NHibernate Free Mapping - Status Template

Question

I'm not too hot at NHibernate / FNH Mapping, but I am looking at implementing a state template and, like the idea of ​​Derick Bailey's article here:

I believe this was a long time ago, so the mapping code is out of date, can someone give me a hand to update it for FNH 1.1?

public class OrderStatusMap: ClassMap<OrderStatus>
{
   public OrderStatusMap()
   {
       CreateMap();
   }

   public void CreateMap()
   {
       DefaultAccess.AsProperty();
       WithTable("OrderStates");
       Id(s => s.Id).GeneratedBy.Assigned();

       DiscriminateSubClassesOnColumn<string>("Name") 
           .SubClass<InProcessStatus>()
               .IsIdentifiedBy(OrderStatus.InProcess.Name)
               .MapSubClassColumns(x => { }) 

           .SubClass<TotaledStatus>()
               .IsIdentifiedBy(OrderStatus.Totaled.Name)
               .MapSubClassColumns(x => { })

           .SubClass<TenderedStatus>()
               .IsIdentifiedBy(OrderStatus.Tendered.Name)
               .MapSubClassColumns(x => { })

           .SubClass<DeliveredStatus>()
               .IsIdentifiedBy(OrderStatus.Delivered.Name)
               .MapSubClassColumns(x => { })

       Map(s => s.Name);    
   }
}

His article is here for the rest of the code: http://www.lostechies.com/blogs/derickbailey/archive/2008/11/26/mapping-a-state-pattern-with-nhibernate.aspx

Many thanks!

Answer 1

I am using 1.1 and this is the syntax.

public class OrderStatusMap: ClassMap<OrderStatus>
{
     public OrderStatusMap()
     {
           DefaultAccess.AsProperty();
           WithTable("OrderStates");
           Id(s => s.Id).GeneratedBy.Assigned();
           Map(s => s.Name);
           DiscriminateSubClassesOnColumn<string>("Name");
     }
}

public class InProcessStatusMap : SubclassMap<InProcessStatus>
{
    public InProcessStatusMap()
    {
         DiscriminatorValue(OrderStatus.InProcess.Name);
    }
}

public class TotaledStatusMap : SubclassMap<TotaledStatus>
{
    public TotaledStatusMap()
    {
         DiscriminatorValue(OrderStatus.TotaledStatus.Name);
    }
}

etc...
