Cascade Delete

When a persistence-capable object gets persisted to the datastore, Signsoft intelliBO will traverse the graph of referenced objects and persist all of them. Contrary to this, you will have to delete each object or list of objects separately by calling deletePersistent(...) resp. deletePersistentAll (...) at the PersistenceManager.

...
// Creating a person with an address
Person p = new Person();
p.setLastName("Smith");
pm.makePersitent(p);
Address a = new Address();
a.setCity("New York");
pm.makePersistent(a);
p.setAddress(a);
...

// Deleting the person (and its belonging address)
a = p.getAddress();
pm.deletePersistent(a);
pm.deletePersistent(p);
...

The JDO description of the addr field in the Person has to be modified like this (one-to-many mapping):

...

  <collection element-type="com.test.Address"/>
