How to revise WTPartDescribeLink?

Question

I have a WTPart object and it have some Describe link(as WTDocument) associated with it.Now I need to revise the describe link through code.

Following is the code I have tried so far

Vector localVector=new Vector();
   QueryResult localQueryResult=WTPartHelper.service.getDescribedByWTDocuments(part,false);
    System.out.println("size is "+localQueryResult.size());
    if((localQueryResult!=null)&&(localQueryResult.hasMoreElements()))
    {
        while(localQueryResult.hasMoreElements())
        {
               WTObject localObject=(WTObject) localQueryResult.nextElement();
           localVector.addElement(localObject);
        }
    }
    if((localVector!=null)&&(localVector.size()>0))
    {
        for(int i=0;i<localVector.size();i++)
        {
            WTPartDescribeLink localPartlink=(WTPartDescribeLink) localVector.elementAt(i);
            WTDocument localWTDocument=localPartlink.getDescribedBy();
            System.out.println("values are "+localWTDocument.getNumber());
            RevisionControlled localRevisionControlled=null;
            localRevisionControlled=(RevisionControlled) VersionControlHelper.service.newVersion(localWTDocument);
            localRevisionControlled=(RevisionControlled) PersistenceHelper.manager.save(localRevisionControlled);

        }
    }

This code is revising only the WTDocument object which is linked as Describelink but not revising the Describelink. If I pass the Describe link object directly like this

localRevisionControlled=(RevisionControlled) VersionControlHelper.service.newVersion((Versioned)localPartlink);

means I'm getting error message like following

Exception in thread "main" java.lang.ClassCastException: wt.part.WTPartDescribeLink cannot be cast to wt.vc.Versioned
    at ext.gt.test.CheckLink.getPartlink(CheckLink.java:100)
    at ext.gt.test.CheckLink.searchPart(CheckLink.java:52)
    at ext.gt.test.CheckLink.main(CheckLink.java:32)

I don't know how to solve this issue but I need to revise the Part describelink by code.Suggest me the API which is needed for this or some example code snippet would be useful for me.

As it is raised in the ClassCastException, WTPartDescribeLink can not be versioned. Versioned object are WTPart, WTDocument, EPMDocument, but any link object. If you want to update WTPartDescribeLink, you have to create a new version of WTPart (that is link holder). — Julien Boulay, Mar 12 '13 at 07:37

If you need to update some properties on WTPartDescribeLink, then you should create a new version of WTPart (and not WTDocument).
It can be done with the following code :

part = VersionControlHelper.service.newVersion(part);
QueryResult qr =WTPartHelper.service.getDescribedByWTDocuments(part,false);

if(qr!=null)
{
    while(qr.hasMoreElements())
    {
       WTPartDescribeLink link =(WTPartDescribeLink) localQueryResult.nextElement();
       /** ...
       Update some attributes on the link
       ... **/
       link= PersistenceServerHelper.manager.save(link);
    }
}

It might also be better to do a check-out/check-in in order to create a new iteration of the WTPart and to surround the operation with windchill transaction

:The above code gives me query result as 0 since the revision is not saved there.Also we need to check-out that part to iterate. – Vignesh Vino Mar 12 '13 at 09:36
I have a windchill service that will capture the revision of WTPart and my requirement is I need that partDescribeLink associated with that part also gets revised.I'm not supposed to check-out that part with code – Vignesh Vino Mar 12 '13 at 09:45

As I said in my previous comment, partDescribeLink can not be revised. Once your WTPart is revised, partDescribeLink is automatically reconducted on the new WTPart version. Revise partDescribeLink is not a requirement, because a link can not get a version ! What do you want to do exactly ? – Julien Boulay Mar 14 '13 at 14:49

According to the answer given above by @Julien Boulay ,I have created a method which query the the document object and then revise that document after I have created a new link with my part.

private WTPartDescribeLink getPartlink(WTPart target) throws WTException, WTPropertyVetoException {
        WTDocument localWTDocument=null;
        if(target==null)
            return null;
        QueryResult localQueryResult=WTPartHelper.service.getDescribedByWTDocuments(target, false);
        ilogger.info("size of query result is "+localQueryResult.size());
        if((localQueryResult!=null)&&(localQueryResult.hasMoreElements()))
        {
            while(localQueryResult.hasMoreElements())
            {

                 WTObject localObject=(WTObject) localQueryResult.nextElement();
                 WTPartDescribeLink localPartlink=(WTPartDescribeLink) localObject;
                 localWTDocument=localPartlink.getDescribedBy();
            }
        }

        WTDocument docm=(WTDocument) VersionControlHelper.service.allVersionsOf(localWTDocument).nextElement();
        ilogger.info("values are "+docm.getNumber());
        String version=docm.getVersionIdentifier().getValue();
        String iteration=docm.getIterationIdentifier().getValue();
        ilogger.info("Object passing with version and iteration of"+version+"."+iteration);
        RevisionControlled localRevisionControlled=null;
        localRevisionControlled=(RevisionControlled) VersionControlHelper.service.newVersion(docm);
        localRevisionControlled=(RevisionControlled) PersistenceHelper.manager.save(localRevisionControlled);
        createLink(target,docm);
        return null;
    }

    private void createLink(WTPart spart, WTDocument localWTDocument) throws WTException {

                WTPartDescribeLink link=WTPartDescribeLink.newWTPartDescribeLink(spart, localWTDocument);
                PersistenceServerHelper.manager.insert(link);
                ilogger.info("Link saved ");

        }

The above code is now works fine.
