Interface TransactionalWriter
- 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.
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(Savepoint s)- Undoes all changes made in the current transaction made prior to the given
Savepoint object.
|
commit
public void commit()
throws 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.
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 SQLException Undoes all changes made in the current transaction. This method should be
used only when auto-commit mode has been disabled.
SQLException - if a database access error occurs or the Connection
object within this CachedRowSet object is in auto-commit mode
rollback
public void rollback(Savepoint s)
throws 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.
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.
SQLException - if a database access error occurs or the Connection
object within this CachedRowSet object is in auto-commit mode
