==@DeleteAll==
+
 
+
Use <code>@DeleteAll</code> to indicate that when an relationship is deleted, EclipseLink should use a delete all query. This typically happens if the relationship is PrivateOwned and its owner is deleted. In that case, the members of the relationship will be deleted without reading them in.
