Re: Mapping rewrite

Runtime in this context means _before_ we call BuildSessionFactory, but
without touching the source XML files.
Ideally, I want to be able to run this at some point at the config build
lifetime:

PersistentClass classMapping = cfg.GetClassMapping(userType);
foreach (PersistentClass persistentClass in cfg.ClassMappings)
{
    //ignore non Rhino Security entities
    if (persistentClass.MappedClass.Assembly != typeof(IUser).Assembly)
        continue;

    foreach (Property property in persistentClass.PropertyIterator)
    {
        ManyToOne manyToOne = property.Value as ManyToOne;
        if (manyToOne == null || manyToOne.ReferencedEntityName !=
typeof(IUser).FullName)
            continue;
        ManyToOne value = new ManyToOne(classMapping.Table);
        value.ReferencedEntityName = userType.FullName;
        foreach (ISelectable selectable in manyToOne.ColumnIterator)
        {
            Column col = selectable as Column;
            if (col != null)
            {
                value.AddColumn(col);
            }
        }
        property.Value = value;

        Collection collection = property.Value as Collection;
        if (collection == null || collection.IsOneToMany ||
            collection.GenericArguments.Length != 1 ||
            collection.GenericArguments[0] != typeof(IUser))
            continue;
        IValue element = collection.Element;
    }

    foreach (ForeignKey key in persistentClass.Table.ForeignKeyIterator)
    {
        if (key.ReferencedEntityName != typeof(IUser).FullName)
            continue;

        key.ReferencedEntityName = userType.FullName;
        key.ReferencedTable = classMapping.Table;
    }
}

Check out the new SourceForge.net Marketplace.
It's the best place to buy or sell services for
