c# - 哈瓦那人的关系

Question

我一直在尝试编写一些通用代码来创建 Habanero 业务对象的 xml 包。该代码目前可以处理组合关系，但我需要手动添加关联关系。有什么方法可以以更通用的方式添加没有复合反向关系的关联关系。

组合关系是这样加起来的

    private static void AddRelatedCompositionObjects(Package package, IBusinessObject businessObject)
    {
        businessObject.Relationships
            .Where(rel => rel.RelationshipType == RelationshipType.Composition)
            .Where(rel => rel is IMultipleRelationship)
            .Select(rel => (IMultipleRelationship)rel)
            .ForEach(rel => rel.BusinessObjectCollection
                                .AsEnumerable<IBusinessObject>()
                                //.ForEach(package.Add));
                                .ForEach(bo => BuildPackage(package, bo)));

        businessObject.Relationships
            .Where(rel => rel.RelationshipType == RelationshipType.Composition)
            .Where(rel => rel is ISingleRelationship)
            .Select(rel => (ISingleRelationship)rel)
            //.ForEach(rel => package.Add(rel.GetRelatedObject()));
            .ForEach(rel => BuildPackage(package, rel.GetRelatedObject()));
    }

然后我手动添加关联关系

                var package = new Package();
                foreach (var returnDelivery in returnDeliveries)
                {
                    package.Add(returnDelivery);
                    if (returnDelivery != null)
                    {
                        var materials = returnDelivery.DeliveryItems.Select(item => item.Material).Distinct();
                        materials.ToList().ForEach(material =>
                        {
                            package.Add(material);
                            material.EWTMaterials.ForEach(package.Add);
                        });
                        package.Add(returnDelivery.Customer);
                    }
                }

首先要意识到的是1)Habanero 不需要你定义反向关系。尽管如果您从 Firestarter 生成您的类定义，您将拥有一个。

我从 Habanero.BO 的 ClassDefValidator 中窃取了这个示例片段，因此它可能不是您想要的，当然可以推广到架构中。这段代码的作用是获取 relationshipDef 的反向 relationshipDef

此代码在 Habanero.BO.ClassDefValidator 中

CheckRelationshipsForAClassDef 方法如果您查看此处，您将看到获取 relatedClassDef 的代码。将其转换成您需要的东西应该很容易。

如果你有任何问题，请告诉我。

        if (!HasReverseRelationship(relationshipDef)) return;

        string reverseRelationshipName = relationshipDef.ReverseRelationshipName;
        if (!relatedClassDef.RelationshipDefCol.Contains(reverseRelationshipName))
        {
            throw new InvalidXmlDefinitionException
                (string.Format
                     ("The relationship '{0}' could not be loaded for because the reverse relationship '{1}' defined for class '{2}' is not defined as a relationship for class '{2}'. Please check your ClassDefs.xml or fix in Firestarter.",
                      relationshipDef.RelationshipName, reverseRelationshipName, relatedClassDef.ClassNameFull));
        }

        var reverseRelationshipDef = relatedClassDef.RelationshipDefCol[reverseRelationshipName];
