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

Example 1 with LoadEvent

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

the class SessionImpl method load.

// load()/get() operations ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
@Override
public void load(Object object, Serializable id) throws HibernateException {
    LoadEvent event = loadEvent;
    loadEvent = null;
    if (event == null) {
        event = new LoadEvent(id, object, this);
    } else {
        event.setEntityClassName(null);
        event.setEntityId(id);
        event.setInstanceToLoad(object);
        event.setLockMode(LoadEvent.DEFAULT_LOCK_MODE);
        event.setLockScope(LoadEvent.DEFAULT_LOCK_OPTIONS.getScope());
        event.setLockTimeout(LoadEvent.DEFAULT_LOCK_OPTIONS.getTimeOut());
    }
    fireLoad(event, LoadEventListener.RELOAD);
    if (loadEvent == null) {
        event.setEntityClassName(null);
        event.setEntityId(null);
        event.setInstanceToLoad(null);
        event.setResult(null);
        loadEvent = event;
    }
}

Example 2 with LoadEvent

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

the class SessionImpl method internalLoad.

@Override
public final Object internalLoad(String entityName, Serializable id, boolean eager, boolean nullable) throws HibernateException {
    // todo : remove
    LoadEventListener.LoadType type = nullable ? LoadEventListener.INTERNAL_LOAD_NULLABLE : eager ? LoadEventListener.INTERNAL_LOAD_EAGER : LoadEventListener.INTERNAL_LOAD_LAZY;
    LoadEvent event = loadEvent;
    loadEvent = null;
    event = recycleEventInstance(event, id, entityName);
    fireLoad(event, type);
    Object result = event.getResult();
    if (!nullable) {
        UnresolvableObjectException.throwIfNull(result, id, entityName);
    }
    if (loadEvent == null) {
        event.setEntityClassName(null);
        event.setEntityId(null);
        event.setInstanceToLoad(null);
        event.setResult(null);
        loadEvent = event;
    }
    return result;
}

Example 3 with LoadEvent

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

the class SessionImpl method immediateLoad.

/**
 * Load the data for the object with the specified id into a newly created object.
 * This is only called when lazily initializing a proxy.
 * Do NOT return a proxy.
 */
@Override
public Object immediateLoad(String entityName, Serializable id) throws HibernateException {
    if (log.isDebugEnabled()) {
        EntityPersister persister = getFactory().getMetamodel().entityPersister(entityName);
        log.debugf("Initializing proxy: %s", MessageHelper.infoString(persister, id, getFactory()));
    }
    LoadEvent event = loadEvent;
    loadEvent = null;
    event = recycleEventInstance(event, id, entityName);
    fireLoad(event, LoadEventListener.IMMEDIATE_LOAD);
    Object result = event.getResult();
    if (loadEvent == null) {
        event.setEntityClassName(null);
        event.setEntityId(null);
        event.setInstanceToLoad(null);
        event.setResult(null);
        loadEvent = event;
    }
    return result;
}
