org.springframework.orm.toplink
Class SessionBrokerSessionFactory

java.lang.Object
  org.springframework.orm.toplink.AbstractSessionFactory
      org.springframework.orm.toplink.SessionBrokerSessionFactory

All Implemented Interfaces:: SessionFactory

public class SessionBrokerSessionFactory
extends AbstractSessionFactory
extends AbstractSessionFactory

Spring SessionFactory implementation allowing users to inject a TopLink Session built from a TopLink SessionBroker. SessionBrokers are used identically to any other TopLink Session. DAO code should never have to distinguish between Sessions which broker requests to multiple databases and Sessions which manage requests to a single database. The only pertinent difference in the SessionBroker api involves the method for obtaining a thread-safe "client" Session from the SessionBroker. Instead of the typical acquireClientSession method, this SessionFactory implementation uses the acquireClientSessionBroker method. If a SessionBroker aggregates non thread-safe DatabaseSessions, the factory will throw UnsupportedOperationExceptions if used to create managed or transaction-aware Sessions.

Since:: 1.2.6
