public interface TransactionalWriter extends 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.
