Interface Transaction

All Known Implementing Classes:: JDBCTransaction, JTATransaction

public interface Transaction

Allows the application to define units of work, while maintaining abstraction from the underlying transaction implementation (eg. JTA, JDBC).

A transaction is associated with a Session and is usually instantiated by a call to Session.beginTransaction(). A single session might span multiple transactions since the notion of a session (a conversation between the application and the datastore) is of coarser granularity than the notion of a transaction. However, it is intended that there be at most one uncommitted Transaction associated with a particular Session at any time.

Implementors are not intended to be threadsafe.

Force the underlying transaction to roll back.
