Setting ModifiedDate

[epitka]

How would one go about updating a ModifiedDate and CreatedDate columns
if I do not want to expose setters on my class. So when record is
being persisted it should NH should auto set these two properties to
Now() and so that ModifiedDate is always updated and CreatedDate only
when record is new. Is there a way to do that.

I know I can write interceptors etc. but I do not want these to have
setters at all.

Write interceptor it doesn't need a setter :)

With the interceptor you can:

public class MyInterceptor : EmptyInterceptor
{
public override bool OnFlushDirty(object entity, object id, object[]
currentState, object[] previousState, string[] propertyNames, IType[]
types)
{
int md = FindProperty("ModifiedDate", propertyNames);
if(md >= 0)
currentState[i] = DateTime.Now; //or via IoC
}

public override bool OnSave(object entity, object id, object[] state,
string[] propertyNames, IType[] types)
{
int md = FindProperty("CreatedDate", propertyNames);
if(md >= 0)
state[i] = DateTime.Now; //or via IoC

}

private static int FindProperty(string property, string[] propertyNames)
{
for (int i = 0; i < propertyNames.Length; i++)
{
if (propertyNames[i] == property)
return i;
}
return -1;

I wondered if there was a way to specify something like that through
the mapping.
