Hi Fabio,
That's not exactly what I meant. I want to determine if the property
is dirty before I flush the object/session.
But I found a solution that works for me. Can you tell me if it's save
to do it that way?
My solution:
public bool IsDirtyProperty(IEntity entity, string
propertyName)
{
// Find the className of the Poco object
string className = entity.GetType().FullName;
if (entity is INHibernateProxy)
{
className = entity.GetType().BaseType.FullName;
}
ISessionImplementor session =
_Session.GetSessionImplementation();
IPersistenceContext persistenceContext =
session.PersistenceContext;
IEntityPersister persister =
session.Factory.GetEntityPersister(className);
EntityKey keyToLoad = new EntityKey(entity.ObjectIdentity,
persister, session.EntityMode);
object obj = session.GetEntityUsingInterceptor(keyToLoad);
EntityEntry oldEntry = session.PersistenceContext.GetEntry
(obj);
object[] oldState = oldEntry.LoadedState;
object[] currentState = persister.GetPropertyValues(obj,
session.EntityMode);
int[] dirtyProps = persister.FindDirty(currentState,
oldState, obj, session);
// Find the index of the propertyName
int index = Array.IndexOf(persister.PropertyNames,
propertyName);
// Check if the index is in the dirtyProps array
bool isDirty = Array.IndexOf(dirtyProps, index) != -1;
return isDirty;
}
Best regards,
Harm.
