Interface TransactionalWriter

All Superinterfaces:

javax.sql.RowSetWriter

All Known Implementing Classes:

CachedRowSetWriter

public interface TransactionalWriter

extends javax.sql.RowSetWriter

A specialized interface that facilitates an extension of the standard SyncProvider abstract class so that it has finer grained transaction control.

If one or more disconnected RowSet objects are particating in a global transaction, they may wish to coordinate their synchronization commits to preserve data integrity and reduce the number of sychronization exceptions. If this is the case, an application should set the CachedRowSet constant COMMIT_ON_ACCEPT_CHANGES to false and use the commit and rollback methods defined in this interface to manage transaction boundaries.

Method Summary

void	commit() Makes permanent all changes that have been performed by the acceptChanges method since the last call to either the commit or rollback methods.
void	rollback() Undoes all changes made in the current transaction.
void	rollback(java.sql.Savepoint s) Undoes all changes made in the current transaction made prior to the given Savepoint object.

Method Detail

commit

public void commit()
            throws java.sql.SQLException

Makes permanent all changes that have been performed by the acceptChanges method since the last call to either the commit or rollback methods. This method should be used only when auto-commit mode has been disabled.

Throws:

java.sql.SQLException - if a database access error occurs or the Connection object within this CachedRowSet object is in auto-commit mode

rollback

public void rollback()
              throws java.sql.SQLException

Undoes all changes made in the current transaction. This method should be used only when auto-commit mode has been disabled.

Throws:

java.sql.SQLException - if a database access error occurs or the Connection object within this CachedRowSet object is in auto-commit mode

rollback

public void rollback(java.sql.Savepoint s)
              throws java.sql.SQLException

Undoes all changes made in the current transaction made prior to the given Savepoint object. This method should be used only when auto-commit mode has been disabled.

Parameters:

s - a Savepoint object marking a savepoint in the current transaction. All changes made before s was set will be undone. All changes made after s was set will be made permanent.

Throws:

java.sql.SQLException - if a database access error occurs or the Connection object within this CachedRowSet object is in auto-commit mode
