How to create virtual document with DFS

tvv2000

Hi all. I try to create virtual document with DFS but do not understand how. For example I have the following content in CMS:

+ cabinet

     +root_folder

          -child_file_1

               +child_folder_1

                    -child_file_1_1

                    -child_file_1_2

I would like to create virtual document for root_folder with all children files and folders

As I understand I should specify that structure with ReferenceRelationship, but how to define it I do not know. Small example would be very useful

Thanks

ObjectIdentity objIdentity = new ObjectIdentity(defaultRepositoryName);
DataObject rootdataObject = new DataObject(objIdentity, "dm_document");

rootdataObject.getProperties().set("object_name", "My VD Root Document");

rootdataObject.getProperties().set("r_is_virtual_doc" , "1");

//Note r_is_virtual_doc is a readonly attribute and can be updated only by Superuser's

DataObject child1dataObject = new DataObject(objIdentity, "dm_document");

child1dataObject .getProperties().set("object_name", "My Child Document 1");

DataObject child2dataObject = new DataObject(objIdentity, "dm_document");

child2dataObject .getProperties().set("object_name", "My Child Document 2");

ObjectRelationship child1ToRoot = new ObjectRelationship();

child1ToRoot.setTarget(child1dataObject);

child1ToRoot.setName(Relationship.VIRTUAL_DOCUMENT_RELATIONSHIP);

child1ToRoot.setTargetRole(Relationship.ROLE_CHILD);

ObjectRelationship child2ToRoot = new ObjectRelationship();

child2ToRoot.setTarget(child2dataObject);

child2ToRoot.setName(Relationship.VIRTUAL_DOCUMENT_RELATIONSHIP);

child2ToRoot.setTargetRole(Relationship.ROLE_CHILD);

rootdataObject.getRelationships().add(child1ToRoot);

rootdataObject.getRelationships().add(child2ToRoot);

DataPackage dataPackage = new DataPackage(dataObjectRoot);

bjectService.create(dataPackage, operationOptions );
