizationAdapter
extends Object
implements TransactionSynchronization, Ordered
```
Simple TransactionSynchronization adapter containing empty method implementations, for easier overriding of single methods.
Also implements the Ordered interface to enable the execution order of synchronizations to be controlled declaratively. The default order is Ordered.LOWEST_PRECEDENCE, indicating late execution; return a lower value for earlier execution.

public TransactionSynchronizationAdapter()
```
- Method Detail
  - getOrder
```
public int getOrder()
```
    Description copied from interface: Ordered
    Get the order value of this object.
    Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet load-on-startup values).
    Same order values will result in arbitrary sort positions for the affected objects.
    Specified by:
    getOrder in interface Ordered
    Returns:
    the order value
    See Also:
    Ordered.HIGHEST_PRECEDENCE, Ordered.LOWEST_PRECEDENCE
  - suspend
```
public void suspend()
```
    Description copied from interface: TransactionSynchronization
    Suspend this synchronization. Supposed to unbind resources from TransactionSynchronizationManager if managing any.
    Specified by:
    suspend in interface TransactionSynchronization
    See Also:
    TransactionSynchronizationManager.unbindResource(java.lang.Object)
  - resume
```
public void resume()
```
    Description copied from interface: TransactionSynchronization
    Resume this synchronization. Supposed to rebind resources to TransactionSynchronizationManager if managing any.
    Specified by:
    resume in interface TransactionSynchronization
    See Also:
    TransactionSynchronizationManager.bindResource(java.lang.Object, java.lang.Object)
  - flush
```
public void flush()
```
    Description copied from interface: TransactionSynchronization
    Flush the underlying session to the datastore, if applicable: for example, a Hibernate/JPA session.
    Specified by:
    flush in interface Flushable
    Specified by:
    flush in interface TransactionSynchronization
    See Also:
    TransactionStatus.flush()
  - beforeCommit
```
public void beforeCommit(boolean readOnly)
```
    Description copied from interface: TransactionSynchronization
    Invoked before transaction commit (before "beforeCompletion"). Can e.g. flush transactional O/R Mapping sessions to the database.
    This callback does not mean that the transaction will actually be committed. A rollback decision can still occur after this method has been called. This callback is rather meant to perform work that's only relevant if a commit still has a chance to happen, such as flushing SQL statements to the database.
    Note that exceptions will get propagated to the commit caller and cause a rollback of the transaction.
    Specified by:
    beforeCommit in interface TransactionSynchronization
    Parameters:
    readOnly - whether the transaction is defined as read-only transaction
    See Also:
    TransactionSynchronization.beforeCompletion()
  - beforeCompletion
```
public void beforeCompletion()
```
    Description copied from interface: TransactionSynchronization
    Invoked before transaction commit/rollback. Can perform resource cleanup before transaction completion.
    This method will be invoked after beforeCommit, even when beforeCommit threw an exception. This callback allows for closing resources before transaction completion, for any outcome.
    Specified by:
    beforeCompletion in interface TransactionSynchronization
    See Also:
    TransactionSynchronization.beforeCommit(boolean), TransactionSynchronization.afterCompletion(int)
  - afterCommit
```
public void afterCommit()
```
    Description copied from interface: TransactionSynchronization
    Invoked after transaction commit. Can perform further operations right after the main transaction has successfully committed.
    Can e.g. commit further operations that are supposed to follow on a successful commit of the main transaction, like confirmation messages or emails.
    NOTE: The transaction will have been committed already, but the transactional resources might still be active and accessible. As a consequence, any data access code triggered at this point will still "participate" in the original transaction, allowing to perform some cleanup (with no commit following anymore!), unless it explicitly declares that it needs to run in a separate transaction. Hence: Use PROPAGATION_REQUIRES_NEW for any transactional operation that is called from here.
    Specified by:
    afterCommit in interface TransactionSynchronization
  - afterCompletion
```
public void afterCompletion(int status)
```
    Description copied from interface: TransactionSynchronization
    Invoked after transaction commit/rollback. Can perform resource cleanup after transaction completion.
    NOTE: The transaction will have been committed or rolled back already, but the transactional resources might still be active and accessible. As a consequence, any data access code triggered at this point will still "participate" in the original transaction, allowing to perform some cleanup (with no commit following anymore!), unless it explicitly declares that it needs to run in a separate transaction. Hence: Use PROPAGATION_REQUIRES_NEW for any transactional operation that is called from here.
    Specified by:
    afterCompletion in interface TransactionSynchronization
    Parameters:
    status - completion status according to the STATUS_* constants
    See Also:
    TransactionSynchronization.STATUS_COMMITTED, TransactionSynchronization.STATUS_ROLLED_BACK, TransactionSynchronization.STATUS_UNKNOWN, TransactionSynchronization.beforeCompletion()
