Using Virtual Documents with DFC

JoanAlbert

Hello,

I'm working with VirtualDocuments. I don't know how to add and remove childs of a VirtualDocument using DFC 6.5. Can anyone help me with a sample code??

Thanks in advance

I've found a sample code for adding childs, but I don't know how to delete them with the child r_object_id...

protected void createVDM(IDfSession sess, String objId) throws IOException
   {

      try
      {
         // Instantiate an IDfSysObject object root.
         IDfSysObject sysObjRoot = (IDfSysObject)sess.getObject(new DfId(objId));

         // Before we begin, see if the root object is already checked out.
         if (sysObjRoot.isCheckedOut() &&
             !sysObjRoot.isCheckedOutBy(sess.getLoginUserName()))
         {
            System.out.println("\nError: the root object is already checked out by someone else!");
         }
         else
         {
            // Instantiate an IDfVirtualDocument from the root object.
            IDfVirtualDocument vDoc = sysObjRoot.asVirtualDocument("CURRENT", false);

            // Instantiate an IDfVirtualDocument as the root node of the VDM.
            IDfVirtualDocumentNode rootNode = vDoc.getRootNode();

            // Instantiate an IDfVirtualDocument which will be the tail node of VDM tree.
            IDfVirtualDocumentNode insertAfterNode = null;

            // Checkout the root sysobject.
            sysObjRoot.checkout();

            System.out.println("\nNow add child objects to the VDM...");

            // Prompt the user for child objects and add them to the VDM.
            while (true)
            {
               // Obtain an object name from the user.
               String objName = DfExUtils.getInput("\nEnter a child object name, 'Q' to quit: ");
               if (objName.toUpperCase().equals("Q"))
               {
                  break;
               }

               // Get the object id from a given object name.
               String childObjId = DfExUtils.getObjectId(sess, objName);
               if (childObjId != null)
               {
                  // Instantiate an IDfSysObject child object.
                  IDfSysObject sysObjChild = (IDfSysObject)sess.getObject(new DfId(childObjId));

                  // Obtain the chronicle id of child (the root version of the object).
                  IDfId chronIdChild = sysObjChild.getChronicleId();

                  // Add a node to the VDM - method args:
                  // 1. the object that is the virtual document
                  // 2. if null, the new node is placed as the first child of rootNode
                  // 3. the chronicle id of child
                  // 4. To early bind the component, specify the version label
                  // 5. Set this to true if you want to set the follow_assembly attribute to true
                  //    for the component.
                  // 6. Set this to true to use the version label
                  IDfVirtualDocumentNode childNode = vDoc.addNode(rootNode,
                                                                  insertAfterNode,
                                                                  chronIdChild,
                                                                  "CURRENT",
                                                                  false,
                                                                  true);
               }
            }

            // Ask the user for a target location for the new VDM.
            sysObjRoot.link(DfExUtils.getInput("\nEnter a Docbase location for the VDM (e.g. /Temp): "));

            // Save the VDM - this will also handle the checkin.
            sysObjRoot.save();

            System.out.println("\nVDM successfully created!");
         }
      }
      catch (DfException dfe)
      {
         System.out.println("\nError: createVDM():" + dfe.toString());
      }
   }
