Question

我有一个WTPart对象，它有一些与之关联的Describe链接（作为WTDocument）。现在我需要通过代码修改describe链接。

以下是我到目前为止尝试过的代码

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);

        }
    }

此代码仅修改WTDocument对象，该对象链接为Describelink但未修改Describelink。如果我像这样直接传递Describe链接对象

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

表示我收到如下错误消息

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)

我不知道如何解决这个问题，但我需要通过代码修改Part describeelink.Suggest me这个或一些示例代码片段对我来说非常有用。

如果您需要更新WTPartDescribeLink上的某些属性，那么您应该创建一个新版本的WTPart（而不是WTDocument）。
可以使用以下代码完成：

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);
    }
}

为了创建WTPart的新迭代并使用windchill事务包围操作，执行签出/签入也可能更好

根据@Julien Boulay上面给出的答案，我创建了一个查询文档对象的方法，然后在我创建了一个新链接之后修改了该文档。

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 ");

        }

上面的代码现在运行正常。

如何修改WTPartDescribeLink？
