Best practice for Handling NHibernate parent-child collections

Question

So in a typical model where you have a parent that can have many children and a child that can have only one parent, how do you manage the adding of children. I have been u

Answer 1

I don't like all the extra AddXXX() and RemoveXXX() methods cluttering my entity interfaces. Instead, I have a custom list that raises events when the Add() and Remove() methods are called.

The linking then happens in the event handlers:

public class Course()
{
   public Course()
   {
     this.Topics = new EntityList<Topic>();
     this.Topics.AddItem += new AddItemEventHandler<Topic>(Topic_AddItem);
     this.Topics.RemoveItem += new RemoveItemEventHandler<Topic>(Topic_RemoveItem);
   }

   public EntityList<Topic> Topics { get; private set; }

   private void Topic_AddItem(Topic item, object args)
   {
     // Replace with your linking code:
     EntityLinker.Link(this).With(item, args);
   }   

   private void Topic_RemoveItem(Topic item, object args)
   {
     // Replace with your unlinking code:
     EntityLinker.Unlink(this).From(item, args);
   }   
}
