public abstract class JdbcTransactionObjectSupport extends Object implements SavepointManager, SmartTransactionObject
ConnectionHolder
with a JDBC Connection
, and implements the
SavepointManager
interface based on that ConnectionHolder
.
Allows for programmatic management of JDBC Savepoints
.
Spring's DefaultTransactionStatus
automatically delegates to this, as it autodetects transaction objects which
implement the SavepointManager
interface.
