Fluent-Nibernate与wpf:约会使用uNhAddIns ... ObservableListType <T>默认？

Question

我试图使用Fluent-Nibernate和需要Observable集合的wpf(实现INotifyCollectionChanged接口).

在uNHAddins:NHibernate的非官方插件我找到了

    uNhAddIns.WPF.Collections.Types.ObservableListType<T>

实现INotifyCollectionChanged.它可以像这样在Fluent-Nibernate中配置

    namespace FluentNHibernateTutorial.Mappings
    {
        public class StoreMap : ClassMap<Store>
        {
            public StoreMap()
            {
                Id(x => x.Id);
                Map(x => x.Name);
                HasManyToMany(x => x.Products)
                 .CollectionType<uNhAddIns.WPF.Collections.Types
                                      .ObservableListType<Product>>()
                 .Cascade.All()
                 .Table("StoreProduct");
            }
        }
    }

有没有人知道如何使用Fluent-Nibernate 实现一个总是使用ObservableListType作为默认IList实现的约定？

更新:完美的解决方案可以替代Fluent-NHibernate-Automapper

Answer 1

像这样的东西应该做的伎俩:

public class ObservableListConvention :
    IHasManyConvention, IHasManyToManyConvention, ICollectionConvention {

    // For one-to-many relations
    public void Apply(IOneToManyCollectionInstance instance) {

        ApplyObservableListConvention(instance);
    }

    // For many-to-many relations
    public void Apply(IManyToManyCollectionInstance instance) {

        ApplyObservableListConvention(instance);
    }

    // For collections of components or simple types
    public void Apply(ICollectionInstance instance) {

        ApplyObservableListConvention(instance);
    }

    private void ApplyObservableListConvention(ICollectionInstance instance) {

        Type collectionType =
            typeof(uNhAddIns.WPF.Collections.Types.ObservableListType<>)
            .MakeGenericType(instance.ChildType);
        instance.CollectionType(collectionType);
    }
}

回答问题更新:

这个约定应该适用于automapper,如下所示:

AutoMap.AssemblyOf<Store>(cfg)
  .Conventions.Add<ObservableListConvention>();
