CircularTest

public class CircularTest extends ODMGTestCase (Code)

Testing complex object graphs with circular and bidirectional references when using database foreign key settings (without support of deferred foreign keys).

The classes hierarchy looks like:
Class Shop has a bidirectional 1:1 reference with ShopDetail.
Shop has a 1:n relation with Product, Product has a 1:1 reference to Shop.
Shop has a m:n relation with Distributor.
Product has a 1:n relation to itself to handle sub-Products.

In the database the following foreign keys are declared:
- Shop has a FK to ShopDetail
- Product has a FK to Product
- Product has a FK to Shop
- CT_SHOP_DISTRIBUTOR indirection table has FK's to Shop and Distributor

Here a summery of the dependencies:
Shop--1:1-->ShopDetail--1:1-->Shop
Shop--1:n-->Product--1:1-->Shop
Product--1:n-->Product
Shop--m:n-->Distributor

Class ObjectA has a 1:1 reference to ObjectAA,
ObjectAA has 1:1 to ObjectAAA,
ObjectAAA has 1:1 to ObjectA and to ObjectAAAA,
ObjectAAAA has 1:1 to ObjectA

- ObjectA has FK to ObjectAA
- ObjectAA has FK to ObjectAAA
- ObjectAAA has FK to ObjectAAAA

Here a summery of the dependencies:
ObjetA--1:1-->ObjectAA--1:1-->ObjectAAA--1:1-->ObjectA ObjetA--1:1-->ObjectAA--1:1-->ObjectAAA--1:1-->ObjectAAAA--1:1-->ObjectA
