## org.springframework.transaction.support
Class AbstractTransactionStatus

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

All Implemented Interfaces:
  SavepointManager, TransactionStatus

Direct Known Subclasses:
  DefaultTransactionStatus, SimpleTransactionStatus

    public abstract class AbstractTransactionStatus

extends Object
implements TransactionStatus

Abstract base implementation of the `TransactionStatus` interface.

Pre-implements the handling of local rollback-only and completed flags, and delegation to an underlying `SavepointManager`. Also offers the option of a holding a savepoint within the transaction.

Does not assume any specific internal transaction handling, such as an underlying transaction object, and no transaction synchronization mechanism.

Since:
  1.2.3

  Juergen Hoeller

Constructor Detail

### AbstractTransactionStatus

    public AbstractTransactionStatus()

Method Detail

### setRollbackOnly

    public void setRollbackOnly()

  Description copied from interface: `TransactionStatus`
  Set the transaction rollback-only. This instructs the transaction manager that the only possible outcome of the transaction may be a rollback, as alternative to throwing an exception which would in turn trigger a rollback.

  This is mainly intended for transactions managed by `TransactionTemplate` or `TransactionInterceptor`, where the actual commit/rollback decision is made by the container.

  Specified by:
    `setRollbackOnly` in interface `TransactionStatus`
  See Also:
    `TransactionCallback.doInTransaction(org.springframework.transaction.TransactionStatus)`, `TransactionAttribute.rollbackOn(java.lang.Throwable)`

### isRollbackOnly

    public boolean isRollbackOnly()

  Determine the rollback-only flag via checking both the local rollback-only flag of this TransactionStatus and the global rollback-only flag of the underlying transaction, if any.

  Specified by:
    `isRollbackOnly` in interface `TransactionStatus`
  See Also:
    `isLocalRollbackOnly()`, `isGlobalRollbackOnly()`

### isLocalRollbackOnly

    public boolean isLocalRollbackOnly()

  Determine the rollback-only flag via checking this TransactionStatus.

  Will only return "true" if the application called `setRollbackOnly` on this TransactionStatus object.

### isGlobalRollbackOnly

    public boolean isGlobalRollbackOnly()

  Template method for determining the global rollback-only flag of the underlying transaction, if any.

  This implementation always returns `false`.

### flush

    public void flush()

  This implementations is empty, considering flush as a no-op.

  Specified by:
    `flush` in interface `TransactionStatus`

### setCompleted

    public void setCompleted()

  Mark this transaction as completed, that is, committed or rolled back.

### isCompleted

    public boolean isCompleted()

  Description copied from interface: `TransactionStatus`
  Return whether this transaction is completed, that is, whether it has already been committed or rolled back.

  Specified by:
    `isCompleted` in interface `TransactionStatus`
  See Also:
    `PlatformTransactionManager.commit(org.springframework.transaction.TransactionStatus)`, `PlatformTransactionManager.rollback(org.springframework.transaction.TransactionStatus)`

### setSavepoint

    protected void setSavepoint(Object savepoint)

  Set a savepoint for this transaction. Useful for PROPAGATION_NESTED.

  See Also:
    `TransactionDefinition.PROPAGATION_NESTED`

### getSavepoint

    protected Object getSavepoint()

  Get the savepoint for this transaction, if any.

### hasSavepoint

    public boolean hasSavepoint()

  Description copied from interface: `TransactionStatus`
  Return whether this transaction internally carries a savepoint, that is, has been created as nested transaction based on a savepoint.

  This method is mainly here for diagnostic purposes, alongside `TransactionStatus.isNewTransaction()`. For programmatic handling of custom savepoints, use SavepointManager's operations.

  Specified by:
    `hasSavepoint` in interface `TransactionStatus`
  See Also:
    `TransactionStatus.isNewTransaction()`, `SavepointManager.createSavepoint()`, `SavepointManager.rollbackToSavepoint(Object)`, `SavepointManager.releaseSavepoint(Object)`

### createAndHoldSavepoint

    public void createAndHoldSavepoint()
                                throws TransactionException

  Create a savepoint and hold it for the transaction.

  Throws:
    `NestedTransactionNotSupportedException` - if the underlying transaction does not support savepoints
    `TransactionException`

### rollbackToHeldSavepoint

    public void rollbackToHeldSavepoint()
                                 throws TransactionException

  Roll back to the savepoint that is held for the transaction.

  Throws:
    `TransactionException`

### releaseHeldSavepoint

    public void releaseHeldSavepoint()
                              throws TransactionException

  Release the savepoint that is held for the transaction.

  Throws:
    `TransactionException`

### createSavepoint

    public Object createSavepoint()
                           throws TransactionException

  This implementation delegates to a SavepointManager for the underlying transaction, if possible.

  Specified by:
    `createSavepoint` in interface `SavepointManager`
  Returns:
    a savepoint object, to be passed into rollbackToSavepoint or releaseSavepoint
  Throws:
    `NestedTransactionNotSupportedException` - if the underlying transaction does not support savepoints
    `TransactionException` - if the savepoint could not be created, for example because the transaction is not in an appropriate state
  See Also:
    `getSavepointManager()`, `SavepointManager`

### rollbackToSavepoint

    public void rollbackToSavepoint(Object savepoint)
                             throws TransactionException

  This implementation delegates to a SavepointManager for the underlying transaction, if possible.

  Specified by:
    `rollbackToSavepoint` in interface `SavepointManager`
  Parameters:
    `savepoint` - the savepoint to roll back to
  Throws:
    `NestedTransactionNotSupportedException`
    `TransactionException` - if the rollback failed
  See Also:
    `getSavepointManager()`, `SavepointManager`

### releaseSavepoint

    public void releaseSavepoint(Object savepoint)
                          throws TransactionException

  This implementation delegates to a SavepointManager for the underlying transaction, if possible.

  Specified by:
    `releaseSavepoint` in interface `SavepointManager`
  Parameters:
    `savepoint` - the savepoint to release
  Throws:
    `NestedTransactionNotSupportedException` - if the underlying transaction does not support savepoints
    `TransactionException` - if the release failed
  See Also:
    `getSavepointManager()`, `SavepointManager`

### getSavepointManager

    protected SavepointManager getSavepointManager()

  Return a SavepointManager for the underlying transaction, if possible.

  Default implementation always throws a NestedTransactionNotSupportedException.

  Throws:
    `NestedTransactionNotSupportedException` - if the underlying transaction does not support savepoints
