I am trying to port some code to NHibernate 1.2.0.CR1 and I have to update a custom user type I created. There are 3 new methods that are required: Replace, Assemble, and Disassemble. Are there any examples to show what logic to put in these methods?

XML comments of IUserType say what the default implementation can do. You can also look at the NHibernate sources to look how standard NH types are implemented.

Thanks. I did read the source comments before I posted, but I guess it was not so obvious to me. I ended up using the following:

Code:

public object Replace(object original, object target, object owner)
{
    return DeepCopy(original);
}
public object Assemble(object cached, object owner)
{
    return DeepCopy(cached);
}
public object Disassemble(object value)
{
    return DeepCopy(value);
}

I used the code from BFileType.cs in NHibernate.UserTypes.Oracle as an example.
