Examples with EntityCopyObserver org.hibernate.event.spi.EntityCopyObserver used on opensource projects

Example 1 with EntityCopyObserver

use of org.hibernate.event.spi.EntityCopyObserver in project hibernate-orm by hibernate.

the class DefaultMergeEventListener method onMerge.

/**
 * Handle the given merge event.
 *
 * @param event The merge event to be handled.
 */
public void onMerge(MergeEvent event) throws HibernateException {
    final EntityCopyObserver entityCopyObserver = createEntityCopyObserver(event.getSession().getFactory());
    final MergeContext mergeContext = new MergeContext(event.getSession(), entityCopyObserver);
    try {
        onMerge(event, mergeContext);
        entityCopyObserver.topLevelMergeComplete(event.getSession());
    } finally {
        entityCopyObserver.clear();
        mergeContext.clear();
    }
}

Example 2 with EntityCopyObserver

use of org.hibernate.event.spi.EntityCopyObserver in project hibernate-orm by hibernate.

the class EntityCopyObserverFactoryInitiator method initiateService.

@Override
public EntityCopyObserverFactory initiateService(final Map<String, Object> configurationValues, final ServiceRegistryImplementor registry) {
    final Object value = getConfigurationValue(configurationValues);
    if (value.equals(EntityCopyNotAllowedObserver.SHORT_NAME) || value.equals(EntityCopyNotAllowedObserver.class.getName())) {

        return EntityCopyNotAllowedObserver.FACTORY_OF_SELF;
    } else if (value.equals(EntityCopyAllowedObserver.SHORT_NAME) || value.equals(EntityCopyAllowedObserver.class.getName())) {

        return EntityCopyAllowedLoggedObserver.FACTORY_OF_SELF;
    } else {
        // We load an "example instance" just to get its Class;
        // this might look excessive, but it also happens to test eagerly (at boot) that we can actually construct these
        // and that they are indeed of the right type.
        EntityCopyObserver exampleInstance = registry.getService(StrategySelector.class).resolveStrategy(EntityCopyObserver.class, value);
        Class<?> observerType = exampleInstance.getClass();
        LOG.debugf("Configured EntityCopyObserver is a custom implementation of type %s", observerType.getName());
        return new EntityObserversFactoryFromClass(observerType);
    }
}

Example 3 with EntityCopyObserver

use of org.hibernate.event.spi.EntityCopyObserver in project hibernate-reactive by hibernate.
