org.springframework.transaction

## Interface TransactionStatus

- All Superinterfaces:
    SavepointManager
  All Known Implementing Classes:
    AbstractTransactionStatus, DefaultTransactionStatus, SimpleTransactionStatus

      public interface TransactionStatus
      extends SavepointManager

  Representation of the status of a transaction.

  Transactional code can use this to retrieve status information, and to programmatically request a rollback (instead of throwing an exception that causes an implicit rollback).

  Derives from the SavepointManager interface to provide access to savepoint management facilities. Note that savepoint management is only available if supported by the underlying transaction manager.

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `flush()` Flush the underlying session to the datastore, if applicable: for example, all affected Hibernate/JPA sessions.
    `boolean` | `hasSavepoint()` Return whether this transaction internally carries a savepoint, that is, has been created as nested transaction based on a savepoint.
    `boolean` | `isCompleted()` Return whether this transaction is completed, that is, whether it has already been committed or rolled back.
    `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` | `isRollbackOnly()` Return whether the transaction has been marked as rollback-only (either by the application or by the transaction infrastructure).
    `void` | `setRollbackOnly()` Set the transaction rollback-only.

- - ### Method Detail

    - #### isNewTransaction

          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).

    - #### hasSavepoint

          boolean hasSavepoint()

      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 `isNewTransaction()`. For programmatic handling of custom savepoints, use SavepointManager's operations.

      See Also:
        `isNewTransaction()`, `SavepointManager.createSavepoint()`, `SavepointManager.rollbackToSavepoint(Object)`, `SavepointManager.releaseSavepoint(Object)`

    - #### setRollbackOnly

          void setRollbackOnly()

      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.

      See Also:
        `TransactionCallback.doInTransaction(org.springframework.transaction.TransactionStatus)`, `TransactionAttribute.rollbackOn(java.lang.Throwable)`

    - #### isRollbackOnly

          boolean isRollbackOnly()

      Return whether the transaction has been marked as rollback-only (either by the application or by the transaction infrastructure).

    - #### flush

          void flush()

      Flush the underlying session to the datastore, if applicable: for example, all affected Hibernate/JPA sessions.

    - #### isCompleted

          boolean isCompleted()

      Return whether this transaction is completed, that is, whether it has already been committed or rolled back.
