Hi,
Object state stored in IEntityPersister, check LoadedState for loaded state.
Current state you can get from object with method GetPropertyValue.
Below code sample for detecting if property changed:
public static bool IsChanged<T>(this ISession session, T entity, string
property) { var entry = session.GetEntry(entity); if (entry == null) return
true; var index = entry.Persister.PropertyNames.IndexOf(n =>
n.Equals(property, StringComparison.OrdinalIgnoreCase)); var currentState =
entry.Persister.GetPropertyValue(entity, index, session.ActiveEntityMode);
if (entry.LoadedState != null) return !Equals(currentState,
entry.LoadedState[index]); return true; }
private static EntityEntry GetEntry(this ISession s, object activeRecord) {
var context = s.GetSessionImplementation().PersistenceContext; EntityEntry
entry; var proxy = activeRecord as INHibernateProxy; if (proxy != null) {
if (!context.ContainsProxy(proxy)) throw new
TransientObjectException("proxy was not associated with the session"); var
li = proxy.HibernateLazyInitializer; entry =
context.GetEntry(li.GetImplementation()); } else { entry =
context.GetEntry(activeRecord); } return entry; }
