Examples of org.objectweb.speedo.pm.api.POManagerItf

org.objectweb.speedo.pm.api.POManagerItf
defines a manager of persistent instance. A POManagerItf is a javax.transaction.Synchronization for the JTA integration. This permits to support the container transaction demarcation. On the beforeCompletion method the perseus transaction is prepared. A po manager used a TransactionalPersistenceManager for managing the concurrency, the loading and the caching aspects. @see org.objectweb.speedo.pm.api.POManagerFactoryItf @see org.objectweb.speedo.pm.api.POManagerSwitchItf @see org.objectweb.perseus.persistence.api.TransactionalPersistenceManager @author S.Chassande-Barrioz

     * @param sp a speedo po instance.
     * @exception SpeedoRuntimeException if the instance is managed by
