org.springframework.transaction .SavepointManager

All known Subclasses:   org.springframework.jdbc.datasource .JdbcTransactionObjectSupport,
SavepointManager
public interface SavepointManager (Code)
Interface that specifies an API to programmatically manage transaction savepoints in a generic fashion. Extended by TransactionStatus to expose savepoint management functionality for a specific transaction.
Note that savepoints can only work within an active transaction. Just use this programmatic savepoint handling for advanced needs; else, a subtransaction with PROPAGATION_NESTED is preferable.
This interface is inspired by JDBC 3.0's Savepoint mechanism but is independent from any specific persistence technology.

Method Summary
Object createSavepoint()
     Create a new savepoint.
void releaseSavepoint(Object savepoint)
     Explicitly release the given savepoint.
void rollbackToSavepoint(Object savepoint)
     Roll back to the given savepoint.

Method Detail
createSavepoint
Object createSavepoint() throws TransactionException(Code)
Create a new savepoint. You can roll back to a specific savepoint via rollbackToSavepoint, and explicitly release a savepoint that you don't need anymore via releaseSavepoint.
Note that most transaction managers will automatically release savepoints at transaction completion. a savepoint object, to be passed into rollbackToSavepointor releaseSavepoint
throws:
  NestedTransactionNotSupportedException - if the underlyingtransaction does not support savepoints
throws:
  TransactionException - if the savepoint could not be created,for example because the transaction is not in an appropriate state
See Also:   java.sql.Connection.setSavepoint

releaseSavepoint
void releaseSavepoint(Object savepoint) throws TransactionException(Code)
Explicitly release the given savepoint.
Note that most transaction managers will automatically release savepoints at transaction completion.
Implementations should fail as silently as possible if proper resource cleanup will still happen at transaction completion.
Parameters:
  savepoint - the savepoint to release
throws:
  NestedTransactionNotSupportedException - if the underlyingtransaction does not support savepoints
throws:
  TransactionException - if the release failed
See Also:   java.sql.Connection.releaseSavepoint

rollbackToSavepoint
void rollbackToSavepoint(Object savepoint) throws TransactionException(Code)
Roll back to the given savepoint. The savepoint will be automatically released afterwards.
Parameters:
  savepoint - the savepoint to roll back to
throws:
  NestedTransactionNotSupportedException - if the underlyingtransaction does not support savepoints
throws:
  TransactionException - if the rollback failed
See Also:   java.sql.Connection.rollback(java.sql.Savepoint)
